Ubuntu Networking :: Slow/intermittent Connection On Linksys Wmp600n - Wubi 10.10
Oct 28, 2010
i have just installed 10.10 under wubi, first time trying to use this network card under ubuntu. works fine on XP where it connects with good signal strength to a zyxel p-600 b/g router (my 3 other machines also connect fine to this router)
i am using WPA2, it takes 30secs to 1min to connect in the first place, then runs slowly and with intermittent disconnects, reports good signal strength in network manager.
i have been fortunate enough to have 3 machines that run ubuntu flawlessly out of the box..

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.

/sbin/lspci reports this: 01:00.0 Network controller: RaLink RT2800 802.11n PCI iwconfig reports nothing Network manager doesn't see it. The card works when I run it from Win 7. I tried rt2800 and rt2860. no results I am fairly new to Linux and I don't know all of the command line functions, How to get my wireless PCI card detected. After I installed the rt2860 driver, I didn't reboot. After rebooting, the card lit up and now I am functional. Woo Hoo.

I tried out ubuntu and I was beyond impressed with this OS. I decided it was time to do a complete migration to ubuntu. I installed Ubuntu 10.10 on my HP laptop and everything went great. It detected all the drivers and my laptop is working in tip top shape. I decided to install ubuntu on a custom PC I recently bought (used for Java development), and that is when I started to run into problems. These are the specs on my custom pc:
[Code].....
I am using Ubuntu 10.10 64-bit edition on the system. First problem I am having is there is no audio on my system. For this card I'm using an HDMI cable to connect it to my screen. I installed the NVIDIA proprietary drivers and there was no audio. I reverted back to drivers I found on the NVIDIA website and still there is no audio. Second problem I am having is attributed to the wifi card I am using (I think). I keep getting this message on boot after post (and on the terminal after I switch off the X server by stopping gdm):
[Code].....
However, after the system boots I can connect to the internet.

How to get the Linksys: Wireless-N PCI Adapter with Dual-Band (WMP600N) working under FC10 with WEP encryption and linking up to a 54Mb/s Network. Hardware : D945GCLF2 with Intel atom330, 2G memory. As I got to this in a roundabout way, I would recommend that you follow the following steps and see if somewhere along the line your wireless starts working.
1: Get the latest driver from Ralink: [URL] In my case 2009_0918_RT2860_Linux_STA_v2.2.0.0.tar.bz2 (the line starting with RT2860PCI) Unpack, read the README_STA file and follow the instructions. Do: make && make install After this I could only get a wireless connection by doing:

I bought the wireless PCI network card WMP600N from Linksys. I tried to connect with my router, but no success. The correct driver is installed(RT2800), the necessary package WPA_supplement is also installed. My providers settings are WPA-PSK with a shared key. Key encryption is TKIP. I can't choose TKIP in the Yast network menu. so i chose passphrase.
the weird thing is that the wifimanager says WEP is on but it's not, at least not in my router and i did not setup WEP to. see picture 6. i had to use manual boot "ifup wlan0" because when i use boot at startup the whole systeem freezes. anyway, when i use ifup wlan0 as root in the konsole, the system also freezes. i have explained it clearly, please take a look a the pictures.
step1
step2
step3
step4 After pressing enter the system freezes.

I'm having some trouble connecting to the wireless network here at home. The PC has a Linksys WMP600N wireless network card, which works fine under several versions of Windows. In Opensuse however, I cannot get it to find the network. Even though my laptop is right next to it, which has perfect connection to the network. The router is a Linksys WRT610N.
I've tried running iwconfig and iwlist scan in the terminal, but the scan returns no results and iwconfig indicates it does not have a connection to a network. I've turned off IPv6 as I read this can sometimes cause issues. I've also tried issuing the computer a static IP address, figuring the DHCP might be causing problems, but all to no avail.

Using my usb mobile broadband dongle I am able to access the internet about 25% of the time. I am able to make a connection to the '3' wireless network 100% of the time, but often Mozilla and all other applications that rely on an internet connection do not recognise that this connection has been successfully established, and give me error messages claiming there is no internet connection.
I can't discern any pattern as to whether the connection will be recognised or not. When it isn't recognised, the only solution is to disconnect and reconnect to the network. Sometimes this works and sometimes it doesn't. Sometimes restarting the computer fixes the problem, and sometimes it doesn't. I also have access to a wireless network at uni. I have no problems using this network whatsoever. Housemates using the same dongle on Windows have no problems. I'm using an Acer Aspire one, the dongle is a Huawei e220, I'm running Ubuntu 9.10. I have only recently reinstalled the operating system and have not needed to mess around with any network settings to get the usb dongle to 'work' the way it is currently.

I've got UNE 10.10 installed on a Samsung N150 that uses the RTL8192E for wireless. When the wireless works then it generally works okay, but I'm having problems with reboots and long-running connections. This is different to the mass of posts (mainly from 2009) about the card not working at all, so I started a new thread.Basically, 90%+ of cold boots result in a successful wireless connection, with Network Manager remembering my WPA password.
When the wireless is up then it never obviously drops out, but I've got an app with a long-running connection that seems to disconnect itself occasionally. Looking at Wireshark then it appears that there are a number of retransmits, and a big batch just before it disconnects (which implies that the app is dropping its connection because it thinks the other end disappeared). Running the app on another machine with a different card but through the same release of Ubuntu and the app and the same router doesn't result in retries or drop-outs.On the times when a cold boot doesn't successfully reconnect then it asks for the WPA password, then continues trying, then asks for the WPA password again, then continues trying, then asks...and so on until I rmmod and modprobe the driver.
I originally had problems with the machine refusing to restore after a hibernate/suspend, but this was solved by a tip to rmmod the driver on hibernate/suspend and modprobe it on restore.The wireless will now work okay on some restores, but is more likely to repeat the behaviour described above for the failed cold boot.
Code:
$ lspci -nn
...
05:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8192E Wireless LAN Controller [10ec:8192] (rev 01)[code]....
Attached is a file with some snippets from dmesg around the time of the wireless failure, and the log of what it does after a remove and re-add for comparison of the "correct" messages.

In the last week I have noticed that sometimes my Mobile Broadband connection just goes off without me doing anything! I have credit on the dongle account, so it isn't that. I'm using fedora 14 on an acer aspire one netbook. Dongle is a Huawei E160 on o2 here in the UK Kernel is 2.6.35.11-83.i686.fc14
Sometimes unplugging and replugging the usb dongle works. Othertimes, I have to leave it out for several hours. It does seem to happen daily, though.

I'm having problems with my internet connection; it seems to be working fine then every other click of a page there is no connection, then I click it again a second later and it works. I am using a wired network connection plugged into an addon wireless router.
When I use ping under network tools it seems to be fine, then freezes halfway through and doesn't receive those few packets, giving me a transmission percentage of about 70%.

I have a Dell laptop with a bcm4312 wireless card. Every once in a while though, the laptop is unable to send or receive any data for 30 seconds. The connection is not dropped, and nothing shows up in any system logs. Both the wl and b43 drivers have this problem, but it works fine under vista.

I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.

I just installed 10.10 (2.6.35-24-generic) and my wired network connection is cutting out. I'm dual booting with Windows 7, and it works fine over there. I'm confident it's not a hardware issue. It works initially, but after a few minutes (this varies) the connection will drop out. If I'm on Firefox, I'll get "Loading" until the connection times out. If I'm using RDP to a local computer, I'll lose the connection. When it happens, if I ping a local computer, I'll get:
[Code]....
So I'm getting a bunch of packet loss. Some of the time, once the packets do start going through again, Firefox will finish loading the page. Other times, I have to click on network manager and click on "Auto eth0" which will give me the "connection established" message, and kick the network card back into gear. Sometimes I have to do this several times. It never shows as disconnected, but this somehow gets it going again.

I have a core i7 machine on which I have dual booted Ubuntu 10.10 and Fedora 14. I am facing a weird problem on both the Linux distributions. Currently, I am facing three major problems which are causing me to use my laptop instead of this machine.Most of the times the sound gets distorted ( like the tempo is very slow and some cracks), but some other times it just works fine. ( I experienced this on both Ubuntu and Fedora)Internet at times is very fast and works great, but suddenly it slows down and takes a whole lot time to load. sometimes it just never gets fast.The low resolution flash videos, gets this very weird high pitch sound
Also, I noticed ( I don't think there is a relation between the two or is there?) that whenever the internet is slow, the sound is also distorted and when internet is fast sound works great.The intermittent nature of the problem is making it difficult to debug.

Over the past two months I've migrated two NetWare servers 6.5 SP7 to SLES10 SP3 and OES2 SP2.'ve had some consulting assistance and been learning linux as I go. Now I have a b!tch of a problem with a Dell PE SC 1430 with integrated Broadcom BCM 5751 GB Ethernet working ok, but then after a reboot it will come up with no networking. I've used Network Manager to configure a static IP but it willsometimes come up and ifconfig will show no ip assigned.I can manually assigned ip, netmask, gw and can ping the gw, but can't ping any host on the subnet. I disabled the integrated NIC and installed another, but same problem.

The shares get mounted correctly and you can navigate through the directories and open files.The only problem is that it randomly starts going really slow taking 30 seconds or longer to open a directory that has 2 or 3 files in it.I have tried quite a few things to try and fix this without any luck. Its getting to the point where I am having to consider recommending that we use windows instead, which I would rather not do as I think its good for students to experience different operating systems during school.

Is anyone having problems since they updated? My card was working fine before I updated. Now it detects all the networks, including mine. However, when it tries to connect it sits there for ~2 minutes, then says it's disconnected. I've checked my security settings and they are fine.

From time to time I have no connection to the net after booting the machine. This is a wired connection that goes through a switch, then a router to a DSL modem. When there is no automatic connection, I can't connect manually either However if I re-boot the connection works normally.
The Network Connection indicates eth0 and eth1 are both set at "Auto" Strangely the "Last Used" column indicates "Never" for both even when I am actually connected, and on line.

I'm running Ubuntu Karmic on my desktop machine which is connected to my wireless router (via LAN cable).
I have two laptops on the LAN as well. One is my wife's Windows 7 laptop and the other is my Ubuntu Karmic laptop.
They both connect wirelessly to the LAN and all three computers have static IP addresses assigned.
So here's the issue. The desktop serves the laptops over the LAN with Samba file sharing, SSH, VNC and DAAP.
From the Windows 7 laptop, the connection over the LAN is fine. I generally use it to connect to the Samba shares and occasionally use it for VNCing to my Desktop's....desktop. It is fast and responsive.
From the Ubuntu laptop though, everything seems very slow. Connecting to the samba shares results in a wait of at least 30-60 seconds, even if they have only recently been accessed. Once it has connected (i.e. once the share opens up and you can see files) actually opening the files themselves is delayed too, but not to the same extent.
Also, connecting to the desktop via VNC is intolerably slow, with mouse movements being so delayed that it is almost impossible to click on anything.
SSH takes a long time to connect too (up to 30 secs) but obviously once connected it is fine. In a similar vain, FreeNX connection takes a long time to connect but once the desktop has loaded it is fine too.
I can use FreeNX instead of VNC but actually like using both for different functions. I understand VNC is slower than FreeNX but over a 100Mbps LAN connection I wouldn't expect it to be slow at all.
This laptop used to be a Windows Vista/Win7 laptop prior to being replaced with Ubuntu and it was able to connect to the server with no speed problems.

I've just installed the ubuntu 9.10. I have one problem with it. I have a home net in configuration: Windows XP on a cable, Ubuntu on a cable and Windows on wifi. When I'm surfing on the net on Ubuntu, Wifi isn't work how it should. It's very slow and I don't know what to do with it. Windows XP on a cable is OK, it works good. What happen and how can I repair it?

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

Apart from that, I must say that Ubuntu 10.04 is fantastic. Easy to use, elegantly designed and working perfectly on my PC

Lately I have been using my window's partition due to the fact that 10.04 drops my wireless signal every 5-10 minutes, but today I downloaded the new updates and that seems to have fix the issue with the dropping of the wireless connection. Now the only problem is the internet is so slow when trying to go to webpages it times out. I have opened up firefox gone to about:config and changed the necessary lines, but still dreadfully slow.

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:

It has a button next to the power to show the wireless status, on or off. If I turn the laptop on with the wireless active, it keeps flickering between on and off states, and gives me a really slow connection.It happened in 10.04 if I booted with the wireless activated, but could be fixed by resetting the wireless. Now in 10.10, it happens constantly, and I just wont stop.My laptop is a CompaQ Altec Lansing running 64 bit.

I've got a Linksys WMP54G Pci card of some kind that's being reported as a Ralink rt2500 pci, but it is very slow (50k/s cap) and has jumpy signal strength (goes between 70% and 10% every second or so, while the router is in the same room). It is just this pc, as I'm using my laptop fine right now with no such condition. I am running basically a fresh version of Slackware 12.2, so it's kernel version 2.6.27.7. I have used this with Slackware 13 and there was absolutely no issue, so I think it may be a wrong or outdated driver, but building kernel modules and updating whatever module it should be is not something that I'm very good at.

I have a linux server that has seemingly random network slow downs. This server is mainly my dvr. I'm starting to think it's a hardware problem, but that's just a gut feeling. I don't really know how to determine if it isn't.
Slow summary:SSH, HTTP, VNC incoming traffic are all affected
Outgoing traffic seems ok. I haven't tested this as much.
Rebooting mostly helps.
Stopping/starting network doesn't help
Load average is below 1.0

I use Slackware 12.1 and I have a big problem that I can't solve by myself. I'm connecting to a LAN where there are almost 20 PC connected, all with static IP.
my ip: 192.168.1.205
netmask: 255.255.255.0
gateway: 192.168.1.1
DNS server: 80.58.61.250, 80.58.61.254
I configured manually it but it doesn't works well. I set up the DHCP server on Windows 2003 so I tried to configure it with dhcp too. It gives addresses from 192.168.1.200 to 192.168.1.240 there are no PCs connected with DHCP at the moment, so my IP is only mine.
