XPS 13 9300 WiFi Random Disconnect.

Question

Received my new XPS 13 in December. 2 months later and I am still having WiFi disconnect issues.  This morning I opened up my fully charged XPS 13 and within minutes it had disconnected from the WiFi so, fed up with this, I decided to post on this forum. I have many years experience designing, implementing and debugging WiFi networks and I was hoping it was just a WiFi driver issue that would be easily fixed but even though I have run the Dell update system and updated all software the problem still remains. I have read many posts on different web sites over the last 2 months for an understanding and resolution but to no avail. Solutions ranging from changing drivers, removing the Killer app, power settings, registry settings - I have the tech confidence to do all these things but what should I trust?  This was a £2k + purchase and TBH if it wasn't for lockdown I would have returned this laptop to Dell and purchased something else. It would seam that the Killer WiFi has had this problem for a long time. Frankly find it disgraceful that Dell have not invested time to resolve it and just post a simple solution for all. Dell you need to step up and do some very robust testing of your WiFi chip and the drivers then post the solution for all.

Having the same issue. Why has there not been any resolution on this?

Came across the issue this morning after updating to the latest windows 11 version yesterday

Tried flushing DNS, which is still touch and go at the moment. To add to this, I have restarted the adapter in Windows 11. Certain websites are loading, while others aren't. This is not because of any firewall blocking the connection at all, I'm literally doing this on my old laptop with the same settings, and every website opens up without fail.

Please assist urgently in resolving this issue?
