Brand new E5-575G-53VG here, Windows 10, all up to date (just got today).

 

Will connect to some Wi-Fi access points just fine (Linksys at home, LG G4 Phone Hotspot), but not others (SonicWall TZ215W Firewall Wi-Fi and TP-Link WR-841ND it seems to fail to associate.

 

Really bizarre. Tried the latest drivers, tried older (11.0.0.492) drivers I found around this site, and tried with the built-in driver (seems to come with Windows 10) for the device -- all with the same result. Windows Event viewer seems to show it failing to associate, then Windows takes the initiave to disable/enable the adapter, and it never works. Here are the Windows eventviewer events as follows, in Windows > System pasted:

 

(Event ID 6100)

Helper Class: Auto Configuration
Initialize status: Success

Information for connection being diagnosed
Interface GUID: d024142b-e102-488f-9df5-844c66cdbd73
Interface name: Qualcomm Atheros QCA9377 Wireless Network Adapter
Interface type: Native Wi-Fi
Profile: Discovery connection
SSID: Sunshine
SSID length: 8
Connection mode: Infra
Security: Yes
Connect even if network is not broadcasting: No

Result of diagnosis: Problem found
Issue referred to: RNWF MSM Helper Class

Root cause:
Windows could not connect to "Sunshine"
You can try to connect again.

Repair option:
Resetting your wireless network adapter
This will disable and then enable the network adapter "Wi-Fi" on this computer.

 

 

Then it follows with events that disable, and enable the adapter, and point out that connecting failed. This whole process takes 6-10 seconds from clicking 'Connect' and typing in the password (and Yes/No to discoverable), and seeing that it Could not Connect in the Wi-Fi list.

 

These EXACT same messages are the same, regardless whether the 12.0.0.191 driver OR the 11.x driver listed OR the driver from Microsoft (4.x). Reboots in between changing drivers. BIOS up to date. Not sure where to go!

Thank you ahead of time, any helpers.
