"But it disconnects, reconnects to "another" network and it doesn't work anymore."
Did you try another RF channel? Try 1, 6 and that last one.
I've got a problem with the configuration of my Wireless-LAN connection. The PC with PCI WLAN card works fine (internet, networking). But I just installed an Asus 103-b PCMCIA card in my notebook. With MAC adress filtering and WEP (128 Bits) there is no internet connection, even though the laptop is connected to the router (at a very good speed: 11Mb/s). Without MAC filtering, with WEP, the internet sometimes works. But it disconnects, reconnects to "another" network and it doesn't work anymore. Same with no security at all.

Thanks a lot people, Claus
