I have a 1142 running W7 Autonomous software. WPA2 Pre-Shared key.
Everything is working - clients connect at 300MB M15 however performance is poor, around 110MB/sec
A show proc cpu shows 100% CPU due to interrupt (not a process)
Anyone seen this before? Both 12.5 and V15 IOS seem to exhibit the same issue.
As per your query i can suggest you the following solution-
To exceed the target CPU utilization by a small amount, or a momentary spike in utilization, is not an indication of a problem that needs investigation.
Hope this will help you.
Your response doesn't even consider my post - I have constant 100% CPU on the 5GHZ Radio when a user attempts to move traffic. The CPU drops when the traffic goes away.
However the performance of the radio is less than 150MB
Ok, what does your logs say?
Only on 5 Ghz? I've never seen something like that before.
I'd like to say that it could be traffic re-transmission.
