I was having issues with my WIFI also. It wouldn't connect on 2.4 GHz but would on 5 GHz. The performance wasn't great and I would get the connection isn't stable message a lot. I tried a bunch of things on my router and finally just did a factory reset on the router. I can now connect of both 2.4 GHz and 5 GHz. My connection speed has also improved dramatically. I didn't think it was a router issue since the Note 3 WIFI issues are pretty well known to be a problem. In my case, doing a factory reset on the router helped my problem a lot. For reference it is an ASUS RT-AC66R
I used the app WIFI Analyzer from the play store to monitor the signal strengths. Since doing the factory reset on the router, I only see the connection is unstable message very rarely.

I had same issues I thought phone was junk but it was my router. So I upgraded and set my Wi-Fi channel manually and not I am without Wi-Fi issues

You can turn off the option in the wifi settings that lets the phone auto disconnect from wifi if it thinks the wifi signal is weak or unstable. I sit 10 feet from my wifi router and it used to go back to the cell signal randomly. I disabled the auto switch option and no issue since. My wifi at home is very strong so I think its a bugged setting or something.

"Your network connection is unstable, so we in our smart thoughts have decided to disable it. Kiss my Gritts ". Ho Hummmmm

click dont show this option again

Wifi
If you are sure your WiFi is good, then go to WiFi settings,
1) Switch OFF Auto network switch
2) Keep Wi-Fi on during sleep: Always

This is a known bug that tmobile had ignored from the beginning. ... all note 3 phones had it. ..tmobile is the only one left with it. ..

Man, wish I had known about this... My Nexus 5 and 7 (and office iPhone 5S) all have excellent Wifi connection at my home.
I bought Note 3 to use the Wi-Fi calling feature and this caused me to missed multiple phone calls. Apparently, when the Note 3 is on Wi-Fi calling, it sorts of "disable" or reduce the cellular radio signal - zero bar shown on my Note 3 - all calls and SMS go through Wi-Fi. When the Wi-fi drop, it takes sometimes for the Note to establish cellular connection and that's when I missed the call.
Not to mention I am browsing happily or streaming Netflix and BAM.. wi-fi dropped and everything stopped.
If the Kit Kat upgrade fixes this issue AND not bring anymore problem (as evident from numerous threads), I would have upgraded to Kit Kat already.

Dammit, over the course of browsing for an hour, the wi-fi disconnect over 5 times.
What the hell!?

WiFi slow after Marshmallow update

Is anyone else having slow WiFi after the update? I did a speed test with my wife's S4 and had over 20 Mbits. But when I do the speed test on my S6 with M I barely get 1 Mbits. Is there a quick fix or is this an issue that we have to wait for an update.

WiFi still works perfectly fine for me. Have you tried resetting your connection to the WiFi?

Yes. Reset the settings on the phone and rebooted the router. Still acting slower than the phone running lollipop.

My wifi became very slow after MM - no resolution yet

I'm also having this issue. My router also has a 5g band however that works fine. But the normal wifi is very slow.

Well I removed my network from my phone and reset the router. Set back up my WiFi and now it seems to be better now. Will keep checking.

I had a network extender (slower than my wifi connection point), after MM installation, MM always connected to the slower extender. I deleted the extender definition, reset my connection point setting. Wifi performance improved close to what it was before MM.

This happened when I updated my wife's phone, I did a factory reset and started like new and fixed the issue... I didn't have this issue when I updated mine tho.

I still having issues with slow WiFi. Almost as slow as dial up sometimes.

Trying turning on bluetooth, it improves wifi speeds for some reason.

I finally gave in to doing a factory reset, that appears to have solved the slow wifi problem.

After performing I found out that the Retailmenot app was having an adverse on my wifi performance. I turned of the notifications for it and the problem went away. My son received the Marshmellow update and had bad wifi performance. Also his mobile hotspot wouldn't work. He uninstalled Retailmenot, wifi problem went away and hotspot began working.

Today I found out that if I have the Bluetooth on my WiFi crawls very slowly. If I turn off my Bluetooth my WiFi is full speed. So now I know it is the Bluetooth affecting WiFi. Any suggestion on how to fix this. I have a GearS watch and need to keep my Bluetooth on all the time.

Wifi speed problem

After the last pie update, wifi speed is not good enough.
When i test speed with oakla, its almost 5mbits. If i turn off location, everything is normal. If i turn on location wifi speed is getting worse. There was no problem at oreo. Is there any solution about that problem?

Do you have bluetooth on? I found out that when m bluetooth is on, WiFi conwction ia really bad. This os only on pie.

I've the same problem here...
WiFi + localization on = slow wifi performance 5/7 mbits
WiFi + localization off = normal wifi performance 50/55 mbits
The problem is after pie update.

there is no difference after February 19 update. that is terrible. shame on Xiaomi

For me, it seems as the problem is not localization but Bluetooth. When I turn off bluetooth, it's normal speed and when Bluetooth is on, it drops to incredibly slow speed. Altough localization might interfere with it, because it uses Bluetooth, I don't think it's the root cause.
Also, it is not only the speed between a router and the Mi A2 Lite that is slow, but also the connection from Mi A2 Lite as hotspot to any other connected device.

For me this issue all resolved when I installed a new router at home. I know this isn't a proper solution but if you have a backup router, give it a try.

After bluetooth is off,i have fast wifi,when bluetooth is on wifi is slow speed.

Some news about a soluzion? I have same problem.

For me the only solution is to use 5GHZ wifi.

For me, it appears to happen when I use both. I used to have always localization on and bt off but recently I bought a mi band I that forced me to enable bt aswell. Wifi speeds decreased a lot since that. Now I tested and with only one of them off it works great but with both, it doesn't.

You on stock ROM, and what version?
On Android Pie (stock, at least), it is a known problem that turning on Bluetooth or GPS will decrease WiFi connectivity and also some users reported that it will decrease Internet speed too. Hopefully Android 10 and / or incoming updates will fix it but this is Xiaomeme were talikng about, and Xiaomeme + AndroidOne = bugs and Xiaomeme's 'don't care' attitude.

But Bluetooth increases the Ping.

A50 WiFi problem

Hi,
My Samsung A50 is a great phone but has a annoying WiFi problem I'd like to solve.
Whenever I connect a WiFi capable of 5Ghz, at some point it starts to switch to 2.4 GHz constantly and back to 5Ghz, making the WiFi unusable.
This happens even if I am close to the router.
I have already reseted the phone and cleared cache.
How may I solve this (besides router solutions like creating two seperate SSIDs as I use this smartphone at an enterprise level)?

can you change de band manually??

Very low internet speed over WiFi

Hello.
What could be the reason for the low speed of WiFi internet on the SPH-L710?
The maximum speed through WiFi is from 1 megabits to 8 megabits. The speed is very unstable.
Re-flashing the phone did not solve the problem.
Another phone of the same type (SPH-L710) downloads files at the same time at a speed of 40 megabits.
Both of the same phones have the same firmware.
We don't have CDMA operators, so the phone is used in tablet mode, and the Internet is only via WiFi.
Please help me to solve the problem.
Could there be a problem with the changed parameters of the radio module? Is it possible to reset the parameters of the radio module to factory settings?

You might want to look at the Advanced WiFi settings in the Settings app. There might be something in there not giving full priority to wifi radio. On your Samsung, go to Settings>WiFi>click three dots>Advanced.

There are no such settings there that could affect the speed of WiFi in such a way.
Two identical devices with the same firmware. All WiFi settings are the same in both devices, but one has no speed issues and the other has. Two devices were in use by other people.
Are there any engineering settings that could affect WiFi speed and which won't reset after a Hard Reset?
Or is it a defective device?

Does anyone have the L710VPUCND8 or L710SPRDNJ2 4-file firmware?
