Wireless LAN PC-to-phone transfer speed - General Questions and Answers

Is it normal for me to experience a cap at ca. 2.5mb/s while transfering files from my pc to the phone through a wireless lan (802n, 2.4ghz router)? The transfer speed between 2 computers is close to 11mb/s
My phone is a Samsung Galaxy S2 I9100.

What app are you using? Could it be a free app, with an incentive to upgrade to pro?

Are you transferring the data onto the SD-Card? If do, what speed rating does your card have?

Oh yeah, and how is the speed from phone to pc?

Tried with WellFTP Server and MyPhoneExplorer. Same speed and both free apps with no pro version available.

Seems to be about the same or slightly slower (ES File Explorer doesn't show me transfer speed or time elapsed)

How about running a speedtest over your wifi network (with nothing else using bandwidth, obviously)?

how do I do that? Doesn't speedtest only work for internet connections?

Well, yeah. What I meant was to do 2 speedtests: one on computer, one on phone. Then compare the results. If they're the same, then there's nothing wrong this side of your router. I suspect the results will be significantly different.

What speed do you get if you connect your phone to the PC via USB and try writing files? I suspect it is simply down to the write-speed of your internal storage.

Ofcourse. It's about 6-7 Mb/s. Because of SDCard write speed.

both report the same speed.

And what speed is that (approximately)?

That of my internet service: 6mbps downstream / 768kbps upstream.

So, to summarize, you're getting:
6Mbps from your phone to internet
6Mbps from your computer to internet
2.5Mbps from your PC to phone
all while using the same 802n, 2.4ghz router, right?

Exactly.
I should try my Laptop-to-PC just to see the speed also, because I realized that when I said that the speed to the other pc was 10mb/s, I didn't remember it is actually a wired network, lol. But still, is 2mb/s what I am supposed to get with n-wifi on a 2.4ghz router?

[Q] HTC Inspire 4g Large file download issue

I noticed when downloading large files of any kind on my inspire or on my laptop (W-Vista) it always cuts off after 10 percent or somewhere near that, I was wondering why does this happen? Is it my phone, or a setting that needs to be changed, or my data speed?
Note
-Inspire 4g is rooted (coredroid)
-Files size are somewhere around 200mb - more
-Downloading speed usaully around 2.30 or higher

Forget about the phone for a second. Am I reading your post correctly - you have this problem when downloading a file to your laptop?
I assume the laptop is tethered to the phone while downloading.
Yes, while my laptop is using the wifi hotspot of my inspire.

[Q] internet pass through not as fast as pc

is it normal for the pc internet to be around 24mbps and the phone to be around 3 mbps under internet pass through?
also under Control Panel\All Control Panel Items\Network and Sharing Center
it lists my normal pc connection which has internet access and then it lists "unidentified network" with "no internet access" is that normal?
i tried asking this in another internet passthrough question but i think it was overlooked. i also tried looking for detailed walkthroughs on line but i was unsuccessful. any help will be appreciated. thanks in advance
I just checked it out with 2 different phones and my desktop (which is wired to modem) and my laptop (wireless). And got about the same numbers so I would say ... Yes that is the norm.
why so low though? shouldn't it be close to the pc internet since its using the pc internet? some times it doesn't even get to 3mbps and stays around 0.60
why is the internet passthrough so slow compared to pc internet?

Probably a hardware limitation.

Also its even slower when I enable wifi from a internet pass through phone
has anyone noticed when u use the pass through feature u cant go to the market and download anything? i noticed it wouldnt load the market and wouldnt let me download nothing so i thought this feature was pointless then
also i dont have the issues with slow download speed with the internet pass-through thing. my internet is 15mbps and my phone gets 9mbps using pass-through

It's not slow? What is making you say that? If you are referring to USB transfer speeds that is not the sdcards fault.

nobody can because we don't know what you're talking about. the nexus s accesses the file system at a very fast rate.
he probably means that he has slow transfer rates form pc to internal sd card, if that so, then maybe this help him.
Mine is slow to my files will only transfer at 1.4-1.9 m and my wifes same phone copys at 8-9m/s any way to fix this

Yes, don't bring up old topics. And use the search function.
But otherwise there's many ways. Transfer from within CWM. Use MTP. Or check my signature, even!

WiFi Network Speed

Hello, I have a simple question.
My Surface connects to the router (ASUS RT-N66U) with link speed 270Mbps. When I copy files between the Surface and my Win8 desktop I get 4-5MB/s (~40mbps) in transfer speed. Is that all the Surface can manage? My laptop gets 25+MB/s (450Mbps link speed).
Can someone try and post results here?

Upload speed?
I'm on my home network coping a file from my PC to my Surface over wifi. I am not doing it over the internet.
Why are you assuming the Surface or the network is the bottleneck? Try the transfer between different devices (Surface and laptop, Surface and desktop, laptop and desktop, etc. Also try downloading a file over the Internet if your connection is fast enough that it won't bottleneck that (some people have such connections...). Try over different WiFi connections if possible.
The first step when you find a problem is to isolate it.

I can push/pull 5-6MB/sec over 802.11n (2.4 or 5ghz) which seems to be the disk speed limit when using a class 10 SD card.

Ehhh... sorry i thought the RT versions shared a lot more. I have an ASUS Vivo Rt and if you open the Network and Sharing Center, click on Change Adapter Settings, right click on you wifi adapter (my case Broadcom 802.11bgn SDIO) select Properties and then configure.
It's strange that they decided to add something else to the soc.

Yep, tested mine. Read/Write doesn't matter, maxes out at ~5MB/sec - even on a "270 mbit" 802.11n 5ghz link with 5 bars signal.
So I guess that's as fast as the arm cpu can push bits.

No they don't - their speedtest shows 2/1.7MB second, which is 20/17Mbit. You and I and most people are seeing between 40-50Mbit/sec transfer speeds on your local network, which is not horrible for 802.11 wifi
This is a pretty good description of maximum throughput on 802.11
http://www.buffalo-technology.com/en/wireless-802-11-technologies.html
We're getting close to max speed for 802.11a or g at 5MB/sec (~50Mbit) - it's possible to get better performance out of 802.11n but you've GOT to use wide channel mode (in 2.4ghz) or 5ghz mode with multiple antennas (2T2R,or better mimo - http://en.wikipedia.org/wiki/MIMO) to essentially double/triple up your channels. Apparently (and not shocking at all) the surface might only have 1T1R
For the record: a Byte is eight bits. 2/1.7 MBps is merely 16/13.6 Mbps.

[Q] Backwards WiFi tether

Does anyone know of a way that I can use an old Droid X as a reverse WiFi hotspot? What I want to do is use the existing WiFi in my house and connect to a device that does not have a WiFi card in it. Is there a way to connect my old phone to my wireless network, then share that connection through the USB cord? Thanks

Yes, It's called "USB" tether. It is built into ICS and Jellybean. Also the app "PDA 3.5" works very well for this if you are on GB or below.
edit:
Just to further explain, you just connect your droid X to your WiFi network, then hook it up to the computer you want internet on with USB, then go to settings > Wirelss and networks > more > tethering a portable hotspot, and select the USB option.
If that does not work then use PDA 3.5 (free market app, works well, gives you full instructions)

Thanks I'll give this a try when I get home. I figured the tether would only work on a data connection. I know in the past when I've tried turning tethering on then it automatically would turn off my wifi.
As far as I knew to get PDAnet to work you had to install on the computer as well. Does PDA 3.5 work the same way? If so I won't be able to do that as I have no way of installing it on the device I am trying to connect to the internet.
