[Q] Major WiFi Problems...

I just got my 64gb G6 Edge and am experiencing major WiFi issues with the device. My devices wireless will disconnect randomly from a strong signal and I have personally observed it disabling and re-enabling the wireless by itself.
Also once disconnected it no longer sees ANY wireless networks no matter where I go even though it shows the "scanning" circle spinning and I know that there are strong known wireless networks by me. If I manually toggle the WiFi off and then on again, all wireless networks around me are detected again and if any of my known networks are present it will automatically connect. However after a period of time this connection will disconnect and I have to do the process over again.
I have already made sure that 1.) Smart Switch is turned off. 2.) Keep Wi-Fi on during sleep is set to Always. 3.) Always allow scanning is enabled.
I have also tried disabling the WiFi Power Save mode [*#0011# and click on more>>WiFi>>"WIFI Power save mode"] this too resulted in the same behavior.
I've only had this phone for a day and a half, not rooted, already cleared cache partition from stock recovery etc. I haven't tried a factory reset yet (not sure how much good it would do), but at this point is there anything else I should try or is the consensus I need to get my phone swapped out?
**Update** So upon extensive further testing it seems that my wireless issues are caused by issues connecting to the 5GHz band on wireless access points that use bandsteering in that both 2.4GHz and 5GHz use the same SSIDs. This is a MAJOR problem for me as I encountered this at my place of work and rely on wireless heavily not to mention my phone heavily for wireless testing. There are no "Advanced" wireless settings for selecting which band to use either.
I really need some suggestions in order to try and get this problem solved or I may have to switch to a crappier phone just to have functional wireless.

I had something like that happen too, but I only noticed it at home. My home network has both 2.4 and 5GHz using same SSID. I set my phone to use 2.4GHz rather than the deault setting "AUTO", now it seems to work. Shouldn't have to do that though, but maybe my home network isn't setup correctly. This is not device specific though, it happened on my old M8 and now on s6 edge. So it must be on my end.

I have no settings for configuring WiFi bands, where did you find them?

Unfortunately I have already tried those options, what I am looking for now is the ability to manually select what wifi band 2.4 or 5GHz my phone uses automatically on the phone itself as Apollo stated he was able to do somehow.

I can only imagine he meant router settings because the S6 doesn't show that ability. Sounds like you have to get different SSIDs for your 2.4 and 5 bands.

Sorry guys, I was wrong. I upgraded from M8 to M9 last week. I had to change bands on M9, like on the M8. Didn't like the M9 so swapped out for s6 edge. I did not have to do this on s6 edge!
I had a brain fart..sorry for confusion, it was the M9.

This is what I have found out in my thorough testing on this. The S6 / S6 Edge have issues connecting to AC Wireless networks. Upon connecting the devices wireless connection to and AC Wireless access point or router it will become unstable and disconnect randomly and in my firsthand experience will not re-establish wireless connections at all until WiFi has been manually toggled off and then back on at which point the process I described above will begin again if connecting to any AC Wireless device.
A workaround for the moment for home personal routers is to separate the SSID's if they aren't already for both 2.4GHz and 5GHz and to use the 2.4GHz channel. This won't help however for all the places you cannot change that have AC wireless AP's installed etc. I am continuing to test this device for a while before I return it as I require functional wireless in my day to day job.
This is a huge issue, I contacted Samsung support yesterday about this (You should too) as I have confirmed that this is happening cross platform and carrier, S6 & S6 Edge, Verizon & Sprint that I am aware of so I'm guessing it all of them.

Gear S2 Wifi model: internet connectivity without smartphone?

Hi guys
I do not own the watch yet but have just been informed that apparently the WiFi model still relies on a smartphone to connect to the internet, is this true?
(I was told that the WiFi in the watch is simply a WiFi direct and that it will not work when the phone is off.)
My use case is the following: I wish to write my own applications for it that can connect to WiFi networks independently of the phone and can make API queries from Javascript
without using my phone's internet connection but instead directly connecting to,say, my company's wifi. Is this possible?
I know that without my smartphone active, the watch obviously won't have access to my smartphone notifications, but that is not what I am looking for in a watch anyway.
My ideas are going more in the direction of querying my own API for my server(via json) so I can keep an eye on its status. Does such a thing work with the smartphone being off, or is this something that works exclusively with the 3G version of the S2? I would love to get the 3G model, but it isn't being sold in my country.

Yes, it is possible. The watch connects to the WiFi by itself... You don't need the phone for that

Yes, using WIFI to connect other than the watch is doable, the problem that I had was the battery drain, it drained the battery in 3 hours when I have the WIFI set to on. so now I only use it Bluetooth to my phone, and with that, it lasts 2-3 days without a charge.

Portable hotspot issues with car wifi

Hi,
I've joined this forum to try and get some help with this along with any future issues as it looks like there's a smart bunch of people on here...
Please do move this to the appropriate area if I've put it in the wrong place.
I have a Samsung Galaxy S7 on a UK 'Three' contract.
However I recently bought a new car which has a WLAN feature - basically what it does is connects to your phone's portable hotspot, then broadcasts that internet connection on it's own in-car hotspot for passengers to connect to.
The benefit (because at first glance you think "why bother - why not just connect those devices straight to the phone's hotspot?") is that once the car connects to your phone's hotspot it uses the car's antenna to receive data etc which means you get a stronger and more consistent data connection.
So, the issue:
My portable hotspot works fine when connecting a device such as laptop/iPad etc directly to the phone.
However when I connect the car to my personal hotspot, and then a device to the car, it all connects up okay but I get errors on the end-user device saying that there's no internet connection.
I have done quite a lot of testing with this - for example in the following situations it works perfectly for the end-user devices - just never with my S7!!
- Connecting the car to my girlfriend's iPhone SE hotspot (on the same network)
- Connecting the car to my friend's S7 (on the same network?!!)**
- Connecting the car to my home WiFi whilst on the drive
**Interestingly, my friend's S7 was bought separately so had a pure Samsung build on it - mine came from Three so had a load of Three crap on it.
So, to tackle that, yesterday I did a cache wipe and factory data reset, then entered download mode and using Odin, loaded on the latest version of Nougat including all the new BL/AP/CP/CSC files.
Then me and my friend swapped SIM cards to see if that could be the issue, we tried using both phones. None of it worked, and now even his phone with his SIM card in it (which previously worked) no longer works with the car's WLAN.
It still doesn't work and it's driving me mad
Today I'm going to try messing with APN settings because I've read that changing the APN type to just "default" has solved some similar issues to this but without the 'middle-man' car in the middle.
I've also called Three and asked them to send me a replacement SIM card.
I'm sure it is NOT the car that's the issue, as it has worked fine on some devices.
I'm sure it is NOT the Three network that's the issue, as it has worked on 2 other devices on that network.
I suspect it's either some sort of config that needs changing, or the hardware of the phone is faulty.
I have a "remote management session" with Samsung support later today, but I don't expect them to be able to help with this remotely
Any thoughts or ideas here would be greatly appreciated, I'm sorry I've written so much but wanted to include all the info.
Thanks, Andrew

Question AutoWear for turning on LTE only when Galaxy Watch 4 is disconnected from Wifi/ Bluetooth

Hello everyone,
Is there a possibility to use AutoWear to turn on LTE only when the watch is no longer connected to the phone via bluetooth or wifi? I'm sure this will save battery life. One presumption is that calls over wifi to the watch would work. If they don't, not much point of turning off LTE.
I read a few posts stating that AutoWear for Wear OS 3 may not be properly optimized. Is this still the case?
I found a similar topic posted in r/AndroidWear 4 years ago and at that time, the developer had said that this isn't possible as they didn't have access to the LTE radio. Does anyone know if that's how things still are?
Thank you

No need for this. There is an "auto" option under mobile networks on the connection settings on the watch that does exactly what you say.

Oh that's brilliant!
Does it still stay connected to the network and turn off mobile data or does it pretty much go on airplane mode with only wifi and bluetooth being on?

It disables network connection shortly after you are connected to your phone via Bluetooth or Wifi.

Just to add that the same happens with Wifi. You can either fully deactivate it or have it on an auto setting where it turns on only if you are not connected to your phone via BT or for apps that required Wifi such as downloading songs on Spotify

That's exactly what I'm looking for! Thanks a lot for confirming this.
So essentially, if the watch is always connected to the phone, there shouldn't be much of a difference in the battery life between the LTE and non-LTE versions

There is only one problem - for me, setting LTE to car consumed 30% of the battery in 1 day, even though it did not lose the BT connection for a moment (maybe max 5 minutes).

Sorry, I didn't understand. Setting LTE to car? What does that mean?

I'm sure the author of the posts made the mistake. he wanted to say that the galaxy watch 4 has an error at the moment (01/21/2022)? at least for me, the bluetooth is connected, but the LTE connection stays connected as well, so the battery uses both BT and LTE, although my active2 when BT is connected, the LTE connection disconnects automatically ... although on the galaxy watch 4 the LTE connection is set to connect / disconnect automatically

Question Wi-Fi and Bluetooth issue on M12

Whenever I use bluetooth ear buds with my Samsung M12, while I am accessing internet through Wifi
(30mbps connection), my internet speed goes down drastically to a point, I cannot even watch YouTube video(360p) without buffering. (Update) Situation have become worse now, can't even open any web page, nothing works when I am using Internet through WiFi and connected to my buds via bluetooth (have tried different buds, headphones, neckband etc).
It happens only when I am connected to buds/headphones etc....otherwise there is no such issue while using bluetooth speakers, or transferring files through bluetooth or simply if bluetooth is turned on. DON'T HAVE ANY IDEA WHAT THE PROBLEM IS, HAVE TRIED RESETING MY PHONE,BLUETOOTH SETTINGS EVERYTHING.
(tried samsung service center also as phone is under warranty, they kept my phone for a week and did nothing)
Nothing works.
I am forced to use wired earphones and headphones while using WiFi.
(HAVE ATTACHED TWO VIDEOS EXPLAINING THE WHOLE SITUATION)
PLEASE CAN ANYBODY HELP ME.

It is because you are using another phone as a hotspot, this setup is slow. It requires more data when using hotspot. For each bit of data that the device you are viewing uses, the device providing the hotspot is consuming several more bits of data, a very inefficient setup. Using Bluetooth at the same time also slows things down because the radio is having to do extra work.

I understand that it is not very efficient setup, I did it in emergency situation. But the problem occurs on Samsung device specifically, i have F41 and oneplus 3T both works perfectly on this same setup while their individual Bluetooth is turned on, only M12 seems to not work

Does this persists on other devices too ?
And does it happen in chrome only or around the whole ui
Try system update

It happens because BT and WiFi shares the band the wireless connection. Either setup your wifi to use 5Ghz or change the channel of the router to something optimal, where other devices (microwave etc.) doesnt ruin your signal.
