Fedora Networking :: WiFi Getting Disconnected Very Frequently In F10
Oct 19, 2009
Wifi getting disconnected very frequently in Fedora 10. I am facing issues in my Toshiba satellite laptop, after a fresh install of fedora - 10. After the install, The wi fi connection is dropping off very often, and even on keeping wpa_supplicant and wifiroamd in "active" state, the connectivity needs to be established manually.

i am using broadcom wireless (4312) on my laptop with FC15 and configured it using [URL]. initially it ran great without any problem (for a week). but from yesterday, every 15 minutes or so, my wifi started getting disconnected, showing the wireless login screen . I can reconnect only by rebooting or restarting network manager service.

Im using Ubuntu netbook remix on my wife's hp mini. Ever since I switched my router out this netbook will connect to my wireless network, then show a disconnected icon, yet the internet still seems to work. I've searched around and seen that other people have had this issue but I haven't seen anything on how to resolve it.

I tuned on my netbook and my wireless signal had a red exclamation.
Wireless is enabled.
Wireless Networks shows disconnected
I don't get it. Can't seem to get it to connect? How? If I open the connection information I can see the wifi networks around me. And edit/add/delete. But when I go back to the signal and click. it just shows wireless network disconnected and no option to connect. What to do? I have restarted the computer, router, cable modem, etc. Done the updates.

I have an Asus laptop with a BCM4318 wifi chipset. result of lspsci command about wifi cards:
Code:
00:09.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) For some reason, I often get disconnected. Once it's disconnected, I cannot connect anymore and I need to reboot my laptop in order to get the connection back! I didn't have this problem when I was on Ubuntu 8.04. I checked in /var/log/syslog and I found this when the network is disconnected:

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

I'm having issues with my wired network. After about 5-10 minutes of turning on my machine, the network will drop out. Sometimes rebooting my pc or router will fix the connection, other times it will have no effect. Also, sometimes the connection will completely disconnect, other times it will appear to be connected (i.e. the network icon will indicate that there is a connection), but trying to ping a remote server or the router will fail.
This problem first showed up on Fedora 11 64, however I've just installed Fedora 13 64 and that hasn't helped. I'm using a brand new NIC (I've tried using the onboard NICs). The machine also has Windows 7 installed, which is able to connect just fine. Apart from changing NICs, the only other thing I've tried is switching from dhcp to a static IP address.

I have installed Fedora 13 and updated it. I simply cant use ssh to connect to this Fedora, not even locally. I have enabled port22 in firewall settings and nothing. Tried to disable firewall completely and nothing. I have disabled SELinux (not sure if it has something to do with this, but... ) and nothing. Entered "ALL: ALL" in /etc/hosts.allow and still nothing. Dont know what to do anymore.
Here is what happens when I try to ssh to this machine, even from it:
[flibio@surf ~]$ ssh localhost
warning: Need basic cursor movement capability, using vt100
flibio's password:
Authentication successful.
Disconnected; connection lost (Connection closed.).
Connection to localhost closed.
[flibio@surf ~]$
Looking into Services > sshd and it says "This service is dead."
So I tried:
[root@surf etc]# service sshd restart
Stopping sshd: [FAILED]
Starting sshd: : OpenSSH_5.4p1 on
: FATAL: Creating listener failed: port 22 probably already in use! .....
And still I get disconnected whenever I try to ssh to this machine from anywhere. Services says that sshd is allways dead, even restarting it but I can only restart it by doing a pkill sshd before.

Recently, I had the courage of installing Fedora 11 on my laptop while risking of trashing my Windows XP. Fortunately, the installation went fine and windows and fedora seems to be working together. But I needed to reinstall Fedora because I didn't do the partitioning right. After that the problem arises. I couldn't connect to the wlan. The first installation it was working fine. Now I can't. I select the network, enter the password and then it just says "Disconnected" or something like that then nothing else happens. So I had to reinstall it again thinking I did something wrong on the installation. But still it wasn't working. But it seems to be working when I boot from the live cd. I must have messed up my network configuration.

I upgraded to Karmic the other day and my Wireless Internet has been disconnecting every hour or so. I had the same problem on Intrepid but I managed to fix it somehow. After disconnecting, it will reconnect after a few seconds.

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

I am running FC12 64bit. Frequently the system hangs usually one app - Thunderbird. If I have Firefox up also, it seems to run fine. The light indicating disk access is on almost constantly. Is there a way to find out what process is accessing which disk? I have 4 hds installed - 2 IDE and 2 SATA. I am having a similar problem trying to do a reboot - it does not reboot within 15 minutes. I need to hit the reset button.

I'm having problems with my Internet. I just recently downloaded 10.04 (went from 8.04) and now I can't get online! I could yesterday! I don't have access to the router, but the internet works great on all my Windows computers. On my panel it show's my wireless connection bars with an exclamation mark and says disconnected. I don't know what to do! It's a Toshiba Satellite computer.
Also, I can't update anything, or install anything because I don't have direct access to the router. I know there is a lot of information about this problem already, but everything I've seen needs me to download new drivers. If you know how to do it from one computer to another I can do that. I'm just not very techy.

This morning I connected to internet, using the 'hidden network' feature of Ubuntu, like I always do. In the beginning it worked well, but after a while, while playing a game, I got disconnected. As I closed this game, I discovered that Ubuntu was asking for the WPA key (it was already filled out correctly) There were no changes made in the network while I was playing. My brother and his girlfriend can both connect using their Windows 7 laptops, so the network itself should be allright.

Is there a way to stop net access if a vpn is disconnected? I will be using a vpn for all my internet access on a specific machine, but if the connection is dropped, I don't want that box to continue to have access to the net until the vpn is re-established.

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.

I had installed Fedora 12. Initially it used to work fine. But then, every morning I start it, the system hangs after booting, I could only get a stable session after 2-3 reboots. This regularly happened and one fine morning, my system finally crashed. What could be the reason? Should I re-install F-12

The title message appears when I log in. Neither wired nor wireless network adapters show in ifconfig output. Network manager shows a simple networking disabled greyed out message. Both adapters work in live cd boot. Everything was working properly before; I'm not sure what happened.
