Hm, as you got disconnected in the same way using a mobile data connection I’m wondering if it’s a local system issue. Perhaps a running background application is interfering and causing a connectivity issue. Bit of a shot in the dark, but if you try a Selective Startup and disable your background applications is there any improvement?
- Press the Windows key
- Type ‘msconfig’ and select ‘System Configuration’
- On the ‘General’ tab, select ‘Selective Startup’
- Deselect ‘Load startup Items’
- Reboot your PC
If the issue no longer occurs after having performed the Selective Startup, try re-introducing your programs one-by-one to determine which is causing your issue.
