Ubuntu Networking :: Slow Wireless Connection With Intel 6300
Dec 30, 2010
I want to connect to a 300mbit network (802.11n). With Windows (the same Computer) I am able to connect with full speed, but with Ubuntu Maverick (64bit), and a lot of other distros I tested, I am only able to connect with 54mbit. The builtin wireless network card is an Intel Corporation Centrino Ultimate-N 6300 (rev 35). Is this a driver Problem? I updated to kernel version 2.6.37-rc2 via ppa sources, but with no luck. I tried to extract the windows driver and started it with ndiswrapper, but i properbly made somethng wrong, because the card did not show up, though ndiswrapper said adapter available... oO?

I upgraded the wireless card in my laptop (sony VAIO CW) due to the original Atheros being incurably slow.The new card is an Intel 6300 ultimate n. In Windows 7, after installing the relevant drivers everything worked without a hitch.In my Ubuntu 10.04 installation, however, I have been unable to get it working.Initially I had the compat-wireless modules installed (linux-backports-modules-wireless-generic), as I had done so to try and get the Atheros card working better. I tried removing all of these, and that made the difference that iwconfig now (instead of nothing) listed
Code:
wlan1 IEEE 802.11abgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=16 dBm

Alright this is my first post on here and I hope I got sufficient Information for you available. I ran Ubuntu based Distros before but this is the first time under a Debian based Distro for me. I got a newlaptop and this one does not seem to let me get my wireless to work after multiple efforts
My problem: My Intel Centrino N-6300 () does not seem to find any network connections.
My previous attempts: (Some of which required me to reinstall Suse)
1. I installed new kernels as my first assumption was that the kernel was not supporting it. I know now that it is supported.
2. I installed drivers from http://intellinuxwireless.org/ which was pointless.
3. I installed backports (THat was still under Linux Mint. Same problem there.)
4. I tried NDiswrapper without success.
5. I checked rfkill as you can see further down below.
Alright here are some of my info's I have collected so far. Let me know if anything is missing.
RFkill:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

To make Intel Centrino Ultimate-N 6300 wireless card work on ubuntu, you just need to download the firmware from here decompress it and copy the ucode in /lib/firmware. This works in jaunty. My laptop is a HP Elitebook 8440p.

Since I've updated from 9.10 to 10.04, I'm having some difficulties to use the internet. Even though I can connect to my home wireless network, the connection is really slow. I've got a Dell Inspiron 1545, and here comes the configuration:
Code:
sussa@sussa-laptop:~$ sudo lshw -C network
[sudo] password for sussa:
*-network
description: Wireless interface
product: Wireless WiFi Link 5100
vendor: Intel Corporation
physical id: 0 .....
Apart from that, I must say that Ubuntu 10.04 is fantastic. Easy to use, elegantly designed and working perfectly on my PC

I am running Kubuntu 10.04 (32-bit) on a Sony VAIO VPCCW23FX, when I connected to my router through Wireless the connection is too slow and random, 3 kB - 50 kB. But when connect to the router through Ethernet cable I get the normal speed 265 kB. I read many posts but can't find solution, and already updated all packages. the Wireless card is:
Code:
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
the output of iwconfig:
Code:
wlan0 IEEE 802.11bgn ESSID:"zzzzplw9"

Noob to Ubuntu here and I cannot access my wireless connection. It is working fine right now (wired) but I am using the TV stand as my computer desk right now so... not very practical. I tried following the "howto post a wireless issue (ticket)" but there was too much information for me to be able to put on here.
I have my SSID and my WEP. I am on Verizon DSL (only provider in my area). I tried using the wireless setting in network connections and I tried using DSL. I assumed that SSID+Password=Yay the internet works! but apparently not.

I just got a wireless card and I've been having connection issues under Linux. The chipset I have is a Ralink 2860 (the card itself is an Asus PCE-N13) and supports 802.11n speeds up to 300 mbps. I am connecting to a DLink DIR-655 router, which also supports 802.11n at 300 mbps. I get full bars when connecting to my router, and my router's connection information shows my computer connected as 802.11n with the signal at around 80%, but the data rate is usually around 5.5 mbps. (I've rarely seen it go up to 18 mbps) I can confirm this woefully slow speed with anything I try to do over the network. Additionally, my wireless connection will sometime be disconnected and network manager will often fail to connect. When it fails to connect, my router lists my comptuer with the correct IP address, so I know it is successfully connecting to the router and the router is accepting the connection, but network manager seems to not recognize this.
I am running Debian Squeeze (testing), but I have a custom kernel, which is 2.6.35 and is using Debian's kernel configuration. I have the newest firmware from Ralink's website, and I also tried the newest drivers, which made no difference. (I have since removed those drivers, since I'd prefer to use the drivers supplied with the kernel if possible, but I can install them again if necessary) I put this card in my main computer and booted under Windows, and it was able to connect with 100% signal (it's right next to the router) and at 300 mbps. I also tried it under Debian on my main computer (with the stock 2.6.33 kernel), but it only connected as 802.11g, and even at 100% signal it was only connected at 36 mbps. For comparison, my laptop with an 802.11g card and running Mac OS X can achieve the full 54 mbps at 84%.

I have a problem with my wireless where when running the laptop from the battery the connection is very slow. When the laptop is connected to the power supply everything is fine, but the moment it's disconnected and run on the battery the speed drops when browsing the Internet or accessing files on other computers on my network.
The laptop is a Samsung SF310
Wireless chipset is BCM4313
Code:
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g LP-PHY (rev 01)
Subsystem: Wistron NeWeb Corp. Device 051a
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at f4c00000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: wl
Kernel modules: wl
In attempt to fix this I installed the latest drivers from the Broadcom site using this guide. When I enabled these drivers everything worked well. I did speed test and got the same speeds I get when connected via Ethernet:
Ping 51ms
DL 4.31
UL 0.65
So I set the drivers to load at boot using this forum post as a guide as the steps in the Broadcom guide didn't work and rebooted the laptop on battery power. The wireless connected fine, but the slow speed problem had returned. Running a speed test got the following results
Ping 235
DL 0.54
UL 0.30
So I ran iwconfig when running from battery and then from power supply.
Code:
xxxx@xxxx ~ $ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
eth1 IEEE 802.11 Access Point: Not-Associated
Link Quality:5 Signal level:215 Noise level:160
Rx invalid nwid:0 invalid crypt:0 invalid misc:0
As can be seen the signal quality is 5 and signal level 215
Code:
xxxx@xxxx ~ $ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
eth1 IEEE 802.11 Access Point: Not-Associated
Link Quality:5 Signal level:214 Noise level:164
Rx invalid nwid:0 invalid crypt:0 invalid misc:0
And when connected via the power supply the signal level is 5 and signal level 214. There may be some kind of power saving issue, although there are no relevant setting in the BIOS and I can't see anything in the various wireless control pannels. I have other wireless drivers and there are no problem with those.

Since upgrading to Ubuntu 11.04 my wireless connection has been extremely slow. The same happened with 10.10. Although that was quite different. Back then everything within my network moved slowly, but now it doesn't affect my web browser. It seems to have only slowed the application centre and update manager. I am still waiting for the flash plugin to download and install for testing ....., but I am torrenting Ubuntu 11.04 right now and have actually hit the limit of my bandwidth (1.1 MB/s) whereas the speed in the software centre and update manager was in the region of 45 kb/s.
I'm not sure if this is because I have installed extra drivers found here after I did some research.
Although my web surfing is fast and stable, I would like to get my updates and applications downloading properly. Does anyone know what I can do?
From my 2-hour googling spree I know you may want the results from the command "lspci"
Code:
root@Felicia:/home/silkworm# lspci
00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)

I have installed Fedora 12 OS which is using kernel 2.6.32.11-99.fc12.x86_64. I am using a Linksys WMP600N Wireless-N PCI Adapter with Dual Band card which has a Ralink chipset. I have installed the latest rt2860 driver which uses the 2.6.32.11-99.fc12.x86_64 kernel. If there is any other pieces of information that is need I can provide it.
Problem: I can use either the Ethernet connection which is built into my ABIT mother board or my PCI wireless card. My Ethernet connection works perfectly however; my wireless card comes up attaches to my wireless router; that's it. There is a strong signal, the WPA2 security password works correctly. I am able to ping my loop-back address and my DHCP IP address for my wireless card but I can not ping the router or anything outside of my box.
If I let the ping program run for a while and allow it to try to ping the router, after a period of time ~5minutes or so I will get several hits and then stop. The firewall does not change from my Ethernet connection to my wireless connection. The Wireless connection is a trusted interface in my firewall specifications. Questions/Thoughts:
Can I use the same OS provided routing table for my Ethernet connection for my wireless connection? Would the OS know which port to use by switching to a wireless connection (after reboot)? Do I need to somehow switch or bridge the port? Is the wpa_supplicant playing with my connection and opening it up and then shutting it down? Below are some netstat data: routing, interface table, statistics, and dmesg on the kernel driver rt2860.

I am new to fedora, but not so new to linux. I've got f13 installed on my netbook, and the speed and overall beter-ness? of it made me want to get it going on my desktop. I've installed, and have updated the kernel, and network manager (Along with a few other things). My problem is this; after about an hour or two I get a drop out, unable to reconnect. Until I use 'ifconfig wlan0 down > ifconfig wlan0 up' then it works great for about 10 minutes, slows down, and eventualy drops out. i updated networkmanager in the hopes it may have been that, but it really made only a slight difference.
iwconfig :
$ iwconfig wlan0
wlan0 IEEE 802.11bg ESSID:
Mode:Managed Frequency:2.462 GHz Access Point: 00:1E:2A:0E:08:50
Bit Rate=54 Mb/s Tx-Power=18 dBm
Retry long limit:7 RTS thr: off Fragment thr: off
Power Management: on
Link Quality=32/70 Signal level=-78 dBm

I am using a linksys wusb54g > chipset ralink rt2510? (don't quote me on that its from memory). I am also using WPA encription. I am currently messing with those setting to see if that helps.

I'm having problems with my wireless. It connects without any problem, but it is very slow. Actually I have the impression that the connection velocity is varies from normal to very slow, however the average connection velocity is very slow. I have been looking up the forums for more the one month with any success. I have tried to install the compac-wireless drivers and the kmod-wl with many different network setups. For sure it is not a problem with my home network, since it works fine with my other old notebook running fedora 11 or when I boot in the windows.
My system configuration is:
- sony vaio VPCCW23FX
- card: Atheros AR9285
- driver: ath9k
- operating system: fedora 12 - kernel 2.6.32.12-115.fc12.x86_64

I am a convert from Ubuntu (9.04 kept freezing on my laptop; when it did work, many packages it seemed were outdated--ie only Eclipse 3.2, rdesktop was messed up [and apparently is also in Fedora]), and I am having some trouble with getting my wireless working.I am running Fedora 11.First off, there is a problem when trying to connect when using DHCP. NetworkManager gets to the second green dot, and then after a short while I am given a message that the connection was disconnected.
Configuring the interface manually, not using DHCP, allows the connection to complete. However, the internet is very slow. There is a 15-30 sec delay before website loading actually commences, and then another delay each time an ad must be fetched from another server.How can I fix this delay? I know I have encountered it in earlier versions of Ubuntu, but I can't remember how I fixed it.About the rdesktop problem, if anyone is able to help [maybe I should post another thread?], the cursor color (the color of the pointer) is inverted---where it should be white it is black, and where it should be black it is white. I use rdesktop a lot to connect to my terminal server in my basement. Any idea how to fix it?

I'm running Fedora 12 on an Acer Aspire One with KDE. The built-in wireless works without a problem EVERYWHERE except at work. It's a shared wireless connection using WPA/WPA2 security.I can connect but it's "hit-and-miss" if I can do anything with it. Somedays it works well for a few minutes then has a period of inactivity - then slow - randomly receives...It worked flawlessly when the computer was running Windows7 no one else has connectivity issues but I'm the only one using Linux.

I have search the web quite a while about issues with the Intel Dual Band Wireless-AC 7260 Wi-Fi/Bluetooth card. It seems plenty of people have trouble (or at least have had trouble) with it. I do have a working connection, device seems recognized etc, but it works only at a very low/annoying speed.I'm running Wheezy backports and I have firmware-iwlwifi ver 0.43 installed (from Debian testing).
Below is some system output
Code: Select all$ uname -v
#1 SMP Debian 3.14.7-1~bpo70+1 (2014-06-21)
$ dmesg | grep iwlwifi
[ 1.784455] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X

[ 1.809713] iwlwifi 0000:03:00.0: loaded firmware version 23.214.9.0 op_mode iwlmvm

I'm not sure why modinfo iwlwifi only lists firmware iwlwifi-7260-7.ucude while in dmesg you see iwlwifi-7260-9.ucude loads.

Are Intel wireless cards compatible with non-intel-based laptops? In my case I wish to upgrade the current Atheros-based mini pci express wifi card with the Intel 4965agn. It is an Asus 4520 with an AMD Athlon X2 processor and nvidia nForce chipset.

I've noticed that my wifi connection is significantly slower than my wired connection. Obviously wired is always faster, but when I boot in to windoze or use Mac, the difference between wired and wifi is negligible. I'm running Debian 8 testing on a Lenovo X201 with Intel Corporation Centrino Wireless-N 1000 [Condor Peak] network card.

I am having problems with the wl driver for the BCM4322 on 10.10.
It seems with two different routers the connection is really slow and jumpy and web pages barely want to load. I have tried a usb wireless device, and it seems to work much quicker.
Is anyone else having problems with their broadcom cards with the new update?

Basically the problem is a slow download speed over my wireless connection that does not occur in Windows Vista. The reason I'm so annoyed is that the speed is not constantly slow. It bursts at around 600kb/s (good for my internet connection). The problem is that while trying to download a file it bursts for about a second,then total throughput decreases to +/- 1kb/s for a few seconds, then another burst and so on. Note the file I'm downloading is a http:// download, not p2p or anything. I've attached a screenshot of the System Monitor.

Some additional info. I'm using Ubuntu 10.04 with all available updates installed. The browser in use is Google Chrome.

I am experiencing very slow speed with the Intel 5300AGN on a Dell Studio XPS notebook and the iwlagn driver. I'm using Fedora 12 with all the latest updates available. When connecting to a G network with WPA2 security, everything goes fine at "normal" speed. When connecting to a N network with WPA2 security, the download speed falls between 0 k/s and 20 k/s max. The connection speed (as stated by Network Manager and iwconfig) is between 0 kb/s (?) and 11 Mb/s during the same session. I'm can't connect through ssh or download with scp (stalled). Web pages take a lot of time to render.
When connecting to the same N network on Window 7, everything runs fine enough. Every N network I try is the same story. Works fine on windows, badly on F12..

I have lenovo thinkpad, T61 with Intel 4965AGN wireless card. It is a N card, it works under N mode in windwos, but not in Ubuntu (10.10). I installed ndiswrapper and got the windows xp drivers for this card. the issue is that i got an error when installing the drivers and since then I cannot use wireless.
The error i got is: Code: Module could not be loaded. Error was: FATAL: Could not read '/lib/modules/2.6.35-24-generic/kernel/ubuntu/ndiswrapper/ndiswrapper.ko': No such file or director I unistalled the driver, but now under network connections no wireless connections appear, nothing.

I just installed ubuntu as my primary OS, but I have the disk with XP on it and I don't want to go back, but I need faster network connectivity. I have a T60p with Intel Gigabit jacked into my Gigabit router which also has my desktop (running XP) and my NAS. If I FTP files from my NAS (or SCP), I get transfer speeds around 250-500 KB/s (which is not very fast). On this same switch, from my XP desktop I get transfer speeds around 12 MB/s. I get the same speeds using my 802.11n card (Atheros) as with the ethernet NIC (250-500 KB/s).The drivers for the ethernet card and the atheros card are e1000e and ath9k respectively.I have disabled IPv6. Since the problem occurs using either interface, I am just going to concentrate on fixing it for the Ethernet interface (since I believe it to be a systemwide problem).
Code:
skinnersbane@albert:~$ sudo ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
[code]....
Clearly my card is running at Gigabit, but why the bad transfer speeds? I am using filezilla for FTP (technically FTPES). I closed every other program. My CPU utilization does seem high and I wonder if this is part of the problem. I had no problems with throughput using either interface in Windows XP just one week ago.

No improvement since I first reported this problem, I am hoping somebody can now advise.
Using openSUSE11.3 Linux 2.6.34.7-0.5-default i686 with kde 4.4.4 release 3.Problem is the wait of sometimes over 2 minutes before the wifi connection is available.Two questions:-
1. Why does it take so long? Longer by far than it to be with previous openSUSE releases. Much longer than with that other OS!!!2. How do I remove the wallet process. Not needed in present environment so I would like direct connection without having to open wallet. I didn't set this up, it just happened after I had upgraded to 11.3 and I need to know how to disable it to save time.

I've just installed F12 64bit on my notebook. Everything works great. Only problem I'm having at the mo is my WLAN is slow at DNS resolution. On wired it works fine. I know it's not my access point as it is part if my router and I've rebooted it a few times. My other wireless notebook (Windows 7, Intel 3945ABG) doesn't have the same issue, and this notebook didn't when on Windows 7. I'm using OpenDNS as my forwarders.When I open a URL in Firefox (3.5.5) it opens the site immediately on wired. On wireless it will sit for 3-4 seconds before opening the site saying looking up .................. Once on the site browsing behaves normally.Anyone else having similar issues?

A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.
