I have the same problem on my Dell Inspiron 9400 with a Intel® PRO/Wireless 3945ABG wireless card. The connection drops when using Google Maps, Youtube or other big downloads.
Also tested the linux-backports-modules-wireless-lucid-generic packages, but no luck there. Never had any problems on Ubuntu 9.10 or 9.04 with this laptop. Also tested with Win XP on this laptop. No problems so it's not the router or laptop.
