Sir,
Please if anyone can help that will be fine. My CTO is not in town and I have some customers who called in to report that the internet at their premises is way too slow, considering the speed they are on => 10Mbps running on 20MHz, distance is 3Km.
CPE => E-force 180
AP => ePMP1000 (90degree)
The link quality and link capacity keeps dropping from 20% to 10 and later go to 50%, I have attached an image below for advise.
Although all AP is connected to a Netonix PoE switch
You have a problem with Received Signal Strength Indicator RSSI
50–60db good
60–65 db acceptable
65–70db weak
There is interference, obstruction, or hardware malfunction. A problem with the electronic board -10db
Thanks, sir please one more thing, Can you help me with a video or share with me a link that I can use to identify when there is an interference on the link.
From all that you highlighted, it seems the interference, and hardware could be the cause I noticed customer calls to complain, although not every time, but sometimes that the internet is so slow. and their link quality and capacity keep dropping.
I don’t know how to put this to my CTO if we should observe with one AP, connected directly to a PoE, Let’s isolate with that and see if the link improves.
Regards,
Joseph
Check network cable as well. It should be 1000mbps (ethernet cable)
You are right sir, Sorry my picture above look misleading, the picture is gotten from the customer’s radio, and the router attached to the radio is in 100Mbps
A chain is only as strong as its weaker link.
And in your case, it doesn’t matter if the radio is able to pass 100 Mbps throughput, it will never pass more than anything in the series.
“A chain is only as strong as its weaker link”.
Very low RSSI.
If there’s only one customer with than (bad) signal, could be its CPE that has moved since installation. If all the customers have the same problem could be your AP.
10 Mbps to the Internet is not good at all, there is no bandwidth.
We once had a problem with a client who was !touched! lightning strike, everyone else on that AP was bothering us until we recognized it and replaced it, there were a total of 12 clients.
He, like the others, did not give usable results at all on the wireless link test. After replacing the problematic one, everything worked as it should.
Reboot one client and wireless link test on the other, there is enough time for that while the rebooted one is booting. in the meantime and so on until the last one.
Show us what the Spectrum Analyzer shows.
You can check how-to in user guide.
I must say a very big thanks to you all, you all are amazing with the brilliant ideas you gave me.
God bless you all
Many Thanks
Joseph
All customers on the AP are having the same issue of poor throughput, am feeling it could be power related. All AP and PTP are connected to a Netonix PoE switch and the server room is a bit hot, Don’t know if that could contribute to the cause of it. before now we used the PoE that comes with the cambium device, but my CTO have to change that to a Netonix PoE switch.
Ok thanks for your contribution, the image shown above is from the CPE, not AP and all customers are having same issue.
The POE power supply is not the problem.
When POE is the problem, the device usually reboots or won’t start.
Power supply with POE can be any unstabilized source, it is important that it has between 40-56 V (perhaps a larger range) and enough energy. The AP itself has a step-down converter that converts the POE voltage to a brutally stabilized 5V and from it another 3.3V, etc.
Look for the problem elsewhere!
Interferences in the ether or one of the clients spinning the traffic in a loop and complicating the conditions for the others.
I have already written how to detect the client causing the problem, everything is easier than going to all the addresses with the problem.

Hello Joseph,
You need to log to the sector this SM is connected to and look for a better frequency. You are better off with something in the 5.4 range, 5.7 range or 5.8 range. Also, since this is an SM, you need to get 100Mbps on the cable. 10mbps is no good. Cable MUST be crimped again to achieve this.
Ok Zica49, But we have a Netonix PoE switch, of which I’m thinking might be the cause, maybe not supplying enough power the the AP… my thought!!!
Many Thanks
You are right on the cable part, I feel it should be power related, that’s my thought though! But we will look at the interference part also.
Many Thanks
Joseph
this is not switch related. I have seen this many times.
It might not be interference related too.
It might just be that the location of the SM does not allow the connection on that frequency to be maximised.
The connection of that particular screen is not POE related.
The LAN side from the POE to the router is what is showing 10mbps.
Its either you need to so alignment of the ratio to get a better throughput or change the frequency to achieve the speed desired after getting rid of the 10mbps.
Go on the AP this SM is connected to.
Login
click on Tools
click on Automatic Channel selection
Toggle to enable
Click save at the top
Then click RUN ACS
wait for the output - leave that screen on - it will show you the frequencies
I tend to avoid channels lower that 5.4 zone - l like anything between 5.40 to 5.85 that has zero or one interference.
Write down your choices
Go back to configuration, disable automatic frequency selection
choose the choice that you concluded on
Save it and test.
How to test.
Log into the SM
Go to tools and choose Wireless Link test and run test
You will see the maximum throughput that that SM will get.
Thats it
