WiFi Issues

Hi Everyone
I looked and I could not find info on this issue. I have just used WiFi at home in the past with the Note 3 and it was fine. Here is some history of the changes:
- Old home WiFi was single band wireless N (53mbps) with a second repeater hot spot. This worked well with the Note 3.
- Had issues with the router so I upgraded to a dual band ac router and removed the second hot spot. So now it is just the new router for the whole house.
- Issues now - receive 2 bars at the far end of the house and basic WiFi is OK. Watching You Tube is an issue and it loads, plays for a few seconds, loads more etc.
I don't see a way to tell if I am on ac or wireless N. I was going to try to switch to wireless N and see if that helped but I can't see a way to do this? This router is way faster than my old one so I thought speed would not be an issue. no one else is using the wireless in the house. I would think that 2 bars would be strong enough? I think that wireless N would have a better range so that is why I wanted to try that. I am assuming that I am connecting to ac. Any thoughts?
thx in advance

AC routers have two separate ssid's. One for b,g,n. And another for 5G band. The 5G band default ssid is the same as the other with "5G" at the end. 5G band doesn't have good range, but it has faster speed between connected devices. 5G won't have faster internet unless you have a 100mb download speed. Which is unlikely. So your YouTube issue is either your modem, or a Qos setting in the router. If your router is at default settings it's definitely your modem.
You might be able to get more support on this subject thru a forum for your router, or modem.

why not use your old router from your old home as a repeater? wouldn't that work?

That's called buffering and it's due to low thruput (which is different than speed). It can be caused by low signal strength (due to distance or to the signal haveing to go through too much along the path), noise between the router and the phone, interference with someone else's wifi signal ...
You need at least a couple of apps like Signal Check Lite and Wifi Analytics to see what's going on. Guessing isn't going to give you a solution.

moto x pure att WIFI kills data signal

Issue: While connected to my EA6900 (1900 AC) linksys wireless modem my data dies. If I turn off wifi, I am able to call out, (although patchy), get texts, and use android services. As soon as I turn on wifi, these services all seem to shut down. Although sometimes some data is able to eak through.
Background: I am using a Moto x (2014) Pure Edition on the AT&T Network. I have confirmed time and time again that wireless works on my network, I have a full wifi signal and decent LTE signal (unsure how strong -- it shows 2-3 bars). I had this problem initially in 4.4.4 and it persists in 5.0 (I updated to see if that would fix the issue. Previously I had and HTC One with no issues what so ever. Reboots do not fix this issue and ATT has told me it is not their problem.
Hypothesis: I think the Moto X 2014 has problem connecting on the 5ghz (duel band) or AC networks. I have noticed while at work or other locations, I have had no connectivity issues with wifi on. I am pretty sure they are using standard 2.4ghz G and or N connections. I believe that the phone is unable to switch between the range of bands and causes it to lose data connectivity.
Has anyone had this issue or can anyone correct it?

I don't have an ac or 5ghz router so I can't test this. Have you played with the WiFi frequency band under advanced WiFi? You can force connect to 5ghz or 2.4ghz.
You could also turn off ac on the router configuration page to see if you can connect on n.

When I have time I will play around on my network to try and force the connection to different protocols. I have an AC router from EnGenius it's their ESR1200 which is a consumer grade device but pretty nice over all and was a steal at $60 over on Amazon:
http://www.engeniustech.com/home-networking/routers/16742-esr1200
But will try a few options. Right now I have it connected to the 5ghz band w/o issue. I can add I have long encountered issues for Android when moving between wifi networks. It has always been prone to struggling to juggle connections, even when switching nodes on a mono-SSID network. I can trace my issues back to Jelly Bean. But it seems like you are seeing something different.
If I find anything I'll post it soon as time permits, busy week for me at work or I might get lucky and just die in my sleep.
EDIT: For giggles I forced a connection to the 5ghz side and sent some texts as well as a couple calls w/o issue. Was able to receive as well. Mode is .11n of course and a solid 433mbps network connection speed

This is where my hypothesis really dies... I have attempted forcing 2.4 or 5ghz but both failed. The other option is the phone doesnt play nice with the EA6900... which is seemingly supported by the fact that my phone hasnt had any issues while i am connected to my parents house for thankgsiving. They are running 2.4ghz at a blazing 65mbps (i usually average around 400 at my house on my ea6900). Could it be the AC modem? One other thought is chromecast is somehow interfering with my phone. I will need to try removing chromecast when i get home to see if that works, but at this point, i would find it hard to imagine.
This is literally driving me up a wall.
EDIT: So I am at home at it has been running better but just now it has decided to seize up. Showing same info... 2.4ghz 65mpbs same network... full bars.... att shows 3/5 bars but doesnt say LTE or H or anything..just ATT (pretty sure thats normal)

There are a bunch of comments about it overheating and dropping signal repeatedly. I would think about returning it under warranty.

I wanted to blame my router very badly... however i have never experienced any drops on my laptop -- unless my laptop somehow deals with drops better than my phone...

Wifi blows on 10.5

I gotta tell ya, id absolutely love this thing if it wasnt for wifi issues. This thing drops connection all the time and lags so bad its awful. Done everything I read to do, freezing or deleting apks. Think it would be a home run if it wasnt for the wifi.

I've had mine a few weeks and I've never seen it drop wifi.

Never had a problem with the wifi, but the lag is horrible

Did you messes with your kernel?

I've got an 8.4 but I'm assuming the WiFi hardware is the same??? I've had mine for several months and never dropped a connection (except when my router went down) . I use it mainly on a 2.4 Ghz network at work. In my office I'm on the other side of an elevator shaft from the access point so reception isn't good on any device in my particular location - but it works and even there never dropped a connection. At home I've got it on 5 Ghz and where I typically use it the signal is very strong. On speedtest.net it matches the speed of my desktop PC which is wired into the router....so it's getting all my internet connection has to offer (service level is 30 Mbps but speedtest.net usually shows 32 - 35).
I'm assuming you have already checked the obvious things like signal strength? Does it drop the connection in some locations but not others? Does it make a difference what router or access point you are connecting to? Interference from other WiFi networks or (if using 2.4 Ghz) other devices like cordless phones?
Try installing WiFi Analyzer (free in the play store). It will give you a real time chart of your signals strength for all access points it can detect on both 2.4 Ghz and 5 Ghz. For example in my Culdesac I can see at least 6 other access points with pretty strong signals (all my immediate neighbors). At my office, on the side of the building facing an appartment building on the opposite side of the street, I can see at least 25 2.4 Ghz access points. Amazing how many are named Xfinity WiFi or Linksys . On the other hand, on the 5 Ghz band in my home I only see one access point other than mine.
Try manually setting your router/Access point to a channel no one else is using. Switch to 5 Ghz if your router has it or buy a new router if it doesn't. This band is a lot less crowded, at least where I live. If your signal strength is low in the place you want to use the tablet, try moving closer to the router to see if that helps. If it does, consider moving the router or getting a second router or repeater.

I use to have problems in my home with 2 things.
A baby room monitor - REALLY tore up my wifi all over the house!
A set of wireless rear surround speakers was a problem for about a day. Lucky for me they have the ability to change the channel they use. Wipped out my freq counter, found out where they were and moved them to ch 11. Unit isn't marked as to what 3 channels you can select from. So the freq counter helped me find where they were and where I could put them. After I got them on ch11 I moved the router to ch4 as there was no one using it near by. Problem solved and have no wifi problems at all with the Sammy.... Matter of fact my router sits on a cabinet 6 feet off the floor. I get coverage over my whole .7 acre Ponderosa while listening to music riding the mower!

my wifi seems to drop once in a while too but i think its the crap router i use.. not sure
i also reset my tab and that helped.

Another thing I just thought of that you may want to check.....
Make sure no devices are fighting with each other trying to get the same address on your network. I just went through this last night. Once resolved, no problem.

A lot of this sort of problem can be fixed by going to 5 Ghz - which may mean a new router if you are using a router that isn't dual band. Most of those other devices in homes (and in your neighbor's homes too) are on 2.4 Ghz so there are a lot of things that compete for that spectrum that aren't even WiFi.

No WiFi issues here

No wifi issues here. I was on stock for about the 1st 30 days on the device and have rooted and installed various ROMs since. I would argue that this device has better wifi than other devices in my house, though my router is not AC so I have no comment on AC performance. I do have an issue with N 5 ghz networks not being seen right now, but that is something I induced.

Too many factors to consider but I can say if other's haven't had issues than it's likely something else.
Distance from access point
Access point's distance from other electronic equip.,
Wireless channel
G or N connection
latest firmware on wireless access point
cabling on AP
trying a different Access Point or wireless network altogether (coffee shop, etc)
wireless sucks to troubleshoot. Constantly changing settings until some magical combination works for all of your equipment.
like to connect my Nexus 5 to wireless N I have to set my 5Ghz channel to be on upper or lower frequency band or something- can't remember which it's supposed to be, though. My PSP needs the 2.4Ghz radio set on a b/g mixed setting. That's the only weird wireless settings I've ever needed to actually get specific devices to connect.
if you're looking for advice we'd need to know the model of your router/access point, though I'd probably go look at a forum where people talk about it.

Hi,
I am wondering, if anyone else having this problem...
My best available 2.4 ghz wifi channel is 13 (2472). If I select this channel my tab does not find the wifi anymore ("out of range"). All my other devices are running on channel 13. All other channels working.
Tried it with stock rom + stock kernel as well as with stock rom + latest UpInTheAir kernel, iron rom + UpInTheAir kernel, iron rom + stock kernel, factory reset, clean flash etc...
Can anyone confirm channel 13 is working on this tab?

Thx, brgds!

WIFI slow / disconnecting

Hi
I received my 3T yesterday. I am having issues with WIFI
WiFi network drops frequently and the mobile data is used for some time and then WIFI is connected again. See attached .. This happens even when moving between rooms of my house
I think this happens when the mobile wifi changes from 5GHZ to 2.4GHZ when I move away from router
I have updated to OxygenOS 3.5.4 as soon as I received the mobile
The signal strength of the 3T is also very low
I have a 2 year old moto X 2014 and the moto beats the 3T at every place in my house
The signal strength and the wifi speed both are better in moto X
I have checked at various places
I have wiped the cache. Tried changing 2.5GHz to 5GHz
Changed Channels.. Tried all the things that I could find on the internet
But still problems
So is this a hardware problem and should I ask for a replacement? Or is this some Software bug which can be resolved
My router is ASUS RTN66U and a lot of other devices work seamlessly on that router and hence pls dont suggest to change the router
Awaiting replies
Regards
Ajjaykummar

I think this is a bug related to 3.5.4. On 3.5.3 my WiFi worked a lot better, but LTE Advanced is faster on 3.5.4. You can try a custom rom or downgrading, there's also a leaked OxygenOS 4 rom out.

Do you have wifi issues now when u have 3.5.4
I don't want to install new Roms. As I may have to return it in case this is a faulty piece

I'm having the exact same problem. I stream a lot. Very annoying when music video or gaming gets disconnect so often. My Galaxy Note 4, & s6 works fine.

yes, it started on 3.5.4.

here is a screencap of the issue
You can see in the screen cap that the mobile is connected to ASUS5 (5GHZ)
Then as I move away from the router the signal weakens and then the wifi disconnects .. and then it connects to ASUS (2.4GHZ)
Earlier it was connecting to ASUS but with a exclamation mark (without internet).. I waited for 15 minutes but it did not connect
Then I would connect if I switch off and on the wifi toggle
After that I did a factory reset and now you can see the screencap
It connects after a minor delay.. So is this alright
My other mobile - Moto X 2014 simply switches instantly from 5GHz to 2.4GHz and vice versa.. not even half of second is taken on moto x

Give the device a static IP use 2.4 network as it's more of a long range band. I tend to use the 5 band for stationary stuff. My WiFi works fine but all my home devices have a static IP.

This are the things that I did
1) Factory reset
2)Use Legacy DHCP client (under Developer options)
3)Disable Smart Wifi switcher (Advanced Wifi setting)
4)Static IP
This seems to solve the disconnection issue .. I still feel the wifi signal is weak compared to my other devices
Hope this helps someone facing the problem
regards

I had the same Problem on OOS 3.5.3/3.5.4/4.0 at the OnePlus 3T.
I tried every Solution on the internet and nothing worked for me.
But after i looked into my Router-Setup i saw the DHCP Section where i selected 'Renew DHCP every Day'
>>> Screenshot what i mean - imgur.com/KakQX3i.png <<<
After that it works perfect. No connection-issues anymore.

mine is already one day..

I thought it was resolved... but again I noticed slow wifi speeds
thinking of replacement

haven't had the phone long enough to experience disconnects but wifi is definitely slow...
I have a 200mbps connection, getting 160mbps on desktop with LAN cable, 110mbps on my OPO, only 50mbps on my OP3T....
all tested through speedtest with the same server location.
OP3T is chinese version flashed with oxygenos 4.0.1
edit: later tested again with OP3T getting up to 90mbps but still 20 less than the OPO

I have same issus like lajay. The Galaxy S7 from my wife works perfekt in the same Network!

Wifi issues please help me !

I literally just switched from the Note 9 to this phone again because I loved it the first time....
But then after using it for a few hours I noticed the wifi would disconnect and reconnect and then when it did reconnect it would say "connected, no internet" and it's been like that ever since ...I had to connect to my slower 2.4Ghz connection instead of my super fast 5Ghz one because that's the only thing that is working....doesn't make sense because EVERYTHING else in my house is working perfectly it's just this phone....any fixes or should I just get rid of this phone.....

Does it work with other wifi, like your workplace, library, etc.
Most likely, you need a new router or need to update firmware on your wireless router.
It happened to me before with my other phone and my new router fixed the issue. Actually, it just happened this weekend, I cannot connect to hotel wifi with my Razer 2 phone and my wife can (Huawei P30).

I would keep the phone because otherwise it's a good phone. I was having similar issues with the Official PIE MR1(version 3110 in the "about phone" section) it got better over time but not by much. I have a very old 1st generation 5Ghz dualband N router, but it works great on my campus network with their 5Ghz AC routers.
If you're feeling brave then you can downgrade to the older Oreo firmware which seems to have much better wifi and cell connection, or you can try using Arter97's kernal via a similar method if you're attached to Pie. There are plenty of guides on how to do the downgrade/Kernal change and all the files are on Razer's site or here in this device forum for it, so it's not hard to do if you're good at following the directions. I'm still testing the wifi performance changes on Arter97's kernel, but I'll update this reply if there's anything conclusive.
Aside from that, your options are: Try upgrading to an AC wireless router that supports Beam-Forming at least, just waiting it out to see if your phone gets better at connecting(maybe even try moving the router to a different spot), or as a last ditch try replacing the phone with another RP2 or another brand...

That may be because your home wifi can't connect to Google server, China is very common, but it doesn't mean you can't go online.
