off & on problem wireless

Postby jdashbaugh on Tue Mar 12, 2013 12:31 pm

My office computer downstairs connects wirelessly to my router. The problem is that it just will not stay connected (KDE desktop). It connects at first boot, then after about 5 minutes disconnects and refuses to reconnect and acts as though the network password is incorrect. I had a similar problem on another computer in the house and the problem was caused by having more than one network manager installed. Sure enough there were multiple managers but after removing the ones I found the problem remains and now only the KDE desktop connects for just a short while and disconnects. Gnome and LXDE will not connect at all. How would I go about checking to see if there is a network manager that I missed still installed. I need the wireless connection on this computer as it also connects to a network printer.

Thanks in advance

The kde desktop switched to the netman (used with Gnome) desktop instead of their own GUI version

--if it is network manager, you can stop and restart to enable networking, it should be on the system taskbar, usually on the right hand side

There are a lot of command line (terminal: bash) commands available to check the network status, as well as some GUI network applications..

--a bigger guide, but includes a network section

Code: Select all
ifconfig
--standard any network card
iwlist
--wireless
ping
--check an address
netstat
--netbios names instead of IP address

Please run inxi -N in terminal and post the output, then we'll know what wifi card your computer has. What could also be useful is the output of rfkill list.
