Chili555 where are you?
I am running Ubuntu Release 10.04 (lucid), Kernel Linux 2.6.32-26-generic-pae, GNOME 2.30.2.
I have installed the ASUS USB-N13 according to your advice in previous posts, specifically, in your advice to 828688 Ben.
The dongle seems to be operating as it should. The LED does its flashing at what appears to be the correct time. Wicd also looks correct. Networks are found with good signals shown. Everything looks correct. But when I attempt to connect, "validating authentication" runs for quite some time, and eventually results in a dialogue window stating the communication failed. The required WEP password is entered in the RT2870STA.dat file, and again in the wicd window.
I have entered as much detail in the RT2870STA.dat file as I dare, and believe it to be correct.
ndiswrapper is not installed. Network Manager is uninstalled. Only wicd remains.
Any thoughts, or queries which might allow you to diagnose this predicament?
