We're having a rather odd problem. We have an SMC router. In February we got a new computer, and had a lot of trouble installing the router. When we finally got it installed, the factory default must have been activated, and our network went from secured with a personal SSID to unsecured with the SSID "SMC." We once tried to secure it through the SMC site, but ended up not being able to access the internet at all for no apparent reason. After two hours on the phone with someone from SMC, he managed to restore it to defaults again, and we were so relieved to have the internet back that we gave up on securing it for awhile and are a bit scared to try again.
The issue is this--we recently moved the router (which connects to a cable modem through time warner) literally next to one of the laptops. Most of the time, it works fine, though it flickers throughout the day. However, at certain times, it stops finding the signal for long periods of time or finds it sporadically and connects but has limited connectivity then drops it again immediately. When the router was in our basement, we often had to reset it to get our signal back, but in this case resetting it does not seem to help. Over the summer we brought the router with us out of state, set it up, and had NO problems even though it was on a different floor than any of the computers. The problems began again several hours after hooking it up at home. We are befuddled. Any help would be greatly appreciated.
