Make sure you use a Belgacom-approved ADSL modem, and you should be able to connect that to any wireless access point you want. I'm using Apple Airport "Snow" base stations with a Belgacom-approved ADSL modem and a Skynet account, and I'm going to be soon switching to Apple Airport Extreme base stations (including WDS mode so that I can get better wireless coverage over the house). After that, I'm going to be using Soekris 4521 and 4501 boxes running OpenBSD (or maybe FreeBSD) on CompactFlash and using Senao high-power/high-sensitivity 802.11a/b/g cards with external antennas. I'm seriously thinking about tying them all together with a home power network backbone (~14Mbps theoretical), so that I can put up a base station and extend my coverage anywhere I have an outlet. > The reason I ask is because the signal > strength when moving around drops to an unacceptable level. Does > the difference in 802.11 standards effect the signal strength? The 802.11a stuff will not get nearly as good coverage, due to the higher frequency. If you're using 802.11g, that might cause problems with other 802.11b devices, depending on the configuration. If you're using it in 802.11g-only mode, you will probably get less coverage than if you were using it in backwards-compatible b/g combined mode. If you're having problems, you could use higher-power/higher-sensitivity cards in your computers, as well as perhaps using external connected to the card via special cables, and that might do what you need. If not, you'll need to replace the base station with something more powerful/sensitive, or possibly use multiple base stations and connect them all up together. -- Brad Knowles, "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.
