I have two computers one is microsoft surface 2 and other is asus laptop. Recently (about a month ago) my wife and I both noticed our internet was slow (less than 10mbps) on both computers. I started running speedtest.net tests on all our home devices (computers, phones, xbox, desktop, etc). The phones achieve the internet speed that I am paying for (70 mpbs or greater). The desktop that is hardwired to the laptop also achieves high speeds. The xbox (also hardwired) also works well and I have not experienced any gaming issues. Originally I was using a TPLINK WDR3600 router. I noticed it was behaving quirky on the 2.4GHZ and signal strength was iffy in corner of hte houses, basically I thought the router was dying before this even started happening. So I recently upgraded to ASUS AC1900 router. Supposed to be top of line correct? I get good signal strenth all throughout the house and my phones, desktop computer and xbox are all still humming along.

So at this point, I don't think its the router based on some of my devices being able to achieve the speeds.Seems to be something isolated to the computers (both running windows 10). Some of my troubleshooting I have performed right next to the router but still get slow speed.

I first started thinking it was the drivers, I have updated, disabled, uninstalled, reinstalled drivers for both. No improvement.

I then found in these forums someones saying AMD Quick stream was running in the background and once they disabled that they were able to achieve higher speeds. I don't have quick stream on either computer but got me thinking it was some service or program impinging on internet traffic. I first though it might be the citrix receiver application my wife has to use for her work. I disabled that and at first it seemed like that was the culrprit. After restarting the surface after disabling citrix I was able to get 70 mbps, but shortly after, it returned to slow speeds. I then went after malwarebytes and disable its realtime protection, again got good results initially but then went back to usual slow speed.

I'm down to thinking its the wireless card hardware but if thats the case how would this problem start exactly around the same time. Also the hardware is different in each computer. The surface as the Marvell network device. And asus has inttel centrio wireless n-2230.

One last note, on the wireless status window, the speed on both devices is shown at 144 mbps (asus laptop) and 162 mbps (on the surface). So if thats the connection speed to the router, what is preventing realtime traffic to 10mbps?

The surface 2 with marvel hardware can run both 2.4 and 5 ghz, b/g/n protocals. I have it on the 5 Ghz.

Any help or guidance is appreciated.

I resorted to the Reset This PC option on Windows 10. It worked on both computers. Still don't know what application/process/service was impinging the traffic.

I did the reset pc clearing apps and settings but not personal files option.
