Strange Intel WiFi chip behavior with Windows 8.1?

Question

Iron

Good afternoon!
I ran into a strange problem: when a Sony laptop is connected to a wireless network via a built-in chip (Intel, I won’t name the exact model now), a collapse occurs in Windows 8.1: after 5-10 minutes after connecting, the network drops (all devices fly out of it and can no longer connect not just a laptop). I checked the artifact on 4 networks - it's the same everywhere, only restarting the router helps (in case of distributing the Internet from a poppy, reboot the system). The exception is industrial networks (cisco routers, for the entire building). The artifact manifests itself from the very purchase of a laptop. The drivers are the newest, all the recommendations from Sony technical support have been fulfilled, a lot from Google too. As a result, you have to use an additional whistle, which is inconvenient.
What is most interesting - the second system is Xubuntu. And she has no such problems at all.
Has anyone experienced similar behavior, please let me know.

Answer 1

And I see that 8.1 does not quite adequately work with WiFi. The chip is different, and the problem is somewhat different, but still try from this answer:
Why does the Internet constantly disappear on a laptop when working via Wi-Fi (Windows 8.1 + Broadcom + TP-link)?
They advise to roll back to the old version. And there is also a link to the f1comp.ru resource. Maybe look there?

Answer 2

I didn’t quite understand your explanation, does the network crash on several PCs? or how? if it crashes only on your laptop after purchase, you can try to roll back the Wi-FI driver to an older version! If the network drops on several devices, then there is another problem in the router itself!
