Could be that the switch is only 100MB.

It would help if you would be more precise and confirm your findings with screenshots.
What steps did you perform to troubleshoot the issue.

HI Ronald,

I have try to resolve the issue from switch end, i also changed to gb port( which port is configured for Gb).it's not reflecting.

Are the AP and the switch port set to auto negotiate.

It could also be that the CAT cabling / patch cable isn't good so you'd either messure it or try another CAT cable and patch link.

You can try to change the port advertisement for the negotiation on the Switch , so that it has only the option 1000Base ?

PoE maybe an issue?

Making an assumption that everything was configured correctly before the upgrade, I would be very suspicious of the cable. Please relocate 1 of the APs onto the switch (same switch/port) with a different cable.
PoE will work on either pair of links in a cable but Gig requires all 8 strands

I'd assume that the problem was there before but v9 doesn't include the feature to show "APs with low link speed" - now after the upgrade EX3 has the option to see issues like that in the controller GUI dashboard... I think no one checks every switch port with a AP for link speed via CLI 🙂

But as I've mentioned it comes down to a detailed problem description or we all could only guess and use our crystall ball.

I saw the same thing after upgrading to 10.x, but never got around to testing each link. I concur that it is most likely the cable plant. I might do some cable testing today and report back.

I was able to get around to testing one of these today. There was a cable fault on the Ethernet path according to my fluke tester. Plugging the AP directly into the same switch port with a new cable caused it to negotiate at a Gig.
