You should post your question in the Compaq/HP forum, you will get several replies pretty quick. I am not familiar with a BT Voyager 2100 wireless ADSL. Is it 802.11b? Do you have WEP or WAP turned on? Have you tried to "refresh network list" in the wireless network connection window? You can also try installing netstumbler to locate all available networks - you may have other access points from the neighbors causing interferance and may have to set your access point to a different channel. Try driving around down with the tablet and see if it will pick up any access point at all. If the green light is flashing, the wireless card is turned on, but you can try turning it off and back on again via the Q menu.
