Why use omni-directional antennas for a point to point link, not only are you wasting power output in directions you dont need it, but you are going to get noise from directions you don't need to listen to. Not to mention it's irresponsible use of a free spectrum that's to be shared responsibly by all, ie. one should use as little power focused in the smallest area possible to get the job done. You have to either put them in Point to Point mode or one in AP and one in client mode. A client (endpoint) access point should never have an omni-directional antenna on it. > > SITE A > SITE B > > Radio Linksys WAP11b v2.6 P2MP > Linksys WAP11b v2.6 P2MP Antenna 15db Omni > 15db Omni SSID > Enabled > Enabled Basic Rate 1-2 Mbps > 1-2 Mbps > > *** all other settings are Either in their Default or disabled **** > > I use an ordinary RG58 cable since I cant fnd an LMR-400 cable here. > IM still waiting for it from Hyperlink.

You'll have much better results although you'll have to aim them up. using 24dBi directionals you'll likely have less noise to deal with, and have 18 more dB of signal between your points. I would also recommend using the point to multipoint mode of the AP's, not 802.11 AP/Client mode. > thanks in ADVANCE > > George As long as you have a clear line of sight, and guessing 5dB of cable loss on each end you should easily be able to make the link work with 15dBI directional antenna's. Remember - smaller is better as long as the link works because you won't be picking up garbage noise in your link from distant areas, and you won't be putting your overpower signal into a place that you might want to put something else up later. -- Jason Straight [EMAIL PROTECTED] icq: 1796276 pgp: http://www.JeetKuneDoMaster.net/~jason/pubkey.asc -- general wireless list, a bawug thing <http://www.bawug.org/> [un]subscribe: http://lists.bawug.org/mailman/listinfo/wireless
