Xbox 360 can't find router?

[British_Command]

I have had an pretty basic low end router for quite some time now and wireless has never been a problem but recently it started failing to connect or even find the network, only sometimes my connection would show up.

Anyways I decided to go and buy some belkin router assuming it would be better... and it is, but I'm still having the same problem, sometimes I can connect for a few mins and it'll then dsconnect. Sometimes it won't find the network but it'll find others and other times it'll fail on DNS? I've connected through wired connection and it basically does the same thing? but it'll find the network and fail on DNS! despite having other devices ( computers) that connect fine wireless.

Any possible suggestions?!

Thanks,
BT

BUMP, but also whenever I try and connect via 360 I get this security log message :

kernel: Intrusion -> IN=ppp_0_38_1 OUT= MAC= SRC=218.61.200.27 DST=80.42.135.47 LEN=40 TOS=0x00 PREC=0x00 TTL=108 ID=256 PROTO=TCP SPT=6000 DPT=2967 WINDOW=16384 RES=0x00 SYN URGP=0

any help? it varies as in the DPT (destination port) source etc.
