Ubuntu Networking :: Rt2800 Wireless Disconnecting Frequently

Apr 23, 2010

My wireless card disconnects frequently and sometimes it won't even connect at all. I've googled the card and the driver and it looks like others are having similar issues as well. [url]-[url]

My lspci | grep -i network is as follows

Code:

Under iwconfig, it's identified as wlan0, and I'm running kernel x86_64 2.6.32.9

Debian Configuration :: USB Wifi Adapter Frequently Disconnecting

May 20, 2015

Using a USB ISO, I recently installed Debian 8.0 Jessie (64-bit, Xfce DE) to a new computer. I usually lose my Wifi connection after 1-3 minutes when donwloading/uploading at around max. speed 4 Mbps/512 kbps. Sometimes it will last 15+ minutes.

When lightly browsing it can usually stay connected for 15-30 minutes. I have to disable and enable Wifi using NetworkManager to connect again. If I remember correctly, there were problems with the Wifi connection even during the installation of Debian.

This Wifi USB adapter works fine on my old computer with Debian 7.7 (32-bit). No problems with the Wifi connection yesterday on my old computer during 10+ hours of activity.

This Wifi adapter also works fine on this new computer when I boot from a live USB (Rescatux 0.30.2) downloading and uploading at max. speed for 1+ hour.

I already tried some suggestions I found online, but they didn't work:

* changing Wifi channels between 1, 6, 11 in my router settings
* changing WPA-WPA2 to WPA2 in my router settings
* ignore IPv6 in NetworkManager
* change probe_wait_ms from 500 ms to higher value by adding Code: Select alloptions mac80211  probe_wait_ms=1000 or Code: Select alloptions mac80211  probe_wait_ms=3000 to /etc/modprobe.d/mac80211.conf and rebooting
* disable Power Management for Wifi adapter (not supported)
* ...

I can also post the output of commands from Rescatux or my old computer if needed.

Output of commands on Debian 8.0 64-bit (I edited out some info, MAC, ...; not sure if that is important):

Code: Select alluname -a

Linux d8lnx 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-2 (2015-04-13) x86_64 GNU/Linux

Ubuntu Networking :: Wireless Keeps Disconnecting On 10.10?

Nov 8, 2010

I have always had trouble in the past getting wireless adapters and what not to start working on Ubuntu but with each 6-month upgrade most problems are fixed while new ones are made. Since Ubuntu 10.10 just came out I thought I'd give it a go and test it with my hardware.

Before 10.10 Ubuntu could not connect with my wireless device and I had to do many things with gedit and such to get it working. After I have upgraded to 10.10 Ubuntu now recognizes my wireless device and network and I can search the web...but wait here it comes.

Literally minutes after a fresh install and first connection to my network my wireless signal will drop and prompt me to reconnect. Of course the first thing comes to mind I reconnect which doesn't work so I unplug the device and replug it making it works...Two minutes later my connection drops again and so I so reboot, and if you really want to know what happens next just restart this paragraph.

Things you need to know Operating System - Ubuntu 10.10 64-Bit Wireless Adapter - Hawking HWUN3 Hi-Gain Wireless-N Network USB Adapter Router - Apple Airport (99% sure it has all updates)

Ubuntu Networking :: Wireless Disconnecting Every Few Minutes?

Jan 16, 2010

I have a Toshiba Satellite M55-S325 (as it came from the factory, no mods), a Linksys WRT54G router, and Ubuntu 9.10/Karmic with all updates. I've had issues since I upgraded from 9.04/Jaunty to 9.10/Karmic. It did work for awhile (I think a few days), but then it suddenly just couldn't find our wireless network. I reformatted (with 9.10) thinking it had just been a bad install - now I can connect to our network, but it throws me off every two minutes. My roommate (Dell laptop, Vista) has no problems with the internet, and I've visited a friend (in another state) and used her wireless internet without issues (though I couldn't tell you which router they were using). I've gone into our router's settings (with both my laptop and my roommate's) to reset the router or change the security settings, but with no real progress.

Here is my ifconfig results:

Code:
eth0 Link encap:Ethernet HWaddr 00:0f:b0:87:b3:80
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

Ubuntu Networking :: Wireless Disconnecting In 9.10x64

Feb 13, 2010

I recently did a clean install on my ASPIRE 5490G laptop with 9.10x64 and am having some odd problems with wireless.

The wireless will suddenly drop and ask me for re-authentication of the encryption key which I put in. Then it will ask me again. It will then refuse to connect to the router.

If I hit cancel then on the notification area the nm-applet will not have the router listed in the wireless networks .

If I kill the nm-applet and restart it with ALT-F2 and run nm-applet --sm-disable it still does not show the networks available.

I know it is not the router as my flatmate who I share with uses a laptop with Windows 7 and they have no problems.

Ubuntu Networking :: Wireless Not Working In 10.04 - Disconnecting Again And Again

Jun 1, 2010

I installed ubuntu 10.04 a few days ago. And I am running into a few problems wherein my wireless network disconnects and prompts me again for password.

Even when I re-enter it (correctly of course) I cannot reconnect and I have to do a system restart. After the restart, the wireless stays connected but disconnects again after a while and I find myself stuck in this loop.

I do not know if the following is any help, but below I am producing the output of lspci command and a few log messages that I think maybe related to this problem

Here is the output of lspci command

And here are some messages that show up quite often in daemon.log

Ubuntu Networking :: Constant Wireless Disconnecting With Intel Based Card

May 2, 2010

This is a fresh install of Ubuntu 10.04 on a Dell XPS M1530. I'm getting very frequent disconnects to my wireless network, despite good signal. I have wicd and nm-applet running side by side, wicd doesn't work by itself and nm-applet won't get a new IP after reassociating with the AP.

Wireless connection is steady in Windows 7, so I'm guessing it's a problem with the driver.

Wifi card: 0b:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

Driver:

Code:
[ 22.889588] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 2.6.32-21-generic-ks

Ubuntu Networking :: Wireless Internet Drops Frequently With Realtek Card On Kubuntu 10.04?

Feb 11, 2011

I'm using Kubuntu 10.04.2 LTS on a Bangho laptop. Kernel 2.6.32-28-generic i686. My card is: Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter iwconfig wlan0 gives me:

Code:
wlan0 IEEE 802.11bg ESSID:"Default_WLAN"
Mode:Managed Frequency:2.442 GHz Access Point: 00:06:4F:8D:B9:AF
Bit Rate=1 Mb/s Tx-Power=20 dBm
Retry long limit:7 RTS thr: off Fragment thr: off

[Code]...

Usually when this happens, for 10 or 20 seconds it appears to be connected (i.e. the heart symbol is there) but I can't ping google or my router, then it "realizes" it's disconnected. It takes one or two attempts to reconnect successfully by pressing the "active" button. Meanwhile throughout the disconnections and re-connections the signal is very strong (98%).

I had the same problem with my old access point, at first I thought it was the cheap/old hardware, so now I bought an "ENCORE ENDSL-A2+WIGX2 | ADSL 2+ Modem with 4 Port Wireless Router". The problem persists only with a stronger signal.

Ubuntu Networking :: Blinking/Flashing LED When 10.10 Uses RT2800 Instead Of RT3090?

Jan 8, 2011

Just posting this so others can find the solution more easily than I did.My HP ProBook 4520s had a blinking/flashing wireless indicator LED and the connection was unstable. The solution was to blacklist the rt2800pci drivers. This leaves the rt2860sta drivers, which work fine for me (so far). The device is actually a RaLink RT3090 and apparently they release drivers on their web site, but I did not want to go through the trouble of building it and did not find it packaged for 10.10.To try this fix, open up the blacklist file.

Code:
gksudo gedit /etc/modprobe.d/blacklist.conf
And add this line at the end...

General :: Keeps Disconnecting From Wireless Network?

Sep 12, 2011

I'm running Arch Linux on an Acer laptop and my wirless connection doesn't stay up. After a while it disconnects, and when I try to reconnect I get stuck with a "Waiting for authorization" message. I have to retry several times before getting the connection stay up for few minutes. This happens with both networkmanager and wicd. The strange thing is that the iMac that sits next to the laptop connects fine, and when I use my laptop within the university wireless network it works normally.

EDIT: I've tried to connect manually following the steps

iwlist wlan0 scan
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf
dhcpcd wlan0

Ubuntu Networking :: Wifi Keeps Disconnecting ?

Mar 9, 2010

Wifi seems to disconnect fairly requently, sometimes reconnecting automatically and sometimes requiring me to re-enter the wep password.

I would like to make it so it stays connected.

The router is not very close, but I think it's close enough. I even moved it closer. Other devices (such as my N900 mobile phone) hold the connection without issue.

One complication is that there are several devices all with the same SSID, though there should be one which is clearly stonger.

Details below.

1 ) Machine Brand and Model (PC/Laptop):

Ubuntu Networking :: Wifi Keep Disconnecting In 10.04?

I never had this problem with Ubuntu before and I am now confused. This is a clean install and I have not change anything about my AP so don't why this is happening.

Ubuntu Networking :: ZTE MF637 Keeps Disconnecting After A While?

Aug 13, 2010

I have recently purchased a cellular usb modem, a ZTE MF637. To my surprise and pleasure the device worked (almost) out of the box (almost, because I had to supply a user name and password to the wireless broadband connection properties).

Anyway, the problem is, that the connection work fine, but only for 20 minutes or so (I did not actually measure it), then I experience 0 network activity, and shortly after that the connection drops, and the device is no longer recognized as wireless broadband.

What I do is remove the device, replug it, and after a minute it reconnects. until the next drop.

I'm using Lucid on an Asus eee 1101HA.

Oh, one more thing, in lsusb, the device is listed as MF636, but the box reads MF637. I don't know if it matters, but there it is.

Ubuntu Networking :: How To Resume SSH Session After Disconnecting

Mar 7, 2010

I'm currently using putty on my laptop to control my headless server (both Ubuntu 8.04.) I'm running an rsync job that ran all night long and still going all day today so far. I need to restart my laptop, but if I do, I'll break the SSH connection. If I SSH back in, I won't see the same thing (rsync is showing me each file it's copying) that I'm seeing now. (At least I think that's true. Please correct me if I'm wrong.)

So I guess my questions are..Is there some way to restore my SSH session when reconnecting? (So I can resume seeing which file is being copied and - more importantly - when the rsync job (finally) finishes?If not, how else can I know when the rsync job finishes?

Ubuntu Networking :: Internet - Router Disconnecting ?

Feb 14, 2011

My router is a Netgear router with Comcast, and after going on Ubuntu for a couple hours just doing normal things, the Internet disconnects. Then I have to restart my computer and start everything over again. I check the router and everything seems to be fine, I even unplug everything on the router first (like I am instructed to do so if this sort of thing happens) to make sure that's not what is causing the problem. It has to be the Ubuntu system.

Ubuntu Networking :: Can't Reconnect To Internet After Disconnecting

Aug 16, 2011

Here is my problem:

I can reconnect to internet after disconnecting (this happens every 3-4 hours) only if I manually poke out and in ethernet cable to network adapter or reboot ubuntu. Even restarting network-manager not helps. My provider provides internet over pppoe. I have "DSL-connection 1" item in network managers gui menu. And that item disappears after disconnection.

pppd runs with following arguments: lcp-echo-failure 3 lcp-echo-interval 20 So where can I change this parameters, where is that configuration file?
