wireless distance cut in half?


I have installed kubuntu 8.10 on the laptop my wife uses, a Toshiba Satellite A105-S2071. Using Windows, the wireless would reach from one end of the house to the other. But now the wireless starts cutting out intermittently and I think it has something to do with the distance.... but Im not sure.

So the network manager is KNetworkManager.

Under System->Hardware Drivers I have the following item listed:
Support for Atheros 802.11 wireless LAN card.

Other than that I really don't know what other info to provide or how to get the info as I am relatively new to linux. I need to get this wireless working correctly.

Any help would be appreciated.

Also, the clock is in military format; how can I change that.

Or your neighbor just got wireless and they are using the same channel or the channel next to the one you are using..

iwlist ath0 scan - to check for other nearby access points.


It could be related to incorrect antenna settings since hte madwifi driver does NOT automatically detect this setting..
Take a look at UserDocs/AntennaDiversity. You'll want to disable transmit diversity if you only have one antenna connected.



The other item in their FAQ suggests if you are having performance issue s that you get the latest version of the madwifi driver before asking questions through the support channels. http://madwifi-project.org/wiki/UserDocs/GettingMadwifi

I had a similar problem with Ubuntu on my Compaq Presario C751NR. Oddly though, when I put Mandriva on it, I got an ENORMOUS boost in distance compared to my friends using Windows PCs. Try making sure all of your software is up to date, and try using the software "wifi-radar" to scan for and connect to wireless networks. It seems to work better than the built-in KDE network manager.
