Any chance you could try your SP3 at work? Definitely do not do it if it would cause any issues or be against policy. Maybe talk to the IT person..I am at work so will try pinging the IP directly and also try 'nslookup' when i get home now.
I was just looking at new modem routers online and have a question- can i use an ADSL2/ADSL2+ modem if I only get ADSL 1 at home?? Sorry for the silly questions but better I find this out before i buy the wrong thing. This is the one i was looking at http://www.officeworks.com.au/shop/officeworks/tenda-w300d-wireless-n300-modem-router-tew300d
Thanks everyone for your help
I can answer about the router off the top of my head... I'll try to look into that unless someone else knows...
