The wifi connection at home on my Thinkpad t450s laptop drops all the time. I am dual booting with Windows 10 and no problems exist there.
I suppose the problem is with the linux drivers of the wireless card. The wiki states, that they are some problems with the wireless card driver, which could be fixed by installing the updated driver, but this solution is only for kernel < 4.7
Any suggestions on what I might do?

You should probably disable dhcpcd.service
Let network manager handle it.

I think it is better. I hope it works fine now.

If it's fixed, don't forget to edit your first post and append [Solved] to the title.

I can confirm, that the problem is not fixed. I also tried to observe it more and define its behavior better. It is dropping in areas, where the wifi is weaker, but in the same areas my android phone connects without a problem and on the same laptop, but with Windows, everything works fine.
The current behavior is, that the wifi will disconnect every 5 seconds or so, then reconnect and then again after 5-10 seconds, drop again.

You could try to set a fixed rate on that device with iwconfig.
Disabling Power savings could also help.

Post a complete system journal.
5 second cycles sounds *a lot* as if there're still two services in a race over the NIC…

Here is a piece of the journal when the disconnection is happening until there is a connection to the network again.
I noticed this. It doesn't seem normal, right?

Sounds like a bug.
Try to disable https://wiki.archlinux.org/index.php/Ne … domization and if that doesn't work either, drop NM (stop & disable) and try to connect w/ wifi-menu and see whether that's more stable.
