what wireless card does the PS3 have in it?

Does it support Wireless-N ?

If it supports wireless N then go for a Linksys that supports it. The signal strength and speed are much better than Wireless-G

But if PS3 doesnt support it, its pointless so just get a Linksys WAG54G (ADSL) or WRT54G (NTL/Telewest/Virgin) or whatever the current models are

Netgear are dump
