PS3 DNS Error

I recently bought a wireless router (TP Link) and am using it to connect my PS3 online. I have been having trouble with this DNS error that keeps popping up. I start up and everything seems to be okay; I can browse the web, can log on to PSN and can play Home. I keep getting disconnected after about 15mins, then I can't log on to PSN or browse the web after. If I reset the router, the same thing happens - it's okay for 15mins, then disconnects. I didn't have this problem when I connected without the wireless router so I'm figuring it's the wireless router.

I am currently using the following settings for the wireless:

LAN
IP Address: 192.168.5.1
Subnet Mask: 255.255.255.0

Wireless
Wireless Radio: Enable
Name (SSID): xxxxxx
Channel: Auto
Mode: 11bgn mixed
Channel Width: Automatic
Max Tx Rate: 300Mbps

WAN
IP Address: 192.168.1.2 Dynamic IP
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS Server: 208.67.222.222 , 208.67.220.220


I read somewhere that I should change the PS3 DNS settings to 208.67.222.222 , 208.67.220.220. I probably messed up somewhere in here, as I changed the Router DNS server addresses to the same. Help is much appreciated.

Help anyone? Or is this question for the console boards?

the DNS change is to the OpenDNS project and I use it myself.

your bigger issue is the disconnect.

suggest you start by forcing G-Mode only. ( Mode: 11bgn mixed )
