Mesk,
I know this thread is a few days old but just wanted to offer my opinion.
I have been using this router for over a year now...
http://www.dlink.com/products/108mbps_xtremeg.asp
pair it with the extreme wireless pci card by dlink and its a great combo. I have 4 pc's and a laptop all running the wireless and have had no problem with them at all. Ping and connection have also been very satisfactory. I live in a 2 story house that was built in '32. it has plaster walls. I have one pc downstairs in the basement. The wireless router is on the ground level floor inside our tv cabinet. the laptop is wherever and the other 3 pc's are upstairs on the second floor in the kids rooms. we all play UT4 together with me being on the basement level and them up top. No packet loss or dropping of any sort.
I recommend the setup but then... something newer and better could have came along since.
I tried DLinks newer router with the MIMO technology. It sucked. My connection strength went downhill. I returned it and went back to the above router.
Anyway, it's posted a bit late... but you never know.
