Muahahahaha
They called me crazy! Crazy? Me? Ha! They don't know genius when they see it....
I've just configured my laptop to treat the wireless and wired network interfaces as if they were one. Which means that if I for some reason lose one network connection (ie I unplug the network cable to wander around the house), it just keeps on going. I guess in principle, I must now have a bandwidth of 154Mb too. Shame the ADSL is only 8Mb ;)
