Installed first UBNT Air fiber unit today

How far is the link? Is 700ft is how far the link is? if so then you should be getting all your connection.

First sentence its a 700 ft shot..

I never messed around with the Airfiber I only seen it in person at UWC chicago have you tried asking in Ubnt forum? I have heard on ubnt forum they use iperf or doing speed test inside MT between airfiber.

"Cant get but 100meg download"

Does that mean from the upstream to the downstream side, you are only getting 100mbit instead of the full speed?

If thats the case, i would check if all the network ports, routers and switches in place are gigabit speed or just 100mbit.

Ray.. Yes from Verizon he has a 300 meg fios connection, at the ONT with the verizon router or a laptop plugged directly into the ONT we get 300 down megs 65 megs up.

After we plug in the airfiber master go over to the slave and plug in the Verizon router or laptop we only get 100 megs or less thruput but upload is fine.

The slave unit says in stats TX=756 megs RX only 125 megs so to me that means I am only seeing 125 megs thruput capability on the radio from master to slave? Once I get this difference figured out I am sure that will fix the issues.

I dont have two free laptops to try IPERF but if the radio is reporting a large variance like that something is wrong.

The Master radio is on the eave of a 2 story house with perfect LOS to the 2 story building where the slave is on the roof with a 5 ft NON pen roof mount both sides are about -62 RX and TX after about an hour of aligning.

I am guessing for some reason the RX on the slave is not working properly or TX on the master is not putting out enough power even though its I think at 30 dB whatever the max is.

Customer sent me an E-mail this morning 2 AM (he owns a cyber cafer) after closing to tell me the results again.

Now the only other thing I can think of is that the radio (slave side) being on the roof is getting some reflection from the 5 ft edge / wall of the edge of the roof, but we are about 30 feet from the edge in the middle of the roof with clear LOS to the house 700 ft away and about

Here is the GPS for the Slave
34° 0'43.97"N
117°44'20.37"W

GPS for Master
34° 0'44.21"N
117°44'26.50"W

Its probably to hot. We installed our first one yesterday - best we could get was -61 (which indicates 50% signal?/link is ~2 miles) however it does show at 740/740. When we called ubnt support they said that was borderline to hot.

Our strange thing is this morning we can't ping the slave side or access it via web interface but its still passing traffic - not too reassuring :-/

I left these ones to out of band management using the slave management ethernet hooked to the lan of the customer network. They can log into the slave but no access or ping to the master side from the local lan. If we log into the slave radio we can ping the master side from within the radio just no access from the lan directly or thru the slave radio..

I figured I would be able to log in that way?

When we first setup the link we were able to ping and access both.

What I really fricken hate about this unit is the LED on the bottom of the radio L A M E!!!! should be on the back at least.

Had a guy hanging off the eave of a roof trying to read the damn thing upside down!

Its really a 4 person job. One to align and one to read off the numbers from below at each side of the link, and why not include the speed test option like all the other UBNT products? or the spectrum tool just so you can see to make sure your not close to any noise in the same spectrum..

Oyyy Vey.. I dont want to have to go back out and mess with it but I guess we will have to.

Do you have remote access to it? I would reduce the output power and see what happens

Not yet that was the first thing i was going to try. Its up in Chino hills about an hour away. Waiting for the owner to wake up and set up the firewall (monowall) to get me some port forward rules to mess with it.

The only thing is if I cant get to the master I will have to go up and use the ladder to plug into the master to config it on site. The Slave I can get to down below or from his own lan..

Yeah we didn't even use the LED - just used our phones to login remotely to our server and check the signal

Update on my problem of not accessing it.

We can log in backwards to it - we still have a radwin link as "back up" that we plugged into here at the office and can access it just fine through the internet port

reply to viperm
I don't have any of these, so I'm speculating.

What I have read about 24Ghz in general with AF and other radio's is it's nothing like dialing in 5Ghz or 2.4. These things are like laser beams. It has to be dead nuts on.

From other posts of people having issues, when the data rates don't match up, it's alignment.

Hi,
At 700ft, you should see a much higher signal than -59dBm. My first thought is alignment.

Alignment is very important with these devices. Have you taken a look through the QSG:
»dl.ubnt.com/guides/airfiber/airF···_QSG.pdf
There are a few pages on alignment (starting at page 20).

If you have any more specifics, feel free to shoot me an email (matt@ubnt.com).

Thanks,
Matt

Matt I am beggining to think so as well but they are so close cant see how we can be that far off we have aligned hundreds of PTP licensed links and 24 gig stuff and never been had any issues.

Is it possible the power being at max could be causing issues?

I am trying to get remote access to view and test this evening.

One question is how do I get to the remote radio if its not hooked up to the remote lan on the slave side.

Slave radio management interface is plugged into local lan.

Master radio we are using just the data port only. We left the management interface unplugged thinking we could get to it remotely from the slave side since it was plugged into the local lan via management port?

We can ping the remote radio but only form within the slave radio thats it..

We cant turn management to work on data port as those ports are isolated from the local lan and is in essence hooked to the WAN network thats why we opted to use the management ports on the radio to hook to the lan on the far side.

Thanks
