Hello everyone!

I have a problem with my LogicPro Linux compatible wireless adapter that uses the RTL8187B chipset. Basically, when I connect, it stays connected for a few minutes, then it drops. I then reconnect the first time, which worked OK, then it dropped. This happens again and again, which can be a nuisance when downloading updates or other distros. After a few of these cycles, it refuses to connect unless I unplug and replug my dongle. Here is some information:

PC model: Fujitsu-Siemens Scenic P320.

Lsusb results: Bus 001 Device 005: ID 0bda:8189 Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter

Any help will be appreciated. :KS

By the way, the router uses WPA/WPA2 encryption.
