hAP ac 2GHz speed 10Mbits

RouterOS Wireless Networking

Hello

I have speed issues with my 2GHz network. Also, my Android phone does not see 5GHz network.
I have already checked other branches on the forum. When I disabled the “fast track” rule, 5GHz speed increased 20Mbps → 80-100 Mbps.
2GHz remains dramatically slow. Seems there is some misconfiguration.
Could someone give me a hint?


Config:
I use two networks: my main network, where my private devices and iOT are connected, and a separate network for guests. Now, there is not much difference, because the config is not stable. But I use ACL in my private network.

I connected to the Vodafone modem/router. Hence, using DHCP on Mikrotik.
From time to time I get " network changed" error in Chrome for some reason. Not sure if this is because of Mikrotik.

Current speed test:
2GHz: download: 9.83, upload: 0.08 Mbp;
5GHz: download: 100.0 Mbps, upload: 23.9 Mbps;
Cable connection: 100.0 Mbps, Mbps; 80 Mbps;

Full config attached.

Are there any ideas on how could I improve my config?

Thanks!

There are some improvements to make:

  • don’t use auto channel
  • set 2.4GHz channel-width to 20MHz
  • set country code
  • don’t use legacy protocols
  • don’t use superchannel

Hope this gives some improvements.

Thanks for the suggestions, erlinden.
I applied everything you referred to. What do you mean by “legacy protocol”? Did you point 802.11b? I still have one smart socket with this standard =(.
Tested network after all these changes. Does not bring any improvement. 2GHz wifi still has 5-10Mbps. Although signal is displayed as “excellent”.

Some more ideas?

try different frequencies, start with lowest one, then highest one, see if it makes any difference.
try to set 2GHz-onlyN

Socket will not work for a moment, but you will be able to rule out that protocol is the issue

Can you share your adjusted config as well as an overview on the registrations:

/interface/wireless/registration-table/print

This will give an overview of all clients registered to the hAP ac.

Thanks for the response.

I tried wifi G/N, and also tested all available channels. Speed fluctuates a bit, but no significant improvements (no higher 10 Mbps).

Maybe it’s hardware fault ?

Could be wireless saturation, especially when using legacy devices. You can test with only a single device connected, just to make sure that the radio isn’t the problem. Because currently the links are at low speeds. Additionally, do some testing with different channels (2412, 2437, 2462) as @normis mentioned.

In addition (but that is not the problem you are aware of) you might want to consider using VLANs instead of multi bridge:

Thanks @erlinden!
I have already tested all available channels. No improvements so far.
I will try to look into vlan and keep you updated.
About wifi saturation. Well, 20-30 devices should not be a problem for this model even for wifi4. Am I right?
Could it be related to an issue, that I have a “network changed” error in Chrome? Maybe, I did something wrong with Nat?
Well… Then, I should have speed issues on all networks.

Honestly, I am thinking about updating to ax3. But the only benefit there is Wi-Fi6. hAP ac looks better from CPU, and RAM.

You know, maybe if you start from the beginning ? Save your config, restore default configuration and then see if problem persists, if not, make config changes and monitor situation after every change, maybe that way you can narrow down the problem ?
