I have just recently bought an ipod touch 2G and love it, but I have slight problem. When I connect to my home network it connects for about 3 seconds, then immediately disconnects for 3min, then connects again for around 3min, then the internet feed dies, but the wi-fi signal is still present. I'm thinking its something with my router firewall? Will it be safe to use DMZ zone? I;m using a Belkin N router right now.
