Super slow WiFi speed on default configuration

Sat Feb 22, 2020 1:19 pm

Hey all.

Can please someone help me understand what could be the problem in my simple configuration, when my WiFi is incredibly slow?
Came to a point of replacing home router to Mikrotik RB2011uias-2hnd-in (RouterOS v6.46.3 (stable)).
Did a factory configuration reset and have just set SSID and WEB2 password for WiFi.

Provider promises 100 Mbit/s.

My LAN ubuntu server (using speedtest-cli) shows:
Hosted by KeFF Networks (Kista) [4.78 km]: 2.076 ms
Testing download speed.........................................................a.......................
Download: 95.84 Mbit/s
Testing upload speed......................................................................................................
Upload: 2.93 Mbit/s
Which is promising :wink:

My WiFi ubuntu laptop (using speedtest-cli) on a distance on 4m from router shows:
Hosted by Tele2 (Kista) [4.71 km]: 9.398 ms
Testing download speed................................................................................
Download: 36.59 Mbit/s
Testing upload speed......................................................................................................
Upload: 3.64 Mbit/s
Which is 3 times slower :o :shock:

While my iPhone 7+ (using speedtest iOS app) on a distance on 4m from router shows:
Download - 18.1 Mbit/s
Upload - 9.41 Mbit/s

And friend's Galaxy S10+ (using speedtest Android app) same 4m distance gives:
Download- 33.3 Mbit/s
Upload - 7.62 Mbit/s

Can someone please help me to understand the bottleneck and how do I properly make a home network?
My goal is to have a stable WiFi in apartment(3 rooms apartment) with about max 10-15 devices connected simultaneously (a few phones, laptops, and Philips smart bulbs)

Here is my Mikrotik config export:

Default wireless configuration is like not really optimized...

To get best performance:

- use 20MHz bandwidth
- choose channel manually, either 2412/2437/2462 (perform a scan to get least used channel)
- set encryption on aes-ccm

Besides...what are you expecting? And what made you choose the RB2011 (with 2G only)?

Thank you for your answer and help, @erlinder.

I have put all suggested optimizations, but it didn't seem to change much.
My expectation would be to get 90+ mbps/s on WiFi, when operator promises 100 mbps/s on cable. Is that a realistic expectation at all?
By “2G only” you mean the router with 2GHz alone? Honestly, I didn’t have much choice when getting it, but I was aware that I would want to add 5GHz band, so my idea was to get a more less powerful “core”(RB2011) and then add an access point which would support 5GHz down the road

Hi. Did you ever figure this out? I'm sitting in the same boat at the moment.

I think the conclusion not to expect too much wirelessly of this device as it is 2.4GHz only answers your question...

I had the same issue... resulted in me sending the device back for a refund.

Hi guys, it seems to be a good performance for a 2.4Ghz WiFi. If need fly faster you should buy a RB with 5Ghz antenna.

By other hand the default WiFi config it's not working well for me. I'm just getting 10Mbps on 2.4 WiFi. Really bad!!

Limiting AMSDU to 2048 I get a non stable improvement on performance.

MT's non wave2 WiFi sucks but it's also true that you can't get fast 2.4GHz if you are on a crowded environment. When I was living on the suburbs I used to get 100-110Mbps with an old router on 2.4GHz (20MHz) using a 2x2 client but on the city I can only get 70Mbps at best using OpenWrt or 25Mbps with ROS on hAP ac2, 5GHz is fast on both but ROS WiFi has always been unreliable for me.

I am have this same issue. My ISP service (Spectrum) is 200/10 and on a wired connection I can get that. Wireless connections 2 or 5 were running around 10. I'm running the default MikroTik script with very few modifications.

I found in my Audience that my 2GHz band was set to 2GHz-B and my 5GHz band was set to 5GHz-A. Once I changed those to 2GHz-G/B/N and 5GHz-A/N/AC my performance increased to to about 50 on the 5Ghz and 30 on the 2GHz. These numbers are still piss poor. I have lots of 2.4GHz items in the house, who doesn't, network should still run better then that even when crowded. I installed a Plasma-Cloud PA2200 a while back as a quick test and got screaming speeds on both channels. I don't remember what the speeds were I just figured I needed to spend some time configuring the MikroTik.

I have installed these Audience devices in other locations and had great success.
