Hi wireless expert:
These days,i have a problem that is all clients cannot associate to 5G wifi,only 2.4G OK.There are wlc and AP module as below:
WLC: 2504 ; software version:18.104.22.168
i have run "debug client xx.xx.xx.xx.xx.xx" command to try get the associate info.but unfortunately,there is no any info display.
other info：5G channel don't have interference,and channel utilization is so low.
So i don't know what reason about this problem,i guess the ap drop all traffic of 5G ,Can you tell me the probably reason？
disable 802.11b/g/n (2.4 Ghz) on the wlan and try to connect a clinet to ssid with 5Ghz only...and see the logs in WLC.
If possible paste here as well to analyze the root cause.....
i have disabled 2.4g，just only have 5g.And client cannot associate to 5g ssid.the logging don’t have useful info，and debug client mac-address have no output....
so，i guess ap drop all traffic of 5g
Could be CSCus83638.
Is there a reason why the controller/AP is running an old Engineering release image? Is it possible to upgrade the firmware of the controller?
i will test the workaround
See if it's possible to upgrade the firmware of the controller to, say, the latest 8.5.
Same thing. 22.214.171.124 and 3700's - just wasn't making any sense. Restarted 2 of the AP's and now they respond and will associate; although I gather this may be a temporary fix. Problem is - how do you even FIND which AP's are in this state ? I just hit the ones that really should have had connections and hadn't, but this is pretty tedious.
