By cold-booting: not just hitting reboot, but turning it off, then turning it on from cold. I've found that with some routers, that's not enough - you need to log into the router and choose the "reboot" option. If you can tell me what make it is, that'd be very helpful in terms of helping you do that.
The reason it could be the router is that it's responsible for transmitting packets, and sometimes routers break, and get confused. They're more than a modem - the bit that connects to the internet is a modem, but there's also a little computer in there acting as a server. It's the little computer that's getting confused.
For starters, anyhow, just unplugging the *router*, waiting five-ten seconds, and plugging it back in (and waiting for all the lights to come back up). Restarting the computers wouldn't hurt either. We could then think about solutions from there, but I'd be surprised if it was the ISP. |
