Hi all,
Not been around for a long time so its great to be back
Recently got the Z1C on Contact, frankly its the biggest regret I've had with a mobile device.
Is anyone else having WiFi speeds slower than dial up?
My download speed is < 250 KB's
Any1 else had this? If so does any1 know a fix?
Thanks
I don't have that, neither on 2,4GHz nor on 5GHz. You could try the unofficial DooMLord kernel, it mentions "custom built wifi wlan modules", dunno if that helps.

I'm not currently looking to Root/Unlock/Flash anything.
I'd just like my Stock Z1C to actually work with WiFi.
Its not exactly difficult, its seriously annoying me now, why is it so slow?
.. sorry just saw my solution doesn't help you and I don't know how to delete a reply...
but anyway, have you tried to close all apps on your phone?

my wifi works great too .. what rom do you use? latest .757 ? download .761 or 757 FTF and try to flash via flashtool .. No need to unlock bootloader or root, but you will lose some data if you don`t make any backup
you have a software problem there ..
sony and wifi is a nightmare.....check if your bluetooth is on?for me i get no connections on 2.4g with bt on

I'll check it out when I get home but I never have Bluetooth on so I'd be surprised if it was that.
I have a gaming router which is extremely powerful and all other devices/phones work perfectly so I know that the Z1C is the bottleneck.
Any other ideas if its not the bluetooth?
Thanks
I've not had any issues with WiFi or BT, which is always on on my phone. I do use 5GHz for WiFi.

Have you tried restarting your router?
Does it go slow with every wifi? can you test it on different wifi and see if the problem is with one type of router?
Don't think I've seen anyone ekse with this problem, although flashing the .757 update messed up my bluetooth (then .761 fixed it).

Thanks for getting back to me
I have tested it on my work WiFi, I don't know whether it is coincedence, sod's law or normal but the WiFi on my Z1C at my work is absolutely rapid!!
I've just updated an app to test it, and it was at around 5MB's which is brilliant for me !
However, work WiFi is a 100MB's connection speed, where as at home I believe its around the 12MB's mark (geographic limitations in place here >.<).
From this I see only a couple of conclusions:
1 - Z1C and my home router just don't get along.
2 - As the WiFi speed is so much higher at work, so is the Z1C
or that theres no relation between the WiFi speed and my device but there is an issue with the Z1C WiFi itself?
I'm presuming its the first?
Thanks again!

Hi there,
I'm still on totally stock ROM.
I've done some testing and I believe it is on every router/internet but is very inconsistent. Sometimes its very speedy, others it will drop to almost unusable speeds.
I think I'ma just get rid of this terrible device, very disappointed in Sony. Here are some of my issues:
Phantom Touches
Unresponsive Touch Screen
Constant Crashes
Phone CONSTANTLY answers in Loudspeaker
Screen will not wake up
WiFi Speeds Totally Unusable

Just update to 14.4.A.0.108. It's also stock, official. You do not loose data while updating and it takes merely 10 minutes of "sitting back and relaxing"
As for wifi issue, did you try disabling wifi optimization fetaure found in advanced settings?

Have to be honest,
I got that fedup with all the issues on the phone, I sold it and bought an iPhone.
(Waits to be shot).
However I must say, iPhones feel very nice nowadays, nice and snappy etc.
But yeah, I'll still be hanging around these forums helping people out etc,

Hey that's a new phone just so you know because this is not acceptable.
Not sure about reclaims in your country but it should be valid in most?
Mine did about the same as my PC/PS4 = 60-95MBps, that is until yesterday
Both bluetooth and wifi are stone cold dead so I though I should reflash my ROM(Aur) and rushed it when I realized whilst doing the same 'ol start guide for the hundreds time I forgot to flash recovery :victory::fingers-crossed:

Happens to the best of us
Got rid of my Z1C, and got an iPhone (SHOOT ME NOW).
I just couldn't get past the myriad of issues.
Hey guys,
I'm getting incredibly slow wifi after doing the kit Kat upgrade. I'm currently running the xKat latest from but have the same issue on other roms. I've tried everything from clearing cache to factory resets to fiddling around with wifi settings. My download speeds have dropped from like 40Mbps to 3Mbps. Anyone else experiencing the same issues?
Thanks!
My wifi transport is pretty bad too. :/. idk y. If i try to upload or download something via wifi to my device, i dont see anything higher than 5mbs.

Having Bluetooth enabled slows down WiFi considerably for me...maybe that's ur issue. Try disabling BT if its on

Never have it on actually so unfortunately that isn't the culprit.
So it actually became a lot worse. I was fiddling around with channel settings on my router and noticed that my speed was horrible on my laptop. I turned wifi off and on on the Galaxy Note and noticed that whenever the Galaxy Note is connected to the wifi network every device slows down to an awful 3.5Mbps. No one else experiencing anything like this?
Mine isn't nearly as bad as what you're describing, but I'm definitely seeing some bad wifi performance. Lots of stuttering and uneven speeds. Also, with my Internet speeds and router, I should be getting a lot higher than what I am.
EDIT: my problem actually seems to be a router problem with having too many devices connected. I disconnected a few and rebooted, and now my Note gets 110 Mbps.

Used 2 have exact same problem with my old router pre N bought a new badass router with all the bells abd whistles and now everyrhing works fine. Well that is without having smb streaming dropping here and there.
Will I just received my Note 4. And the WiFi performance is horrible.
Hey @tampaboy good to see you here from the note 2 thread.
Bad news is locked bootloader and as of now no root.
I haven't had any issues with the WIFI yet. Is it just on your home network or are you having issues with a bunch of routers?
How so? You never had a moto x 1st gen. My note 4 keeps a great connection.

WiFi has full connection and Speed Test shows 20mbps download speed but when I download anything from Google Play it downloads at less than 500kbps
I experience similar issues with Google play via WiFi and Uverse Internet connection. I just assumed it was a playstore/Samsung issue as I'm able to download larger files from a server at better speeds.
Just really hope they unlock the boot and gain root on this puppy. Otherwise I could've just bought a iPhone if I wanted all this security locked down crap.
Sad thing is its way easier to jailbreak ios 7 or 8 than the note 4 is to root it at least on AT&T and Verizon.
maybe you just have a crappy internet speed/router, no issue here at all, or maybe just ask for a replacement
Yes the Wifi speed is absolutely terrible. There are tons of threads / other forums have posted this as well. I've tried 2.4 / 5 Ghz N, G, B all crap on various routers. The Note 3 always gets about 2/3rd better speed. At home I have a 30 Mbps connection and the speed always tops out at about 5-8 Mbps. Garbage. Note 3? 27 Mbps!!! what is going on here?
Please don't be an idiot and ask the OP if their router / internet is bad just goes to show how noob you are.

Why we gotta throw the n word around?
I can only speak for my own experience, but I have found better WiFi performance than my Galaxy S5.
Here's my wifi

Definitely not my router
you can't rely on an internet speed test...
run an iperf host on a desktop computer then run an iperf client on your phone(s). that will be a much more reliable way of testing wireless speed between your devices.

oops my bad, and yes im a noob and I don't care about it, its just my opinion anyways, you happy now mr.perfect?
I have also been experiencing slow downloads from the play store.
funny thing though, galaxy store was wanting me to update my flipboard app, so was google play..
so yesterday I started to update it via google play.. 5 min into it, it wasn't even done downloading yet.. so I canceled it and went to the galaxy store, it was downloaded, installed and ready for use in 2 minutes max.
I wonder if its not on their (googles) side somewhere..
Yeah its weird everything else downloads real quick like normal besides from Google Play Store. The Google Play Store downloads normally if I use my data, only really slow over any WiFi network.
I wonder if it's something that AT&T put in the phone so you turn on Download Booster and use your data with WiFi?
Except download booster is "hidden" on the n910a version of the note 4. You have to find the settings through nova and widgets.
Sorry to hear your still having the problem. I haven't seen any slowdown over wifi yet.
I've also noticed WiFi on this is horrible that's forever for pages to load or even time out when on apps. But downloading is fast. My s4 doesn't have any issues not sure if it's hardware issue or software but it's annoying.
Sent from my SAMSUNG-SM-N910A using XDA Free mobile app
No problems on my end. Works great at home and on campus.
Hello I'm new here, well my friend suggest this place to get help for my phone. So the problem is, when i turn on my wifi using my SMT705 it connect then after awhile after playing COC , Brave Frontier the wifi seems like to disconnect on its own. Does this problem have a solution. I've been googling about Wifi problems, some said dial *#0011# then click Menu click Wifi then, ON button will appear after that press it to turn OFF. Well i've been doing the same thing over and over again, its not working. My Phone Wifi problem is still the same. Is it my phone or my WIFI HOTSPOT ( using ST15i Mini as WIFI HOSTPOT ) Old phone. So if there is a solution to my probelm, please reply to this thread and show the solution to my problem. It's hard to play Clash Of Clans, always disconnected xD
One more thing, my laptop doesn't have the same problem . Not useful anyway. Haha
I sometimes get that - wifi drops whilst playing CoC. Is your tab getting hot at this point? I think sustained heat is bad (for any device). I havent found a cure - but wifi comes back after 10-30s.
If it was me i would try someone elses wifi just to see what happens....or if not possible get a usb wifi adapter into your laptop, make a bridge between your internal wifi and usb wifi, then create a wifi network with your laptop and connect your phone to it...but it would be easier and tell a lot more to try another persons wifi....overheating does cause unstable wifi connections...happens to a laptop when the wifi chip becomes faulty and overheats.
I want to see how

You're using mobile data through a wifi hot spot on an old device to play games ?
I pretty much think you've answered your own question there.
I am getting really bad wifi connections and the phone is very slow at browsing refusing to load pages fully. Running Speedtest by Okla says "network communication issues". I get this problem on wifi in public areas and at home. It does not seem consistent. I got so fed up I factory reset the phone. I connected to another wifi router at home and so far everything seems fine. All other devices work fine with public wifi and wifi router at home including Samsung J5 and S4. Any ideas?
Stock rom? Orginal?

I have sometimes wifi is reconnecting, but most of the time I have a good connection.
I'm having weak wifi reception with the A5. When placed side by side with S4 and S7, the A5 has the weakest wifi signals. Speedtest confirms this as well.
Yeah, definitley weaker reception, i compared to my Htc 820 and Sony m2 aqua and it was pretty weaker all of them are on stock roms.
Well, me too. Weak reception when just a littel away from the router. Randomly loses signal force, can't see any router, then, connect again... It seems to get worse when heavy using internet, like watching YouTube videos... But near the router, everything stays normal... My moto g 2014 never had the problem and I'm in stock rom too...
It strangely seems to be YouTube app who causes problems, because when I stop watching videos the signal force get actually more stable, even full in places it doesn't get full when watching YouTube...
But it still seems to suffer from some instability at its natural... When I tap play in youtube, the signal drops to almost zero...
I would like to know what is happening, because it isn't a cheap phone, and even moto g 2014 has got a better wifi
It also seems that demanding wifi in general causes signal to get weaker... I never saw something like that, signal strength doesn't get affected by use, only bandwidth...
Any other experience?
Similar issue with my A5
I recently bought an A5 2017 aswell and my phone also has HORRENDOUS wifi , not just that but for some reason it would randomly stop reconnecting and stop showing the wifi router or anything and the wifi connectivity doesnt turn on , and then if restart it but it would hang mid restart and then id have to hard reset it by holding the power and volume-down button , and this whole procedure happens like once or twice a day so ita really frustrating. Especially because this is a New phone btw, my wifi is perfe fly fine because i ha ve other technology and have previously used many huawei phones which have perfect connectivity and this was my first experience with Samsung, any help would be much appreciated thankyou !!
I am having the same issue as the person above. Pages will refuse to load until i turn off wifi or refresh the page. There are duplicate posts coming up on facebook. Like 4 or 5 posts repeated before new ones. Twitch constantly buffering. Tried on mine and parents wifi with same result. Both were always and still are fine on my note 4. I have 2 weeks to return it to o2 if its faulty or is it just a phone with bad wifi in general?
Edit: i think the facebook thing might be a facebook issue as its happening on my note 4 too but everything else is specific to my a5.
