@Philbert Hi, I can confirm that these results are with with fixed 80MHz channel width. I have both tried with some minor tweaks like disabling CCK rates and with stock settings after deleting and adding the wireless LAN again. Under site setting the only changes I have made is to disable mesh and enable band steering, no Airtime fairness etc. 

 

I have also tried to downgrade to 5.0.1 with the same results and I'm now back at 5.0.3.

 

Iperf results from the server that has been confirmed by wired tests to be able to provide Gigabit speeds. These results are with 8 other clients attached but very little traffic.I could move the clients to another AP but I'm quite sure that will not change anything. 

 

 

As I said the Mikrotik is getting the speeds one would expect so I'm quite surprised to see such poor results on the EAP. It could be a hardware issue perhaps but any suggestions on configuration mistakes or possible solutions are welcome.

This test is on a Mikrotik Wap ac ap, MCS 866. Same placement as the EAP and quite different results.

I take back I'll my critisism of the EAP254, I finally found the error...

The problem was the patch cables. It appears that with short 50cm cables I can reproduce the same poor results again and again. I have two similar short cables and get poor speed with both. But changing the patchcable to another longer one (1m) fixes the problem and I can get full speed. The same error occurs both with direct POE connection and using the injector too. There were no frame errors counted on the switch and the port was connected at 1Gbit so this was a little hard to diagnose. I guess you should always look closely at layer 1 first... :-) 

 

Not the easiest issue to find but I'm glad I got there in the end. 

 

Much better than Mikrotik too, this is the EAP245 now:

@MarkB 

 

MarkB   How are you getting on?  did you get some IPerf tests completed or any other information?

 

@Philbert 

 

Hello Plilbert,

 

I test at this time with de bandwith on 80 mhz on the 5 ghz. 2.4 ghz on auto. maybe that will be a solution. 

I think you can also try different cables. Sounds a good idea. Backblast has resolved the issue by changing the patch cable.

@Philbert 

 

How do you have DFS enabled on your 245 HD ?

@AndreMartins 

 

Hey

 

Yes I do indeed

 

The area I live in has high traffic on 36-48 so my APs are all on the DFS channels, 64 and 108 to be percise

 

Speed wise, noticable.  They get around 450mbps on DFS, drops to around 350mbps on 36-48 (non DFS) using a 2x2 card

@Philbert 

 

My point was, it doesn't appear to me at all.

 

I'm having issues with coverage and performance with 4 EAP245 and one AC88U from ASUS.

 

If I don't use them all, seems to not cover everything in the house, which have a lot of brick walls and 4 levels.

 

But the DFS is not showing up. I'm using 5.0.3 as firmware, 4.4.4 at the Omada Controller sw and my EAP is the US version

@AndreMartins 

 

Umm thats strange

Im guessing you are going into them via    DEVICES >   CONFIG    RADIOS

 

 

Unless its something to do with the US version, im on EU version running 5.0.3 but i have had DFS for a long time now
