Well, i'm having some problems with DNS lately. I use a Linksys E2500 router that connects the modem to the PC and my PS3, and sometimes i get DNS errors that don't allow me to use the router (connecting the modem directly to the PC or PS3 works just fine). My PC has a Realtek RTL8139 Family PCI Fast Ethernet NIC (dated as of 2001 with driver version 5.398.613.2003, because i can't update anything from Realtek's website). I have some port data for Call Of Duty and Playstation Network configured with Port Range Forwarding and Triggering together with DMZ configured to my PS3 MAC Address, and looks just fine so i don't think that's the problem. When i reset the router to default configurations, upload the old configurations and reboot the modem, everything works again. But i'm pretty sure that the problems will come back... The DNS i'm using right now: Primary: 18.104.22.168 Secondary: 22.214.171.124 Every help would be much appreciated. And if you guys need ipconfig screenshots or any other information, just ask that i'll provide it as soon as possible.
