How far apart are the antennas? What antennas are you using? Is there any sheet metal in the area? ie building sides, a parking lot full of cars you're shooting over, etc. What sort of feed cable did you use? How long is the bridge to antenna run?
Lost association means a lost beacon. You can tune 350 series workgroup bridges so they never disassociate and I'd suspect the same config is possible with a full bridge, but I've never tried it - look for 'parent' and set it to the MAC address of the root bridge and it might just fix your problem. Be aware that Aironet has a *shitty* history on the 35x series - I've RMA'd something like ten AP35x ... the radio cards just drop to 1mw of output and never recover ... its a thermal thing. Pictures of the antennas and the path between buildings would help, along with stats from the radios. Are you seeing a lot of FCS errors? If you've got reflectors in the area, and you've got the juice cranked for a shot across a parking lot, and you're using a wide angle antenna, you could very well have some multipath issue ... Use 11.21 code, avoid 12.0T as it is experimental. The systems I have with 11.21 are well behaved, the ones with 11.07 are not, and I avoid experimental stuff unless I absolutely must have some feature that isn't in the mainline code yet. 802.11b is CSMA/CA - if you've got neighbors using the same channel as your system you can turn on RTS/CTS and set a low threshold - when *any* 802.11b device sees a frame with a network allocation vector it will honor it - its not SSID dependent. That is *deep* 802.11b and if you've really got trouble like that, maybe we ought to talk in person :-) Firesox wrote: > I have two Arionet 350s, one is root bridge and the other is non-root bridge > without client. > They are connecting two buildings. > > I am getting following messages and two bridges seems to lose authentication > very often. > > ON Root Bridge > 15 days, 02:29:30 (Info): Station [RootBridge]004096571b41 Reassociated > 15 days, 02:29:30 (Info): Station [RootBridge]004096571b41 Authenticated > 15 days, 02:29:30 (Info): Deauthenticating [RootBridge]004096571b41, reason > "Not Authenticated" > 15 days, 02:29:29 (Info): Deauthentication from [RootBridge]004096571b41, > reason "Not Authenticated" > > ON Non-Root Bridge without client > 12 days, 01:41:47 (Info): Lost Association with Parent > 12 days, 01:41:27 (Info): Associated to Parent [TAB-WB01]004096571136 > 12 days, 01:41:26 (Warning): Lost Authentication with Parent > 12 days, 01:07:54 (Info): Associated to Parent [TAB-WB01]004096571136 > 12 days, 01:07:54 (Warning): Lost Authentication with Parent > 12 days, 01:07:54 (Info): Associated to Parent [TAB-WB01]004096571136 > 12 days, 01:07:54 (Info): Deauthenticating [TAB-WB01]004096571136, reason > "Not Authenticated" > > I am not sure what is causing this problem, but I am losing connectivity > every time it happens.
