There seems to be a problem with the Intel(R)PRO/wireless 3945ABG Network connection, on my Amilo Pi 2515. Works fine when connected with ethernet cable. Otherwise, it shows no networks available (even though my macbook picks up wireless signal just fine.) Do I need to download a new driver? (as someone's suggested) if so, any ideas for one compatible with a new D-link router DSL-2640 model?
