I have 9 APs and one is running at 100 mbit while the rest are running at 1000 mbit. I did not run the cable for this but it is getting power from an injector at the switch. Any ideas why this would be happening?
Is it the only device using a power injector? Could have a max speed
Is the switch port configured to run at 100?
Is it on the same switch as the other APs?
What switches are in the picture?
Check if you are negotiating any speed and the cable type.
Also check the cable length, when you are running PoE there are shorter distances than without. Is the injector by the switch or the AP?
We have a couple of APs that flip between 1Gb and 100Mb every couple of days or so, we have tested the cabling and it all seems okay. As the end users don't need more than 100Mb we haven't bothered replacing it...
I remember seeing a short black patch cable although I don't remember if its flat. I'll be sure to check that out.
Thanks CMR. Funny you should mention that. Last time I looked at the switch, I saw two devices running at 100. Now I only see one. Its a school that is closed based on the current situation so I can't see the switch but one device that was previously report 100 is now 1000. 🙄
Just for giggles, swap the AP connected 100mbit with one of the known working at 1000mbit using that same cable. See if the problem remains, follows the AP, etc.
If you know that the switch port is good, it has to be one of these -> AP, cable(s) or PoE injector.
Process of elimination to find the winner!
It doesn't have to be flat or even cheap cables, we had a batch of shielded cat6a cables that simply wouldn't run APs at 1Gb and they were 10Gb certified 😂
For 1 GB Cat5e is enough 🙂 Cat 6A and higher is best for storage like Avid Nexis where you need high throughput. You don't get any benefits from using cables with higher category.
I would agree with Cat6a vs 6 and at a push a shielded cat5e is okay, but it does depend on your environment, as our buildings approach 100m end to end cable runs and we cannot control power cables being placed near them in ceiling voids or under floors, shielding and the more copper you have the better! We did run 100Mb over Type 1 for years with impedance adapters, now that was good cabling 😎
So i suggest using fibre instead of copper between the farest locations 🙂
