Ubiquiti AF5 Connection Question

@anthonyh said in Ubiquiti AF5 Connection Question:
So, I'm here at the repeat site (yay for mobile hot spots). I swapped my 1 foot homemade CAT5e cable out for a pre-made 7 foot CAT6 cable.
When I connect the two radios together, they still negotiate at 100mbps.
When I connect each radio to my laptop (running Fedora), the link comes up as gigabit.
So, now, I'm confused. Not sure what's going on here.
This suggests that something is wrong with one of the NICs. Or both.

I do have a spare radio. I can pull the PoE injector from that one and swap it around to test I suppose.

The PoE injectors can definitely screw this up. They get in the way of the autosensing.

We are using Ubiquiti AF5's to connect two of our sites together. Because these sites do not have line of sight between them, we are leasing roofspace off a neighboring building and using it as a "repeat" site.
We've recently started having trouble with the link, and I'm working on troubleshooting it. I'm not sure where the problem lies, but my suspicion is that it may be the switch we have at the repeat site.
Can anyone think of a reason why I couldn't just eliminate the switch and conenct the two radios together directly? I'd use a crossover cable if they're not auto sensing.
Thoughts?
No reason that your should not be able to just connect them. TCP/IP does not care about a switch.
We always did this. No reason to have a switch. However a PDU for reboots can be handy.

If you can hard set the adapters (though my spidey sense tells me that scott scolded me once because there's no longer a such thing - maybe I was dreaming that?).

I wanted to try this as a test, but it'll only let you hard set the interfaces to 10-half, 10-full, 100-half, or 100-full. No gig options.

Correct. officially autosense is the only way to do GigE.

Swapped out both PoE injectors and when directly connect to each other the link is still 100Mbps. Looks like I'm bringing back a switch.

Then your radios are likely only 100mbps interfaces and you get 1gbps from the injector?
No idea what the specs of this unit are. I guess I should look before spewing random crap.

Yeah, that's how GigE is supposed to work. so that's expected and correct.

The AF5's have a gigibit interface. The radio links are faster than 100Mbps.

They are supposed to be 1Gb point-to-point.

"UBNT-Chuck" from my Ubiquiti thread (the employee who initially tested this for me) re-tested and confirmed that in his environment directly connecting the two results in a 100Mbps link. Hopefully they fix that in a future revision.
In the mean time, I put a different switch out there. We were originally using Ubiquiti's 5 port ToughSwitch. We had a spare, but I ran across a thread with lots of people complaining about throughput when using those switches in gigabit environments. The only other gigabit switch I have that'll fit in the cabinet we installed at the repeat site was a TP-LINK desktop switch. Not ideal, but if it resolves the issue it'll do for now.

Did they confirm that this is an auto-sense problem due to the POE injectors?

They just confirmed that it was a problem. Haha...
Unfortunately the issue I'm having still exists...I may start a separate thread about it if I get completely stumped.
