I bought an Archer C2, upgraded to the latest firmware, and replaced my very old dir-300 (I bought this one back in 2009 and it was time to "upgrade")

My wireless devices get almost NO internet connection. I can't watch netflix on HD, and my online gaming is almost impossible, since I get almost no connection and I get kicked and disconnected once in a while. I connect the dir-300 and the PS3 starts working flawlessly again.

Ubiquity Router (gateway) with Internet access and DHCP server<----> Tp-link gigabit lan switch <----> ArcherC2 (connected to the LAN port, as a switch/AP, dhcp disabled, all security settings disabled) <~~~2.4Ghz wifi~~~> PS3/wireless desktop/cellphones

I DON'T use the WAN port, because I use the ArcherC2 mostly as an .

I tried disabling absolutely every single feature in the ARcherC2, and I still can't get online to any game for long periods, nor watch netflix in an acceptable image quality.

Connecting from the wired desktops to the wireless devices inside the same network subnet seem to work OK, since I was able to stream a 720p movie to the PS3 as a media center.

The internet connection on the other hand is terribly slow, unusable. It works fine when I connect the dir-300 router/ap again.

Does anyone know what could be the cause?

Thanks!
