I have Thinkpad T460s, Windows 10, WiFi adapter is Intel AC 8260, driver is 19.50.1 - latest.
Router is Asus RT-AC88U, internet link 150Mbps.
From few days I'm experiencing extremely slow connection/transfer speeds, like 100Kbs. I'm connected to 5GHz band. I tried resetting TCP/IP stack, reinstalling the driver, rebooting the router, none of that helped. I don't have antivirus or external firewall installed.An Ipad which is sitting next to my laptop is hitting easily 90-100Mbps.
However when I connected the laptop to my work wifi, it appers to work normally, so logically it is something between Asus and Intel module in thinkpad.
Any ideas what can I do to find out what is happening - and solve the issue?
many thanks for any input

Yes I did, clean install of wireless drivers. Last night I tried getting backwards, for now I'm using last driver from 2016 and it is better, but few hours speed drops again. Switching wifi off/on helps, but anyway the whole thing is extremely annoying.
I might also try ddwrt on my router, but I need few free hours to do it.

I also have a Lenovo T460s and have horrible connectivity speeds at 2.4 Ghz.
I have a 150MB connection service with my ISP.
The ISP's Tech just left here after installing a brand new Arris Router.
My T460s laptop tops out at just 11MB download at 2.4 Ghz but gets 167 MB at 5 Ghz.
When testing on my Iphone 6+ using Wifi Maximizer the 2.4 Ghz speed is 120MB download.
I ran the same test (speedtest.net) on my Wife's brand new Lenovo Yoga 260 and got the same terrible results, 9MB download at 2.4 Ghz and 171MB at 5 Ghz.
What is going on with the aweful 2.4 Ghz speeds on Lenovo Thinkpads?
