AP55 and APX120 performance differences

Do you use 5 GHz with 80 MHz Band? 

Hi,

yes I do.

Ian

Can you try to recreate your Wireless Network, if this will resolve something? 

I will swap them around, one only uses the 2.4ghz channels.

This has been an issue sine I installed them to replace the AP55s with the same setup.

Ian

Hi,

swapped the devices between networks after disabling the groups. All devices back online still showing the same connection speeds. W10 after a power off and on is 412mb/s.

Ian

As far as i know, windows uses the channel width and calculate the max speed based on this. Seems like its stuck by 20 MHz, not 80. 

Which Channel do you use? 

I use auto channel configured for 80 Mhz. With the AP55s the same W10 connects at 866 Mhz, so did the Apple devices.

Hi,

here are a couple of screenshots, the first is from the APX120 and the second from an AP55.

Interesting observation, the Apple devices drop connection speed on the AP55 when idle, but on the APX120 they don't. SO that to me indicates that the APX120 is running a newer version of the WIFI standard that makes the Apple devices much happier.

I think the above screenshots make the issue very clear.

Just to 10c more, the devices on the 2,4ghz SSID used to be able to connect at 72 or 144mb/s now can only connect at 68mb/s.

Ian

2.4 is set to 40Mhz channel?

Hi,

yes, they are.

Ian

Have a look if network card driver supports to force connection speed, some cards do, if it does, rry to force it somewhere up from 72Mbit, just to test if it connects

Hi,

thank you for your thoughts on the subject. It is not just one device it is any device that connects the 2.4ghz SSID on the APX120.

Tomorrow, I will do a temporary network re-arrangement so I can have the APX120 and the AP55 on line at the same time so I cn the screenshots and post.

Ian

Here is the AP55 2.4ghz SSID bandwidth connections.

I will update this post with the APX120 2.4ghz SSID connections shortly.

Well...true is, that it is 40Mhz, as it will not go over 72Mbit on 20Mhz, but i dont understand that drop...

What about 5Ghz, that works fine or is the same problem?

Just to be sure, are we talking about Performance differences in "speedtest numbers" or only those "shown numbers on Client/XG"? 

Those are different issues. 

Another test would be to move to other channels and check if the connection is better. 

Hi folks,

they are performance numbers shown by XG against client connections. The channel numbers have no affect on the results displayed.

I will try the speediest between various computers and see what I can achieve.

Ian

Hi folks,

I give up, the speed tests are difficult to run and fail to provide any meaningful results with the W10 PCs.

Ian

Hi folks,

some new information. I bought a mac-air and connected it to the wifi for updates. Maximum connect speed shown on the XG using the APX120 is 412mb/s. 

Ian

Not much... with ap55 Mac connects 866?

Can you select on the Client, if you want to connect to 40 or 80 MHz? Sounds like your 5 GHz is only connecting to 40 Mhz. 

This only an issue with the APX120, the AP55 and AP55c all show 866.

The issue is not client dependent eg iPhones, iPad, MBP, mac mini, w10, and mac air (2020 M1) all have the same issue when connected using the APX120.

Common item - APX120.
