[Q] WIFI Speed Issues - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hi Folks,
Looking for some help please, my wife got the new xperia z1 compact last week but has been having issues with it since she got it when connected to wifi.
The problem is the internet connection speed is less than 5mb when connected to the wifi, now the internet in the house that the issue is with is 120mb connection and I have tested several other smartphones, tablets and laptops and everything else is working fine.
I have tried deleting the wifi connection and reconnecting it made no difference, we done a factory restore of the phone and it made no difference either.
We then took the phone back got a replacement handset and brought the phone home, and guess what the exact same issues still even with this new handset.
any ideas please folks as this is really frustraing 4G connection is faster when she goes outside

Can you be more clear. Is the connection speed (wifi) only on the phone 5MBit/s or does the connection speed of the whole wifi network drop to 5MBit/s when your wife is connected?

The whole wifi network is fine and stable its only the phone thats not able to get above 5mbs
The strange thing was the replacement phone tested fine for speed as soon as we unboxed it but 1 hour later it was right back to where we started from

How did you measure the speeds? With the app 'Speedtest'?
How many bars does the wifi connection show on the phone? Is it possible that the phone is downloading data in the background?

yes I used the speedtest app to check the speed, the wifi signal shows as full strength on the phone.
I have checked to see if there was anything running in the background and there was not
I also checked this over several days incase it was a data or update that was happening to the phone but still no change

Well that's weird. And another phone (on the same spot) has faster connection? Have you tried on different wifis (e.g. at work)?

Yeah tried other phones and a tablet and all working fine
Unable to connect to a wifi at work as it's locked down
No other open wifi connections avail near me either just now

Ok so just wiped the phone again and set up as a brand new device
New google account etc
Only downloaded speed test app and everything was looking great and the speeds were 50mb
Then the phone updated infoeye and since that update was Downloaded and installed the wifi speed is now back to no more than 5mb

Then try to disable infoeye and test again. Speed should be high again if I am not mistaken.

Tried that and made no difference. Phone returned and the wife has gone back to a different handset which is working

They can add as many gadgets to the same wifi, the Z1 Compact isn`t meant to support more. I tried it on different wifis, in different towns, it`s almost the same thing

What do you mean? I am on a wifi with atleast 20 other devices and I don't have any problem.

i got a pretty similar issue. It's not only the internet-speed, it's wifi-speed in general. Tried to copy at 200 MB file from my NAS via wifi to the phone. Speeds go up to 2 MB/s for short, but suddenly drops to about 300-500 kb/s and stays there. Copying the same file to other devices (tablet, Laptop, HTC One) runs with 2,5 MB/s stable.

Try/internet speed Master from play store worked for me

Seems there are some wifi performance degradation with some WIFI 802.11g routers.
I have 1 router which I could not reach more 2 mbit, no matter of signal.

[Q] Slow wifi on CM9

Yesterday, i have unlocked and rooted my phone to put CM9 nightly on my galaxy nexus[GSM]. Everything works fine but i have one issue, the wifi speed is really slow on my phone.
this is the rom that i flashed on my phone.
http://forum.xda-developers.com/showthread.php?t=1398495
I have tested on speedtest.net and i am getting less than 0.5mpbs. I have looked over my router and other devices, they are getting 5mpbs. Is this an issue with CM9? On stock settings for the nexus i get 5mpbs.
Is there a fix around this?
What is your broadband connection rated at? 5/10/15/20...mbps? If you are rated at 15 or 20 and your only getting 5 on other devices you could have a router issues.
Does the speed get any better when you are within 5 feet of the router?
Do you have multiple Wireless Routers/AP's?
there is no difference if i am beside or 20 feets away from it. I still get less than 0.5 mpbs. There was no issue when i was using the stock version of GNexus 4.0.2.
I only have one router.
I have managed to fix the problem, can a mod please delete this thread?
I have the same problem. When I restore back to stock, the problem goes away. I do have the FD01 radio firmware installed.

Hi folks
I was having the same problems. I just upgraded to 9-20120511-NIGHTLY-maguro and my wifi issues have gone.

Try rebooting your router. I've been using CM9 for weeks now and the only time I've had issues were with my router.
This isn't even the fastest.. just a random test. CM9 Nightly 5/11.

I have the same problem after I assigned my phone a static IP on my home router. Search on MAC randomization for this issue. There are several kernels that fix this. I believe Franco, Trinity, and Imoseyon will work. I wish the stock cm9 kernels would get fixed for this issue.
Sprint GN, Tapatalk
Do you have some sort of QoS setting on your router keeping it from providing the speed to certain devices or something like that? I agree with the others, first thing I would do is factory reset my router.
Having a similar issue my epic is doing 25mbps on a 30mb line but both of my gnexs on different roms are only getting g 10-12????

I've also noticed that my Wifi performance is seriously degraded and very slow. At first I thought it was my connection, but further testing narrowed the issue to my Gnex only. I get very long 1000+ms ping times using the speedtest app and get a stuttery 1-2mb/s down and up, when every other device in my house (6+) is showing upwards of 20mb/s down and 2mb/s up. I have replicated the horrible ping and download times from various wifi hotspots.
To test further, I reverted to a backup nightly with no change. I went back as far as my 04/29 build and the problem remained. Maybe I just didn't notice it before, but I'm not certain. I have even flashed other ROMs such as AOKP and speedtest showed superfast results.

Wonder what AOKP did to it because myself and many others finds wifi to suck on the stock roms.
The wifi problem goes away when i use a kernel that addresses MAC randomization.

Figured out the cause of the slow wifi
I found out what the issue was with my wifi slowness and awful ping times.
I re-installed the latest Nightly and this time I did a "wipe data" (wiping out all of my apps) and my speedtest results were awesome again. Essentially a clean install. After reinstalling my apps one by one, I've been running speedtest each time and found that Doubletwist/Airsync was the cause of my slowness. Uninstalling DoubleTwist/AirSync and then rebooting fixed the speed/ping issue right away. HTH.

Sightly strange WIFI issue

Good afternoon XDA HOX owners,
I'm having a really strange problem with getting on to my wifi AT HOME ONLY.
The phone sees the wifi, registers the strength of the signal, but loses connection all the time. it's the first time I've had this issue with a gadget, and this is the 4th smart phone that's been owned in my household, while using this particular wireless router. there's also 2 laptops, a NAS and an iPad (EEWwwww ) ... and my mates that have my wifi password get on without an issue...
If I turn the wifi on the phone off and on, it works for maybe ten seconds to a minute, and then drops connectivity, but not the signal. I know this because of the little 'up and down' connectivity arrows that run in the CM10 wifi indicator. they go either up, or down or nothing, but the signal is still there.
Any help would be massively appreciated as it's ruining my love for the awesome device the HOX is, especially running CM10.
Thanks :good:
your auntie mable
Gonna bump this thread up because I'm home and it's driving me batty!

I had this issue with my homehub on the 'n' setting. Something just didnt work between the phone and hub. Try changing it to 'g' if its not that im at a loss. My.x would work everywhere else but home properly
Now works flawlessly
My nexus used to fly with the hub. Slightly irritated i had to lower performance purely for my phone. Its npt a massive difference but theres a reason theres a g and a n lol

Thanks mate.
So I've tried that and no luck. Virgin phone support says it must be a 'hardware issue with the phone'.
Any other thoughts?

I'm having similar issues with my Wi-fi at home, tho my connection lasts longer, sometimes 10 mins, sometimes 5 hours+ sometimes all day. The strange part is that when i use wi-fi on the phone alot like some sort of heavy stuff youtube, downloading etc. then my connection drops. I've tried using only N connection and BGN Mixed on 20 and 40HZ channel and N seams to give me the best results, never tried B and G connections since i think those reduce the range of your WI-FI , too bad i didn't go for A B G N router. Anyway could be up to my router or something, every device that uses my WI-FI has same issues with this router. I even took it to the repair center they've done some ping tests and showen me that router works perfect. anyway back home still does those buggy things. If anyone has any good idea please feel free to suggest us.
I'm also having an issue with mine, although slightly different.
My phone connects to available wireless with no problem and stays connected however when I leave that location it stays connected instead of switching back to mobile data. I have to turn off wireless and then turn it back on to get it to switch to mobile data.
Kinda a pain in the arse and really annoying. I've missed allot of important emails since I got this phone due to me forgetting to turn wifi off everytime I leave somewhere with wifi.
None of my previous smart phones had this issue. I'm hoping that if I get custom rom on it, it will work properly,

[Q] Very (very) slow load on home network.

Good afternoon;
This has bothered me for sometime but I normally only use my wifi at someones house or my own in the evening and both times when I noticed I always make note to ask and forget.. So.
I bought the HTC One X about 4 months ago and have had this issue since day one. I recently updated to Jellybean and the issue is still there.
I speedtest on my PC (desktop) 30mb/5mb and using speedtest on my HTC I get 26/5 (all good)
My issue is when I'm using WiFi the loading of pages, pictures.. ANYTHING is very very slow. It'll take me 10 seconds to open say slickdeals.net where as when I'm using my phones Data (AT&T) it takes me about 1-3 seconds. This goes with any site and often it'll time out as well (using wifi)
Disconnecting/reconnecting wifi does help with the connection timeout however the speed issue (of lack of) is still there and taking 10+ for whatever I'm trying to few. There are points where the speed seems normal, pictures load when I click them however I would say 95% of the time sites/pictures each take at least 5-10 seconds to load.
Some info on network and HTC One X
Network:
Sec: WPA/WPA2
Speed: 30mb/5mb
No ports blocked (I even tried DMZ'ing phone)
Phone:
Version 4.1.1
HTC Sense 4+
Anyone have any ideas or need more info? I would love any light into this issue. I have read WiFi issues with this phone but most seem to be with the quality/connection to the adapter and my signal is very good. Thanks all!

Thanks for the reply, Sorry for the late response but i wanted to give a few browsers a day to test.
Same issue on FF/Dolphin Browser/ Default
One thing I notice is that under Settings>WiFi>(My Network)>"Link Speed" shows only 2-6 Mbps. Running speed tests get me often .5 - .8 DOWN and 5.1 UP.
WiFi boost is enabled on the phone as well.

[Q]Wifi problems

I've done some searching and have found some of the dumbest things that make no sense. I have 2 problems. 1 - If the wifi shuts off it will not reconnect to my router. This only happens when the router is on N only (both 2.4 and 5ghz). And 2 - The download over wifi is incredibly poor. I get speedtest results turning back 3mbps down 6mbps up. Why is the download so poor? This is on wifi NOT 4glte. on 4g I see around 13/9 with 3 bars.
I've also tried all the modem firmwares and all were bad except the previous one before the current update. using CSrom
To my knowledge the modem file will have nothing to do with the wifi radio or its firmware.
The connection errors seem to be wpa. Wep or running open and I can connect every time.

Ok well I got the problem solved some how by changing roms. The rom I used moved to graviton so I switched, No problems with that now. Its just the download is terribly slow for wifi. The upload goes higher than the download.
Not to mention I'm not even 15 feet from the router getting 1 bar for wifi.
My speedtest app was botched. I redownloaded it and suddenly 12/5 easily. Not sure if thats the max the GS3 wifi can do but thats where it topped on 2 different GS3. One running stock 4.1.1 and mine running graviton 4.1.2.

My desktop gets 56/5.8 wired. The wireless pcs in the house get 20 - 30 on wifi. My package is 50/5. I'm beginning to think my router and extender both dislike the GS3. My old ass LG optimus was able to get 20down and its ancient.
Ok so it turns out its because my router/extender are dual band? Is there anything I can do besides buy another router? The ones I have are fairly good and I don't want to replace them.

WiFi Performance is horrible!?

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.

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.
