I've been going through routers left and right since October 2012; same symptoms across each one. Works fine for X amount of time (X is anywhere from 1 week to 6 months) and then randomly I cannot access information outside of the network via lan or wlan. I've used two D-Link routers (DGL-4300, DIR-655), TP-Link TL-WR1043ND, and now an Asus RT-N16. I am able to transmit without issue to my NAS and 4p folding rig, but outside of the network goes no where. Releasing/renewing/flushing dns only fixes the problem for 10-60 minutes, and then the same issue pops up. I'm at the point of pulling my hair out - anything else I can try to narrow this down and hopefully resolve it?
