Well, note to self: don't try doing tech support when late at night.

That ADSL modem router WiFi firewall box thingy that apparently wouldn't work anymore?

It does work.

It did come up on its default address of 192.168.1.1, but there was a reason I'd failed to be able to connect to it. Now, I'm perfectly aware that a /24 netmask on my PC would prevent my machine on 192.168.0.5 being able to see it, so I'd widened the netmask to a /16.

What I'd forgotten, at 01:00, is that the router would then receive the packets, but be unable to return them, because its netmask was still a /24.

Last night, I switched my IP address to 192.168.1.5, and suddenly the router was there after all. In a totally virgin state, admittedly, but that's why I have a backup of its configuration. Uploaded that, let it restart, reverted my IP address, and it was all hunky dorey again.

Oh well, it's nice to know that we have a spare working router if it does decide to die (and £25 is not a lot of money for that peace of mind). And that I know where all the password and logon details are.

In other news, the graphics card, the one that wants a minimum 450W PSU and that had been somewhat flaky when run with a 430W PSU, didn't get any more reliable when hooked up to a 700W PSU. So we also have a spare PSU for next time one dies.
