I have noticed that my Mi A2 does not show full speed on wifi.
I have a 100 Mbps connection, which when I connect via my laptop clocks at around 92+ Mbps, but on my A2 it only clocks about 50 Mbps.

Check which type of wifi your router can provide.
From Wikipedia : There are many different versions of Wi-Fi: 802.11a, 802.11b, 802.11g, 802.11n (Wi-Fi 4[40]), 802.11h, 802.11i, 802.11-2007, 802.11-2012, 802.11ac (Wi-Fi 5[40]), 802.11ad, 802.11af, 802.11-2016, 802.11ah, 802.11ai, 802.11aj, 802.11aq, 802.11ax (Wi-Fi 6[40]), 802.11ay.
One of the most popular wifi norm used over the years is the 802.11.g, which is capped at 54 Mbps. Could be an answer.

Just tested at home.
I have a 350 Mbps connection. I get 120 Mbps in download, and 40 Mbps in upload. (can't post pic)
I think my router must use 802.11ad, but I'd have to check.
---------- Post added at 06:53 PM ---------- Previous post was at 06:48 PM ----------
Back again, made more tests.
Be sure to connect to a 5 GHz band. My router can use 2.4 GHz and 5 GHz bands.
I'm getting way worse results on the 2.4 band. So use the 5 GHz if you can.

Either its using 40mhz channel bandwidth (144mbps per "antena") or it has dual antenas (2x 72mbps at 20mhz or 2x 144mbps aka 300mbps at 40mhz).
Mi A2 only has one for 2.4ghz (72mbps at 20mhz or 144 at 40mhz) and one for 5ghz (433mbps at 40mhz and 200ish mbps at 20mhz if im not mistaken)

So I should force my router to use 40Mhz band? What other settings should I be using? I also have a WiFi Range extender, not sure if that supports using different bands.

40mhz is a bad ideia for 2.4GHz since to do it it overlaps channels wich most probably are already in use around you.
on my Mi A2 on 2.4ghz i always get around 50mbps (72 minus overhead) which seems just fine. The phone is fine.
on 5GHz i get my 200mbps.... your laptop probably has MIMO technologie
Ok thank you for the explanation, I'll just upgrade my router, and probably check if I still need the range extender, then maybe upgrade that too
Check your wireless AP? Or try it with another AP?
All redmi phone only getting 50mbps on 802.11n on 2.4GHz
All redmi phone only getting 50mbps on 802.11n on 2.4GHz i have test. I have redmi note 7 pro latest and a Realme note 5 pro and a laptop, my wifi connection is 75mbps. When i test the speed then in Redmi note 7 pro is always getting 50mbps or below it cannot goes beyond 50mbps but in Realme 5 pro and in my laptop both are getting full speed around 72mbps..
Therefore you all have not any issue with your wifi router the problem is only in your Mi devices....
If you don't trust then check and compare the speed with any mobile and u will get to know the Mi devices is only limited to 50mbps.
I know that i have a alternative option , if i use 5Ghz router and my redmi note 7 pro also support 5GHz but my question is why Mi devices are failed to getting speed on 2.4GHz where all others brand are getting 802.11n speed.
I don't want to get alternative if anyone has the solution then post here otherwise we know the alternative so pls do provide alternative option.

You are not entirely correct. Maybe it is a Redmi throttle because on my Mi X6 my speed runs to around 100Mbps on 2.4Ghz and reaches around 350Mbps on my 5Ghz connection . My internet connection is a 1000Mbps connection but I only achieve that speed on my computer with gigabit ethernet and cat5 cabled connection. Never by WiFi .

Agreee. I have a Xiami MI A2 and I used to get +70 Mbps in 2.4 Ghz and +150 Mbps in 5 Ghz. A couple of days ago I had issues with my router and had to restart it and now I can´t get more than 30 Mbps in both 2.4 and 5 Ghz... but I also got the March security update in the phone so not sure what´s causing the issue. I´m quite sure it´s the phone because other devices perform fine in the network.
you can solve the WiFi speed by using custom kernel Agni for example. Try the different libs to see which work best . But so yes Xiaomi throttled WiFi in newer versions ..custom kernel like agni gives option in aroma to choose another modified or older lib . This will double your speed .

Hey sorry to bump a thread like this, but it seems it's not an issue many persist with as most internet connections are usually below 50Mbps so users don't notice the issue.
I've got a new Redmi Note 11, and along with an old Redmi Note 8 I have, both have limited WiFi speeds on both 2.4G and 5G networks at 48Mbps for some reason.
Your claim that Xiaomi throttled the WiFi in newer versions makes the most sense, so I have a question if you don't mind. Would just going for the latest Agni kernel do for me? I'll be trying to port TWRP to this new phone and see if I can flash the newest Agni, from there is there anything more to do? Will the WiFi speed be back to normal?

hmm.. mine doesn't see the 5GHz radio on my Netgear WNDR3700.
Weird.
As a side note, i do think connecting to the 2.4GHz radio is a better idea as it has better range, and the Note won't be able to utilize the extra speed of the 5GHz channel anyway.
yes it works 5.0ghz also, with d-link routers.
its faster than on the 2.4 crowded band.
Mine connects to the 5 Ghz coming out of my WRT610N running dd-wrt
Works fine on my old Belkin G router (2.4Ghz) and the new Belkin N router (5.0Ghz). So yep.

The note has only antenna, so yes, it won't fully utilize it, but I get much faster speeds on the N router than the G oh and the speed drop off at the edges of reception is much less with N.
Hmm, well my 5ghz doesn't seem to be showing up. Anyone have any idea what troubleshooting steps I should take?
---------- Post added at 11:52 PM ---------- Previous post was at 11:38 PM ----------
So just an update for people. I figured out the issue. 5ghz doesn't seem to be supported on 1xx channels, but works just fine on the lower frequency xx channels. I wonder, is this an European thing? Would there be a firmware tweak to enable the higher frequency (and higher output power) 1xx channels?
+1 on that. I would like to see it able to be used with the higher channels
I think it depends on whether the router utilizes the 20MHz or the 40MHz band. I bet the note can only see the 20MHz one.

OK ppl its the channel your router has set for 5ghz. European basebands only see 5ghz channels provisioned on Europe. Check Wikipedia, specifically here: http://en.m.wikipedia.org/wiki/List_of_WLAN_channels
Simple fix... change router 5ghz channel to match region of your baseband
Using a higher or lower channel means nothing. Its finding the channel that is least crowded and has the least amount of interference.
Worked!

I wasn't able to connect with my netgear wndr4500, but this fixed it! thanks!
Or you can always flash a firmware which supports your local 5 GHZ frequency in case you have other devices which use this frequency range. I noticed that Asian firmware supports NA 5 GHZ frequencies.
I have a Linksys E4200. I tried using WiFi analyzer and put it to scan for the exact frequencies available in the E4200 5Ghz configuration, the S2 is unable to detect any 5Ghz channels. I also tried selecting all channels, but it did not work.
EDIT: Just found an answer on another thread that worked, I manually set the channel to 36. The phone immediately detected the network. Its odd that in auto the phone cant detect it.
Wondering if there is anything that can be done to get a Nook to connect at faster than 54 mbps G speeds? Does it really have a N wireless chip? I have searched and searched and cant find an answer to this.
According to the spec sheet, the wireless radio chip does support N. I'm not sure whether the software supports it
Radio: Chip ID Ti wl1271 (kernel reports wl1273) Chip supports bluetooth transmit/recieve and fm radio functions through the same antenna, but is not enabled in software drivers. Connectivity: 802.11b/g/n Security: WEP/WPA/WPA2/802.1x Mode: Infrastructure

I get N connectivity via CM7 - been so long since I ran stock that I don't recall.

Yamadog, do you currently have a n router that you are trying to connect too?
I've read before that the Nook Color wifi chip only supports 2.4 GHz range (which is used for both 11g and 11n) but not 5 GHz range (which is only for 11n). If you have a b/g/n/ router running in compatibility mode for all three types then it might possibly be doing 11n only at 5 GHz and 11b/g only at 2.4 GHz and so your Nook would never be able to see the 11n signal. Try putting your router in 11n-only mode and see what happens
I'm on CM7 and I've never seen a rate above 54mbps regardless of N availability.

I have no problem with the connection its just it connects at only 54 mbps which limits download speeds to around 11 mbps Max. My computers connect at 270 to300 mbps at download at my full 24 mbps speeds. I did have a g only router and it limited my computers to only 11 mbps like the nook. Aipparently the g rating of 54 mbps is just under ideal lab conditions and not really obtainable.
According to my home N router, the Nook Color connects at 54mbps but N is in use. For some reason that is the max rate it will use. I've seen this happen with other N devices when WMM is disabled on the client.
Whoa sorry never really answered you. My router is a cheapo 2.4 ghz n but it does allow 300 mbps connections. I have to run it in b,g,n mode because our wii is only g wifi.

I checked and did not have WMM enabled on my router. Enabled and although the connection speed still says 54 mbps, I recorded much higher, sometimes double, the download speed vs WMM turned off. Thanks! It might be a fluke but the speeds were not far off my desktop.
Actually it is a fluke. All along I have been using the android app for speed test to check my nook and it shows roughly half the speed vs the regular desktop speed page of speed test. Oh well at least I know I'm getting all the speed out of it.
fyi the Wifi chip is capable of up to 65mbps. I've seen this rate from other tablets with TI WLAN chips on my router. I haven't a clue why the Nook Color won't go that high. Not on any N router I've connected to.
I even took a look at the tiwlan.ini file but I don't see anything apparent in there. N appears to be enabled.
So my wi-fi speed was awfully slow on my razr I, I started diggin on the settings and I managed to improve it a bit by changing the channels on the router, but still, compared to my desktop pc, and my friend Iphone 4s, I only get half the speed!! (12bmps vs 6bmps), I'm the only one with this issue? any idea how to improve it? I'm on stock 4.1.2 retail br.
I get 10/1Mbps when using my Razr (tested using "Speedtest" app) and 30/1Mbps when using my laptop. They are both connected using Wifi and are in the same location. Sadly, I can not tell you how other smartphones perform in my environment.

I've made another observation. My wlan ap shows a gross bit rate of 72 Mbit/s for my razr and of 130 Mbit/s for my laptop.
It (kind of) reflects the relative performance difference I get when comparing the devices - so maybe the Razr just has a bad antenna?

I have the bad feeling that the Ri is at least capable of the "n" Standard

I just tested, set mode to "n" only, my razr can't connect, its like it tries, and then it fails and it goes like this foreverm and by looking at the iw manpage, when ti connects it looks like it connects in "legacy mode"

yeah me too, but didn't found anything, except for the above and this, maybe its a bug in my router that makes the phone fall in that legacy mode, dunno.
i have a little update:
- Razr i is indeed MIMO capable (11n standard), but can only use one paralell data-stream (1T1R = 1 transmitter 1 receiver).
That means it realy can have up to 150Mbits in a 40Mhz Bandwidth network.
can only use one paralell data-stream (1T1R = 1 transmitter 1 receiver) with 20Mhz Channels = 75Mbits max.
BUT:
- The newer 11n standard not allows to manually select 40Mhz Bandwidth in a 2,4Ghz Network
(There are some older "N-Draft" router that allows manually selection of 40Mhz Bandwidth in a 2,4Ghz Network)
The newer 11n standard only allows 40Mhz in a 2,4Ghz Network in "Auto Channel Mode" together with 6 free Channels in a row.
In a 5Ghz network it is allowed to use 40Mhz manually because there are much more channels to use...
So on newer router with 2,4Ghz and 20Mhz Bandwidth network you will have max. 68Mbits brutto (= ca. 5 Megabyte/s netto).
Maybe you could get an older n-Draft router to test, or play with the 5Ghz setting?
Just check if your Router is able to set up 40Mhz Channels in a 2,4/5Ghz network...

well, my router allows me to use 40mhz in a 2,4Ghz network, but the problem remains, also it doesn't let me use the 5ghz band, still 5 m.bytes netto should be more than enough for my 10mbits internet connection, I guess I need to try on another router, or get more feedback from other users.
Can you try renaming your 5Ghz Network to an other name than the 2,4Ghz Network!?
I have something read about that this could be a problem...

it doesn't even have a 5ghz band lol, I'm going to try to measure the local speed, maybe there is an issue else where....
edit: nop, I get almost the same speed albeit a little faster (8/10mbits)
I have had halved speed if I have tried it on a special app for measuring connection speed, but I have the same speed as on my PC if I use browser and it tests on my razr I.

where do you test it? (don't tell me it feels equally fast)
I am facing a slow speed using wifi on the lumia 1520. For sure there is something wrong with the wireless card or the drivers.
1. The internet speed while connected to wireless that i get on the 1520 is half or even more less than what i get on my desktop (connected wirelessly) or on my other phones (both being android). I get a 25Mbps download & upload both on the computer as well as on both the android phones. But on the Lumia it will hardly even cross 10Mbps for download and 16 Mbps for upload.
The issue with the speed is really strange because if i connect the phone to a 2.4 Ghz network i get upto 10 Mbps download and 16 Mbps upload speed.But if i connect the phone to a 5 Ghz N network then the download speed i get is 0.67 Mbps and upload 14 Mbps. Whereas both my androids have a download and upload speed of 25 Mbps no matter whether connected to a 2.4 Ghz or 5 Ghz network.
I have changed different channels on the router and have almost everything including resetting the router as well as resetting the phone but no luck. The phone is OOB lumia black OS.
Any ideas anyone.
What router do you have? My internet speed is 55mb down and 6mb up. I get 56 to 58 down and 6 to 7 up on my phone. I have an Asus AC1900 router. This phone has been one of the better phones I have owned when it comes to WiFi speed.

I have a netgear wndr 3700v2 router . I was able to resolve the 0.67 Mbps speed issue on the 5Ghz N channel by enabling WMM on the 5 GHZ channel however still the speeds are half of what is the internet connection speed.
The surprising part is that after enabling WMM the speeds on the note 2 when connected to the 5 Ghz N channel reach the proper internet speed as on a wired ie:- 39 Mbps but on 1520 they hardly cross 15 Mbps download .On the note 2 or my other android as well as my desktop the download and upload speed is proper on both the channels 2.4 as well as 5 Ghz. This indicates tht the router is fine.
I think i have to contact nokia support to have this checked. I am not sure as to what else to apart from this.
Same issue on a N97, wifi is muuuuuuuuuuuuch slower than 3G. Some messages I got about certificates let me suspect the preinstalled Boingo appli. All worked fine on my previous 5730.
After recently upgrading my family's phone's, we all now have 5 Ghz Wi-Fi capable devices, so I got a dual band AC 5 Ghz Asus router.
My broadband is rated at 20mbps down...ok, so testing with ookla speed test I'm getting the same transfer rates on either of the Wi-Fi bands (2.4 Ghz or 5Ghz)
I thought I read somewhere 5 Ghz is what you want, and should select that one....but now I'm understanding it has much less range but more bandwidth, but if I'm maxing out my 20m connection at 2.4 Ghz, what is the advantage of 5 Ghz?
(I hope this makes sense to someone who can reply)
5ghz is better if you are struggling with 2.4. Depends on how many mouths you are feeding. If you speed test near 20mb then don't worry about it cause ur not drawing a lot.
BAD ASS NOTE 4
2 things
1. Set them up as 2 separate networks with different names as passwords. Thus prevents devices from auto switching
2. As a general principal 5.0 ghz I'd better for streaming media and gaming, but does not go through walls well. 2.5 ghz is what gives your router is range. So anything that is streaming (eg. Xbox, chromecast, pc) you want on 5 ghz and close to your router, anything else you want on 2.5 ghz so it will work at longer range without losing signal.

802.11n on 2.4GHz can connect at a minimum of 72Mbps and a maximum of 600Mbps. Unless you spent a boatload on a router and live in the middle of nowhere and operate no bluetooth devices you're unlikely to get 600Mbps on 2.4GHz as it relies on having four antennae and a 40MHz block available. 5.0GHz is much less congested so you'll always get the full 40MHz channel and the speed is limited by the number of antennae on your router.
The Note 4 supports 802.11ac, which skews it more heavily in favor of the 5GHz band. 802.11ac can use up to 160MHz channels which can achieve a data rate of 1300Mbps on the 5GHz band.
Now, all of that is completely theoretical. I can tell you that my T-Mobile Cellspot allowed me to hit ~80Mbps on 2.4 and ~130Mbps on 5 when I had a 130Mbps connection. I switched to Verizon and took 50Mbps due to cost, and the router they provide will only hit 50Mbps on the 5GHz band. On 2.4GHz I see closer to 25Mbps unfortunately.
Basically, I would set it up at 5GHz and walk to the extreme end of your house. See if you can still speedtest at your full line speed. If you can, stick to 5GHz. If you lose signal, drop to 2.4GHz.
Thanks for the answers guys.
