I've just upgraded a customer controller from 10.41.05 to 10.41.10 and now the dashboard show 213 APs with low link speed = all APs.
I've checked one switch with about 10 APs and the "show port no" result is that all the AP ports are actual speed/duplex of 1000/full.
Tried a reboot of 10 APs but no change.
If you click on the low link speed counter the pop-up list only 3 APs - not sure whether that is the max that is shown in this window.
I'd see the same result on my lab controller - even there are only 8 out of 12 with low link speed - I know that is also not correct.
Is that a known issue !?
