[Q] Is there an app or method to tell if you are connected N or G wifi?

I am trying to troubleshoot my router, it does b/g/n
I have it set to g/n
I want to know if there is a way to tell whether the cappy is using the G or the N radio
I cant disable G, I need both on but I would like to see that the phone is using N if it can

quite simply, if the router you have isn't dual-band and is just using the 2.4GHz range and NOT the 5GHz range, then yes, your phone is connected at wireless n. but just because you have a theoretical max of 133 Mbps (or 300 Mbps if you bought the router within the past 6 months) doesn't mean that's the thoroughput you're going to get.
likely, depending on where you live, your internet connection tops at about 10 Mbps (that's megabits, not megabytes)... some places (especially if you have fiber) around 50 Mbps...
so realistically your phone is likely maxing out any downloads at about 2 megabytes a second... 10 if you have a really fast connection.

I am not asking due to speed
I am asking
Is there a way to tell what type of network your wifi is connected to, b/g/or n?
not just to my router, but anytime I am on wifi
on the phone?
on a XP?
on Mac?
PS
DD-WRT shows channels higher than 11 so those must be the 5Ghz channels
it is a WRT300N btw

the cappy doesnt have a 'n radio' and a 'g radio'
the cappy has an 'n radio' and 'n radios' are backwards-compatible to pickup older signals
you set your router to output g/n signals, your recieving device will pick up on the fastest signal
to test it, look at your data speed,
in windows click your wifi in the corner > status > SPEED
on your phone... Menu > Settings > Wifi > click your network > Link Speed
mac... i dont care.

Think that router didn't allow for auto switching between 2.4 and 5Ghz channels. You have to select it, so the one you select is the one you are using.I font think Lynksys starts auto switching until the 400N. On other networks,.use speedtest. Anything over 5.6mb (i think) is n speed.

[Q] Can a Nook do better than 54 mbps Connection

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 bet that's the case with mine too, but I haven't checked. It does pick up signals like its running n though.

802.11n operates on both 2.4GHz (20MHz bandwidth) and 5GHz (40MHz bandwidth).
Anyway, how do you guys check out the rate on the NC?

I know, but I've heard of routers that do compatibility mode by segregating g and n between the 2.4 and 5 GHz antennas

Didnt realize all n routers did this. Checked mine and it shows my computer on 40 mhz and Nook on 20.
To check Nook connection link speed just click on the connected network and it lists all info for it.

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.

Does the HD7 really do 802.11n?

Until recently I was using Connectify to set up a home wifi hotspot for my phone (TMOUS HD7, running 7720 with the latest T-Mobile/HTC firmware) to use. Yesterday I installed a router instead, which has allowed me to play with more network settings.
If I set the router to 802.11n-only, my HD7 can see it but can't connect. If I set it to 802.11g-only, everything works fine. Has anyone actually confirmed that the HD7 can do "n"?

my home wifi network is "n" and both my hd7's connect to it fine.

I have forced the n-mode, no problems connecting

Yep, Wireless N works perfectly fine here

Which 802.11n are you talking about? 2.4Ghz works but 5Ghz won't. so it only does draft n not full 300mbps 5ghz 802.11n

You are comparing two different things, WLAN standard has nothing to do with frequency, HD7 follows IEEE802.11b/g/n standard operating on 2.4 GHz with 20/40MHz bandwidth, allowing maximum throughput of 150Mbps. It is capable of DSSS and OFDM modulation, and is also capable of operating in dualband mode, which allows it to connect to 2.4 GHz and 5GHz IEEE802.11a/b/g/n networks, this is however up to the OEM to enable this feature, this is not the case for HD7, or any WP7 device out there.

Draft-n was 2.4ghz 150mbps was it not? where as full rate 802.11n is 300mbps and operates at 5ghz?!

Well, yes and no, 802.11n is capable of data rates up to 600 Mbit/s, those are achieved only with the maximum of four spatial streams using a 40 MHz-wide channel. However, when in 2.4 GHz enabling this option takes up to 82% of the unlicensed band, which in many areas may prove to be unfeasible. I don´t have device which is able to be set to achieve this limit (2.4GHz / 40MHz with 400ns Guard Interval), so I can´t test it. Do you have internet connection that requires such a high value?

lol personally now i don't my links is 17mbit but i like the 300mbps for video streaming and file transfers, if only i had an access point with a gigabit lan interface haha

WiFi bandwidth? 5Ghz vs 2.4Ghz - how to test which is better?

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.

Low wifi speed

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?
