actually - the one your seeing in the SR101 log is for ADSL IP and not internal network IP's (although what jid says still stands) - for whatever reason sky force their routers to renew the IP lease every 15 minutes or what not - I dont know why, I think its only MER connections they do this on (but could be wrong)...is yours connected via MER? - if you ever swap sky (MER) routers around you will find that the new one will not connect until the new lease has come through, however if you put in a non-Sky (MER) router you force PPPoA and it will work instantly, and same coming from PPPoA to MER, it is only switching between MER routers that you have to wait
