AP55 and APX120 performance differences

Do you use 5 GHz with 80 MHz Band? 

Hi,

yes I do.

Ian

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.

Ian

Any chance to try another apx120?

I have two and tried both.

Ian

My point is, APX120 is a wave 2 Accesspoint. If somehow the negotiation seems to fail and the client select only to send 40 MHz, this will limit you to this number. Are there tools to check the current channel selected plus the used bandwidth on your devices? 

I dont think that its the issue...APX740 are also wave2 and all my not wave2 devices are connecting at 866Mbit, and those APX are managed by "older" UTM with manually set 80Mhz via console, as it cant be set in WebAdmin

Hi folks,

this morning I changed the mac-mini (2020 intel) to using wifi.

The results are

1/. channel 149

2/. TX rate 433

3/. 802.11ac

4/. connection bandwidth 80mhz on 5ghz SSID.

I disabled the APX120 and so the mac mini is connected through the AP55 and immediately showed 760mb/s connections speed.

What else do I need to do to prove there is a bug in the APX120 firmware?

Ian

Register a Sophos Wireless Trial in Central, plug in this APX to Central and check, if there is a difference in this firmware.

Brand new mac-air connects to the APX120 at 433 and to the AP55 at 760.

Is it a bug and if so when is it likely to be addressed?

Hi folks,

I think have identified part of the cause of the issue, the APX software does not appear to select the 80mhz channels even though 80mhz is specified in the configuration. I will manually change the channel to one of the 80mhz channels and see what happen.

Ian

Hi folks,

a little fuel on the fire.

Today I purchased a Ubiquiti Unifi l6 and installed it on my network.

Results of 6 APs

1/. AP55 coonects at 866mhz

2/. AP55 connects at 866mhz

3/. AP55c connects at 866mhz

4/. Unifi L6 connects at 866mhz

5/. APX120 connects at 433mhz

6/. APX120 conencts at 433mhz.

So to me that this series of tests indicate there is a problem with the APX firmware.

Now just need a dev to agree and fix the issue.

Ian

An extra benefit is I get at least 150mbs on my 2.4ghz SSids again. I can’t remember when that speed connection went missing from my network.
