Atheros problem.

[subha]

we use Atheros card in star-os , firmware :-MIPS-COMPLEX Edition 1.1.13c (build 2083)
we are getting time time reboot problem within (2 to 10 mins)
we have done following things

i.we use upt copper cable about 40 to 45 meters.
ii.Power adapter is 24 v 1.5 A
iii. patch cable and POE are use as manufacture company recommended.

Note :- At the time when we are facing time time reboot problem with in (3 to 10 mins ) we change another POE .Then its seems to reboot with in (30 to 50 secs) . After then we again change the same POE which was use last time , now it is working . it began 1 hrs.

Is any body facing this kinds of problem ?
If then send solution.

subha.

What are you using for termination on the cat5 cable? It is recommended to use "punchdown jacks" or "keystone jacks" depending on which side of the pond you are on and what they are referenced as.

Problem with 90% of RJ45 jacks is that they are mad for stranded cat5 cable and most cat5 cable is use out there is actually solid cat 5 so you coudl have a dodgy rj45 crimp on your cable some where down alonf the line.

we use cat5 cable and punchdown jacks too.

Sounds most strange. When you say reboot, are you referring to the whole unit rebooting? as in the the WRAP/WAR you are using?
Have you checked that you have not inadvertantly set ping watchdog on to ping an IP across a link that may be considered "dodgy" and hence you are getting the random reboots as the link goes up & down.

We have come across a situation where a dodgy ethernet port on the WRAP was causing it to lock up, and a physical power removal was the only way to get it back.

In all situations where I have come across "random reboots" it has been a power issue. Have you tried swapping the power supply? Your power supply maybe gone faulty and is not able to deliver the required wattage to power the board. When you measure the power supply with a voltmeter it will read fine, but when there is load put on it, and voltage will drop away down due to a faulty regulator in the psu.

My steps towards solving your issue would be as follows:
1. check RJ45's/punchdowns (you have already done so)
2. Swap the psu
3. Swap POE in case of dampness/oxidisation on the pins (you have already done)
4. Swap the WRAP/WAR for a spare. Powering the "faulty" WRAP/WAR up on a bench and leave it powered up is no good. It needs to be under load hence you have to replace the board and put another one into the live environmnet
5. Swap radio cards (a long shot)
6. Still no joy? Go to the pub because it can be nothing else :)
