Hello, I'm new here but I've read a few threads about Win10 on here via Google before I joined up.
Basic problem: my wifi download speed has turned awful and I think it was about the time of Windows 10 Anniversary Edition.
I've been using (for some time) a TP Link 300Mbps Wireless N PCI Express card (TL-WN881ND). The PC it is on isn't that new but it functions fine and has been just fine for wifi until very recently.
I've got 9.99Mbps up and 40Mbps down on my broadband in theory (as reported in the router dashboard). If my wife runs speedtest.net on her laptop she clocks 35Mbps easy down. If I run it on my iPhone or iPad I get similar. If I go to my desktop PC I'll get much slower responses - from 0.1Mbps to maybe 15Mbps.
Indeed I can be at a "full" signal (all bars lit up) one moment and the network doesn't even show on the list another moment - and yet I can still see and use it on my iPhone/iPad or my laptop PC sat in front of my desktop PC. Indeed it has disconnected a few times whilst I've been typing this out - as you can imagine that gets very frustrating trying to do very much.
Looking online I've found suggestions (obviously) to update the drivers. Well a TP-Link TL-WN881ND doesn't have an updated Win10 64 bit driver but Win10 chooses a Qualcomm Atheros AR9287 Wireless Network Adapter (and forum searches show this is the right driver for that chipset wifi card).
I've also found that suggestions are to run NETSH INT TCP SET GLOBAL AUTOTUNINGLEVEL=DISABLED rather than NORMAL. Trying that and re-booting/trying gives no difference so I've reset to NORMAL.
Going to my router dashboard I can interestingly see that the devices that are attached show a port speed of 65Mbs for all devices apart from my PC and my laptop. The laptop shows 104Mbs.
The PC shows a port speed of 5.5Mbs!
(And the laptop is pretty much sat on top of the tower of the main PC so I don't think it is signal!)
I've gone into what this dashboard calls the client monitor and the rate bounces up and down but download speed is pretty much always slower than upload speed. The most I've seen the port speed is 19.5Mbs.
This suggests to me that it isn't the router that is gating the speed but there is a shortcoming in the network adapter/driver compatibility with Win10 (it says it is compatible but clearly not as compatibile as something that's come out since Win10).
I have tried uninstalling the Qualcom driver and installing the TP-Link driver instead (with re-boots, naturally). That didn't make any difference. I've now reverted to the Qualcom driver.
I know the signal to the router is good - not only does it show well on other devices and in the router dashboard but we just had the cable from the incoming phone-line replaced recently.
Does anyone have any ideas for anything else I can try? I'm getting to the point where asking for suggestions for a replacement card is the next obvious thing to try.
