WiFi is disconnected often - Redmi K20 / Xiaomi Mi 9T Questions & Answers

You will not have had the same problem but the wifi signal in my mi9 t is disconnected every so often. The further I am from the network the more it does but even when I am close, every 3 or 4 minutes it disconnects itself, when I am further away every 30 or 40 seconds. I also have a redmi note 4 and it does not have that problem and a mobile phone of another brand and does not disconnect from the wifi. However, with my mi9 t, you can have a decent connection that after 40 seconds loses the network signal and I have to press the wifi icon every so often and connect to the network again. Does anyone have a solution?

If you're on the stock ROM, you could try a factory reset.

Me with wifi disconnected problem , which is 2.4/5GHz hybrid access point. It seems to be the bug of my router, not the phone.
Connection to access point that has only 2.4GHz or 5GHz is no problem.

I have the problem with both access: Only 2,4 and 2,4/5 GHz. Other phones not have the same problem so, is my phone, not my router

[Q] WIFI problems

hello;
so i have a google N7 32Gb i updated it to 4.2.2 and suddenly it has hard times to connect to the internet.
on my laptop (also connected by wifi), i have no problem
on my desktop (connected with a lan cable) , i don't have any problems either
sometimes my N7 works like a charm but other times it doesnt.
I've mentiond when i turn wifi off and back on then i have like 10 seconds of browsing time.
Some have had success by forgetting the connection and rebooting the router, then setting it up again. Wpa-psk seems to be much more reliable than wep. Static ip in advanced settings has helped some. Mine is a dhcp enabled 802.11n with wpa/wpa2-psk encryption and has been flawless.
I use psk 2 but that isn't the problem since I get connection but the problem is my nexus only stays connected for like 5 or 10 seconds.
If I turn the WiFi off and back on on my nexus then I get connected again for like 5 or 10 seconds.
Weird enough I don't have this problem on any of my other devices ....
Yeah. I just started having this problem today on my Nexus 7 with Cellular. The HSPA+ connection doesn't have issues; I can surf normally but when I'm using Wi-Fi, it's problematic.
I didn't have this issue until recently. Very strange.

Wifi speed going down to 1mbps

Hi,
I have realized that my wifi connection drops down from more than 20 to only 1 Mbps with my lg g2. It happens with 2 routers and seems that if I reconnect the phone then I go back to more than 20 (and short later in goes down again). Any idea what can be?
No suggestions on this one? I tried the location services changes with no success. I would say it is some app causing issues, but no idea which one could be...

got exactly the same problem
switching wifi off an on solves the problem for 2 minutes or so. then it drops to 1mbps again. tried different routers.
I figured out that it only concerns internet traffic. LAN traffic remains at full speed.
WHO can help please? :cyclops:
hmmm. wonder if this is the same problem a lot nexus 5 owners have including me.. there's quite a big thread on it in n5 QA section
there's no fix but workaround solutions include running in 2g mode or turning off data when on WiFi and even making a script to do so automatically when entering WiFi areas.
http://forum.xda-developers.com/google-nexus-5/help/slow-wifi-n5-t2514501
thank you for that interesting link.
unfortunately the solution turning mobile data off didn't worked for me.
I also tried static IP instead of DHCP - no success.
one strange thing, as already mentioned: LAN traffic to my computer works perfectly with max speed. (copying files e.g.)
so, wifi works in principle. It's about internet traffic only.
but which kind of software/hardware is able to distinguish between internet- and local traffic?

[Q] Note 3 WiFi only slow on FiOS WiFi?

So this problem has been plaguing me since I got this phone. It seems this problem is only when I'm at home on my FiOS connection via WiFi through the supplied Actiontec 802.11n router.
If I am on any other WiFi network, my connection is snappy and instantaneous. But at home, there's always 5 or more seconds of latency before a web page will start to load, or before the network connection actually starts transmitting data. I don't understand it?? I factory reset both my phone and my router and the problem persists. Oddly enough, maybe 1 out of every 20 days, it will act normal and be as fast as it should be. It's totally random and not often.
Has anyone else had problems with their Note 3 through an Actiontec FiOS router??

Wi-Fi taking EXTREMELY long time to connect

It seems my note use quite long time (apparently 1 min) to connect to a Wi-Fi. I try several networks with the same result. My Z2 and s4 connects straight away. Anybody else have this problem?
Edit: After several tests I can say that the average connection time (from I turn wi-fi on and until connection is established) is 25 seconds!!!! My Z2 is 5 sec. and my Z2 tablet is 7 sec. What are your times?
Tested on 3 different wi-fi networks today and still all taking long time for connecting
Have not heard of this problem. Try resetting the phone and nothing is solved, then might be hardware defect. Use warranty or find a way to get a replacement would be my best guess.
I reset the phone - and I try to time how long time for connecting to the wi-fi (only have 3 wi-fi networks in range) It take 25-30 sek to connect - is this normal? Every time I turn on wi-fi the box with networks available come in.... Everybody get this?
This box I get everything I turn on wi-fi. Is this normal?

How long time does it take for your note to get connection?
It's almost instant at home, but takes a few seconds when I'm at uni (eduroam). My S4 used to be unable to connect to eduroam during the first few attempts, so the Note 4 is a definite improvement.

Is it really so hard to tell how long time your note 4 take to connect to a wi-fi........? ?

I think it depends on the hotspot you're connecting to. It's instant at home because it's a personal network, while in a university it's a more complicated structure with thousands of users connected at the same time. So I don't think there's anything wrong with your phone, it's more the networks you're connecting to. You other phones may connect quicker due to compatibility between modem and router.

It's probably a matter of compatibility between the Note 4 modem and your router. So long as it connects and the speeds are the expected, you have nothing to worry about.

Anybody else have long connection time???
I really would like some help here.... Could you please try to time the connection and post your result here.
I had something similar a few times, but a just turning off and on the router solved it.

Thanks - but I already tried to turn off and on the router.
After a bit more testing I found that it is actually the "start up" time for the wi-fi that's taking time - and not the connection time. If I change wi-fi network while the WiFi is on I nearly get instantly connection on all networks. So the question is if your start up time for WiFi also is 20 seconds???
I had this problem couple days ago. Restarted my phone and problem was gone.
Tried to change to a static IP Address - but nothing changes ?

Wifi disconnects and reconnects constantly

Hi,
just had the phone for an hour and almost right away after first setup the wifi radio disconnects/turns off and re-connects/turns on automatically every 20 seconds or so. No matter wich network I try.
Working fine with my S7 Edge laying here beside me, never had problems. I have three different networks around me I can try out.
Anyone had the same problem? I can find som info about this exact issue for the S7 Edge for some, but no solution from that works on the S8..
N
this is an old problem S7 had
you need to toogle in settings > connectivity > wifi > advance > smart network swithc OFF
i think this was - but dont remember well since it was a while ago - but basically you need to turn off the option of phone switching between phone and wifi data
Having the exact same problem with my Ubiquity wifi network (ie, not some janky cable company router) with my just-booted up S8. Smart switch was off by default, and after switching it 'on' and back 'off', no change.
This was the first thread I found on the topic, will update with any solutions.

Well I'm in Sweden and have no operator dependence. Neither for mobile or my home network (fiber connection owned by me).
This sucks though... I want this resolved

Try downloading wifi analysis app and see what it's picking up. Maybe you could try changing your wifi channel if it looks low?

No this has nothing to do with the routers or access points. I am 3 meters from the AP, its at 100% signal rate etcetera..
This has to do with Samsung and the software.

Download the wifi analysis app and see what the phone picks up.
Also in wifi settings on phone disable sleep mode and put to always on!

As I wrote I've tried all that I'm afraid. All the things that was recommended for the trouble on the s7.
have u tried going to a free wifi spot (starbucks, mcdonalds) see if the issue persists - maybe is your router refusing connection

As I wrote I have three different wifi to test with but yes makes no difference. This is a well known but not solved problem with Samsung phones.. three different makes of manufacturers, different settings with a/b/g/n and all show the same problems.
I also installed the small new update today for the firmware. Still same problem.
I'm guessing I'm about to get a replacement phone. I'll try that on Monday.
I'm not seeing the same problems with public wifi as I am with my Ubiquity Unify AC AP Pro access points at home - definitely weird.
When it is connected, I'm getting my usual 100mbps speeds, but it continues to drop regularly (not the every 10secs it did when I first powered it on, but every minute or so).
One thing that was mentioned was changing channel bandwidth from '40' to '20'... I don't see anywhere to do that on the S8?

Doesn't that mean on your router?
By changing the broadcast bandwidth from 40 to 20 you will increase the signal produced (same power is covering less channels)

I had this happen on a UniFi UAP-AC-Pro network with my S8 as well. I turned off Nearby Device Scanning on the S8 under Settings-> Connections -> More Connection Settings and that seemed to fix it. Strangely, I did not have the issue on my home network which has a single UAP-AC-LR access point with an otherwise similar configuration. Not sure if this setting change was really a fix, or if I just temporarily got lucky.
If turning off Nearby Device Scanning doesn't work for anyone, it might be worth playing with other settings within your network such as Band Steering. Some of these require turning on advanced features within the UniFi controller. Also I would be curious to hear whether those who have issues are on networks with a single access point, or larger installs with multiple access points.
Very recently got the Samsung S8 and I'm having some wierd WiFi issues. When connecting to the network everything is fine i get almost maximum download/upload speeds(500/500) from my UniFi AP-AC-PRO. But after being connected for awhile 30-60mins the speed drops to around 30mbit downstream and upload around 200mbit. If i disconnect from the Wi-Fi and instantly reconnect i get full speed again. I've tried switching settings in the ap, went from everything on auto settings to static channel/transmit power and been trying vht40/80 but makes no difference. If i have smart network switching on i get disconnected and put on LTE instead. All my other devices have blazing WiFi speeds as usual. I'm gonna try turning of nearby device scanning and see if that helps.
I started a thread in the ubiquiti UniFi forum as well but i cant link that here(not enough posts on this xda account)

I'm having the exact same problem as you. Wifi connects at full speed at first, then after a while speed drops. Has gone down to 1Mbps numerous times. Disconnecting then reconnecting fixes it for a while then it starts all over again. I'm connected to a TP-Link AC1900 running dd-wrt. May try going back to stock firmware on the router to see if that helps.
So has anyone come up with a permanent solution to this? I'm in the same boat with my ac-ap-pro and s8+. Disconnects every 20 seconds or so.
