Cable modem hooked up to a Belkin N+ wireless router. Modem-router environment is 192.168.100.x. Router-wireless environment is 192.168.2.x.
For several weeks, the Internet connection has been flaky, cutting out at the modem about once a day. This throws the router, which fails to reconnect (I’m sure it used to). I frequently restart it to get things back up and running.
Until this Saturday that is, when the Internet went down for about an hour. Restarted the modem - but no Internet. Called the ISP support line and discovered the modem had adopted a 169.x.x.x local address for some reason. Unplugged everything and got the modem back online.
Now the router won’t connect to the modem at all. I can hook the computer to the router admin screen at its local address, both wirelessly and with cable. And I can hook the computer up to the modem by cable and get online (which it what I’m doing now).
I’ve done a “factory restore” of the router, but it still won’t see the modem.
If I can plug the computer into the modem and get online, does it follow that I should be able to plug the router into the modem and it should be able to get online, or is there something I’m missing? Or is it, as I suspect, a coincidental hardware fault at the “Modem” socket on the router?
