Hello,

I have an Ap (MR46E) that has an alert of "Ethernet uplink speed degraded".

I've checked the cable by investigating the port...no errors, CRCs, drops...cable seems good.

I've bounced the port.

I have the port set for auto/auto and the port is showing 100/full.

It's firmware is fully updated.

I've set the port for 1000/full, but once I set the speed to 1000, the AP drops and the port shows not connected.

Port is showing power is still being issued with 30w.

Not sure what is happening...

This Ap has been running fine for over a year and this just started happening a week ago.

Any ideas???

Does the cable test show all pairs are good? If you connect another device using the same cabling and switch port, does that come up at 1Gbps?

well I didn't do a cable test per se`...I just checked the port using cli command sh int gi0/x.

port shows clean.

I actually just noticed a few others showing the same alerts from several different sites. I have 5 locations around the globe.

I had this same scenario occur yesterday with one MR36 with nothing changing in the equation. I believe it's possibly attributed to one AP that is rarely or seldomly used. Cables are good, firmware all up-to-date.

I just fixed my MR36 that had a similar issue as you described above. I turned off the port and turned it back on. Nothing else in the equation changed. Not sure what caused it to change to 1OOMB full duplex from 1Gig auto negotiate. But it fixed mine.

just tried bouncing the port on 2 different APs but no joy.

How about disabling the port for 60-90 seconds then enabling it? That's what worked for me. Hope it works for you too.

Are you using Cat6, Cat5e or Cat5?

If it's connected via structured cabling how old is that cabling? I would suggest getting a cable installer that has a decent tester like a Fluke branded tester to have a look, it could be a crushed wire, bad resistance etc that could be causing the problem. It's not as simple as getting a link and speed negotiation.
