Hi all,

Anyone else seen high 2.4ghz channel utilization after upgrading from 8.10.0.9_88493 to 8.11.2.1_88699? No config changes before or after upgrading but seeing 99% utilization with low/0 clients. Have 167 IAPs in the instant cluster total.

Before (firmware 8.10.0.9_88493):

After (firmware 8.11.2.1_88699):

Tried many different combinations of settings but I can't seem to figure out what is causing the 99% util.

Known issue that is being worked on.

It's good to hear it's not just us then, was starting to worry it was our setup.

Be interesting to findout what sort of issue it was since it does seem to effect the 2.4Ghz radios so it's not just a reporting issue.

I don't have specifics, but a reboot is the only "workaround" for the issue at this time.

I downgraded our clusters back to 8.10.0.9 which fixed the issue for us.

I am using AP-615 with 8.11.1.2 and the utilization pf 2.4 radios are normal.
