WIFI Problems

My wifi if being finicky, like not wanting to connect, or even see my home router, is anyone else having any trouble with wifi?

it must be your router.

no problems here...

I was running it with the following:
SSID broadcast off
WPA2 Personal
Mac filtering
I turned SSID broadcast back on and it works fine now, someone else want to replicate those settings and see if they have problems?

I am having problems connecting to my wireless router, my Evo is saying I have a "poor signal" at my computer desk but my computer is showing me at 100% signal. I think its a Evo software thing but thats my 2 cents. I don't use my wifi often with my phone any way so no biggie for now.

I also have ssid broadcast off and I cant get it working.

Hi everybody, So far I love the EVO even without 4g. Anyway after I turned on my ssid I connected okay. I can see the market and find what I want to download. It says downloading but never does. I have downloaded apps with the 3g but I don't have a signal at my home. I always used winmo before and had no problems downloading on my home network. I wondered if anyone had any suggestions as to what I might be missing. I got root okay and have been having a blast but I sure would like to download some more apps while I am at home. Thanks, Rick

SSID broadcast off and no issues for me thus far.

Yes, me too. Sort of.
My Evo shows 1 bar of wifi signal strength at a distance of 8 feet from the router where my iphone shows full bars. I do get decent download speeds using xspeedlabs free but the upload speed seems to cap at 750kbs where the iphone goes over 1mbs with the same test. There is definitely something weird going on.

I am having similar results as far as signal strength. Sitting 2 feet away from my router I am only showing one bar of signal strength and getting very slow speeds. All of my other wifi devices (including those that are on the opposite side of the house and downstairs) are getting signals ranging from "good" to "excellent". Something definitely seems to be up with the wifi.....

I was having wifi issues too. I'm running dd-wrt on my router. Turns out just power cycling the router fixed it. I think I'm going to setup my router to reset weekly.

I get the same issue of having 1 bar of signal strength, regardless of how close I am... even tried on 2 different wireless routers, Linksys-dual band N, and Net gear A/B/G.
I get strong signal from both routers on all other devices, iPhone, iTouch, Touch Pro, Laptops, etc...
I've played with all the settings on the EVO, turning off the mobile data and only having wifi on, changing the encryption settings on the routers... nothing seems to work.
I love the phone, but kinda bummed about this issue.

I have ssid broadcasting turned off and I'm using WPA 2 with no problems.

There is a long, angry thread about this over at HTC's own EVO forum: http://community.htc.com/na/htc-forums/android/f/94/t/2929.aspx
I'm also getting less Wi-Fi performance on the EVO than on other devices in the house.

Using Fresh 1.0.1 rom and also the new Cyanogen rom, with the SSID off, I cannot connect with WiFi, with SSID on, it works fine. Using Cisco/Linksys e2000 router.
Tested with my iPhone with SSID off, it connects no problem. So the problem is not my router.
Is this limitation of EVO?

Radios Dropping

Anyone have an issue with their phone randomly dropping Wifi/Cell connections? Sometimes it doesn't happen for a day or two sometimes it happens 3 times in 5 minutes.
Starting to think my phone is defective...

If you are on a custom rom try going back to stock and see if it's the same. If stock try to update profile

I've tried that and it's still dropping... Would PRL/Profile also effect my Wifi connection? All data connections drop.

I'm having the same issue with Wifi. It'll still show as being "connected", but there won't be any data coming through. I'll have to toggle Wifi on/off to get it back. Sometimes it'll work for a couple of hours before having the data issue again, sometimes less than a minute.
I'm on stock, rooted.

Connections optimizer is off for me too - My phone shows a clear signal disconnect and reconnect (The wifi bars/3g symbol disappears completely) during this time all data connections fails - including texts. This is happening when I'm staying in one area so it couldn't be a tower reconnection issue.
I'm going to try taking my phone into a sprint store today to see what they say.

Ah, it sounds like our issues may be different then. My issue is solely with Wi-Fi (haven't noticed issues with 3G). When it happens for me the Wi-Fi icon in the status bar doesn't change, I just can't connect to anything.

Yup, same here. Seems like the 3G radio does the same thing, but not necessarily at the same time as the WIFI. At first I thought is was only the WIFI too, but 3G is affected, though not to as severe a degree. My WIFI was actually disconnecting and failing to reconnect. Turning off connection manager made no difference. I did however notice that the WIFI at my work (WEP encryption) never seemed to do this (at least I didn't notice), so I changed my home network WPA to WEP and sure enough, it stays connected. Was still failing to load occasionally, so I went even further and changed the router to a single channel rather than "Auto" and set it to "N Only" (due to having a similar problem with a laptop I used to have, with a similar solution). Problem fixed. I'm using an Amped R10000 just FYI, not sure if it matters. Very annoying, and given the number of occurances being sufficient to start a thread, I'm assuming this is a common issue and will hopefully be fixed by a firmware update. In the meantime, we should probably all start calling Sprint daily and complaining. Maybe they're not even aware of it. Probably not enough of these phones in circulation yet for them to worry about it.

Mine will do this from time to time. Stock not rooted. I will have full 3g bars and full wifi bars and my data will just hang. If I turn off wifi everything works again. Some times when I load a game that has to connect to Facebook to play against friends I have to close the app/game, remove it from memory and reload it to get the data to work. Same thing for Pandora. It will load a song to 2% and hang until I stop wifi or reboot the phone. It's not an everyday thing but some days are worse then others.

"Good to see" from the perspective I thought it was just me. Things described by others happening to me as well. Personally, I find I like the wifi/3g auto connectivity feature - when it works. Got my SGNII on Thurs last week, and connected to wifi at work on Friday no issues. This morning, the Note picked up my work wifi without a hitch.
At home, over the weekend, I was getting spotty connection, sometimes no connection to my wifi. (Disclaimer - I have my main wifi @ N/5ghz. An access point was added with wireless G via an old Netgear router-turned-AP.) After several attempts of moving the AP from one cat6 jack to another, I finally moved it to my main level. Oddly enough, so far, so good. Certainly possible the router's radio is pooping out.
What I notice happen with connection issues though seem related to the Note seeing my wireless G, trying to connect, but unable to do so until/unless I reboot my phone. After moving to the new location/jack, everything seems to work OK now (knock on wood).
Having said that... I also think the 3g radio (HW or SW?) is a bit wonky, as my old HTC Hero seemed to have more bars at home, IIRC. Whatever it is, just seems a bit lacking, IMHO.

Sprint is updating to LTE in many markets ive noticed my 3G drops says preparing networks and reestablishes the connection to 3G. I live in Fort Wayne and issue the permits for the tower co-locates and they are close to going live with LTE here so I know thats my problem. I can live with the flakiness for a few more days. I have not had issues with WIFI drops at home.

The same thing has been happening to me here on Long Island. 3g drops and reconnects. Sometimes it doesn't and a reboot fixes it. I also notice after the disconnect and reconnect it states my PRL is unknown. I have done a PRL update many times, a Profile Update, a RTN reset, and a factory reset. This happens on the stock rom and any custom ROM. It's driving me insane!

hmm maybe mobile settings?
Ive found LTE/CDMA setting to be not so good.
Its providing me eHRPD signal which is stop and go web browsing is murder.
CDMA only setting is providing Rev A signal fast web browsing

Sigh, so it seems as if you guys are losing wifi/3g....is it affecting voice radios or LOS/dropped calls?

I haven't been on the phone when it's happened so I couldn't tell you - Nothing like the LOS on the E4GT. When the data connection does cut out it immediately reconnects. Doesn't really impair the functionality of the phone but it happens enough to be annoying. With a 300$ price tag I expect my device to be without defect.

This ^, I have been having lots of problems with the Note 2 and connectivity. Especially with my airvana. Changing from LTE/CDMA to CDMA fixed all my problems including the random drop/reconnects with WiFi.

I'm not having LOS /dropped calls just data creep with LTE/Cdma setting enabled.
Speed test show same data speed numbers as CDMA only setting but when browsing data arrows tend to pause more making for slower page upload with LTE/CDMA setting enabled.
According to Sprint store tech such performance is common with that setting.

I am on CDMA only. I should have mentioned that in my first post. This does affect phone calls too as ill be on the phone and the call will drop and the "out of service area" message comes up. It doesnt matter if I'm on my Airave or not. I tried different prls which doesn't seem to make a difference. I am starting to think there is something wrong with the phone as my girlfriends S3 doesn't do this. Maybe Samsung will release some sort of update to fix this issue.

I made the change back to CDMA only mode this morning and it has solved my WiFi issues as well. I was also struggling getting a GPS lock with LTE enabled. GPS toolkit would show 20/21 satellites found but it would never get a lock. After the reboot back into CDMA mode it locked in 5 seconds.

Hopefully your issue isn't as serious as mine is. I literally just got off the phone with T-Mobile and they will be sending me a replacement phone.

I had this issue with my first G4, but i sent that back due to damaged leather back i have had a couple times with the second one where the wifi acts funky, not a problem but def like wtf moments

No problem with disconnects here.

Mine definitely disconnects and reconnects randomly

My verizon g4 disconnects periodically. Should I be ordering a replacement?

I haven't seen this with my H811 G4.
Sent from my LG-H811 using Tapatalk

Only had the phone a day so haven't seen this yet but i did get it randomly with my G3. I could never figure it out. A quick on/off of the Wi-Fi fixed it quickly. Router is Netgear Nighthawk. About 8 other Wi-Fi devices in the house and never seen it on anything else.

I've been seeing this on my H811. It's nothing major but it does cut off then quickly reconnect after several seconds.

Mine also does this on the T-Mobile version.

H810 here. My G4 seems to strongly - and I mean really strongly - favor mobile data. My house is festooned with wifi access points and yet my G4 often turns its wifi radio off and I have to manually turn on wifi, then manually connect to a nearby access point. As I move through the house, rather than connecting to an access point with a better signal, it shuts the wifi radio off, altogether.
The G4 has shut its wifi radio off while I've been in the process of selecting a wifi access point. It's shut its radio off right after I've selected the access point I want and while I'm booting up the web browser.
Today, at work, the G4 is continuing to seemingly randomly shut off its wifi radio. When I manually turn it on, then select the access point, I find the phone has forgotten the password.
Very frustrating.
As an experiment, I have now shut off mobile data, to see if that will coax the G4 to seek and maintain its wifi connection. But there's no way I'm going to spend my day turning off or on mobile data, wifi radio, etc. I'm already manually turning Location on and off, to preserve battery power.

had wifi issues on the 2 g4's i've had. sent first one back due to damage to back cover on arrival. Glad its not just me having wifi issues

Having these issues as well. Rebooting my router sometimes stops it from happening, but quite frustratingly, the phone gets very hot (and discharges quickly) as a result. Have had a hot, dead phone before.

Most of the WIFI routers have different type of connections G / N / B, The N type is not a !00% compatible with our G4, therefore I suggest you to change to B/N, after I change the protocol, I havent see the WIFI issue so far.

I had Wi-Fi disconnects because I had turned on the advanced option to automatically swap to Mobile data on weak Wi-Fi signal. After that was turned off, the Wi-Fi worked as it should.

I found that disabling ipv6 on wlan0 fixed my slow wifi issue, but still getting the disconnects. (it reconnects automatically though)
http://i.imgur.com/HUDYd71.png - I have a script to disable ipv6 at every wifi connection.
Every instance of SManager is my wifi reconnecting randomly in the house yesterday at my desk.

I have had this issue on my H811 since new. It does it more on 5 Ghz than on 2.4 Ghz, but it still happens. It's more common at home with my Asus router than at work with the Cisco APs they use.
After the latest update I have noticed that the iPod touch I keep in the car disconnects from the hotspot on the phone way too often. This never happened with the previous build, but I also didn't have xposed installed before. Has anyone else noticed any issues with their hotspot?

I got an LG G4 on Friday in the UK and it is running version 10D.
I am encountering this issue and I am finding it extremely annoying - did anyone find a resolution?
It is so frustrating it is getting to the point where the phone will be going back for a refund. It does it at any location with WiFi I go to, so I know it isn't a configuration issue on my WiFi at home.

I'm having this issue too all of a sudden. First thing I noticed was excessive battery drain. But every few minutes it connects to a different ap in my house. Other phones and devices don't do this. Time to dig.

Anyone else having WiFi randomly disconnect and reconnect?

I just got this phone yesterday and so far I just cannot get it to stay connected to my network. No other devices are having this problem. It basically just seems to constantly connect and disconnect from the wifi and also seems to constantly search for other connections as well. I've tried factory reset, cache clearing(which never works as it just red triangle error's me), reset the router, tried to change settings in phone itself but nothing seems to fix it and it's making it impossible to use at home. Anyone have any suggestions?

Same thing here. I went in and turned off all the wifi in battery power saving exclusions. Ain't been home long enough to try though.

I'm having this same issue! My prior daily (S9+) didn't have this issue, and my Pixel 2XL doesn't have this issue. I could be right next to the router and it still does this. Doesn't seem to matter if I'm at home, work, parents house, or a cafe, it still randomly loses connection. Same with my Gear S3. Just randomly loses connection. It's pretty annoying, and I hope they offer a software fix. Yes, I factory reset the phone and it still occurs.

I noticed this only with the 5 GHz band... I will contact LG about it today...

Yeah, I'm having the same issue. My router broadcasts both 2.4 GHz and 5 GHz on the same SSID. Last I'd heard, Android wouldn't connect to 5 GHz in that circumstance, and my G7 appears to continue that trend.
But it still disconnects from the network all the time.

Sadly I have the same issue. I have different SSID for 2.4 and 5Ghz band, and as devil_tear says it's fails only with the 5ghz band. I did a factory reset but issue stills there.
Did you found a fix for this issue?

Had the same problem. Solved by enabling wifi on the battery saving power exclusions in the battery menu.

Had the same problem, was burning through my 4G data at a rate much faster than on my Google Pixel.
So far, adding wifi to the power saving exclusion has seemed to fix the issue. Thank you!

Great suggestion

Tried the suggestion here for adding WiFi to exclusion. WiFi on 5ghz still disconnects and reconnects every few seconds. Only way to keep it connected is putting it on 2.4ghz.
Tried the suggestion with reboots, factory reset, adding WiFi to exclusion and then connecting to the network. My g7 will just not work with it.

Have seen this also, in my case it happens when I am a bit far from the router, it may be the router not having a strong stable connection so the phone see it doesn't have internet. In the points I experience that I have a 5Ghz connection of 0-2Mb but I have maybe 2 bars of connection. Share your opinions to try to understand the problems.

For me I would say it happens more if I have 2-3 bars but nonetheless it happens even 3ft away from the router eventually. what's odd is my note 5 stays connected, my computer, and other phone stay connected on the 5ghz band. All these devices are in the same location so I'm pretty dumbfounded especially considering this is a newer phone than the note 5 lol. I hope it can be fixed with an ota update

I have the same issues. I sent back the first phone for a replacement thinking it was the issue. When the second phone arrived it was working perfectly and then it happened again.
I noticed this happened after I took whatever software update was offered. I went as far to switch providers with different equipment (fibe to cable) but same result.
Made specific 2.4ghz SSID for LG G7 and no issues.

I've never seen this happen. And my laptop and LG are using the same 5 ghz signal.
I think I remember the G6 doing this though

Just came back from my dad's house and I know it's a short test, however he has an Archer a7 connected after his dedicated provided box. I wonder if that can fix the issue?

I have the same issue.
it connects to 2.4Ghz networks fine but the range is very limited when I move to another room wifi reception decreases a lot. However my wife`s S9+ and my oneplus 6 works fine.
Main problem is when I connect to 5Ghz network it starts disconnecting and reception is even worse than 2.4Ghz. S9 and Oneplus connection is still fine at 5Ghz
I tried to change the 5ghz channels on the router but no luck and I exclude the WIFI from battery saving apps still didn`t work.
I have to use 2.4Ghz and the reception is not as good as other phones

Wifi seems stable for me, except wifi calling. That would crash at connection or even mid-call sometimes. I'd have to reboot to make or receive another call. Some sort of server error. Turned off wifi calling and no issues yet. Didn't notice Ed it anyway since 4g is really strong here.

After the newest update on my phone, taken today Oct 4th, 2018/my random WiFi disconnects haven't been happening at all on 5ghz. Also, the signal is about 3 bars larger now in the same location it used to be dropping out constantly. Hopefully it stays this way.

I was coming in to report something similar. I've got the US T-Mo version and just got the G710TM10K update yesterday.
WiFi stability has massively improved. Disconnects are almost completely nonexistent now. I haven't noticed that the signal bar is behaving any differently, but that doesn't mean a whole lot. The update was fairly large (over 400 MB), so I could see new firmware playing a role.
Could anyone still on G710TM10G post their data from Software Info to check if the baseband has been updated? Here's mine from 10K:

WiFi Issue

S20 Unlocked from Samsung.com

Issue:
When on home WiFi network, the S20 does not load images in apps such as Facebook, Instagram, etc. Slows to a complete crawl.
If I test on fast.com, I receive normal home speeds on mobile of 200-400mbps
If I turn off WiFi, performance immediately returns to as expected.
Any ideas?
Router is Netgear XR500

Tried turning IPV6 on - in router settings. No difference. Turned it back off.
System web Viewer had an update. Updated. No difference. Disabled it. No difference.
Those two apps still wildly underperforming on wifi.

Try it on a different wifi connection outside of home? Same results?

Bringing back zombie thread.
Was a fix found?
My 20+ is having problems with wifi slowing to a crawl after just a few minutes.
Just bought a new router TP-Link AX11000 and it started so I thought it was the router but everything else on wifi in the house gets expected speeds my two 20+'s not so. I think it has to do with WIFI 6. If I stay within 10ft of the router everything is fine after that... I go in my bedroom 30ft away and have -63dbm signal strength and I can run a speed test and get 500mbps down try again and it will start at 500 and slow to around 45 try a 3rd time and and I barely get 4mbps 4th time and it's 0 with signal strength still at -63 on all of the test in the bedroom my upload will be 45mbps.

after a lot of testing with battery settings and things on the phone found out that my slow wifi was due to 2 settings on the router.
first in your router disable WMM, this made my s20+ use like 30mbps max in my case. now list my wifi 5ghz as +800mbps
seconds, disable ipv6 on the router. this made my phone ultra slow to everything. like play store hang on app updates, google drive take forever to load every single photo, like is taking forever to get the first reply from the server.
with that changed now the phone works at full speed on wifi. play store updates are shocking fast.
so lame that a flagship that cost nearly 1 thousand dollars have to disable things externally to work properly. no other phone or device works bad with the previous config of WMM or IPv6. I have a Linksys WRT1900ACS.
Hope they fix it with a software upgrade.
