NAT Error (HAVE READ OTHER THREADS)

[gooner]

Hello all,

I have the dreaded NAT error after changing from wireless to LAN, all settings have been optimised previously and everything was working well but since dropping the wireless i have had this problem.

Speeds have dropped from around 250KB/s to 100KB/s, at best.

I have a buffalo WMR-G54 ADSL router, 2MB Broadband connection. I am using Zonealarm configured correctly, windows firewall is turned off, port forwarding is correctly configured, have tried numerous ports but to no avail and the network itself is working fine.

Any ideas would be much appreciated, thanks
