Fedora 14 - Connection to wlan is cut after about 5 minutes.

[BrightWarrior]

Hey there guys,

I'm new to this forum and Fedora in general, so I hope that you can help me out of my annoying misery.

I installed Fedora 14 yesterday via the installation DVD with 3,3 GB. Everything worked fine and when I connected to my wlan and entered the WEP key I got access to the internet. But after about 5 minutes, to connection just got cut and I was again asked for the WEP passkey. But when I entered it this time, the connection failed and I was just asked again (with the same key entered, it even got it saved from last time). As you can think, this is quite annoying, since the time I have internet is not even enough to get some updates done.

Ah, and by the way: The time I have internet it just is unbelievably slow. On my Windows partation, I don't have this problem.

I do have a small hint what might be the problem: When I was using Ubuntu, I always had a similar problem, but it did not even connect to my wlan once. The solution was to blacklist some driver, but since I don't know if this might be the problem on Fedora too and if the drivers are the same as on Ubuntu and since I really have no idea about the syntax of the terminal here, I was not daring to try this out.

Can you please help me?

Greeting

If it's your wireless router, try changing the channel. No promises, but it's an easy and harmless thing to try.

When that happens, try deleting all existing connections in NetworkManager (right-click the panel icon, Edit Connections, Wireless, Delete), and try connecting again. Try WPA encryption. It's stronger anyway.

Sometimes, there are alternative drivers and methods for a particular wireless chipset. You should take a moment to identify the chipset and the driver its now using. Maybe someone will recognize it and know something to try. If it's using the PCI bus, then the following may identify the chipset. Open a terminal, run the following command, and paste the lines related to the Network Controller or Wireless LAN Controller in your next post...

lspci -k

If it's using the Universal Serial Bus, then this might provide some useful information...

This, too, for other modules that may be relevant...

Sorry for the long wait, I have been quite busy because of my studies and did not really get the chance to look this up. But now I finally got some time. Sorry .

The problem also has solved itself in a way. Fedora is running for about 30 min. now and the connection is not cut yet. Though it can not really be working right, because my internet is way slower than on Windows and also the software update function is not working right. It is hanging at "checking for currently used applications" (translated by me, my Fedora is German) and does not go further. Does anyone now advice?

My parents would kill me if I'd try something like this^^. And since I'm not really an expert about networks and stuff, I really better do not try this^^.

Can anyone read something out of this that might help me? Please, I really want to have a proper running Fedora. If you need any further information, please ask.

I had this happen (or at least something similar) on 2 of my Fedora 14 laptops, but it wasn't happening in Windows. Ultimately the solution for me was to change the channel width on my wireless router. It was set to Auto (20MHz or 40MHz). I set it to 20MHz only and it seemed to fix both the speed and disconnect issues.
