Guys, I just picked up a DAP 1522 to server wireless to my house. I have a Buffalo WHR-HP-G54 router right off my cable modem. It goes into the wall and up to my master bedroom. In there, I have the DAP-1522 in AP mode. DHCP is off, all the settings seem good to me, however any device connecting wirelessly has all sorts of problems. If I do a ping on the computer downstairs to the Buffalo router, I consistently get anywhere from 1ms to 3500ms to Request timed out. This makes the internet on that machine EXTREMELY flaky.
I can connect to the wireless on the Buffalo router and the internet works flawlessly. However, it is an a/g router and not a/g/n. Between any two moments on the computer attached wirelessly I can get from 10Mb/s to under 1Mb/s to not even able to load the speedtest page.
Any idea what is going on or what I can try to fix this? It's totally and completely unbearable!
