I have a pc with the same NIC, AC8260 and have the slow trouble with my office environment(Cisco Aironet 802.11ac AP), but don't have the trouble with wifi in my home(Linksys 802.11ac AP). > netsh interface ipv4 set subinterface "Wireless Network Connection" mtu=1400 store=persistent Please replace "Wireless Network Connection" with your WiFi interface name. decrease the size of MTU of the wifi interface. > netsh interface ipv4 show subinterfacesĢ. I am following this thread.ĭecreasing your MTU for WiFi interface to 1400 may solve the issue. At home is really fast but in university is incredibly slow. I am having the same problem after creators update. I will let you know if I discover something new. I discovered that if I establish a VPN connection I can work smoothly even in our corporate wifi.ĭo you have to possibility to test a vpn connection through your wifi? The odd thing is it happens at our corporate site,
I am experiencing a similar behavior after creators update,Īlso tried driver uninstallation, update, bios update, netsh winsock reset, uninstall vpn client, many different things If you have no noticeableĭifference with Ethernet cable comparisons then that narrows down the problem. If that was not done in the right sequence there was a noticeable difference in internet speed.
One of my old internet providers had software updates and software pushes that required a proper sequence for rebooting. For example ping Then you can also run round trip commands RT.
So I have better performance now, but not as good as it was.įor the wifi you can check your speed with ping command from admin command prompt.
Now, Jumbo Frames don't apply to WiFi, only to 1Gbit Ethernet adapters, so this is even more puzzling! Of the WRITE speed (I would expect READ to be higher). Now I get a file copy READ speed of 1.5Mbs - a lot better, but only 1/2 the speed As an experiment I looked into what I could change on the NAS endpoint & found that Jumbo Frames were turned on.
So this discounts (a) a problem with the WiFi router, (b) the endpoint I am reading from Another computer running same Win10, using same WiFi connection point & reading from the same Endpoint works as expected.READ via other WiFi connection points to the same endpoint as (1) performs as expected.Very slow READ (file copy) via 1 WiFi connection point.Please refer to the Launch Date for market availability.As I mentioned above, I have already done the adapter delete/re-install with latest driver.įrom performing other tests this is what I seem to have: Functionality, performance, and other benefits of this feature may vary depending on system configuration.
