Wifi Issue?

Hi all, happy Friday! I searched for my paticular issue but couldn't find anything. Just wondering if anyone else has experienced this issue or something similar. What happens is my revo isn't automatically reconnecting to wifi when i go out of range and then back in. I will notice it's using data (4G or 3G) and when i go to wifi settings the wifi network says disabled and i have to go to it and hit connect. What's more weird is it's doing this with the wifi at work but not at home. It's not an issue with the wifi at work though because other people here have androids, iphones and blackberrys and don't have the issue. The phone has done this since i got it. I've looked at the wifi sleep setting and made sure it is set to never to rule that out. I've done several powerdowns and battery pulls since i got it also. Anyhow just wondering if anyone has heard of this. Thank you and sorry for the length of my post.

That happens on my phone as well, but will reconnect to my home network after the screen is on for a few seconds

I don't have that issue but I always turn my wifi off when I'm not using it. Better battery life plus no issues

Yeeup, I've had that exact issue on this phone from day 1. Some may not consider it a big deal, but it's actually one of my biggest pet peeves about the phone. I was hoping the V6 software update back in August would contain a fix for it, but I didn't notice a change.

While that's a valid workaround, and i'd love to do that, it's not an option for me. I have the lowest data plan you can have on a smartphone (2gb), so i have to be on wifi whenever it's available so as not to go over usage. What's odd though is the phone only seems to do this with the wireless at work. I even went somewhere this past weekend that i haven't been in a while and the phone remembered and connected right up to the wifi there. Other smartphones at work don't behave this way with the wireless at work though. I'll just have to live with it, i'm used to it now anyway. Just have to remember everytime or i'll be using up my precious data. I'm wondering if the update to gingerbread (if our revo ever get it) will do anything with this issue.

What type of security is implemented at your work? I know there is a very common problem with PEAP and MSCHAPV2 authentication and FROYO. I can connect, but as soon as I change to another antenna, I get disconnected. It is the only reason I know I want Gingerbread. It was supposed to be fixed in Gingerbread.

Good question gig, work has 2 networks. One uses PEAP and the other is for guest internet access, i have it on the guest. I gather from what you've said it wouldn't help any to try this issue on the main PEAP network.

I have an update on my issue. I was at lunch yesterday and trying to connect to the free wifi there and noticed that the wifi network at work that's been giving me problems was on the list of remembered networks twice! I have no clue how this happened (in troubleshooting i always hit forget). I didn't even know it was possible for any device to have duplicate entries of wifi networks. I deleted one of them and it seems to have worked (so far). Some other people replied saying they were having my issue too, so i wanted to update this thread in case it would fix their issue too.

[Q] Anyone else having WiFi issues with their HTC One?

Hey guys,
So I just got my brand-spanking new HTC One today. I upgraded from the Evo LTE, and I already love it.
But there's one thing that has been really frustrating to me for the few hours I've owned this phone... It has major WiFi issues.
My One can see the WiFi network, can connect to it, but wont give an internet connection! It's so frustrating!
My Evo LTE, being connected to the same WiFi network, connects to the internet with no problem at all.
A temporary fix is to turn off the WiFi radio, then turn it back on. As a result, I would connect to the internet for a minute or so, then it would disconnect from the internet (it's still connected to my WiFi network, and it recognizes it, and it gives no messages about the connection suggesting that something is wrong with my router/connection).
I changed the frequency bands, but they all have the same issue. I have enabled "Best Wi-Fi performance" and "Keep Wi-Fi on during sleep."
I've also reseted my router numerous times... No luck.
Is anyone else having this issue, or did I just get a lemon? Can anyone think of a possible solution?
Thanks!

no issues here with my one and my netgear r6300 ac router.

Wi-Fi has been fantastic for me on my one. My evo LTE if you remember had the issue of wi-fi just shutting off after the phone was asleep. That was fixed in an update but even after that was fixed my evoLTE would show it's connected but data would not work. So I would have to toggle it on & off. I also had an issue with my sense widget not working and getting stuck. I was really starting to dislike the evoLTE because of it since your notifications quit working if your wi-fi was not connected correctly. I put up with crappy wi-fi for almost a year, mainly because I knew if I took it into Sprint they would say everything works perfect I just didn't wanna deal with. I know it's extremely frustrating to not have your wi-fi work correctly. My advice see if you can get a hold of another HTC one to test side by side. If it's a hardware issue you should get it swapped. You could also try hard resetting. I use a a WRT54GL with tomato at home and a Asus N66U at work, both have performed awesome with my one.

I have _exactly_ the same issue with my One. I have no idea if it's a software or a hardware problem. Tried a hard reset just yet, but it didn't seem to make a difference.
Really frustrating indeed, since the One is not very good available in the Netherlands yet, so if I return it, I might have to wait a few weeks to get a new one. I've tried it with at least 6 completely different WiFi networks, but the problem occurs with every one of them.

Only issue I have had with the WiFi thus far is it doesn't seem to have the pickup up range compared to my other phones and tablets.

WiFi on mine is insanely crazy! Picks up signal way better than any other device I've ever owned. Might be the kernel I'm running. Try it out! Look in the original dev thread.

I've noticed this as well. Areas in my office where I could get a decent wifi signal with my 3D I am dropping wifi completely with the One.

Router brand/model? Firmware version? WEP/WPA/Open? 2.4Ghz, 5Ghz or dual band? Channel (more relevant on 2.4 than 5)?
Does your phone get a valid IP? Check on the phone itself then the router under DHCP (assuming normal configuration, IP should begin 192.168.*.*)
Can you ping any internal node (ie your router) or external node (ie google.com or the IP to google)?
If your router has WEP/WPA enabled, switch it to Open solely for testing the connection.

Had the exact same problem. Only thing that fixed it was switching my router encryption from WPA to WEP. Works like a charm now. Best of luck.

Same problem and my solution
I had the same problem. Finally I tried to reset the phone without putting all my google-account info back. Then the wifi works fine. After that a Added my google-account and can enjoy my new HTC one. The phone is really good!
Note that in this way I didn't get all my setting back from my google account (like access points), but at it is working!

WiFi Issues

Not exactly certain where to post this (as I am not altogether certain the cause) so if mods have a suggestion to move it let me know.
I have a rooted Tmobile S6 (not rhe edge) running Sick as Hell custom Rom version X w/ Unikernel v9.
Periodically my WiFi signal will display the ER041 - DNS (or less frequently the ER081) error which I believe is related specifically to WiFi calling.
My GF has the exact same phone and the same setup (I think she has WiFi calling enabled as well).
I have run some tests previously where I turned WiFi calling off and still had hiccups with the WiFi (both home and at work).
It seems that when I clear the cache and reboot the issue resolves itself but only short term before I have to do it again.
No one else in the house is having WiFi issues such as me and I cannot seem to figure out if there is a setting that is throwing things off or what.
Any help is greatly appreciated.

Mine does this too but it usually clears itself up within a minute or two.

OP, check your IP address to see if your phone is getting an IPv4 address. I don't know why, but my phone was having major issues with this. I still haven't figured out exactly what the issue was; I was on Sow Nice, flashing back to stock solved the problem. The phone was getting an ipv6 lease, just not ipv4, for no apparent reason.
If that doesn't help, I would advise setting network configuration manually. However if ipv4 isn't working, this may not solve the issue.

WiFi Issues
Alright gang I need some brainstorming...and curious if any other T-mobile Galaxy S6 users are experiencing this issue. I don't believe it is ROM related but thought I'd post the inquiry in here anyhow.
Specs:
T-Mobile Galaxy S6 (SM-G920T) rooted with Sick as Hell X and Unikernel v9.1.
Baseband: G920TUVS3DOJC
Issue:
WiFi is intermittent (both work and at home). WiFi will be running fine on this device and also on my Kindle Fire and at some point WiFi on my S6 will stop working. The WiFi icon will still appear and the up/down arrows will flash but I can't pull up Google search results, YouTube videos, etc.
I get a ER041 - DNS error which is related to wifi calling but I think this issue is in fact DNS related (I've googled and googled and am just not entirely certain, if it is DNS related, exactly how to change settings to thwart this issue going forward).
If I run a speedtest I will get a "Network Communication Issues" message. If I turn off WiFi and then turn it back on the connection is still broken.
HOWEVER, if I clear the cache and reboot the phone, it will connect to WiFi for a period of time until the connection gets broken once again.
My phone seems to be the only device experiencing this issue. I have booted into Safe Mode and the issue still occurs so it doesn't appear to be app related. The Smart Network switch has always been off as well so I know that isn't the culprit.
At work I'm not going to be able to check the router settings but obviously I can at home (at home 4 other users connect to WiFi no problem).
There has got to be some sort of tweak/button/setting that I'm just not catching that is causing this. It is irksome.
I recently did a factory reset but the issue is still persistent. Scanning the interwebs this seems to be a pretty common issue with the S6 and Lollipop.
Any ideas??

Keep in mind, the other kernels are international
source.
EDIT.... also uni kernel adds a default.prop in system that has ro.securestorage=false when it needs to be set to true for USA devices

I'd say at this time I can rule out the kernel (it's a been a few days now running Twisted v7.1). I honestly think it is a Samsung bug. Not just S6 users but Galaxy S7 users are now reporting the issue as well (there is a thread over at AndroidCentral).
Just like myself, those users are reporting that Smart Network switch and Blutetooth and the like are turned off/disabled and yet the problem persists.

I've had WiFi issues on an s6 edge. But I figured it out that if I'm near my microwave and it's on WiFi dies on the phone. Soon as the microwave goes off it works fine ?

Dodgy wifi

Has anybody had any problems with their WiFi not connecting? My device seems to fail to connect to wifi after a couple of days and just sits trying to connect. Toggling WiFi doesn't seem to resolve it, and I have to reboot the entire phone to get it back online.

No problem here.
Connects very quickly, never seen it fail to connect, even on my works dodgy BT homehub 3, which used to tie my old Z3 compact up in knots..

Yep.I thought that Snapdragon 835 cause this problem. Xi oami 6., ZTE z17 and Op5 had the same question with WI-FI connection.

I have a sd835 s8 and I haven't had any wifi issues whatsoever since launch. It's a sample size of 1, but I don't know if it's truly due to the sd835

I haven't had any WiFi issues. In fact my WiFi connections have improved using the XZ1 compact over the X performance (the X performance dropped its WiFi connections 3 times during my data transfer to the new phone)

I've had my XZ1c for about a week now (European model) and it connects to my home network (5G) normally. Signal strength is fine, although the galaxyS6 it replaced definitely had superior reception. I do have wifi issues, but only when already connected to the network. When the phone is asleep (screenlocked) it seems to lose an active connection. The wifi connection should be on at all times, even asleep. It will show the wifi symbol, but data apps don't load, and it will have lost the connection as remote for spotify connect (playing on my reciever). It will also switch to mobile data at random times with normal wifi signal strength (even though I toggled this function off in the developper settings).
I'm not sure if this is something that can be fixed through system updates. I haven't seen any forum posts with similar problems though, so I'll try to document what is actually happening before I contact Sony support.

I bought the US version and flashed the UK firmware to get the fingerprint reader to work. No issues whatsoever with this phone. No Wi-Fi issues, overheating, signal strength, battery, nothing. Everything works just perfectly.

Same issue here. Mine is Europe (NL) version. The upload and download speed can be very unstable. And especially when I take it a bit far way, even you see that it's connect to the wifi with full signal strength, it said internet is unavailable.
I'm not sure if this related to the system update of last weekend or not.

Further to my issue. My phone will drop wifi connection and repeatedly try and connect - it usually cannot see any other networks at the time. Restarting the wifi on the phone, or rebooting the access point do not help. Running a packet sniffer on the LAN shows no activity, which indicates the issue is to do with wireless handshaking.
The problem occurs every few days and the only way to resolve it is to reboot the phone, which fixes it instantly.
I contacted Sony and they told me to do a complete reset on the phone, this didn't work. I updated my findings and pointed out that it's seems to be a firmware compatibility issue. Of course, you only get to talk to first line, and as a reset didn't work, they want me to send it off for a warranty repair (which of course will be returned with "no fault found" as no doubt their wifi will be different enough for it not to have been picked up on day 1 testing).
I'm currently trying to gather a bit more information on the fault, e.g. does it only happen on my home wifi etc. I've disabled channel bonding but that didn't help, and I've not jiggled my DHCP settings after seeing plenty of posts describing wifi problems on Oreo for other phones.
It doesn't happen frequently enough and I don't have the time to delve deeply into the network to identify the cause.
One interesting thing was that it went funny at home, but it was working when I got to work. When I got home it still couldn't connect. So I suspect it's to do with a particular compatibility issue somewhere.

no problem here conecting to 5 and 2.4 wifis...

I haven't gotten around to this yet. Do you still have wifi calling and volte available?

So far my wifi has been fine...

Mine is worst, i couldnt get it to connect at all but all my other device including xperia xa, xzp, laptop, Ps4 PS3, everything connect without any issue whatsoever, already excahnged once and still the same.

Think mine is struggling with either a single access point or VLANs. I need to dig further, but that requires buying a new AP - this phone is getting more and more expensive!

exactly same issue as Dashers describes with my XZ1c. I am not watching it closely, but it seems that it is hapenning after around 2 days online. Never happened before on same network with my previous Z3c, which had run months without restart and any problems whatsoever (till its display died

I have more or less the same issues, and a reboot always solves it. It happens with both routers form ASUS and Draytek.
Additionally I see issues with Spotify connect dropping or not being found on my Sonos (hardwired to LAN), but not so much to Chrome Cast Audio on the same network.

I don't have a problem connecting to wifi, but I seem to have a different issue. Even though wifi scanning is toggled off in settings, my phone still seems to be scanning according to Battery Historian. I think this is one of several things contributing to my high idle drain. Does anyone else have this problem?

Yes, wifi and BT scanning are both turned off in settings and have been since the beginning, but both seem to be happening anyway according to Google's Battery Historian tool. When I go back in to see if they've been toggled on by an app or something, they still appear to be off.

I have this exact problem. One second its 100% signal and is workin as expected. The other second it just drops and tries to reconnect like crazy. I have even had moments when i am unable to find my wifi after said disconnect. All my other devices is working like normal on my wifi. Using Asus n66u 5ghz.

I have been having the same issues as mentioned above with my XZ1 compact(european). My issues with dropping wifi signal seems to be happening when there are two different wifi signals to choose from. They are both on my local network. One is an extender due to the size of my house. When it can detect both signals, it can't make a decision on which one to choose. Once I remove a device(forget wifi device), it stays connected to the other with no problem. Since it isn't trying to compete with the other.
Has there been any improvement on this issue?

Wifi problem on s10/+ !!!

My wifi keeps dropping as well, it's getting to the point where I might return to Samsung unless it's fixed in a firmware update!

Same problem started to happen recently with my phone but only with 5GHz WiFi.

Getting the same problem with 5ghz as well, have to shut it off and then reconnect to the router. Their networking coding is a disgrace, tons of complaints about it all over the place and Samsung does nothing.... I can't return my device but if you're still within the period of being able to, I would if I were you. I absolutely hate this device and all its problems.

I"m having a similar issue. First I noticed that LTE would stop working until I rebooted. Then the wifi would glitch up the same way. I'm not sure if it's the switch from one to the other, or what the deal is. The worst part is it's not repeatable. It just seems to do it randomly.

I have encountered the same problem with wifi dropping. I went to wifi setting and forget network and reboot. Punch the password back. Its working fine now. By the way im using the latest s10+ firmware rooted

Hi guys,
I was faced to the same issue since I bought my S10e. DO not mind the solutions proposed on generic sites (thecellguide.com, thedroidguy.com), they're garbage, totally irrelevant (reboot your phone, erase your cache blabla).
I've tried several hypothesis to troubleshoot this issue (very inconsistent wifi connection with my TPLink 4G routeur MR600, disconnecting every minute or so). In fact, tens...
And the final word seems to be, as observed by other users: 5GHz. After disabeling the option on my routeur (switching all traffic to 2,4GHz) everything is fine. For now.
Good luck
Chris (Fr)

I've also had this issue on the S10E where the wifi would be connected but no internet. After a few minutes it would no longer see the wifi. 5ghz of course. 2.4 no problem. I noticed this happened right after login to Samsung account. Now that I'm logged out Samsung account wifi is all good. I'm on the oneui 2 Jan sec update.

I have the same problem with my girlfriend's Samsung S10, it keeps disconnecting from 5GHz. Just now I switched her to 2.4GHz to see if it solves the problem. All our other devices (HTC One M9, 2x laptops, raspbbery pi 3, chromecast, google home) have no problem with the WiFi on either band.
Samsung really has a problem with it's network code, I also had a problem at work with Cisco APs when an Apple device and the Samsung S10 where on the same network it would bring the whole network down. It was some multicast bug where the Apple would announce itself as the gateway only when an S10 was present.

It's happened to me but never until after the last update. I noticed yesterday I was connected with no internet.
