My sister’s wireless network has been playing up for a few weeks, and looking at it today I found out why. She has a BT ADSL modem, into which is plugged a Linksys router1. I originally helped her set it up over the phone, and after finding that the BT modem IP was 192.168.0.1, told her to configure the Linksys as 192.168.0.2. She had all sorts of problems with random disconnects, and it turns out that the BT modem demands the use of 192.168.0.2 as well. Weird. Setting a higher IP for the Linksys has, I hope, solved the problems.

I hop that is an IP address internal to your Mum’s home network and you are not giving out her IP address to all and sundry!
Is ok, it’s an internal one but I changed the numbers anyway
And it was your sister not your mother… I must learn to read properly. I was thinking about my mum’s broadband connection which is, apparently, not working and which I have to sort out when I visit.
