I have a windows surface pro 3 from work, it is on a domain and all firewall and security settings are locked up but otherwise I have full admin rights.

I upgraded windows 8.1 to windows 10 Novemberish and all went fine, however I have noticed over the past few weeks when on my home network browsing is slow as anything, I haven't had the chance to check it on my work network since mid December (I'm a teacher going back to work in a couple of weeks).  I think I have narrowed the browsing issue to the down to the upload.

Going through speedtest download 56.25 Mbps upload times out, dropbox uploads at 2-3 kbps onedrive simply fails.

I would put this down to wifi as my desktop gets this 



however my android phone gets similar results to my desktop 32 down 26 up

Surface pro 3 is running windows 10 latest updates wifi right next to the router
The router is a fitzbox
ISP 2 degrees VDSL

I would take it to IT but unless I tell them what needs to be fixed they will go through the "have you tried restarting the computer/router/internet ... then they will blame it on my internet configuration.

What tests/settings can I check to narrow down the issue?

Cheers

No Lan port.
Might have to in to school to see if I can grab an adaptor.
Do the display port to Lan that the macs use work on a surface?

No. Those are thunderbolt I would guess. You need USB

Ah then getting a usb lan adapter might take some time.

Are there any settings I could be looking at that would interfere with the upload speed.  There are a number of other devices on the network both windows and android however the pro 3 is the only one on a domain.

My wife has a pro 2 and I have an rt that both work fine, the au pair has a toshiba that she has no issues with.  There are two desktops and 4 android phones that are also without issue.

It occurred to me that I could tether my phone and test it that way.

SP 3  usb tethered through an S4 on 2 degrees.


SP 3 hotspotted through an S4 on 2 degrees.


SP 3  wifi on home network (fitzbox) 2.4 GHz Unlimited vdsl through snap

Download 48.82 Upload hovers around 0.07-0.02 ping 6ms  test hasn't finished after 10 minutes and is sitting on 0.00


SP 3 wifi on home network (fitzbox) 5 GHz

Download 60.68 Mbps upload got up to 0.14 then trailed off to 0.0 and has been sitting on 0 for almost 10 minutes

S4 on wifi on home network (fitzbox) 2.4 GHz Unlimited vdsl through snap



Desktop i5 lan connection



So the issue appears to be a combination of that laptop on the home network

lxsw20: Not using DirectAccess or something are you?


Not as far as i know, I need to remote desktop in to gain access to the school drives.

Funnily enough when I remote desktop in and there is no lag, uploading a very small word document is almost instantaneous, however trying to upload a 5mb file locks it up

I'm having similar problems - SP3, Fritzbox (on a Spark UFB 30/10 connection), and Onedrive uploads fail (supposedly - they might just be taking forever, I wasn't patient enough to give a 1MB file more than a few minutes).  It seems to be okay for browsing (i.e. mostly downloading) on either the 5GHZ or 2.4GHZ channels, but it refuses to upload (but will upload when tethered to my iPhone).  My Windows 10 PC on wifi works fine to upload, suggesting it's the SP3 that's at fault.  I was preparing for a reinstall of Windows to see if that fixed it, but will give the link above a go when I get home tonight and see if that fixes it.

I have a similar issue with my SP3, it does seem to be a problem with the in-built wifi as a USB wifi dongle worked fine for me.

and we have a winner




From above link

 

1.Press Windows button. Search for regedit. Open it

 

2. Navigate to the following path:

 

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\mrvlpcie8897

 

3. Find the item labeled “TXAMSDU”. Double tap and modify the value from 1 to 0

 

4. Restart the machine

 

Cause:

 

We have a known issue with .41 that results in low throughput with specific access points. The issue is specific to MAC layer aggregation (AMSDU over AMPDU) and only impacts a small subset of access points. We are working on a fix for an upcoming update. Until the fix is available, please update the registry key setting to work around this issue

Now what did this actually do to the machine?
