SSID missing on one device, fine on all others

[charlesr]

My father in law is round and his old XP laptop cannot see my router. Everyone's phones and ipads and stuff can see it fine. However, his laptop can see the neighbours' routers....

Any ideas? I tried manually assigning the details. Fail.

Do they both support the same mode and encryption, B/G/N?
Some older laptops may only be B/G and support upto WPA.

It's G only on the laptop, but I think it does WPA2 and AES.
I have some other G only devices working (joggler / squeezeboxes) so had discounted that Very odd. Oh, and I set up an unsecured guest network and it couldn't see that either crazy....

And it used to connect last time he was here

Possibly it's set to beyond channel 11 which some old hardware can't use.

EB is the winner! Last time he came, I was on ch7, but then the neighbour's BT router decided to change itself to 7 (WHY???????? gah), so I changed mine to 13. Must be that. He isn't here now though.

And once he realised the neighbour was with BT, he just used their connection with "Fon" (he is also a BT customer, so you can steal anyone else's bandwidth after logging into your BT account after being prompted in a browser......)
