intel r dual band wireless ac 3165 showing as not connected

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,

remote desktop connections are difficult to establish and slow in displaying.

opening of specific websites is slow (for example also ).

outlook does not complete send/receive,.

skype for busines is not loading completely,.

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.

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:
