My DNS seems to drop out randomly about 1 to 3 times a day for the last few months. All wifi devices are still connected to the wireless router (Shaw's SMC8014WN), PS3 is hardwired and it gets booted from the PS network too. When I access the router status page it displays a bunch of 0s in the DNS section. It usually just "magically" starts working again within 2 to 5min; very annoying! All connections/cables are good (I've tried multiple cables, no difference), any ideas on how to resolve this? New router? Bad house wiring?
