Question Why are my connection speeds so slow

I am very pleased with S2 but have a concern about WiFi download speeds
I just ran speedtest.net on four different devices within minutes of each other

PC - 5.65 Mbps download 0.57 upload
iPad - 5.29 Mbps download 0.68 upload
Galaxy 1.14 Mbps download 0.68 upload
iphone 5.14 Mbps download 0.62 upload

All tests were to the same server

The S2 consistently returns around 1Mbps at any time of day - the iPad and Galalxy should be comparable as they are sat right beside my wireless N router??

I checked and it is definitely connected to wifi with a full strength signal and I cant find any settings that would limit the download speed. Whilst it seems pretty fast most of the time it does take longer than it should to open movies particularly in hi definition.

That is slow gbswales when compared to the other devices.

Judging from your user name I'm guessing you are situated in Wales, so not a million miles away from me.

I just ran the speedtest.net and got...

9.06 Mbps download / 0.33 Mbps upload


Unfortunately I cannot think of any setting that may be throttling your speed.

Edit

Just a thought... what version of firmware are you running on your SGSII/

Default Wifi capped? please help

Hi all, ive look all around n cant seem to see a soultion for this. Im aware there are a lot of people having wifi issues, but ive not quite found ne one reportiong this one...

I got my S2 yeserday, all seems great. but i notice the wifi was going slow so i tried a speed test which gvies me about 1.3 Mbps every time i run the test (speedtest.net) it will get about the same results, it will not go over 1.3mbps. how ever if i restart the phone n run the same test it will give me the full 10mbps again (just like my iphone 3gs) this will work for a short whilie and then the same thing will happen again n it will seem to be capped to 1.3mbps again and will stay that way until i restart the phone or router. Clearing all running application and ram proccessos wont resolve it, it needs a reboot

Ive tried changing channels on my router n that doesnt seeem to help, but as soon as ive change it the phone will work ok again, not everytime i change the channel but most time, (this is even if i change it back to the same channel it was already on..) ive put my router on N only n G only etc but none make ne difference.

also i dont no if this is more coisidence but lets say for a example i restart the phone upstairs, i might be able to keep running the test at 10mbps for a while but as soon as go down stairs it will be capped again, this works both ways , same if i restart it downstairs n go upstairs.

sorry about my spelling n grammer...

Thanks for the help.

Default according to kies the latest version

Pda:kf3 / phone:ke7 / csg:kg2(o2u)

I just downloaded a programme called network info which shows my link speed as 54Mbps which is on the slow side for a wireless N router but should still give faster d/l speeds than I am getting

Unfortunately your issue may lie with the older firmware (KE7 (late May)) as this was not very good with WiFi. This was fixed in later versions.

It looks as though you are on O2's version of it as well which means that you are at their mercy for updates unless you decide to go down the root and ROM road.

Default problem appears resolved

I was in the process of changing from 02 pay and go to a vodaphone contract anyway. When I activated the vodaphone card today my speeds shot up from 1.1 to 5.00 Mbps - looks like O2 were somehow controlling the wifi speed!!! Possibly to make their over the air speeds look better than they really are!!

Exclamation Almost conclusive results!

These results are pretty conclusive - the pink shaded ones are with the O2 pay and go sim card and the green shaded ones are with Vodaphone sim only contract sim. In the green period the iphone results more or less matched but int he pink period the iphone results were much higer around 4-6 Mbps

It is my guess that O2 have somehow crippled wifi - cynically I might conclude that it would make their over the air internet seem faster than it really is. I cant think of any other logical explanation.

O2 know that I need to use both cards (they unlocked the phone for me) and I intend tackling them about this

Thanks for all your comments - I am a happy bunny now

(Though not with Samsung phone support who tried to convince me that it was simply design differences and that 1 Mbps was a "very good speed" their operators most classic comment was however " well it is not really an internet device!!"

Strange... I cannot think of any way that your sim card could control your WiFi speed.

It looks to me as if the original O2 settings pass it through some random proxy address - when I put the vodaphone card I received a text change of settings, since this only my IP address appears in the IP address column of the speedtest result (have partially hidden for obvious reasons)

192.16N.NN.3

10.74.5N.156, 192.16N.NN.15
I checked all of the first ip addresses in the O2 settings and they are all "private" and cannot be looked up to see who owns them!

Blow me down!

That might be the answer to other posters who are complaining of low WiFi connection speeds.

There's something wrong somewhere, that's for sure. There's no way that APN settings (for mobile internet) should influence wireless connections through a broadband router. O2 must be futzing around with ARP tables or something similar at the IP layer..... bad O2!

That suggests that it's a routing issue introduced by O2, as that Class A subnet is only routable from within their network. I don't suppose your device is rooted, is it? If so busybox has diagnostic tools that would reveal more....

Yes this was on my wifi and at the same time as other devices adjacent to it consistently posted faster speeeds - I am on a business level contract with a smaller ISP but limited by not having any LLU suppliers locally - however I consistently get between 4-6 Mbs depending on time of day

Pretty much what I had deduced still as I am now with Vodaphone and getting faster speeds its not my problem now but thought others with the problem on 02 might like to take it up. Was a time when 02 were my isp as well but the company seem to have gone down the pan through mass signups like others before them

I've noticed the same problem with my Galaxy S2. I tried running a speed test with Sim Card removed, and the results shot up. While my sim card was in it seemed to be capped at around 1Mb/sec, and without it was around 5 or 6 (which is a typical result for me). I'm with Talkmobile, just wondering if you were with the same?

I wouldn't be so quick to point the finger just at 02, as I'm with Talkmobile, and I'm having exactly the same problem as you described. I tried my phone with a GiffGaff sim in it and the wifi was up to usual speed, but as soon as I put my own Sim in it seems to be capped at 1meg a second.... No sim card in and it also works at full speed! Any one any ideas?

If you run a few tests using the speedtest.net app some using your carrier and some without the sim and then view the historical data one of the columns shows you the IP addresses. I havent tried without a sim but with the vodaphone card only my IP range is shown so it's clearly connecting direct to my wifi however with 02 card in a second untrackable IP address is there which suggests to me that it is somehow forcing it through some kind of proxy server. Would be interested to know if yours does this.

I can think of a few reasons why they might want to do this
  • tracking for business advertising services
  • monitoring activity for legal purposes
  • slowing down your wifi to make over the air seem quicker than it is
The last one may sound far fetched but for a brief time a couple of years ago I had 02 as my ISP and during the 30 day trial period they offered at that time I had the fastest speeds I have ever had with anyone an almost consistent 7Mbs on an up to 8Mbs connection. about a week later speeds dropped to an average of 1.5 Mbps - after a lot of time wasted on calls and testing router etc - I threatened to sue them if they did not let me out of the 18 month contract - which they eventually did and refunded my last months subscription.

For phones I think it may be different between their contract phones and pay and go - my partner has a monthly contract for the iphone which has good speeds (as mine did).

I've tested my o2 sim on both home & work wifi and dont have any issues.

Home - Down 2.18mbps Up 0.38mbps. This is on a 'up to 6mbps' service, which only gets about 2-3mbps in real terms.

Work - Down 9.07mbps Up 0.93mbps. This is on a 'up to 20mbps' service, which gets about 17-19mbps in real terms

would the sudden loss of speed and change in Ip not suggest that the phone has lost connection to the router and is instead downloading via H or 3g?

Tested with 3UK PAYG: 6.20/0.99Mbps, almost identical to results with the Orange SIM in place.

@gezmond: the Speedtest app indicates the connection in use.

@gbswales: take a look at the APN settings with your O2 SIM in place. Is there a proxy entry anywhere?

My problem is definitely sim card related as I've just put my phone in flight mode and switched the wifi on and the speed is around 7 Mb/s, as soon as I go back to normal wifi drops to 1.... Just to note that at home I only get 2g. Worst thing with this problem is knowing who's to blame Samsung or networks.

New theory... Just had a look at some speedtest results from last week when I was away in a hotel. At that time I was achieving 2 mb sec on wifi however I was getting much more than that on H+. Co, uld out be that being in an area where only 2g is available caps your wifi speed, phone recognises it's only on gprs network and so caps it's speed... Just a thought, but maybe would explain previous o2 problem.

That's a neat trick.... wifi should be disabled when in Flight Mode.

You're on Talkmobile, yes? If so then the puzzle just became even trickier.... they're a VMNO hosted by Vodafone, who weren't affecting the OP. Time for another I think.

By default wifi is disabled in flight mode but you can switch it back on if you slide down from top, and yes I am on talkmobile.

Is there anywhere at your house where you only pick up 2g, if so you could test my theory!

Friz I doubt your right as I have data turned off and manage to get the same sort of speeds with it on, off or in my old house which was able to get 3G (new house can only get 2G)

I think that there might be something in my theory as I've been up to my parents and tried the wifi there. I get edge at their house and my speed seems to be capped to 1.7 m/sec rather than the 1 at mine.

Default Galaxy s 2 wifi

I have the galaxy s 2 i9100 and android 2.3.5 for 4 months.

From the first moment i sensed that the wifi speeds are low.

comapring to pc (lan) or laptop (wifi) there is 4 Mbps difference.

12Mbs pc/laptop camparing to 8Mbps on galaxy s 2 .

But the upload speed is the same (1000Kbps)

That is exactly as your results "gbswales"

Also , this result has nothing to do with my internet home carrier.

I also did the following test . I turned the home internet off, and operated the galaxy s 2 on router mode. (with no 3g or 4g internet) this way there is only the wifi network that created by the galaxy s 2 . When downloading a file with kies to the phone , speed is low . about 2.5 MBps .
This test does not indicate anything about the wifi problem .... i am comparing with you people to confirm.

According to all these results I would gamble on a driver problem.
I hope it is fixed in android 4 .

I also upgraded from android 2.3.3 to 2.3.5 and installed an original samsung localized rom (at samsung labs) . and the issue remains .
Also, there is nothing wrong with the wifi bars ,And i am 1 meter from the wifi router.

I have not yet figured out how to contact samsung headquarters about this .

I dont understand "gbswales" how can an internet supplier (especially the cable based) can

interfere with the speed of one device and not the other one ?

Also, if you insist , i have another carrier sim . When i switched to it the problem remains .
This is not logical because the 3g/4g connection is off in the phone for both carriers .
One carrier is not a sim card for my country . It is only when i am abroad .

I turned the cellular reception off (fight mode and then wifi on ) : the issue remains .

All that has been said about Wifi reception , Nothing has been said about cellular reception (bars) Which are very low . As you know : when bars are low : the phone increase its cellular radio in attempt to get more bars .
There is a small antenna connector above the sd card slot. I am trying to get a small connector + wire for this connector ... anyone have any ideas ?
I have seen a yotube video when someone puts a pin in that hole and the cellular bars go up. .. i cant find it now .

This may be related. We have 4 different Android phones, 2 different carriers, and a wifi only tablet; Linksys wireless N router (WRT160N). We were suffering from slow download speeds across the Android devices, but no problems on laptops.

In the router settings: Applications & Gaming>QoS>check "disable" WMM Support. Download speeds according to Speedtest.net went from 0.5 Mbps to over 20 Mbps.

My router doesnt has no wmm settings or qos.

I didnt talked to samsung in my country about the problem yet.

By the way ... when sharing the galaxy s 2 wifi connection the receiving computer computer sees a "G" network . Isnt it suppose to be "N" ?
(Before even trying the "qos" thing on the network adapter icon on the computer)

Yeah, just checked mine and I am getting nearly as much on the phone as I am with the computer. I get 45 Mbps with my laptop.

"Baldilocks" , Which android version are you using , i do not recognize your wifi icon with arrows ?

My Wifi speed can be very high but it is always ~ 2Mb below what other computers around it are

getting.


I connected the galaxy s 2 as a cellular modem ( sharing internet connection )

though the usb to the computer for the first time ...

At least here the results are o.k . ...

The adapter speed is 425.9Mbs (picture attached)

This is the average speed of a usb 2 connection.

My cellular 3g network is very slow , so i wont be checking the speed with it to

the computer. ( i didnt get internet wifi to computer through usb )


Note : i corrected my first post : The speed is 2.5 MB/s not Mb/s . Sorry for that mistake...

"I also did the following test . I turned the home internet off, and operated the galaxy s 2 on router mode. (with no 3g or 4g internet) this way there is only the wifi network that created by the galaxy s 2 . When downloading a file with kies to the phone , speed is low . about 2.5 MB/s ."

"Baldilocks" , what is your internet connection speed ?

Anyway, your results looks the same percentage drop in speed : ~ 16% .

I have a 40Mbps Down/3Mbps Up Connection.

My computer averages anywhere from 38-46 down. The phone usually stays right around 38-39.

When dealing with very high speeds it doesnt matter so much as in low speeds
( like "gbswales" who posted the first post)
But i have no comparison about transfer speeds from computer to phone ( with kies file explorer through pc browser ( over wifi) for example)
I get 2.5MB/s .
i have a 54Mb level one wbr-3406-tx router .
That is 6.75MB/s , big difference from 2.5 MB/s

Wink Galaxy S2 & S1 Performance

I was having performance trouble on the home network even though both the Galaxy S2 and S1 performance was fine on other networks.
Speeds were under 200Kbps even though the Macbook Air could get speeds of over 6000 Kbps. This is with Comcast high speed and Cisco (Linksys E4200), a pretty fast router and a Motorola SB6141 also the latest. When I first connected these, we had blazing performance on the phones.

The first step I took was to use the Wifi Analyzer from the app store. It makes a nice graph of wifi signal levels in the area. My Wi-fi was competing heavily with others on channel 1. I found a hole in the spectrum of users and changed settings on the router from automatic to channel 8.

Step two was to 'forget' my wireless on the phone, and reattach to it using the phone wireless settings menu. This got my phones going like the blazes again. It is hard to say what changed as part of this configuration. One refinement might be to power down your phone and restart it from scratch before taking these steps.

One of my favorite sites for download performance is performance.toast.net
