I have tried many things to get a new Yoga 910 laptop on my RT-AC5300 wireless. The router is rock solid until the Yoga 910 connects via wireless and BAM: both the Cable Modem and Router become unusable. The Router Admin UI is not reachable, and a simple reboot will not clear the problem. I have had to do a factory reset 3 times now on the router.
I have turned off Wifi Sense and Hotspot 2.0 options as well.
I have reset the network adapter, flushed DNS, flushed ARP, etc. etc.
I have updated drivers, searched for similar problems and get nothing.
The WIRED connection on the new Yoga works fine.
Solved! Go to Solution.

**UPDATE** - I went "Defcon 1" and did a complete wipe of the 910. Setup from scratch, and WIFI was working fine. Connected to the USB-C dock for the first time, and drivers were installed, etc. Dock connection worked but screens were cutting in and out. Updated Dock Drivers. Screen flicker went away. Disconnected from Dock back to WIFI and BAM. This time, I had to put router in recovery mode to restore it.
I see an RMA in my future. This is less than one month old.

We already have a few threads going on this issue.. some with some solutions. I'd suggest this one, as it's where I posted MY fix. Haven't heard from anyone who's tried it and not had success resolving the issue.
Before doing anything, dig through your error log and note anything you have a lot of red flags from.
Start > Event viewer > Windows logs > System
Look for DCOM errors.
This way, you'll know if your problem is similar to others.
Keep us posted.

Yep. That’s the issue. You gotta fix all those DCOM errors. Windows update fouled the Qualcomm WLAN Installer program. The permissions on all those registry keys were not properly returned. I fixed most of mine by hand. Time consuming, but it fixed the issue.
Might be be easier to wipe the computer again and uninstall the Qualcomm installer BEFORE letting it see the internet. All works until Windows updates.

Well, DCOM errors were not my problem. Turns out that I had been looking @ the wrong piece of hardware. I thought it was the PC or how the PC interacted with the router. The only piece of hardware that I DIDN'T look at (until today) was the USB-C Dock. With the PC disconnected from both WIFI and the Dock, and the Dock still powered up, it froze my router until I unplugged the ethernet cable.
I configured my system to turn off the power source to the Dock when I remove the PC from the USB-C cable and have had NO issues since.
What a strange one!
Thanks gents for trying!
