Having a problem switching out an access point to MT. We have about 12 users on this particular sector, and switching over to the MT AP, we only see about 6 user showing up and disconnecting every 20 seconds or so and then they come back and disconnect again. The two different errors that we get in the log file say:

00:27:24 wireless,info W2: disconnected
0:2:6f:8:a4:c1, extensive data loss

and

00:28:36 wireless,info W2: disconnected
0:11:7c:2:0:c8, unknown

All clients have a -80db or better signal. We are running 2.9beta19. Anyone know what exactly these errors mean?

TIA

Anyone?

00:27:24 wireless,info W2: disconnected
0:2:6f:8:a4:c1, extensive data loss

00:28:36 wireless,info W2: disconnected
0:11:7c:2:0:c8, unknown

All clients have a -80db or better signal. We are running 2.9beta19. Anyone know what exactly these errors mean?

I've seen the first one when either the client "disappear" suddenly (for example, power plug or antenna unplugged) or when signal quality is very bad. Remember that your -80 dBn signal don't necessary mean it's a "good" signal - there could be lots of interference or a high noise level etc.

The send one I have to guess. Perhaps you are using MAC filtering at the AP and this is a client not in the list?
Another thing I saw during test was a problem with LinkSys routers, where they associated to the AP with their wireless interface MAC address, but then sent data with their ethernet MAC address (which was then rejected by the MikroTik). But I think the error message was slightly different - something like "unauthenticated data sender" or the like...

We are going to the site today to downgrade to 2.8 and try that. We are also going to try a different wireless card if there are still issues.
The clients associate fine on the old AP and the noise/interference on this sector is minimal and all clients have enough signal strength. We had the default authentication turned on so no mac filtering in use during testing.

Thank you for replying

Well, downgraded to 2.8.27 and hooked it up and no user disconnects. Seems like a bug in 1.9beta19 going to send an email to support or is there a beta email address to send bugs to?

Have a new disconnect error in the log

jan/01/2000 04:53:34 West 2: unauth or missing data sender, 00:30:1A:00:3f:B2

Cmit, Is this the error you were refering too? I am getting this error on an Airbridge.

Mikrotik, I can associate multiple clients in the lab with 2.9beta, but when out in the field all hell breaks loose. We have just purchased two more RB532's making a total of 3 to replace other AP's in our network. If we have no choice but to run 2.9 software, are we better off waiting for a stable release and purchasing other equipment, or is my setup the problem, and you haven't seen this in your beta tests?

We have the same problem,

My RB532 runns for 22 Hours with 2.4 Ghz b/g and i get the same disconect error but i have the signal -69 to -73.
But the 2.9.18 works for 22 hours and the 2.9.19 work for 2 hours. ?

But my Wlan card get disabled??? and i have to set upp the Wlan card from scratch again. the setting are reseted .
Im sending the Supout file today.
