Switching wifi to 5ghz only - Xiaomi Poco F1 Questions & Answers

Ok so i am stuck in a situation where my university has a wifi on 2.4 and 5ghz wifi with same ssid from a cusco mesh network. So what happens is my mobile always preffers 2.4 over 5ghz due to more strength but 2.4ghz band is over crowded. Found no option to only make it to conect to 5ghz band. Any sugesstion is welcomed or a way around or a temporary fix. Due to this my years old nexus 5 performs better in wifi performance than my poco f1. I have attached pictures with it so that you guys can understand what i am saying

[Q] Weak Wi-Fi?

Has anyone else had issues with the strength of the wi-fi signal on this phone? When I'm in certain areas of my house, I will have severe lag with browsing, with the People hub, etc. Music and video will stream poorly, with heavy buffering. Basically, I get all the signs of low signal. The problem is, I've never had a problem with other phones I've used, including an HD7, Dell Venue Pro, Nexus S, Nokia N8, etc.
I tested the WiFi signal in these areas, and I get back a consistent signal between 70dbm - 80dbm, so I have a moderate amount of signal to work with. Has anyone else noticed poor WiFi coverage with this phone? Should I get it exchanged?
Same. Something is definitely fishy with the wi-fi on this device. It seems to come and go, and manifests as poor or even no wi-fi capability even when the phone says it is connected to a strong wi-fi signal.
I frequently cannot get a solid Tango video call going between 2 Radars on my home wi-fi network. Pretty frustrating seeing "network problems" and getting a choppy experience when both phones are on wi-fi with full signal strength.
My WiFi is solid with my N router
Today is my first day with the radar and I'm noticing WiFi issues. I think though some of it is related to Zune WiFi sync connecting...

For the people connected to 802.11n routers, are your routers in pure N mode?
The Radar I have can connect to my 802.11g router no problem but can't even find my 802.11n. I'm thinking it doesn't have N connectivity...
Just asking.
Mine is BGN

I found out my particular problem is the Windows Phones only work on the 2.4ghz (currently used on my 802.11g router) band and not the 5ghz (my 802.11n router) band.
Now I know.
To the OP, this 2.4ghz band is usually crowded so maybe where you are going in your house, your phone is meeting with interference (land line wireless phone, neighbors wi-fi, etc...).

I don't think it's an interference issue, as every other device I own has no such issues, including 3 other Windows Phones (Dell Venue Pro, HD7 Omnia 7). And despite already using the channel with the least interference, I've tried switching that around as well. To me, there is clearly something not performing correctly in regards to the WiFi radio on this device.

Transformer Prime Wifi Question/Comment

Hi all Finally received my Transformer Prime yesterday and this device is truly amazing(coming over from the Transformer which i love as well). I was disappointed though when i connected to WIFI and experienced super low speeds.At Close range 4 down 3 up and medium 700 kbps down and 300kbps up(for the record i usually get 17 down and 5 up with my Galaxy Nexus and Transformer1 ). Although the speed is not great i figured a firmware updates would fix the issue. Fast forward to this morning at where I decided to try the Prime connected to my normally slower work network and I'm receiving a pimg of 5ms and 10 down and 27 up! This all leads me to the conclusion that there are setting on my router that need to be changed or a router model that is better than others for the Transformer Prime. I'm currently using the Trendnet Dual band 450Mbps Wireless N Gigabit Router( simultaneous 5ghz and 2.4ghz broadcast with wep security on the2.4 frequency) but i can test my oldish Dlink 655 N router tonight.
Anyone having luck or failure with their router configs or models let us know and maybe we can figure out what routers or settings work best of our new Prime.
I know the 5ghz on the prime is not enabled, so it can't see that frequency, that might be part of your problem at home. also use wifi analyzer to figure out which frequency has the least interference from other wifi signals nearby.

Its possible but the 5ghz is a separate frequency so it should not effect the 2.4ghz spectrum. As for WiFi analyzer thanks for the advice ill try that tonight as well.

[Q] 5GHZ Wifi

I was surprised to find that this phone supports bot 2.4GHz and 5GHz for wifi. However, I am having a problem getting it to connect to my 5GHz N radio. It will see it and says that the signal is excellent. I type in my WPA key and hit connect. It attempts to connect then goes back to disconnected. If I click on the name of it, it show signal as poor and link speed as -1Mbps. It connects fine to the 2.4GHz radio. The router is a Buffalo WZR-HP-AG300H running DD-WRT. Has anyone else had this issue?
i thought wifi was only 2.4ghz on this phone. my 5ghz network doesnt even show on my phone.
5ghz seems to be working fine for me
only certain 5ghz channels are supported. see if ur router is on channel 36 for 5ghz.

I have been able to use channels 140 and 149 as well as 36. What I did notice is that the first time I connect to (the very first time or if I make a change to the router) the wifi signal will drop and start several times.....I find if I just turn off wifi and turn it back on and reconnect it will hold.
Actually, I have it running on 144 and working now. I had to set the mode from N only to NA mixed.

I've got an apple airport extreme. my evo connects just fine on 5ghz
I have a Cisco ISR wireless router and I use strictly 5Ghz. It's wireless-A, not wireless-N, but it's strictly 5Ghz and it scan and uses whatever channel it wants. No issues so far.
I tried N network a while ago on my older phones (not 5Ghz N) and noticed more battery drain VS G. Since then I have switched my N to 5Ghz and just use my ipad3 for it. My phone I keep on G network. I don't see any real point to having it on a N network. G I still pull 10+ megabits down which is more than enough for pretty much anything the phone can do. Not really worth the extra battery drain in my opinion. My ipad I like on higher speed since I stream MKV files but the phone I think is pointless at least for me.

I actually had the exact same problem as you mentioned. The one thing I wanted to add to your excellent description of problem symptoms is that it says "Authenticating", and that is when it drops the signal to -1Mbps. Something during the authentication process seems to kill the radio connectivity. This has not happened on any of my other 802.11n devices. It connects fine on the same router's 802.11g. I had no issues with my previous phone (Samsung Epic Galaxy S).
Interestingly my router is a different brand but perhaps it shares some similar chipset. My equipment as follows:
Bone stock Sprint HTC Evo 4g LTE (on Ice Cream Sandwich, duhh)
Belkin Play N600 HD Wireless Dual-Band N+ Router (F7D8301 v1)
After reading the other posts here it inspired me to play with my Router configs for 802.11N. Turns out after making some adjustments I was able to get connected.
-I had the following selected:
Wireless Channel: Auto
Extension Channel: 40 (grayed out)
Wireless Mode: 802.11a&n -Worked after changed to 802.11n
Bandwidth: 20/40MHz
Protected Mode: OFF -Worked after changed to On
802.11e/WMM QoS: On
I honestly think it was the Protected Mode that made the difference. Here is what the router help page says about that feature: Protected Mode
NOTE: In most situations, best performance (throughput) is achieved with Protected Mode OFF. If you are operating in an environment with HEAVY 802.11b traffic or interference, best performance may be achieved with Protected Mode ON.
So long story short, try turning Protected Mode ON in your 802.11n configs first and see if that gets it going for you. Hope that helps!
P.S. After changes above I ran some Speedtest.net for Android tests (back to back) and got the following from the next room over (about 20 feet from router):
Test 1: On 802.11n: 17024kbps down, 5857kbps up, 27ms ping
Test 2: On 802.11n: 18134kbps down, 6266kbps up, 39ms ping
Test 3: On 802.11g: 15385kbps down, 6091kbps up, 25ms ping
Test 4: On 802.11g: 22212kbps down, 5785kbps up, 43ms ping

[Q] HTC One won't connect to internet using 5ghz wifi

Just got this phone today,
I have a Netgear R6300 capable of AC wifi but my phone wont connect to the internet when its on the 5ghz network. It works fine on the 2.5ghz but the other it connects but no internet.
I tried giving it a reserved ip and looking at the settings on my router but nothing is popping out at me?
Anyone have any ideas?

Check the Advanced Wi-Fi settings. Check Freq Band and make sure it is not set to 2.4 GHz only. Also try turning on "Best Wi-Fi Performance" and see if that helps.
Mine connects to my 5GHz network with no problems at all.
Hope that helps.

What router do you have? Also what kind of connection speed are you getting?
I checked freq and it was on auto, tried just 5ghz, also tried Best wifi but it still cant connect to the internet. I gets a connection with the router according to the phone but my 6300 doesnt show it as a connected device.
no problem here i can connect to my 5Ghz network with my a/n capable Time Capsule router. speeds are 55..27 Mbps download / 35.95 Mbps upload. my One wifi settings are set to Auto (vs. setting to 2.5 or 5 Ghz).
I have a Netgear WNDR4500. Speeds are 40 Mbps down and 28 Mbps up. That is with the router 2 floors above me in my house. My settings are also set to "Auto" as well. I connected immediately when I got home on Thursday after getting the device. I have had no problems at all with WiFi. Sorry I cannot be of more assistance.
I have no problem when connecting to my R6300 in AC mode ...
mine connects just fine
No connection at 5ghz, can only connect at 2ghz
I have d-link dr-825 rev B router with [DD-WRT v24-sp2 (04/01/13) std - build 21153] firmware. It has dual 2ghz and 5ghz radios.
I can only connect at 2ghz and unable to connect at 5ghz.
I have a dell latitude laptop and my old Galaxy SII has no problem connecting.
Howvever Htc-One lists the access point, correctly determines what kind of security is on (like wpa/wpa2 etc) but is unable to connect. I think once I saw a brief flash saying authentication failure on my phone when trying to connect to 5ghz. So I removed all security and made it completely open just to try. Again no connection without any error.
I am thinking of returning it if it is going to be a problem.
---------- Post added at 12:17 PM ---------- Previous post was at 11:40 AM ----------
Ok, I have solved the problem, now it is connecting. I made two changes in the wirless setup. Enable RTS/CTS protection and also enabled short preamble. After these two changes it is connecting as expected.

I'm having the same issue with mine and the same router, can not quiet figure out what is going on.
Just quick update i just did an update on my router and it seems to connect completely fine
For those who have router issues, check for a firmware update! Most routers have a few updates while sitting on the shelf. I used to always update and properly configure routers (with out the software disc) for customers at my old job and we rarely had problems of customers bribing it back. And throw out the disc that comes with the router. The software can cause headaches down the road. All security settings can be done inside the router through any web browser and router IP.
Just got a black ATT HTC ONE, everything is great, but no connection to 5ghz network here either.
I have a Netgear WNDR3700 and just updated to the DD-WRT build 21676, and still no go...

Prefers 2.4
I have a dual band N router, and my One seems to "prefer" connecting to the 2.4 GHz network over the 5 GHz.
It will work fine on the 5GHz, but I have to switch it manually when I walk in the house (so I usually don't).
I guess I could just tell my phone to "forget" the 2.4 network to fix this. On more thinking, maybe it's a coverage thing - it probably finds the 2.4 GHz network first. Lower frequencies penetrate walls better, right?

Correct. The 2.4 GHz network should travel further. Its all about that sweet sweet 5 GHz speed though! Mine connects to my Asus RT-AC66U router just fine.

You could always set it to 5ghz preferred. Mine connects to my netgear 5ghz ac router with no issues. Also if you have the same password for both frequencies it could just be connecting to that first.

I did check when sitting in my driveway - the 2.4 GHz network was still 2 "arcs" there & the 5 GHz was just a dot, so I think it is connecting to the first one it finds & sticking with it. In the Wi-Fi preferences, the "Wi-Fi frequency band" options are only Auto/5 GHz only/2.4 GHz only. No 'preferred' option - I'm running stock though - is there something different in the custom ROMs? I'm not afraid to root/ROM - I just haven't seen a good reason yet.

Use the only 5ghz only. There's a big difference with custom roms and stock att at the moment. There's new firmware etc. 2.4Ghz has more penetration through walls then 5Ghz. That's why you have more bars of one and not the other.

Well I want to be able to use the 2.4 GHz networks when available, so I'll leave it on auto. I guess the speed isn't a huge deal when the wireless connection is so much faster than my internet connection.
And yes, I know that there are lots of differences between stock & custom ROMs (my last phone was a Nexus S & I was always changing ROMs). What I meant to ask was if there was a difference with that specific option.
wifi 2.4GHz connection problems
Welcome
I have silver One for 3 weeks now, but it was 2 weeks in service - they reinstalled software and returned phone. No change.
I can't connect to any 2.4 Ghz network (G/N) ending Authentication Error. Only 5GHz works.
I tried it with Netgreat WNDR4700 (Gargoyle custom software), CISCO access point @ work, also random WiFi open networks in shops/malls, etc. Other devices i know and have at home ( Samsung Note II, htc Sensation, Acer Iconia tab, Dell Latitude laptop) works fine. Just the One cosing problems.
I run stock rom, how can I turn on more verbose logging or see what is happening in the Operation system while connecting? I must prove to Regenersis Poland service that my phone does not work. Otherwise they will say phone works within parameters.

Galaxy S21 Wifi switching issue between 2.4GHz & 5Ghz wifi channels

I have an issue with my galaxy S21 that is not automatically switching between my 5GHz & 2.4GHz wifi network when in close range to the router.
I have smart connect active on my router. When enabled, the 2.4GHz and 5GHz networks share the same network name and password(only one SSID will be displayed), and your wireless device will automatically switch connection to the Wi-Fi band that provides the fastest speed.
My device stays connected to the 2.4GHz network, I then have to turn my wifi off and back on again on my phone to connect to the faster 5GHz network when in range. My S21 is the only device on my network that does not do this automatically.
Anyome else experiencing the same or have a fix for this?

I've seen the same behavior. My configuration is the same as yours. I did a little experiment. I switched off the 5GHz range on the router. All clients switched to the 2.4 GHz range. Then I switched the 5GHz range on again. But even after 30 minutes, my 3 dual-channel android devices Galaxy S21, Galaxy Tab S4 and Galaxy S6 were still in the 2.4GHz range. Then I switched the S21 wlan off and on again. The s21 immediately connected to the 5GHz range and the other two devices followed immediately. Very strange. My WLAN router is a Fritz!Box 7590.
Otherwise, I know the behavior of the devices in that the devices only search for a new connection when the current connection is broken.
Sorry for my bad english, I am German.

Hi! These are router problems. Set maximum power for 5GHz and average or minimum for 2.4GHz. Prioritize connecting devices to 5 GHz.

I see that a stronger signal is important for communication than fastest band. Samsung has a weaker Wi-Fi transceiver compared to a laptop for example. In my dual-band router, I made settings as described above.
The Android device alone can select the WiFi frequency range. Try to make the 5 GHz band more "palatable" to the cell phone by temporarily blocking the 2.4 GHz band in the router. Then remove the login data from the mobile phone and from the router. Make a restart from Handy. Then register the device again and release the 2.4 GHz band. Then test the behavior.
Please let us know if it helped.
Edit: Make sure to use the original MAC address of the mobile phone when log in.
