No - I haven't got as far as making our Suse box to do wirelesss - yet. But its a small part of the plan.... We have decided to cover our campus with Wireless acces points. We went for 801.11g at a potential of 54Mb/s but with the longer range of the old 801.11b standard. At the moment this gives us more compatibility with existing kit - especially PDAs which only seem to have 801.11b cards. Of course I soon discover there is much to learn... Channels 1 to 14 in the UK. I set my AP to channel 12. Our PDAs would not pick it up. Why? Because only channels 1 to 11 are 'universal'; channels 12 to 14 are only available in UK (EEC?) In the process I also discover that although the channels are 5MHz apart each channel is 22MHz wide so there are only 3 effective non overlapping channels - so some though must be given to channel settings on adjacent APs to get maximum benefit vs coverage. I'm not sure as so decide which channel to use - if some channels are used peramanently by DECT phones, BlueTooth, etc how will I know? Is there any reporting software utilties? Then there is security. We've all heared of those tin cans used as aerials by hackers driving around in cars. So I set up 128bit WEP in the APs. Agh...the PDAs only cater for 64bit (not that it told me anywhere - it was just impossible to type in the key - and they wouldn't connect..) QUESTIONS: Why does the AP give me 4 keys? (but only transmit one?) Is it a random choice for me? Do I assign keys to different user groups so that I can forbid groups for connecting? What's the idea? Should I have the same key in the mobile (which only accepts one?) Can it be any of the 4 keys? Should I set the SSID to be the same for the whole campus? Does this make moving between access points easier (no need to select as you migrate?) (I don't think its quite as transparent as mobile phone cells there seems to a a gap of several seconds while it changes - and tends to stick with existing weak signal even if you are right next to another) Or should I give a descriptive name to each AP? If lots of users are in an area covered my more than one AP do the clients share out the connections? Do they pick the lowest channel or highest? At random? Or do they pick on the strength of the signal? Or the loading of the Access points? Anyone with experience in these matters? If so, what else would you draw my attention to?
