Ubuntu :: Wireless BCM4322 Slow Connection
Oct 13, 2010
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?
10.10 64 bit. Using Broadcom restricted drivers (wl)

I was praying a standard install of Ubuntu 10.04 would work out of the gate and I was wrong:- Looks like everything is working except for my wireless adapter, Dell E4300

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:

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 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 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 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.

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'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.

Just re-installed Bodhi. Ran update, dist-update, set up connection and connection still slow or timing out and reporting errors in 'iwconfig'. This is 3rd re-install of this version. Have also tried 3.0 kernel and pae versions of Bodhi. Cannot get this connection up to speed and without errors. Atheros chipset ar9271.
Sorry for weird subject line and opening paragraph. Trying to make it easy to find and browse in case this gets solved and can help someone else. Not being a Linux guru, I can only hope to help others through my mistakes and ignorance.
I followed instructions to update driver listed at Linux Wireless.
In addition to following the directions at Linux Wireless, I also downloaded the GUI Program to install ath9k_htc.
No luck. My connection reports 1M/s and is reporting "invalid misc:" errors in iwconfig.
I'm running Midori browser but apt-get and wget are also downloading slowly.
I'm connecting to a Zyxel 660 series router using WPA/WPA2.

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.

i would like to make the switch to fedora but before i do want to find out whether i will have the same problem that i had with ubuntu in Fedora. Problem with Ubuntu:- The only way of running o/s ati drivers to optimise hd3000 series (r600) graphics card and opengl was by running kernel 2.6.32rc6 which renders the broadcom bcm4322 wireless card unoperational. Fedora 12 looks promising but i would like to know whether there is support for Broadcom bcm4322 wireless cards and how hard they are to get up and running.

I'm having problems with (no surprise) my Broadcom BCM4322 Network Adapter after a clean install of 9.10. I am just about tearing my hair out.
1. I downloaded Broadcom's provided Linux drivers. No joy.
2. I installed first the STA package, then b43-fwcutter. No joy.
3. I installed NDISwrapper, but cannot find the .inf file I need. Anyone? I dual boot with Vista, so I went into my Windows system and pulled a .inf file from the driver files there (bcmwl6.inf), but NDISwrapper said it was not valid. I have looked all over the web for a .inf driver file for this chipset but cannot seem to find anything (all I can find is .exe files).

I was trying to get the b43 driver work with my broadcom bcm4322 wireless card. I changed the kernel from 2.6.32 to 2.6.38 in order to make the b43 driver to work. When I booted with the new kernel the internet stopped working so I looked for a solution. I don't remember which website I went but it said that I have to re-install the STA drivers so I did that and rebooted and nothing happened. I decided to go back to the 2.6.32 kernel and re-installed the STA drivers. The wireless card (eth1) isn't showing when I run the command iwconfig
Code:
xavi@xavi-laptop:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

I have a Acer Revo R3610 nettop on which I installed oS11.3. It has an Atheros AR5001 wireless network adaptor.I'm getting very bad latency and throughput on with this card. In comparison my Thinkpad with Intel card achieves at least 10 times the throughput from the same location. Also when I boot my wifi will come up authenticate and then a few seconds later disconnect and reconnect. I've tried updating the kernel to 2.6.35 as one of the fixes was to improve the performance of the ath5k driver. I'm using wpa2 authentication.
Here are some details:
Code:
mediacentre:~ # /sbin/lspci -nnk

Subsystem: Acer Incorporated [ALI] Device [1025:0222]
[code]....
Is there anything else I paste that will help determine the cause of the bad throughput. Browsing the web or copying files across the network is bordering unusable.

I have a Dell-made, Broadcom-based wireless card, BCM4322. I'm using Broadcom's proprietary drivers from RPM Fusion.
Code:
lspci | grep -i broadcom

Since installing F11, I can no longer connect to WEP-secured wireless. When I use automatic IP settings, the connection simply times out. When I specify an IP, Netmask, Gateway, and DNS server, NetworkManager thinks the connection properly established, but any pings time out, even when I don't specify a hostname (just an IP address). I can connect to (and use) unencrypted wireless. I haven't tried other encryption schemes. The WEP index is 1 and it's non-authenticated (open). I've been playing with the settings for over a week now with no success.

I haven't done Linux since before it had Wireless support, and have never had to tinker with network settings, so I am at a loss.My searching may be weak, but when I tried, I found nothing relevant except to determine some of the things usually asked for in threads of this nature.The symptom is very slow connection when using wireless, but it does fine when I hardwire it. Using Windows 7 on the same system it flows nicely.

I have managed to compile and load the RaLink drivers for my wifi card and get an internet connection.My problem is that when I do a broadband speed test on using chrome I get about 1.5 Mbs and on my laptop (Windows 7 meh :-( ) its closer to 7Mbs. I was wondering if there are any other settings I can modify or tweak that could potentially change to improve this. or maybe a better way to test the through put of my connection?I downloaded the latest drivers for my device from Ralink and compiled new module, but I get a little confused on what settings to do and where it reads any configuration information from.
Also this may be off topic or thread, if so I apologise, but I am sure there is a quick answer to this and there is a lot of different information out there on where and how I load my new rt3562sta.ko module into the kernel on start up. As currently I am calling insmod on it manually every time I start up then the Network Manager picks it up and connects.

I can't get my Broadcoam BCM4322 to connect to a protected access point. I've tried the drivers from rpmfusion, and tried to build the module with the source+binary package from Broadcom, all with no luck. The failure seems to happen during the WPA negotiation.
I haven't tried connecting to an unsecured WiFi access point.
When booting this same laptop to Kubuntu 9.04, it can connect to secured, so it is possible under linux.
Here's output from lspci, and the tail of the log while KNetworkManager is trying to connect the device.

My girlfriend running on windows xp dont have any problem with the connection.
I disable the ipv6 of firefox and grub but it still doesnt change anything.
I'm not a linux expert so if you want any report juste tell me how to do it and I will try to give you more information.
