If you've ever had your home network lose Internet connectivity without warning, you've got plenty of company.
Several readers responded to last week's column about a California man who periodically lost his home Internet connection, but regained it after unplugging, then powering-up his home network's Netgear router.
Some readers had different ideas than I did. I suggested that he ask his Internet service provider if his router and Internet modem were compatible with the provider's network. I also said the maker of Netgear routers recommends eliminating firewall software on home PCs and relying on the router's firewall -- a risky strategy, according to security experts.
Frank Bulk of Sioux Center, Iowa, brings a technical perspective as the manager of the Internet help desk for Iowa phone company Premier Communications.
"The more likely issue is a bad router, a bad power supply for that router or a [design] bug in that router," Bulk said. "Very rarely is it the cable or DSL modem."
The easiest and least expensive solution is to upgrade the router's "firmware," a bit of computer code you can download from the manufacturer's website, he said. If that doesn't work, adjust the router's settings back to their "default " position and try reinstalling the router on your network. If neither solution works, you probably need a new router or a new router power supply -- but most likely the former.
"Sometimes a faulty power supply results in an intermittent [Internet outage] issue. But it's quite rare, about one in 500 in our experience," Bulk said.
Todd Young of Inver Grove Heights says the fix for a Netgear router can be as simple as restarting it the right way.
