Ok, so it's taken me a while to narrow down this problem but I finally discovered that for some reason, randomly, my Samsung T.V. (PS58C7000) when turned on somehow drops my internet connection causing a DNS error, This is where it gets weird though... my tv isn't connected to the network. I haven't figured what it is that causes my tv to issue these DNS errors but like I said at times I turn on my TV and the DNS is unable to be resolved (Using OpenDNS) on my router (Netgear DG834G).but when I turn my TV off the problem is fixed almost instantaneously. The TV can only be connected to the network by A Wired connection from it to the router. I have my PS3 and PC connected to the TV but NO ethernet cable connecting the TV to the router. It really comes down to a game of chance when I turn on my TV weather it will screw up my internet connection or not but as far as I'm concerned it shouldn't be doing this.... Any suggestions on how to fix this would be appreciated.
