Just share my experience with your guys...

Currently using  D-Link DIR300 Wireless G-Router, said to have 8 port (4 wire & 4 wireless), though i only use to connect PS3 & 2 laptop at one time...

The only problem that i facing during first time using is that it will regularly disconnect from PS3 without reason, then call up to D-Link Customer Service, get to know that the model need to download a patch to solve the disconnectivity issue.

So just follow his instruction, go to ftp file & download the patch into the router, so far until now the online went perfectly without disconnect from PS3 (touch wood!)...

Btw i'm using Streamxy 2.0 Mbps...

Hope that the little info can be a guidance for those who intends to buy D-Link wireless router...

Edit: btw i get NAT 2 for my PS3 and the D-Link router cost RM130..and i check in speedtest, download speed around 1.6 - 1.7 Mbps and upload speed  around 500 - 600 kbps
