I have had another three fruitless hours at this to no avail.
I have reset the thouter and used the setup wizard on Netgear's advice.
I have checked everything I can and get no further.
Options attempted.
1. Router has no longon details
2. Router has logon details.
3. Use the IE connections dialogue (dials 0 800 555-5555 - I think this is a dummy number).
4. Never diala connection - this is the worst option - nothing happens at all.
5. Turn off NAT
6. Turm on DMZ for ports 1 65k on TCP/UDP.
7. Turn off Stateful Packet Interface.
8. Respond to ping - getting desperate now.
All done using both logon with router and no logon with router.
Screen names with and without @aol.com
Always the same. I get AOL9 starting, go to Sign ON and get as far as Initialising DSL Modem. Then it always fails with error AC-3100 and various guesses at what was wrong (I tried them all!)
Obviously I will get back to Netgear, but please, Help!!!
