Poor wireless Speeds on RB4011iGS+5HacQ2HnD-IN

Tue May 25, 2021 4:27 pm

Hi all,

I've recently had an RB4011iGS delivered and have installed it on my home network but have noticed that my WiFi network speeds have decreased by up to 300Mbps on 5Ghz. My network is a residential 1Gbps line provided by Virgin Media, UK based, and the modem is set to modem only mode with a bridged connection on the router. Ethernet speeds are 1Gbps as expected.

Disclaimer: I am by no means a networking expert and it has been almost 10 years since I last studied networking in college. I purchased this router to study some network concepts again.

I have configured the router using the easy setup wizard which, I understand, the system picks generic settings which may not match my requirements.

I would appreciate anybody's time with this one.

This is the configuration from the router.

Re: Poor wireless Speeds on RB4011iGS+5HacQ2HnD-IN  [SOLVED]

Wed May 26, 2021 7:55 pm

I've spent the past day looking into this and have made many adjustments to the frequency, channels and other various settings based on my country-info
5170-5250/a,an20,an40,ac20,ac40,ac80,ac160,ac80+80(20dBm)/passive,indoor
5250-5330/a,an20,an40,ac20,ac40,ac80,ac160,ac80+80(23dBm)/dfs,passive
5490-5730/a,an20,an40,ac20,ac40,ac80,ac160,ac80+80(27dBm)/dfs,passive
5735-5835/a,an20,an40,ac20,ac40,ac80,ac160,ac80+80(20dBm)/dfs,passive,outdoor
5190-5310/a-turbo(20dBm)/dfs
5180-5300/a-turbo(20dBm)/dfs
5520-5680/a-turbo(27dBm)/dfs,passive
5510-5670/a-turbo(27dBm)/dfs,passive
2402-2482/b,g,gn20,gn40(20dBm)
2417-2457/g-turbo(20dBm)
902-927/b,g,g-turbo,gn20,gn40(30dBm)
I've also attempted to match the settings of my ASUS router
5GHz N/AC
20/40/80MHz Ceee
5220
I have been unable to get anything close to the 300-400Mbit I expect on my devices, which I am getting via the ASUS router as an Access Point. This router delivers, at best, 100Mbit and is very inconsistent at doing so.

At this point I think the wireless capabilities simply aren't that good for the RB4011iGS+5HacQ2HnD and so I have reported this unit as faulty and requested an exchange, with the supplier, for the non-WiFi version.

5220 should be 20/40/80MHz eeCe, Ceee is wrong, if you want to use Ceee then you should use it with 5180. For easy to understand, kindly follow:
5180 Ceee
5200 eCee
5220 eeCe
5240 eeeC

Thank you for this list. Is there somewhere that I can find this information for all frequencies?

I did try to mirror the config from my ASUS router only in an attempt to get as close as possible to a configuration that works. It's possible I got the 5220 mixed up.
I have also used 20/40/80-XXXX, as suggested here on the forums, but have had little luck in getting any faster speeds. The coverage itself is quite low as my TV, roughly 10-15 steps away from both routers, is unable to pick up the SSIDs, which I believe is causing the slow speeds as I get further from the router.

Realistically you should expect speeds on 5Ghz with LOS, in the range of 1733/3 = 575Mbps and for 2.4Ghz around 100Mbps.
2.4ghz will work reliably through one wall and okay through 2.
5ghz will work okay through one wall

I am beginning to think that my expectations with the WiFi driver on this router are unrealistic. What I don't understand, in my naivety, is how the ASUS router can provide a better signal than a more quality built router. On second thought, I know the ASUS uses the Broadcom BCM4366E which I assume performs better than the QCA9984.

I think the best choice here is to continue to use my RT-AC86U as an access point.

There is no need to set installation=indoor - that setting is for scenarios where you want to avoid interference with wireless ISPs in rural areas that use 5ghz. If you have standard residential service that isn't provided over wireless, setting installation=indoor will just artificially limit the frequencies that it has available to choose from, for no benefit.

That was initially as per the default config. Changing this at various points didn't bring much, if any, increase in signal or speed.

On my capac I have a setting of
5GHz - N/AC
20/40 MHz Ce

Give that a shot,
(freq used 5540)

Installation: ANY
WPS mode: disabled
skip DFS Channels: ALL
WDS mode disabled (this is on a different tab selection)

I can't find any document regarding this too, but it's actually very easy to understand, for example 5180 is channel 36, if you use 80MHz wide means channel 36 is control channel, and 40/44/48 is extended channels, the correct setting is 5180(36) 20/40/80MHz Ceee, if you prefer channel 44 (5220) then you should tell the system to use 5220 as the control channel by setting it as 5220(44) 20/40/80MHz eeCe. You previous setting is 5220(44) 20/40/80MHz Ceee and the system will make it like 44 as control channel and 48/52/56 as extended channel, this is non-standard setting and make you devices confuse, that's why you will see a very low performance in Wi-Fi.

Btw don't use 20/40/80MHz XXXX due to sometimes MT will make the same mistake as you did before, offering something like 5200 20/40/80MHz Ceee which is wrong, MT should take the blame on this.

True, AC86U has much better Wi-Fi performance than RB4011, just turn the Wi-Fi off in RB4011 and use AC86U as AP, this will save your time. There are no magic setting to turn MT Wi-Fi to match
any other Wi-Fi offered by other vendors, the problem is causes by Mt's driver not setting. The latest development 7.1beta6 has a better driver, you may try it if you wish to get more from RB4011 Wi-Fi.

Thank you for sharing this information in both of your replies. I did follow the advice from the 3 recent messages but have still had no luck in having a better signal. For now I am throwing in the towel as I can see that WiFi isn't MT's strong point. Still patiently waiting to hear about an exchange for the RB4011iGS+RM.

You will not find better value than Mikrotik routers, so the right purchase is the RB4011 without wifi.
Getting a combo router is not usually recommended because ideal wifi locations are rarely optimized where the router is located.
Further wifi technologies change at a faster rate and a good router will last much longer.
If you are looking for a solid wifi5 access point I have had success with the TPLink EAP245.
They make wifi 6 access points 620, 660 but have not tried those yet.
THe other end of the scale there is rukus meant for heavy duty use with many users and pay through the nose, but you get top performance.

For the meantime I'll stick with the AC86U as I'm in a rented 1 bed apartment with my missus so, unfortunately, I can't do too much drilling or wiring and the coverage area isn't so big. I will check the TPLink WiFi6 products out as I can fit this into a house plan.

Thank you all for your assistance.
