WiFi Network Speed - Microsoft Surface

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.

Thanks for answering but did you even read my post? ? Anyway, Laptop to Desktop PC is ~5 times faster over the same WiFi network.

Thanks, we get the same. If I copy a file from my sd card to internal memory I get 19MB/s so I don't think it's about disk speed.

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] 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?

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

Wireless LAN PC-to-phone transfer speed

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?

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.

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] 3G Dongle

Hello there,
I was wondering if there is a way to use a 3G dongle with my Asus in order to have internet access when i don't have a wifi connection.
If i can't use a dongle could you please offer me a solution to a matter extremely important to me and many others as internet on the go.
Thank you in advance,
Perhaps you should consider tethering to a phone via WiFi or Bluetooth for internet access.
I use a G1 Dream for tethering via Bluetooth. Bluetooth uses less power than WiFi.
Assuming you have a smartphone, tethering is the way to go. You could mcguiver up something with the sub dongle a rocket stick (sub cell modem) but tethering is way easier and you are already paying for that data plan. Did exactly that tonight and was getting over 18 Mbps down.

I use a 3G Huawei E586 mifi device which works perfectly.
Thank you all for your kind replies, the easiest method of them all seems to be the tethering.
I have a smart phone, and i will try tonight the aforementioned method to see if it is working.
Do i have to enable something else besides bluetooth on my phone before i make a connection with my tablet?
Something that i didn't understand is the way that you proposed me with the 3G dongle.
Do i have to buy my own 3G dongle of this particular brand ( Huwei ) in order to make it work
with the usb slot on my keyboard?
Again thank you all, you have been very helpful and you saved me from a lot of trouble,
thumbs up for your help to this thread:good:

Hi
I'm not sure about the other brands. But Huwei works fine. If you want to tether from your smart phone better use the wifi tethering in stead of bluetooth.
Good luck

If your smart phone will not "tether" easily, you can try the Vodafone Mobile Wi-Fi R205. It will provide Wifi access to the internet to any device you might have.
I'm too new to the game to be allowed to post a link. Got to vodaphone DOT gr. Click eshop, then usb sticks.
Other mobile services here in Greece may have something similar.
It's simple as can be.

Thank you all again for your replies,
I have just tested and it works like a charm the tethering method through my mobile, but as i have read in a couple of posts up
i was suggested to use wifi tethering in stead of bluetooth.Why is that? What are the pros and cons of one method over the other?
My kind regards,
Using WiFi or Bluetooth each have their pros and cons.
Security - Bluetooth has encryption built in. Vulnerabilities have been identified in Bluetooth's encryption, but even with today's hardware it would take a few hours for a machine to crunch the numbers required to crack a Bluetooth session. With WiFi tethering, assuming you are using WPA or WPA2 on the connection, the encryption would be stronger and thus more secure. WEP encryption would not be any more secure than Bluetooth but would still discourage casual snooping. I'm not sure if something like Cyanogenmod's built-in tethering offers WPA, but I know applications like FoxFi do. Advantage on security - WiFi
Speed - If you've got a 3.5g or 4g connection, your tethering connection could be a speed bottleneck. Bluetooth is really only capable of around 2 Mbps (that's megaBITs per second, not bytes). That's still faster than a T1 wired connection or the same speed as a euro E1. I'd consider that plenty fast for one machine browsing but if you want to support a number of machines through tethering you might notice a slowdown. WiFi gives you 11Mbps and maybe up to 54Mbps. Advantage on speed - WiFi
Distance - Bluetooth is only useful to a maximum of around 10 meters. WiFi could go as far as 100 meters. Both protocols are susceptible to interference from just about any nearby electronic device and neither does a good job of going through walls or other obstructions. Advantage on distance - WiFi
Power Consumption - In some use cases, Bluetooth's speed and distance limitations are drawbacks. But those two things combined add up to Bluetooth using much less energy to operate than WiFi. On two mobile devices, longer battery life could be important. During WiFi tethering, batteries tend to discharge so quickly that they release more heat than normal and many tethering apps monitor the battery's temperature so it doesn't cook. Repeated overheating can shorten battery life. Advantage on battery life - Bluetooth
Bluetooth tethering is of course useless for devices that don't have Bluetooth. I'd love to be able to tether my Nook Touch, but my battered old G1 has a broken WiFi board and the Nook only uses WiFi. Other than that, I haven't found any disadvantages to using Bluetooth for tethering.
Hope this clears things up some.
Bt: saves battery, slower speed and can connect only one device.
Wifi: battery consumption, higher speed and can connect up to 5 devices.
I hope that helps

Yep, it has ac wifi. Theoretically good for gigabit speeds, but I think the highest hit so far is 800mb/sec. The main advantage I'm finding is that you can connect to the 5ghz wireless spectrum (vs the old 2.4ghz).
