a few years ago, i purchased a 11mps wireless access point for my work place. we have a warehouse, and with a dell truemobile pcmpia card (lucient in disguise), i was able to go to the back of the warehouse aprox 50 metres and the signal was registering as low and i was very happy with that range. The signal had to go through two sets of block bricks that say 20 cm wide. At my house I have a adsl wireless modem which my dell D610 with built in wireless networking can access from all the house, here are some screen shots of the signals i got.
I have floor boards, but even going through garage outside, which is those big bricks again, i never lost signal. I ended going down the driveway, madly taking screenshots, pasting into adobe photoshot, saving to jpeg format and then back to adding to forum post, all while still connected to internet.
