Kubuntu Wireless Issue

SpiderIRE · 01-31-2010, 02:03 PM

Hi Everyone.

I installed Kubuntu 9.10 this morning and haven't been able to get my wireless working properly. I can connect to my network (WEP 128bit key) and acquire an IP address without any problems. But as soon as it connects it stops talking to the router (about 4 pings after it connects). The pings then change from a reply to saying "Destination host unreachable", even though it works fine on the Windows box I'm sending this from.

I'm using an external USB dongle (D Link DWL-G122) and the drivers listed are rt73usb. The output from iwconfig is:

Code:

lo        no wireless extensions.

eth0      no wireless extensions.

wmaster0  no wireless extensions.

Does anyone have any ideas?

Thanks!

The only thing I see, is your receive signal level is -68 dBm. That looks low, you can try moving the system closer to the wireless access point, and see if the receive level improves ( it should ) and see if it will then work.

If it does work with a stonger Rx level, you may need to 1. move the access point closer, 2. use the system closer to the access point.

If that doesn't help, there is nothing I can see in what you posted. My wireless Rx level runs about -50 dBm, as a comparison.
