+ 1 Votes wired is always better than wireless Greybeard770 June 17, 2013 at 9:57am PST Has there been any environment changes that might affect wireless? That could be a new cordless phone, new close neighbor, new electronic something. I was thinking maybe you had a power saving option of cutting power to your NICs to extend battery life but since it's kind of sudden I would tend to rule that out. I generally consider that option a bad idea. Try it hardwired to your router.
