Terrible wifi tethering (Global ROM) - Xiaomi Mi 8 Questions & Answers

I regularly share my internet over wifi on the Mi 8 and it's terrible, the connections keep dropping, and the speed is generally slow. I had a worse phone before that had a super fast stable connection with a custom rom. Do you have any experience with this? Any idea on how can I improve the stability and overall quality of the wifi? If I connect via USB and share the connection that way it's stable and fast enough, so it's not a network issue.

Weak wifi connection

Hello!
I am connecting to a wireless router with my Kaiser (it has WM 6.1),
and I noticed that in a not big distance the wifi just disconnects...
I changed the performance to be the best.
Is there any way to improve the wifi connection?
Maybe some 3rd party application?
Thanks!
Maybe anybody else has the same issue?
When I say weak connection, I mean that it connects in a distance of 3 meters,
but it disconnects in a distance of 7 meters, and a wall between the wireless
router and the Kaiser.
I use the official HTC ROM. Maybe there is a way to improve the wifi
connection?
Thanks in advance!
That's pretty extreme - sounds like a hardware problem. Are you absolutely sure it's not a problem with your router? Did you try experimenting with different radio ROMS? I've tried quite a few and I have found some that work better than others (WiFi, GSM, GPRS, battery life). It's worth a try, but research flashing ROMS first (on this forum).

slow tether

weather it be wifi or wired tether, it loads websites extremely slow, despite the fact of a good test speed on my phone, any idea of why this is happening?

Wifi thether or whichever cant procees your IC's full speed. The G1 is limited by the data chip inside, so internet speeds wil be slower then your desktop/laptop.
Same for me. I've done a lot of testing on this. Any sort of tethering, for me, will not yield xfer speeds in excess of about 700k. That's over USB or BT. My phone itself is capable of around 3000k on Wifi (using the Speedtest apk), but much slower through the browser. Max speed tethering over Wifi won't be known till T-Mo starts rolling out HSDPA. But based on the 3000k link over the phone's Wifi, I'm hopeful that a HSDPA-to-Wifi speeds could be in excess of 700k.

WiFi strength, range, and throughput

Rate this thread to express how you think the LG V20's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!
WIFI Multi Route Network Problem
I am having problems with wifi on my work network in the office. The explanation I got from our IT department is that the phone is having troubles with multi route setting on the network. Wifi home works without problems, but wifi at the office is not working at all. It is showing as connected but you cannot open any page nor get any internet access through any app. Anybody having this issue?
This is the first phone I've owned that has been able to fully utilize my home internet speeds. Every other phone has reduced the speeds by as much as half, and sometimes as little at 25%.
The auto switch between wifi and mobile data works great. There was nothing more frustrating than sitting in my car in front of my house, trying to pull up navigation and the phone running horrendously slow because it wanted to use my wifi that was 100 feet and 16 walls away, just because there was a signal.
I had the same issue with my wi-fi and internet signal for a time. Have you tried checking the phone lines in your area? Stactic noise in the lines may affect the stability of the signal. Have an IT expert check and replace the line if necessary to hopefully resolve the issue.
Signal strength is better than my note 7 before I sent not back I ran test checking data strength. I walked outside up the street connected to home wifi note lost connect 7 houses up the street v20 i was near 9th house
GPS accuracy, Lock speed, and reliability is poor for me. Can we vote on that?
My V20 is head and shoulders better than my Note 7 when it comes to networking performance. I had real, serious issues with throughput on the N7. My Note 3 would get ~5MB/sec transfers from my home Linux servers' SMB shares, the N7 would get 800-1000KB on a good day. The V20 is on par with the N3 on SMB, but where it REALLY shines is encrypted transfers via SCP. I can do SCP file copies at 80MB/sec reliably. It's amazing. I'm guessing we have some sort of encryption offload chip in the phone or something.
Does anyone else have this issue where the wifi cuts in and out every 30 minutes or so? I have a Netgear WNDR3400 router and I'm on Nougat 7.0
very lg-v20
lg v20 perfect phone-very speed.
my favorite phone
I agree man. Very speed. Much phone. Wow.

Auto Proxy
OK so I investigated the issue of not having internet through WIFI although connected to network, and the issue is that the phone cannot use auto proxy? My LG G4 did not have this issue. Setting up manual proxy through Drony app solves the issue. Any way to get this working straight out of android? Seems like 7.0 took a step back in usability.
I have a Asus AC68U router and the LG V20 reports the connection speed as 78Mbps, whereas my S7 Edge shows the speed as 173Mbps while connected to the same network.
Why is the V20 connecting at such a slow speed? Have reset the router, turned off Wifi optimisation on the phone, but speeds have not improved.
Is there anything else I can try out?

I have the same router. Mske sure you are connected to 5ghz and you will get adequate speed. I have no problems.
Wifi strength is good, a lot better than my G3. The download speeds are a little less than my laptop, like 35 vs 50 and 70 on 2 laptops, they may be connecting to different severs though, the speed seems to vary more on the phone. Sometimes it's slow to switch over to LTE when moving out of wifi range. Tells me no internet connection when wifi is too weak to get a good signal. Mainly an issue I think with a weak wifi signal that it's still trying to connect to.

What steps do you go through to make your v20 connect to work wifi? I have a new v20 from Tmobile and upon my 1st try to connect to work wifi, i can reach the splash login page, but after entering credentials, it bounces me back to the splash page instead of verifying that I have logged in. My older Nexus 6 has no issues connecting to wifi...

Solution to my issue: Not sure if it was a combination of things or just solely this tip from an LG rep:
Go to: Settings>Apps> (3 dots top left) > Show System> Wi-Fi > (storage>clear cache & clear data)
Tried connecting to Wifi after that and it worked on my v20. Also I entered in slightly different info in my work wifi splash page which may or may not have made a difference.
Hello, has anyone had a problem that they cannot connect to 5G on your router? My phone will not connect to 5G what ever I do, but will connect no problem to 2.4G. I've tested it with several different routers and all my other devices connect without any problems.
WiFi Issues
I was having issues with my WiFi at home only. Connected everywhere else. I found a post on this site that helped. The post was for a different issue. I just looked at all of the other settings that were available and did a little experimenting. My issue is fixed. WiFi is now good everywhere!!! I have T-Mobile so I am not sure if it will work with other carriers.
Dial-er code that got me to the right menu.
*#546368#*918#
I found that taking the metal back off my v20 improved download speed significantly!
I reported that in the discussion about people unable to get 5 GHz Wi-Fi.

WIFI slow / disconnecting

Hi
I received my 3T yesterday. I am having issues with WIFI
WiFi network drops frequently and the mobile data is used for some time and then WIFI is connected again. See attached .. This happens even when moving between rooms of my house
I think this happens when the mobile wifi changes from 5GHZ to 2.4GHZ when I move away from router
I have updated to OxygenOS 3.5.4 as soon as I received the mobile
The signal strength of the 3T is also very low
I have a 2 year old moto X 2014 and the moto beats the 3T at every place in my house
The signal strength and the wifi speed both are better in moto X
I have checked at various places
I have wiped the cache. Tried changing 2.5GHz to 5GHz
Changed Channels.. Tried all the things that I could find on the internet
But still problems
So is this a hardware problem and should I ask for a replacement? Or is this some Software bug which can be resolved
My router is ASUS RTN66U and a lot of other devices work seamlessly on that router and hence pls dont suggest to change the router
Awaiting replies
Regards
Ajjaykummar
I think this is a bug related to 3.5.4. On 3.5.3 my WiFi worked a lot better, but LTE Advanced is faster on 3.5.4. You can try a custom rom or downgrading, there's also a leaked OxygenOS 4 rom out.
Do you have wifi issues now when u have 3.5.4
I don't want to install new Roms. As I may have to return it in case this is a faulty piece
I'm having the exact same problem. I stream a lot. Very annoying when music video or gaming gets disconnect so often. My Galaxy Note 4, & s6 works fine.

yes, it started on 3.5.4.
here is a screencap of the issue
You can see in the screen cap that the mobile is connected to ASUS5 (5GHZ)
Then as I move away from the router the signal weakens and then the wifi disconnects .. and then it connects to ASUS (2.4GHZ)
Earlier it was connecting to ASUS but with a exclamation mark (without internet).. I waited for 15 minutes but it did not connect
Then I would connect if I switch off and on the wifi toggle
After that I did a factory reset and now you can see the screencap
It connects after a minor delay.. So is this alright
My other mobile - Moto X 2014 simply switches instantly from 5GHz to 2.4GHz and vice versa.. not even half of second is taken on moto x
Give the device a static IP use 2.4 network as it's more of a long range band. I tend to use the 5 band for stationary stuff. My WiFi works fine but all my home devices have a static IP.
This are the things that I did
1) Factory reset
2)Use Legacy DHCP client (under Developer options)
3)Disable Smart Wifi switcher (Advanced Wifi setting)
4)Static IP
This seems to solve the disconnection issue .. I still feel the wifi signal is weak compared to my other devices
Hope this helps someone facing the problem
regards
I had the same Problem on OOS 3.5.3/3.5.4/4.0 at the OnePlus 3T.
I tried every Solution on the internet and nothing worked for me.
But after i looked into my Router-Setup i saw the DHCP Section where i selected 'Renew DHCP every Day'
>>> Screenshot what i mean - imgur.com/KakQX3i.png <<<
After that it works perfect. No connection-issues anymore.
mine is already one day..
I thought it was resolved... but again I noticed slow wifi speeds
thinking of replacement
haven't had the phone long enough to experience disconnects but wifi is definitely slow...
I have a 200mbps connection, getting 160mbps on desktop with LAN cable, 110mbps on my OPO, only 50mbps on my OP3T....
all tested through speedtest with the same server location.
OP3T is chinese version flashed with oxygenos 4.0.1
edit: later tested again with OP3T getting up to 90mbps but still 20 less than the OPO
I have same issus like lajay. The Galaxy S7 from my wife works perfekt in the same Network!

Poor wifi connectivity and speed compared to other devices

My Nokia 7 Plus connects to my Netgear D7000 router on both 2.4Ghz and 5Ghz.
When the phone is near to the router it will max the connection speed out using speedtest at about 75mbps (max internet speed for me) however as the distance from the router increases the speeds drop off dramatically to either 1 or 2 mbps or they drop completely and it keeps trying to jump between networks presumably because the signal is low.
The drop in speeds seems to affect the download speed more than the upload speed.
I have an old Galaxy S5 and in the same positions it holds the connection easily and will still max the connection. I can go much, much further from the router before the connection drops.
If I use wifi analyser then I see that on the S5 the signal looks to be about 10db better, it simply looks like a case of the S5 having better reception.
How do others find the performance compared to other phones, is the wifi poor or do I have a duff one?
I'm currently using Oreo 8.1 with the July security update., has anyone noticed wifi being better using Android P?
Android p is far better

Thanks for the quick reply.
I'm just reading through the thread on Android P at the moment and will probably give it a try providing I can make sure I can roll back to Oreo easily so the device can be returned if it is actually faulty.
