3602i Errors in log, bad throughput

jonesea · ‎10-02-2013

I just acquared a 3602i. It was running lightweight, but I changed it to autonomous.

From the start I notced absomal throughput when only 10-20 feet away, bouncing from 0 to 7 Mb/s when using iperf over a 30 second period. If I used the same client on my 3502, I get a solid consistant throughput of 37 Mb/s.

When I looked at the logs, I noticed the following section:

Those errors are none that I have seen before.

Ideas? I have an idea what is wrong, but I wanted some feedback before suggesting anything. The performance is bad with more than just this specific client that I'm testing with.

Thanks

What IOS version you running here ? Also compare "show dot11 associations " output with 3602 & 3502 when client connected. Specially "current rate" parameter.

Some of the error msg like hardware related like "Radio interface bus down" etc. I would upgrade the software & see.

3602i only should work in lap mode, what IOS you used to covert it to AP mode?

I'm running the latest autonomous code (July 31st 2013) - ap3g2-k9w7-xx.152-4.JA1 , but I was also running an old one and had the same errors as I originally posted.

I finally got around the testing again with my two APs

On my troubled 3602i:

> 3602i only should work in lap mode, what IOS you used to covert it to AP mode?

Autonomous code has been released by Cisco, it's available from the support/download page. While I totally understand these classes of lighweight radios were meant to only be used this way and that autonomous was for surveying with a limited feature set, my 3502i has worked flawless for 4+ months.

Also, I also don't think the errors I'm seeing are a result of using the Autonomous mode, these seem like much lower level of errors that woudl impact your ability to even do a proper suvrey.

Gerad Parent · ‎11-15-2013

Endaff,

Did you ever find an fix for this (other than switching to the 3502)? We have been having the same issue for quite a while. We are using 2602 radios for both the RB and NRB. Switching from 1242's radios to the 2602's seemed to work for a bit, but the same logs have shown back up, and the NRB's drop there assococation periodically, but do usually reassociate on their own. The problem is it is causing troubles with our end devices connecting to the NRB while the connection is down. Any information you can provide would be appreciated. Thanks

Leo Laohoo · ‎11-15-2013

Don't use IOS version 15.0, if possible. Use 12.4.

Sandeep Choudhary · ‎11-15-2013

Hi Endaf,

Please try to add the infrastructure-client command root access point radio stops the message.

If this is only for a specific client looks like , client related issue. That MAC OUI look like an intel card, ensure that it is running the latest driver.Hope that helps.

Hope it helps.

No, I have not resolved this. I havn't had time to work on this lately, but I'm in the process of moving this specific radio to a WLC enviorment to test again.

I'm trying to determine if this is a hardware fault or firmware issue.
