So this is weird. My wife and I just picked up two brand new M9's from T-Mobile this afternoon.
We're able to connect to the wifi with our new phones without any trouble, but the wifi is sporadically slow. SpeedTest shows download speeds around 14.21 Mbps from the phone, but 64Mbps from my laptop for SpeedTest. Google services seem to go really slow:
Google Play application icons are slow to load
Google Now's initial setup hangs at a blue circle loading with gray background
Google Music takes a good 5 minutes of buffering to start playing a song
Browsing to google.com periodically times out in Chrome: "Google CHrome could not load the webpage because www.google.com took too long to respond."
I'm also noticing that despite connecting to wifi, there's still the 4G icon in the status bar - with my old M7, if you connected to Wifi, the 4G/2G indicator disappeared. Is this behavior normal for Sense 7?
EDIT: I've tried the following, and things seem like they may be a little better. I'm not sure which is the potential fix though:
Disable Power saver mode
Disable WiFi optimization
I grabbed a spare WiFi AP that is dual band, 5GHz seemed to go faster, but I'm not sure if that's because it's inherently faster than 2.4GHz
EDIT EDIT: Just kidding, I'm still having issues.
I don't know about the wifi going slow but the 4G icon will stay even if you're connected to wifi. I haven't had any problems with mine going slow on wifi and I have the T-Mobile version also
The weird part is that slowness is too broad... it almost seems like certain services are having issues. I could get to google on Wi-Fi and twitter would update, but Gmail, facebook, instagram, and hangouts wouldn't work.
Disconnecting from Wifi (and reverting to cellular data) "fixes" the issue.

Check to make sure in the advanced wifi settings that Wi-Fi frequency band is set to either auto or 5g. Usually the wifi will have the same name but the 5g will simply say "-5g" after the name. If you are connected to the 2.4g you will be slower. Here is a screenshot of my speedtests on the same network but different frequency.
5g= 209.53 down and 21.01 up
2.4g= 44.77 down and 21.13 up
both on my wifi just different frequency...

Hi all
A search of the forums revealed 5 potential threads similar to this but not quite (not same symptom, phone, modem ...)
Keep loosing mobile data connection...
I have installed X-note 3 and found that my mobile internet is intermittent particularly in Youtube where I frequently have to click "No connection , Retry" or "Connection to Server lost, Retry" and in Play Store and Gmail where the problem tends to occur on a screen unlock after it has been unused for a few minutes - about 3 to 5 mins.
I dont believe this is a ROM issue because I d/l various ROMS such as Revolution, Alliance, PacMan, Paranoid and still I get the problem.
I tried installing all 9 of these radios here: http://forum.xda-developers.com/show....php?t=2044937 to no avail.
Also notice that if I set Network Mode to "GSM only" then this makes no difference to the problem (the default is "GSM/WCDMA Auto" which is what I've set it back to)
WiFi works fine.
Any ideas?
same issue here.
a lot of time trying to know why this happen. and i think it is due to fast dormancy.
the phone usually stays in standby in 3g... when you request some data it will automatically turn h or h+. Here is when you will notice the internet moving.
But unfortunately if you have some.coverage issues you can have this problem and then the programs instantly report no conection. If you insist you will see you can obtain connection. 5 seconds later 3g will appear again
It does not mind you will see the bars of coverage at maximum... if there is no quality signal you will have this problem.
I just have this problem at work. Not in other places.
But if you want a constant connection I recommend to keep for example online music while navigating...this will avoid the issue...unfortunately you will increase your data plan..
Yes!! This is exactly what happens.
So it can't be my specific phone but perhaps a hardware design or software issue. I don't recall this I happening before I rooted
Weird
Fixed it - so far at least
Fast Dormancy is the problem. It was enabled by default and I have turned this off. The connection is now fine and seems to be "always on". For me this is okay because I do not have any data limits or pay per MB for data. I do notice that new connections take a little longer to start (for example, time taken to access internet when opening up an app that is not currently running) . This is not noticeable for apps already running (in the background)
This explains ....

I have a SGH-I747, baseband I747UCDMG2, using CM 10.2 Snapshot M1, and have issues with remaining connected to Google's servers. If I put the phone in standby (pushing power button), when I wake the phone back up, the data arrows go back and forth, and then the connection type goes grey. It will cycle between 3G, H, and H+. It will finally connect, and I can resume my Google services. I'm in a location that gets good signal (current signal strength is -89, and is pretty much constant). Since my number has been ported to Google Voice, it effects receiving text messages in a timely fashion. I know it's not Google Voice doing something weird, as when I'm at home, and on WiFi, I have no issues with text message delays.
It seems to be all of the CM roms I've tried do this same thing. Although, I remember before I rooted and flashed CM, I had similar behavior on Touchwiz roms (I would see G, 3G, 4G, 4G LTE).
I don't mind flashing the newest radio that came with the 4.3 update, but it's a pain to not get notified about a message I received 20-30 minutes ago.
Is this normal behavior for the radio to step down the connection, to save battery, and then upon waking, needs to reconnect to the google servers? I do not have any type of battery saver app installed, shutting down the data connection.
With a * next to this statement, I'm going to say I have this fixed. I had the Voice+ enabled, so my GV texts would be forwarded to my messaging app. I disabled that, and now I seem to be better off. It still does the whole 3G/H/H+, greys out, etc, but longest delay on a text lately has been just 6 minutes, dealing directly with the GV app.
Hey guys am i the only one having issues with wifi, its so painfully slow takes forever to load a webpage forget about watching a video, and no its not my wifi because i have tried several different ones and its always the same slow speeds, ive gone over my data limit twice since i got the g4 because cant you wifi.
is their a fix for this iissue, love my g4 but seriously thinking about another device

Try the DNSet application - I had painful Comcast WiFi speeds, or lack thereof, and running this application before turning on WiFi solves the issue. Not sure if it's just me, but you should know that MMS doesn't work when the DNSet application is running.
What is stopping us from hardcoding DNS entries in the WLAN config now that we have root? Is this possible?

I looked at it, but the app needs to create a VPN to work, which is a whole other can of worms.
Do you have Comcast? I've learned that Comcast rolled out IPv6 out of nowhere, and many of its routers have issues with some phones (my gf's iphone included). I rooted my phone, disabled IPv6, and now I'm back to consistent 50-80Mbps download speeds on my phone.
Before, I would open up the Speedtest.net app, it would take a full minute or more to locate a server, and then the needle for the download speeds would constantly bounce between 0 and 50, sometimes with my phone prompting me that I lost my internet connection, asking if I would like to switch to data. Worth a shot! If you can't root, DNSet does this for you through the VPN, or you might be able to find a way to shut it off on your router.
I don't seem to have any issues with my phone picking up IPv6 over data or a few other routers, though, so I think this issue is more due to some bad firmware on certain modems.
Yes i do have comcast, their is many other cellphones in my house galaxy s5 ,s6, lg g3, iphone 6, none of them have problems but mine, how do i disable IPv6 once i have root

From the G3 after the 5.0 update, the fix was to disable IPv6 as well. This isn't related to IPv6 though, as it only seems to effect the G3/G4. Also, Google "What is my IP" when on mobile data and you will likely have an IPv6 address from Verizon.
I don't know that it isn't related to ipv6; Samsung phones have similar issues and my girlfriend's iphone does as well. I don't think the problem is the protocol itself, but how certain modems (seemingly Comcast ones) incorrectly implement them in their firmware
S20 Unlocked from Samsung.com
Carrier: AT&T
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
Quality of Service is off.
Did you try a reset of network settings under settings?

Just tried that.
Fast.com reported download speed of 500mbps
I was able to download an app at an appropriate speed
It seems to be only Facebook and Instagram that are still showing the issue -- extremely slow load times.
Both work as expected on LTE.

Android System Web Viewer did take forever to update while we set the phone up. I'll see if I can roll that back.
I don't have any issues with any of my other android devices on my router - but I'll also check IPV6 settings.

No luck trying this.
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?

I tried it on another phone's hot spot and could not replicate the issue.
I guess that means it's a problem with the router settings. Not sure how.

I have the same phone, carrier and use wifi at home as well. No issues, sorry you're having problems....
Maybe a full wipe?

Hope you sort it out sir, I normally don't get unlocked on ATT due to losing WiFi calling but I get a better signal now and you can just call to get visual voicemail fixed if yours doesn't work right away so I'm loving it....
I'm sure you'll love it too once you get it sorted...
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.
I recently bought a Samsung S22 and for the last couple of days now I have started to see issues with the network connection (Not Wifi). I will see 3 or 4 bars that show signal strength with 4 or 5G, but when I go to open an app like TikTok, Facebook, or even Google Chrome the app just keeps loading like it isnt connected to the network. It seems like if I wait it out things start to work again after some time. At first I thought it may be an issue with the phone trying omegle xender to switch from 5G to 4G but now I'm not so sure. I wanted to check to see if anyone else is having this issue?
Same issue here, on Mint Mobile (T-Mobile MVNO). It usually happens while I'm driving or in certain buildings. Toggling airplane mode off and back on usually resolves it for me.
