SpeedTest reports lower speed

I used 2 apps to compare. SpeedTest.net and Xtremelabs Speedtest. I have a 2Mb connection and it test correct on my laptop both wired and wireless but with those 2 apps, my DHD reports ~223Kbits. I run the test several times (around 20 times) and it always shows similar results. Only one run which I did after returning home showed 2Mb. Never saw the same again.
Anyone noticed the same? maybe it's the way those apps measure or is it my phone?

You tested what ? Your phone connected via WiFi to your home internet, or your phone GSM/EDGE/HSPA connection ?
The home internet can be explained by downloading something else through other computers on your network or by lower wifi speed negitiated between your phone and wifi router.
If you measured your mobile connection, it could be that you simply don't have HSPA inside your house and it drops to EDGE or UMTS -> sub-300kbit speeds.

thanks,
I already know what you mention.
I test wifi connection. It is supposed to check data transfer rate between my local wifi connection and the Internet. I do the same on my laptop at same location and get 2Mbits.
My mobile connection here is unstable=(sometimes GPRS sometimes 3G) so I won't bother to test from here. I am only concerned about wifi results.
Are you getting those correct?

In case of WiFi, there are many factors which can slow it down. But since you are using the WiFi on your laptop too, we can exclude factors like interference from other WiFi networks or any other factors which could make your connection to your router problematic.
This brings it down to the phone itself. Now the questions is - do you use any kind of WiFi security ? If yes, can you turn it off just for test (yes, i'm asking you to have a unsecured WiFi network for a while). This way you can exclude the possibility that it's the encryption which slows you down. If it will speed up, your problem lies in encryption, and that brings up the question if you have USB debugging enabled or not - you should have, as it fixes the 100% CPU usage bug. If your CPU is used up thanks to this bug, then of course all encryption is slower, which means your data transfer is slower.

Strange, you know what? I connected to USB in order to sync and verify USB debugging (it was on anyway) but after sync, I run the test and it shows above 2mbits but one time it showed 1,2Mbits. The same goes with xtremelabs speedtest.
Now, I can't tell if it's due to the usb connection. I restarted my phone earlier anyway and it still measured slow connection at the time that my laptop was measuring high.
I ran the test so many times that I am 99% sure that the only difference this time was the connection to usb for sync.
I can't exaplain this, I don't know if you can

Then, after a while I try again and it goes down again. I sync but still stays down so that's irrelevant.
I perform the same test on my laptop right after this one and from the same location and it's always high.
I don't know how to explain this

WiFi disconnects often?

I'm really happy with the phone so far, but my wifi disconnects fairly regularly and I keep getting a force close on the SMCC Process (whatever that is). Anyone else having problems?

I just read the thread below this and that issue seems similar.
EDIT: I tried turning off the smart wifi, but it still loses connection. The phone still shows that it's connected to whatever wifi signal, but stops downloading. This happens both at home and at work, so I don't believe it's related to the router itself.

I'm seeing the same issue on mine as well. Noticed it last night playing Pandora via wifi. Would play like 3 songs then nothing. I would have to toggle wifi on/off to get Pandora playing again.

Sounds like basically the same thing. If I wait long enough, it comes back on its own, but it's faster to just cycle wifi or airplane mode once. It's fairly frustrating, and I even found myself just using 3G to do things last night instead of Wifi.

seems to be a known issue in other S4 forums:

Mixed Mode WIFI
I had this exact same problem with my EVO 4G LTE, the problem was the mixed mode WIFI. (B,G,N). On the EVO it turned out to be an easy fix because there was a setting in the WIFI menu to force either B or G. As soon as I selected one mode I had a solid internet connection. The problem here is there does not seem to be an option in the S4 settings to allow this. I have been trying to force single mode on my router to see if that will fix it but my router will not allow me to turn it off either. Pretty serious bug I would say.

WIFI worthless on brand new S4

it doesn't do it as often as it did with the SGS3 though

I really wish I could find a resolution to this. I'm thinking of wiping my phone and starting over to make sure it isn't an app issue, but man that's a lot of work.

Im having the same issue as well.. Im almost positive its common issue and i would expect it to be addressed in the next OTA

The common link seems to be DLink router. We have a Cisco Linksys router and it stays hooked up solid on that.

I have an Asus router. Don't know if there are usually problems with those or not, but I haven't had any prior issues.

I have a Cisco e4200 stock and a Asus running ddwrt operating as a wireless bridge to extend my network. I had to turn off mixed mode on both devices to resolve the issue. Hope that helps.

I have the same problem but I have Netgear routers. The one at my house works fine, but at my other location. The wifi drops.

Same problem on dlink

Adding my 2 cents because I have 2 S4's that I've been testing with and I'm getting mixed results... my first post here so I hope I'm doing this right!
I have 2 wireless routers at home:
- DLink DIR-655
- One provided by my ISP (Bell Canada; not sure of the model at the moment)
The DIR-655 is troublesome for BOTH S4 devices; they stay connected for a few minutes (or longer in some cases) but will always end up not transferring data even though they show as having a very strong signal. Turning wifi on/off always fixes the issue for a short period of time.
Knowing that there seem to be compatibility issues with the S4 and DLink router, I switched them both over to the Bell router. Now only one of the devices has the wifi issue described above.
I found it odd that changing the router being used fixed the issue for one of the devices but not the other. I'm now questioning whether one device has a hardware issue or not (doubtful on this, but worth questioning).
Both S4's have the most up-to-date firmware as do all of the routers in the house. No other devices (iPhones, laptops, apple tv, etc...) have any issues with the wifi.
I've tried resetting the routers, forgetting the wifi connection and setting it back up, rebooting the phone, smashing my head against the wall; nothing seems to have worked permanently.
Is it possible that this is a hardware issue and not a software issue? Has anyone else had similar results with multiple devices?

fix....?
this wifi drops are due to the router WIFI signal setting. it will drop it you are using a B/G Mixed signal/ B/G/N Mixed signal. i recommend setting it on 802.11 g. or, if all your Devices in the house have N use N since it has more bandwidth. i use G because of the PS3
Hope this helps resolve the issue for you guys, it sure did for me.

Thanks for the suggestion, I can attest that this wasn't a permanent solution for me. After switching to N mode only, the amount of times the issue occurred was reduced, but still happens at least once per day.
It's also a pain when I'm connected to networks where I have no control over the wireless settings (work, public networks, friends networks).

I have a linksys modem and router. Haven't had a single connection issue with this phone as I had with my EVO. As my wifi disconnects and reconnects right away. Lol. First time that has happened. Knocked on wood.

[Q] Is there any solution for WiFi not connecting to certain networks

My Nexus 10 works fine on most WiFi networks, but there are a few places where it fails. The N10 sees the network which has fine signal strength. It goes to the "Connecting" state, waits 30 seconds or so, and then drops back to "Saved".
I would think the network had non-functional DHCP, but I can connect with a Lenovo notebook instantly from the same place to the same network and AP.
The router that causes the problem is a Cisco 1200 series AP, operating vanilla 802.11g, with an open network, in the 2.4 GHz band.
I have tried all the Wi-Fi-related options in the N10, and removed and recreated the connection. I have found nothing that helps.
Has anyone that has seen this issue found a solution?

Seen this a million times, and it's one of my lingering dislikes about Android (although to be fair, I've seen the analogue -- much less -- on my iPad as well). Toggling the Wi-Fi state on and off like mad (or Airplane Mode) usually does the trick for me...eventually. Have you tried rebooting the router (relatively sure you've have, sorry) or using an app like Wi-Fi Analyzer from the Play Store to see if there's any channel interference? Mobile devices don't always deal well with overlapping channel use.

I cannot reboot the router because I have the problem in a public place (an airport). I do not have the problem with my own router.
I do use a WiFi analyzer, and there is no interference issue. The AP is on a clear channel, and the signal is very strong.
So the only and best solution it to turn Wi-Fi on an off rapidly until it works? Really?????

Never said it wasn't stupid. It's possible that the airport is using a network hack to facilitate its captive portal (I assume it uses some kind of gateway?), and Android is really bad about network "misconfigurations."

[Q] G2 WiFi speeds N+AC

Does anyone notice there's a big bug with WiFi on the G2?
I have 2 WiFi ac routers, one at home and one at the Office, an Asus RT-ac66U and a Linksys ea6700. Both capable of 1750mbps max speeds.
Internet speeds are 120/6 and 200/20.
Scenario is exactly the same for both routers;
When fresh reboot the router, G2 connects at a speed of 433Mbps.
Speedtests show results of 119/6 at home and 190/20 at the office.
Great you would say!
But here goes. Once WiFi get disconnected and reconnected, speeds go down to ~40mbps. No matter what I do!
These are N speeds, not AC
When looking at connection settings it still shows a link of 433mbps
Tested dozens of times, on both routers, so it has to be an issue with the G2.
Anyone else noticed the same??
DAMN, should have been in Q&A, mods plz move

I'm not an expert on wi-fi, but have stumbled through setting up several routers around the house. But I do not have an ac router.
Is the home router in mixed mode? Ignoring a/b/c for a moment and focusing on g and n (and implying ac), I have two wireless routers in the house. One runs N only (but both 2.4 ghz and 5 ghz) and the other runs G only. Now, my N router is capable of running in mixed mode (to handle both N and G) BUT in mixed mode, my max speed when connected in N is lower than it would be if I ran in dedicated N mode.
Most of my devices now are at least N (2.4 or 5) but I have an older printer and wii that only do G. But as mentioned above, rather than run my best router in mixed mode, I run 2 separate routers, one in N only and one in G only.
Maybe something similar might help with your ac speeds?

Really appreciate your input!
But I already tried settings like AC only etc. Doesn't make any difference.
Once connected for the second time and up to the router no more AC speeds...

Is there a way to test LAN speeds on Android? I have the same Asus router but my wan speeds are so pitiful that I wouldn't be able to tell if the phone was dropping to N speeds. If I could test speeds to my desktop across the local network I might be able to test what you are experiencing.

Is there a way to check on the phone, which band it's connecting to? I haven't found anything.
I have the same router and my issue is on reconnect. I leave my wifi on all the time. When I get home, it connects automatically the moment I pull up to the house. The problem is, the speed is severely crippled. Range is awesome, speed is bad. I have to cycle the wifi and reconnect. Once done, no more problems.
One thing I should note, I was having the same issue occasionally on my Droid RAZR after getting the ASUS. Does anyone know if they use the same wifi hardware? Maybe it's an issue with the router itself?

Don't know about an app to test lan speeds unfortunately.
Think a google search would come up with lots of options.
@crashN2u
I leave my wifi on too all the time for now, it keeps it at full speed then.
There's no way to check which band you are connected to.
Router doesn't have an option to choose AC Only, only N +AC
And in the mean time I have tested it with 4 AC routers, Asus RT-AC66U, Netgear R6250, Linksys EA6700, D-Link 868L.
With all routers exactly the same conclusion. First time everything is great. Excellent speeds. If you never turn off WiFi it remains at high speed.
But once you turn off WiFi on the Phone and turn it back on it immediately drops to ~36-40mbps max (N Speeds).
This remains until I rebooted each router and after that full speeds again.
It must be something in drivers LG used.
There's the solution to for, I'm sure of it by now.

Well, I can see I won't be much help -- especially since the same result on 4 routers!
I am not sure if the following app supports AC, but a very helpful and free app I use is called "Wifi Analyzer". I can't post links but that is the exact name (author = farproc).
It has many useful tools/functions that you may find helpful, switchable between 2.4 and 5.0 ghz, channel scanner, etc.
Does your 2.4 ghz N and 5.0 ghz N/AC have different SSID's? From what I read, AC is 5 ghz only and N can be either 2.4 ghz or 5.0 ghz. I wonder if you are dropping from 5.0 AC to 2.4 N because the 2.4 N is being detected as "stronger signal" than the 5.0 AC at reconnect time?
I named my 2.4 ghz N SSID as "Blah" and 5.0 ghz N SSID as "Blah_5ghz" just so I know what frequency I'm on at a glance (using a widget that shows the SSID) but many routers by default will have both SSID's the same, making it less obvious what band you are connected to. I also use an app called "WIFI Prioritizer" (author Robert Botha), which will allow me to connect or re-connect in the SSID order I specify: i.e. when I get home I will connect to SSID "Blah" (2.4 ghz N because it has the longest range). Every 5 mins (you can specify), it checks to see if my SSID "Blah_5Ghz" is in range and will switch to it if it is (you can also set signal strength connect and disconnect thresholds).
Anyways, I probably can't help further but am following this thread with interest. Good luck!

My Phone is packed with tools like Wifi Analyser, InSISDer etc etc atm
I always separate 2.4 and 5ghz networks to be able to see exactly what's going on but thanks for the heads up :good:
From further investigation and thinking, and with your suggestion about stronger signals;
Thing is, AC routers are more or less all simultanious routers.
That combines 2.4 and 5ghz signals for higher transfer speeds.
I think in there lies the problem when drivers are not 100%.
In theory 2.4 signals are stronger then 5ghz signals and have wider range.
But in testing I made sure that I was in the same room and no more than 2 meters away from the router.
when testing it showed equal signal strength up to -20 so really strong signals.
Therefore I concluded that N on 2.4 whas equally strong as 5ghz and then again I isolated 5ghz SSID so that's not it unfortunately.

I promised to stay away but I can't resist!
Have you tried some of the more generic troubleshooting tips (on the home network), such as trying with no security or lesser security (WEP) to see if it still reconnects at the lower (N) speeds? I realize that usually that test is of course for a more basic issue than yours but maybe the G2 has trouble handling security overhead.
Some devices and routers just don't like each other (as many know), but 4 different routers...?! Gotta be the G2 side, as you've surmised. Wish I knew someone with an ac router so I could test myself. I'm debating on getting an ac router but you've got me spooked! (kidding/teasing)

Well haven't tried lower or no security.
When I have the chance (aka the wife is away and not *****ing about wifi not available ) I'll sure try that.
But I don't think that WEP will be an option because AC requires AES protection if I'm not mistaken.
But really do not be afraid to get yourself an AC router hehe.
No honestly, I've tested 4 routers with:
AC Capable:
HTC One. Goes all the way to max isp speeds. All the time, no issues
LG G2.
Not AC Capable.
IPhone 5. Max speed at 5ghz (constantly tested) is ~90-100mpbs.
HTC One X. Max speed at 5ghz (constantly tested) is ~70-90mpbs.
So even if your hardware maybe not be capable of AC speeds you still get excellent connections
Oh and for the record.
Here's my personal listing of the hardware I've tested. From best to well not so good.
1. Netgear R6250.
Excellent constant speeds. No drops whatsoever with around 6 devices connected. Excellent range!
2. Asus RT-AC66U
Shame Asus introduced a new wifi driver some time ago which doesn't perform that well. Constant speed drops.
They know about it but thusfar no solution.
When you get this one, stay on old firmware for now!
3. D-link 868L
Real looker this one. Can be put in plain sight in the room like a picture frame :silly:
Great constant speeds, but some drops here and there.
Excellent range.
4. Linksys EA6700
Linksys is sold to Belkin by Cisco.
Up to now I have never seen anything good coming from Belkin!
What a piece of crap.
With a really thin wall between router and phones coverage went down more dan half. Hell even when distance less than 2 meters away coverage was about -45.
Do not get this crap!

I wonder... the wireless N spec (not sure if also AC) calls for devices and routers to have a 'low power mode', which may or may not be enabled in routers and/or phones (e.g. GS3) by default. According to some article I read, newer routers may go into a power saving mode if it detects low traffic and supposedly ramp up when the traffic increases.
Possibly it doesn't ramp up fast enough when a new device connects and the device mistakes it for not having the highest speed (AC) capability. Might explain fast speeds after router bootup but not later. If there is any truth to that (no clue here), it might speed itself up either by testing with a larger file or seeing if the "2nd connect" condition changes while say, streaming videos from the PC to the Xbox or watching Netflix on the main TV. Certainly, either would be considered high traffic and if there is no change to the 2nd connect, well -- there goes that idea.
Is there a wifi power saving mode on the G2 like there is on the GS3? (i.e. dialing *#0011# to turn it off).

Good point!
Well, there is a setting in wifi, advanced to minimize use of wifi when screen is off. Sounds like a power save mode to me.
But, just tested it and that makes no difference.
With that setting deactivated on the G2 still at first boot AC speeds and when I switch off and on wifi I still get N speeds max.
And besides that, on the Asus router there's a setting called "Enable WMM APSD". Which stands for "Automatic Power Save Delivery".
I read up on that and the custom firmware guru RMerlin writes about that setting that especially Android devices could suffer from that setting.
So I disabled that a long time ago.
On other routers I couldn't find such setting.
But to iron that setting out I just tested it once more.
First with setting off. Still first connect AC speeds, after turn off/on back to N speed.
Then turned wifi off, enabled the setting and rebooted the router.
But this time to let the supposedly power save kick in I let my Phone idle for 15 minutes so that it surely was in deep sleep.
Then turned screen on, and again AC speeds when first connected.
After that turned wifi off, screen of for 15 minutes. Turned screen on again and once more N speed.
And link speed is always shown as 433mbps btw, which is correct.
There's just some bug in driver code by LG which doesn't work correctly.
I'm more and more convinced of that.
For now I just keep wifi on all the time so that I always get full speeds.
Batt is capable enough so no problem there

I found a tool to test local network speed. It uses two android devices for a p2p test or you can install a server program on your PC. I'll do some testing and see if I can reproduce what you are seeing. Here's the link: http://pzoleeblogen.wordpress.com/2013/08/12/local-network-speed-test-for-android/ and the market link: https://play.google.com/store/apps/details?id=com.pzolee.android.localwifispeedtester&hl=en
And to be sure I understand, you boot your phone with wifi on, AC speeds. Turn off wifi on phone and turn it back on, N speeds. Reboot phone with wifi on, back to AC speeds. Correct?

Here's the link: http://pzoleeblogen.wordpress.com/2013/08/12/local-network-speed-test-for-android/ and the market link: https://play.google.com/store/apps/details?id=com.pzolee.android.localwifispeedtester&hl=en
And to be sure I understand, you boot your phone with wifi on, AC speeds. Turn off wifi on phone and turn it back on, N speeds. Reboot phone with wifi on, back to AC speeds. Correct?

Thanks for the app!
Gonna test this for sure since I also have a HTC One lying around which is also AC capable
Not 100% corect.
I can do with phone what I want until wifi gets turned off.
Then a reboot of the router is required to get AC speed back.
No need to reboot the phone.
Quite busy atm so don't have enough time I would like to be testing

Between my wife on her laptop, my son on his Chromebook and my daughter streaming Netflix on our Roku, I hardly ever have a chance to reboot the router without someone complaining
Since I haven't rebooted my router in days, from what you are saying I shouldn't see anything above N speeds until I reboot the router. Do you actually have to turn off wifi on the phone to have it drop from AC to N or is it enough to leave the range of the wifi and then come back? And does if turning it off is required, do I have to be connected to the router at the time I turn phone wifi off?
I'll try testing this weekend.

Going out of range isn't a problem as long as you don't have an app or setting on in wifi, advanced to switch off wifi.
As long as wifi isn't turned off I can go everywhere, in&out of range, other routers connect but speeds remain AC, everywhere on every router.
I can reproduce everytime that when I turn off wifi on the phone and back on from then on I only get ~36-40mbps max.
It's like the phone thinks that's max capable speed altough wifi link speed is again shown as 433mbps.
If I have switched off wifi on the phone and back on, on all 4 AC routers I tested all needed a router reboot to gain full AC speeds again.
Oh and maybe a small tip, I always say to the misses at home that there's a small problem with connection so a quick reboot is required.
Up to now that still works

I just did a few tests from my phone to my pc with 100MB data sets. I got between 200 and 260 Mbit/s down both before and after toggling my phone's wifi off and on. Didn't seem to make a difference. I got about 6Mbit up.
So, I didn't seem to experience the problem you have. But try repeating what I've done with this local network app. Maybe you won't have the issue with it that you are seeing on your WAN connection.

Wow and do you really see real transfer rates of 25-30 MB/s to your G2?
I'm using a Qualcomm Atheros based AC-router and my G2 (running latest CM11) hardly goes over 10 Mbit ~ 1,5 MB/s. Weak I know. (Confirmed 433 Mbit link using a wifi app.)
Maybe I need a broadcom-router like yours to see some real AC-speeds.
Thanks for the reply. Take care

Wifi speed going down to 1mbps

Hi,
I have realized that my wifi connection drops down from more than 20 to only 1 Mbps with my lg g2. It happens with 2 routers and seems that if I reconnect the phone then I go back to more than 20 (and short later in goes down again). Any idea what can be?

No suggestions on this one? I tried the location services changes with no success. I would say it is some app causing issues, but no idea which one could be...

got exactly the same problem
switching wifi off an on solves the problem for 2 minutes or so. then it drops to 1mbps again. tried different routers.
I figured out that it only concerns internet traffic. LAN traffic remains at full speed.
WHO can help please? :cyclops:

hmmm. wonder if this is the same problem a lot nexus 5 owners have including me.. there's quite a big thread on it in n5 QA section
there's no fix but workaround solutions include running in 2g mode or turning off data when on WiFi and even making a script to do so automatically when entering WiFi areas.
http://forum.xda-developers.com/google-nexus-5/help/slow-wifi-n5-t2514501

thank you for that interesting link.
unfortunately the solution turning mobile data off didn't worked for me.
I also tried static IP instead of DHCP - no success.
one strange thing, as already mentioned: LAN traffic to my computer works perfectly with max speed. (copying files e.g.)
so, wifi works in principle. It's about internet traffic only.
but which kind of software/hardware is able to distinguish between internet- and local traffic?
