hAP ac² LAN->WiFi 5GHz performance issue.

[nemoforum]

I’ve bought hAP ac^2, configured it and got an issue: transferring speed from LAN device (micro server with 1 Gbps eth) to Wi-Fi 5GHz device is VERY low and unstable: 0.5..2..5..20..50 Mbps, tested with two 5GHz devices with iperf3.
At the same time transferring speed from LAN device to Wi-Fi 2.4GHz device is OK: around 40..50 Mbps.
In addition:
WAN → LAN (server) = 800..900 Mbps
LAN (server) → WAN = 200..300 Mbps
WAN → Wi-Fi 5GHz (device 1) ~ 200 Mbps
Wi-Fi 5GHz (device 1) → WAN ~ 220 Mbps
WAN → Wi-Fi 5GHz (device 2) ~ 150 Mbps
Wi-Fi 5GHz (device 2) → WAN ~ 170 Mbps

For testing purposes, I’ve completely reset router’s configuration, applied default one.
I didn’t make ANY changes to the default config.
I got the same result: awful LAN->Wi-Fi-5GHz performance.

*What’s wrong with LAN (server) → Wi-Fi 5GHz (device ) ?!
When will this be fixed?

I have the same problem with hap ac2. 2.4 GHz and 5.2 GHz work poorly, speed is unstable.

[nemoforum]

@normis,
Any solution?
Should I return the router?

[poizzon]

Can you provide more detail statitic ?

1. registration table statistic : http://forum.mikrotik.com/t/mikrotik-cap-ac-performance-review/117477/22
2. registration table signal : http://forum.mikrotik.com/t/bad-wireless-reception-with-rb2011uas-2hnd-in/62979/1
3. chanel overlap http://forum.mikrotik.com/t/bad-wireless-reception-with-rb2011uas-2hnd-in/62979/1
4. speed test results
5. which equipment you are using
6. which ROS version

I’m trying test 3cAP ac, via CapsMan, and see same performance issues…

There is tests, with no changes :
Download 95.72Mbps Upload 20.40Mbps
Download 180.74Mbps Upload 152.15Mbps
Download 185.61Mbps Upload 218.71Mbps

5. Intel AC-7260, Xiaomi Redmi Note 3 Pro ( http://www.speedtest.net/result/a/3792054297 )
6. 6.42rc52

It’s not Wi-Fi link issue.
It’s LAN-WiFi 5GHz issue, because bought Laptop and Phone shows the same problem with LAN-WiFi 5GHz connection.
And there was NO the issue like described with hAP ac.

[nemoforum]

The same tests with my phone and server.



Upload speed from server is lower, because vlan is configured for internet connection, BTW why so slow?
With default ROS config speed is around 800..900 Mbps up and down (from server to internet and backward).

[nemoforum]

Hey Mikrotik! Any answer?

[poizzon]

Hey Mikrotik! Any answer?

Can you perform test with changed chanel width?

?

Also Intel 7260 slow performance :

https://communities.intel.com/thread/59726

[nemoforum]

Intel 7260 slow - ha-ha!
It works perfectly with hAP ac (I got stable 200..220 Mbps with it) and many other routers. As well as Xiaomi Redmi Note 3 works perfectly with hAP ac (on 5GHz).

The test results you asked for are below, as expected nothing changed.

We are making a decision - not to buy MikroTik, as always AP to buy Ubiquiti

It’s interesting to get feedback about FT and Unifi series..

Mikrotik,

Any official answer?

[nemoforum]

Intel ac 8260 - the same issue.

Mikrotik?

Intel ac 8260 - the same issue.

Mikrotik?

Intel ac 8260 - 2018-02-06, 20.40.0.4

[juliokato]

equipment mounted pointing up !!!with very good speed…

[poizzon]

so there is two tests, one test and after few seconds - second test.

no change, no move just chrome open new tab and repteat test

so wehere is comment from MT ?

[andriys]

Any official answer?

I’m a bit tired repeating this again and again, but…

This is a user forum. Period. Mikrotik staff may occasionally answer some questions here, but they do not have to. If you need an “official answer” you should write you question to support@. I’m afraid that’s the only “official way” to ask you questions.

andriys: as you are an official MikroTik employee, could you please raise up an idea of creation an official communication channel MikroTik → users? IMHO if everyone who has any question should write to support@ then you would not do anything else just responding to e-mails.
I (and definitely I am not the only one) think that this could be beneficial to both - MikroTik and also its users.

[jarda]

It seams the email to support is the only way, because they have a ticketing system there and maybe some people that do the filtering above that to ensure nothing will be lost and everything will be replied at least somehow. I think that such way is quite secure but not fast enough. Other ways could loose tracking. And as you see, mikrotik is able to react officially here on the forum if they wish. Unfortunately they do not wish at given time or do not know how to react many times.
