Broadband keeps dropping on windows laptop

Hi All, 

Been working from home for a while now and my internet connection on the work laptop keeps dropping for a few seconds several times throughout the day it does not happen when gaming or streaming TV. I've rebooted the hub (V4) and hard wired it but its still happening. Online tests all show ok? work have investigated and advise its an issue with the hub or the connection. Can anyone help please?

Re: Broadband keeps dropping on windows laptop

Do other devices drop at the same time?

Re: Broadband keeps dropping on windows laptop

thanks for the reply, no other devices drop but could that be because they buffer and my work system does not?

Buffering is usually a sign of a dropped connection.  Some Corporate VPN's will drop the line if it's interrupted even for a short period.

Post your Downstream, Upstream and Network log. Use copy and paste, do not use screenshots.

Also setup a BQM here www.thinkbroadband.com/ping  for comment.
