Had an issue like this once with an X-10 video system. We had an 802.11 client who had one. Their wireless failed when it was on. > Hopefully someone can help you with the following questions: > > - What can be done to mitigate this?

Even the most directional antenna's will still pick up a lot from the back, when it's so close. Especially when any directional antenna you could get would have a lot more gain than any whip antenna the AP probably came with. Try to spread out the channels between you and him, try polarizing your antennas horizontally, try shielding your antenna's with something from his direction? Of course then each client will have to do the same somehow probably in that close proximity. I don't know if any of that will work, but maybe worth a try. > - Is there any software or hardware that can be purchased to track down > 2.4Ghz interference? Spectrum analyzer. On the expensive. A prism card with software spectrum analyzer on the cheap, but you get what you pay for. - -- Jason Straight [EMAIL PROTECTED] [EMAIL PROTECTED] SkyCon Networks phone: (231)627-3528 http://www.skycon.net/ ICQ: 1796276 pgp: http://www.jeetkunedomaster.net/~junfan/pgp.key -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iQCVAwUBP7LRrhFHZPcobeHxAQLrfgP8DyXSeiHQHqrx5gtaIS0uk0SJh3HHnbtG 2WE9BecunZ4JIjNvpV5E9KzEm/kQl+fOpHH9SUzxnDs8QJuoNFnivun15Df13r6O xd97gNRIPIz01jdCPr8K4DLaUvKdjZZTifbOPGfijUrigpe34wu8tErfvRaRc6ph 6oJGWE6qaeA= =0eMJ -----END PGP SIGNATURE----- -- general wireless list, a bawug thing <http://www.bawug.org/> [un]subscribe: http://lists.bawug.org/mailman/listinfo/wireless
