BT ADSL Modem IP Weirdness

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.

  1. odd setup I know – she was originally on cable so just needed the Linksys, but then moved to an ADSL-only area []
