Linda, you could try uninstalling AVG but before you do that, make sure you download a different antivirus proggie (I use Avira but there are numerous others free out there), ready to install it AFTER uninstalling AVG. After D/L a new proggie, disconnect from the internet by unplugging the ethernet cable to the Livebox and uninstall AVG from the Add/ Remove Programs tab in Control Panel. After uninstalling it, reboot the computer (remember to keep it OFF THE INTERNET at this stage. ) Then install the new antivirus prog and check all your firewall settings etc to ensure that the new prog is allowed to access updates etc, Then reconnect to the internet.
Try your wireless adapter again.
New cable should be with you tomorrow hopefully???
If the Inventel wireless card just won't work in the end, I have another plan up my sleeve........but lets see how it goes!!
