OpenSUSE Wireless :: Strange WiFi Behavior Breaks Connection Repeatedly

May 30, 2011

I have recently upgraded to 11.4 and also had to renew an AP (HP ProCurve 10ag). This was several years old but replaced an identical model which had been working well until recently. I thought it would be appropriate to flash newer firmware as the device four releases behind the times. The access point serves partner's XP laptop and my openSUSE 11.4 laptop and after flashing the firmware both machines would make a connection and then break and remake, to the extent that the openSUSE machine became unusable. I thought it was an encryption problem and spent hours changing the AP and Client setups to no avail

After reading a thread here I checked out dmesg and this is what I found:-
[78.639247] wlan0: authenticate with 00:1d:b3:4b:ae:14 (try 1)
[78.640804] wlan0: authenticated
[78.642507] wlan0: associate with 00:1d:b3:4b:ae:14 (try 1)

[78.652283] cfg80211: Calling CRDA for country: DE

This went on and on.

Ubuntu Networking :: Intermittent Internet On Wireless/wifi - 10.10 Disconnects Repeatedly?

Dec 31, 2010

I just upgraded to Ubuntu 10.10 because I was facing internet problems with previous Ubuntu 9.04 after I upgraded it with downloaded software. And now, 10.10 connects to wireless, but shows web-page some-times and repeatedly disconnects. Earlier it wasn't reaching Internet at all. Some of the topics here helped a lot. But this intermittent internet seems not going anywhere. Wired Internet connects easily though.

I've tried :-

-disabling ipv6..... first in Firefox, then in Kernel also
-Setting DNS.....System> Preferences> Network Connections
-setting static Ip

The system still gives trouble.

My system is Asus UL20A.
Wireless:-Atheros AR9285

OpenSUSE Wireless :: WiFi Connection Dropping At Irregular Intervals

Jan 5, 2010

In summary, I am using openSUSE 11.2 x64 on an Acer laptop with a wireless AR928X card. I can connect to my WEP-secured network when I boot up. After some time (it might be minutes, it might be hours), I am prompted for my WEP password again. This never works, despite being the one which gets me on-line at start-up!. The only solution is a reboot. The problem is intermittent and doesn't seem to depend on my on-line activity. I have tried the following with the same result:
KNetworkManager
Traditional using IFUP
Enabling / disabling IPv6 support

I tried installing the compat-wireless package through YaST and then managed to get no internet connection at all. Went back to KNetworkManager and things "worked" again until I was prompted for the WEP code. I have openSUSE 11.2 x64 working on my office laptop without problem and can connect to my home network without any problem. My issues are with my personal laptop. I have reached the stage of booting into Windows 7 as my default option so that I can access the internet reliably. What I can do to diagnose and repair the problem - could it be that the card is going into powersave mode? If so, how do I stop that happening? I'd prefer to be on openSUSE but need to be able to rely on the internet.

OpenSUSE Wireless :: Increasing Multicast Rate For WiFi Connection?

Jun 19, 2010

I have two laptops. First one is connected to my ISP via Ethernet connection. At the same time it serves as a wireless router for the second laptop (ad-hoc connection). Multicast routing is managed by igmpproxy. Everything works fine, except that multicast traffic rate on the second computer is very low (1 MBit/s), its too slow for watching television.

After some searching I found that this multicast rate is always minimal one for certain type of WiFi connection (802.11bg in my case) https://lists.ath9k.org/pipermail/at...il/003393.html. For some WiFi kernel modules its possible to set multicast rate by setting appropriate module options. But its not the case with ath9k.

WLAN configuration on the "router" laptop:

Code:
iwconfig wlan0 mode ad-hoc
iwconfig wlan0 key 1111111111
iwconfig wlan0 channel auto
iwconfig wlan0 rate 11M
iwconfig wlan0 essid WHATEVER

how to increase multicast rate on the second computer?

OpenSUSE Wireless :: Wifi Connection Fails After The Recent Update?

Jul 8, 2010

Recently I updated my openSUSE 11.2 and I'm not too sure what all were the recent updates but I suspect networkmanager also got updated. After I restarted my machine, my laptop fails to connect to the wireless access point. I tried both in gnome as well as KDE but the same error. This is the log I found in my /var/log/NetworkManager which I believe should give some pointers.

Code:
Jul 8 15:08:42 AshSuse1520 NetworkManager: <info> Activation (wlan0) starting connection 'Buckeye Plaza'
Jul 8 15:08:42 AshSuse1520 NetworkManager: <info> (wlan0): device state change: 3 -> 4 (reason 0)
Jul 8 15:08:42 AshSuse1520 NetworkManager: <info> Activation (wlan0) Stage 1 of 5 (Device Prepare) scheduled...

[Code]....

I did a search of this error in google and all I got were few results which complained about bugs in some debian distro.

My wireless card works fine and so does the access point I try to connect to since my Ubuntu installation is able to connect fine as well as my windows Xp.

OpenSUSE Wireless :: Very Slow Start Of Knetworkmanager And Wifi Connection?

Dec 2, 2010

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.

Networking :: Strange Martian Behavior When Using Switch Vs Hub?

May 21, 2010

I have an old PC running an older version of linux with two network cards serving as my firewall router. The network cards are netgear 310tx cards. Noticed traffic was not getting routed at times. Figured my switch was going bad, so I hooked up an old hub to keep keys systems communicating while I get a new switch. No problems with hub, but only has 5 ports.

Get new switch (different make/model from old one), install, a couple of my systems have connectivity problems, but others do not. Thinking it was a bad switch, returned it, got a new one just like my old one (which I thought was going bad, but worked for several years). Hook it up, paying attention to my firewall console and notice martian header messages. Network traffic not getting routed at all. The interface for connected to LAN was slow to get started (my firewall can communicate to the Internet, but LAN communication was hosed).

System would "hang" spitting out martian header messages until I disconnected LAN cable. Thinking network card may be bad, replaced it with another version of the same type. Same problems: martian header messages and traffic not getting routed.

HOWEVER, if I remove the switch and use my old hub, no problems. Networking appears to work for all systems connected to hub. Since I and my wife work from home, I'm using the hub right now (with non-essential systems not connected due to limited ports). I can only do any real experimentation at night.

I have no idea why things would work differently between using a hub vs a switch. Could something have gone awry with the linux kernel (2.4.20-46.7)?

Ubuntu Networking :: Strange Behavior With Pings From Desktop?

Mar 9, 2011

I've been trying to use MySQL in Ubuntu but I've been having some connection issues and in trying to troubleshoot that, I observed this strange behavior with pings in Ubuntu Desktops inside our network.

- All Ubuntu Servers we have (10.10 and 8.04) behave as expected
- All Windows machines behave as expected
- All 5 Ubuntu Desktops we have, (10.10 and 9.10) exhibit the following unexpected behavior:

If they have a local ip addresses and are connected within the internal network, either to a switch or directly to a router, pings take much longer to be sent. It's not a higher lag, it's the time between each ping that increases. I have to wait for around 5 seconds for each ping, but the time in the ping reply is less than 100ms, also they're all in order so I assume it's the system delaying the sending of each ping.

If I plug a USB 3G modem directly then it works as expected again (~1 sec between each ping sent). Is this an intended feature, that depends on the network environment, or is this something I should look into more closely?

Networking :: Can Ping But Can't Wget / Strange Network Behavior

Apr 28, 2011

I have a small ARM machine running an Arch linux variant, PlugApps. It was set up and working fine at my home, with a standard networking setup -- cable modem and router. I could do pretty much anything I needed to access the net fine.This machine is a remote monitoring system for another location. I shipped it to that location and am now trying to get it set up using another set of hands on site. There it is on the network behind a dsl modem and a router. I forwarded ports from the dsl modem to the router and from the router to the ARM computer.

In both cases the ARM machine is/was configured to use dhcp.So here's the deal:I can ssh into the ARM machine just fine.I can ping hosts on the wan fine (eg: stanford.edu).BUT:wget fails for not being able to resolve a valid address (eg: http://checkip.dyndns.org)the PlugApps package management system (pacman) cannot resolve the repository address the openntp time sync isn't working On the new network, I am able to connect to another client windows PC which has the same associated network info (Bcast address, Mask, etc. - comparing windows "ipconfig" vs linux "ifconfig" outputs) but which can resolve addresses for web browsing, etc.What am I missing? If it can resolve addresses for pings, why can't it work for other address requests? If I can ssh interact with it, why can't it connect to the net for other purposes?

OpenSUSE Install :: Dual Boot Breaks Wireless?

Mar 16, 2011

I'm a regular OpenSuse user, but recently I had to download Windows7 on my computer for work. Everything was fine for a while, but now when I switch to windows, the wireless doesn't work sometimes (sometimes it works just fine). When this happens wireless is broken on the Linux side as well. The only way I know to fix it is to hard wire the laptop when booted into windows, and then everything is back to normal. It's really starting to tick me off and I have no idea what may be causing it. I didn't even know the two partitions can effect each other.

Ubuntu Networking :: Wifi - Set Up The Wireless Connection Using WPA But Could Not Connect

Mar 19, 2010

Using an old (5 year) laptop with XP loaded I installed wubi to save altering partitions etc. It all downloaded fine and connected to the internet by wire. I set up the wireless connection using WPA but could not connect. The wirelsss card does see my network and others. After lurking around the forum and trying various things I found that I could connect without encryption. The more I read the more I became confused.
Anyway what I could glean about my Wireless Card it is a Intersil Prism2 mini usb adapter - but also shows up as an Acer ?? Warplink 802.11.

Using lshw I found this reference to wireless

I became even more confused and got a bit lost using the various codes in the terminal and looking up things about drivers etc but would like to persist.

Ubuntu Networking :: Losing Wired Connection Repeatedly?

Nov 1, 2010

I did a clean install of 10.10 just under a week ago and something is really wrong with my wired connection. I keep loosing all connectivity and have to connect again from the panel app. After that, every thing works again for about 30 to 60 seconds and the the connection goes again. No lost connection notification pop up or anything like that, but i cannot browse the web or download upgrades while the connection is gone.

Then the really weird part. Sometimes my connection works just fine. On some boots everything is fine for a long time (hours?) but then the problem comes back. My network card is an Intel 82567LF-2 and it uses the e1000e kernel module. I dual boot to Windows Server 2008 R2 and there I have full connectivity all the time.

Ubuntu Networking :: 9.10 - Wireless Asking For WPA Key Repeatedly

Mar 16, 2010

I'm a new Ubuntu user! I've just installed Ubuntu 9.10, straight from the homepage. All went fine, everything appears to be running smoothly.. but I can't get the wireless working! All it does is ask for the WPA/WPA2-Personal key repeatedly. I know I've got the code right, as I've typed it whilst "Show Characters" is on multiple times. Every time I enter it, the networking icon looks as though it's working, and then after a moment it'll ask me again.

Ubuntu Networking :: Wired Network Connection Lowers Link Speed Repeatedly

Apr 1, 2011

I believe I'm running Kubuntu 10.04, but don't quote me on that. Here's the version string from dmesg. Linux version 2.6.32-31-generic (buildd@crested) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #60-Ubuntu SMP Thu Mar 17 22:15:39 UTC 2011 (Ubuntu 2.6.32-31.60-generic 2.6.32.32+drm33.14 I have an emergent problem with my wired ethernet resetting the connection on a frequent basis. When it resets it re-negotiates the link speed and I often end up with a 10Mb/s link and on some occasions a 100Mb/s. The configured speed for the link is 1000Mb/s full duplex using a preup ethtool command. I do not use NetworkManager but have the interface configured in /etc/network/interfaces.

Ubuntu Networking :: Wireless No Longer Connecting And Repeatedly Asking For WEP Key

Jul 28, 2010

I downloaded the latest version of Ubuntu yesterday (10.04 LTS) for the first time and it worked like a treat, with the Internet conencting immediately without any problems. However, this morning I turned on my laptop and despite seemingly connecting to the network, Ubuntu won't conenct to the Internet. It is also repeatedly asking for me to re-input the WEP Key despite it being correct and always automatically inputted.

Ubuntu Networking :: Wireless Repeatedly Drops After 10.10 Upgrade - Broadcom 4309

Oct 23, 2010

My wireless connection ran without issue when I ran Ubuntu 9.x on a windows dual boot loader. Liking Ubuntu, I wiped the system and installed a 10.10 with no dual boot. After the upgrade, my wireless connection is no longer reliable.

Wireless seems to stay connected when traffic volumes are low. As soon as any significant traffic is generated such as a download, torrent or video stream, the network disconnects. Disabling and re-enabling the connection at the GUI recovers the connection. Disconnect can be generated on demand.

If I can somehow roll back to the 9.x network setup I was running. Unclear to me (n00b) if the windows dual boot was impacting that setup or not.

Ubuntu Networking :: Wireless Repeatedly Stops Working On HP Pavilion/Intel 4965AG/Karmic

Feb 9, 2010

My wireless LAN connection on this machine occasionally stops working. The network traffic bar shows periodic very small transmissions but the failure of all network dependent applications (Firefox, package manager, etc.) indicates to me that the machine is no longer talking to the net. I can fix it by reselecting my home network in nm-applet from the drop-down list. This causes the machine to disconect, reconnect and all is well for some random period of time thereafter. Here's some data:I'm running an HP Pavillion laptop.

Code:

~$ lspci | grep Wireless
02:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)

Code:

~$ lsmod | grep iwl
iwlagn 124768 0
iwlcore 134820 1 iwlagn
mac80211 243496 2 iwlagn,iwlcore

[code]....

I don't know if this is related or not, but a couple of months ago I unsuccessfully attempted to share a hotel's wired Internet connection over my wireless card. I may have hosed some settings or it could be unrelated.The "unknown interface" portion of the restart attempt is interesting but I don't know enough to fix it.
