Sorry to come back after all this time but I struggled to obtain info asked for. However my neighbour's son sorted out the security for me when I asked his advice ,just for the info!
After acouple of weeks I now have problems getting onto the internet and I do not know if there is a connection. When I turn on PC everything powers up but my Netgear does not activate to internet but says "acquiring network address"(client IP address). This can take several minutes and when it finally finds it a sign comes up to say "restricted or no connection". This may clear itself but normally I turn off wireless then back on and this sorts it normally within a couple of minutes.
This is only just happening and I have had no such problems previously. My netgear came from Telewest, my PC is a Dell and I use Windows XP home edition. Can anyone point me in the direction to cure this problem.
