MAC Address and Telstra Every so often, Telstra's ADSL service spits the dummy. The problem for me is that I'm connected via a router rather than Windows which means zero support. Generally this is ok as I try connecting with OS X but today OS X worked and Router didn't. After some stuffing around.....I changed the MAC address on the wired side of the router...bingo....connected. It seems that my router's MAC address must have been locked or such. Anyway...if someone find this useful. Bonus is that everything seems HEAPS faster which I'm not going to argue with.
