hopefully it helps...

I'm not sure why u use 192.168.2.1 for ur gateway (maybe because im using D-Link and my gateway is 192.168.1.1 and before this im using 192.168.0.1) but what i couldn't understand is ur DNS

Try this :

Streamyx DNS :
PRIMARY : 202.188.0.133
SECONDARY : 202.188.1.5

OpenDNS (currently using since i don't trust Slowmyx/Snailmyx)
PRIMARY : 208.67.222.222
SECONDARY : 208.67.220.220

don't forget to chance the DNS setting at ur router...
Hope its fix ur problem, if not try set DNS to auto

*EDIT : Stupid typo...and another typo...haihh...*

Friend, im totally lost and had no more idea how to solve ur problem since i don't have the same router as your but why don't you try emailing Belkin and tell them in complete details whats your problem and what u have done to fix it. Send them altogether with screen shot might help. At least now i know that if i want to buy replacement for my current router i won't buy belkin...
