Frequent disconnects on win 7 machine

Hello, I have 2 computers at home, a laptop (newer win 10) and an older desktop (win 7).

While on the win 7 I get constant disconnects - network disconnects, not game crashes.

While on the same wireless network while on the laptop I get -0- drops.

While playing on the work station (win 7) I run discord, other streaming apps which do not disconnect but the game disconnects every 5-15 mins.

So far I’ve also ran a continuous ping to the local and to my outside gateways with no drops.

Tried to reinstall battle.net application to see if that is the issue.

Win firewall is turned off - as is malware software just to make sure its not causing the issue.

Any thoughts what else I can try?

PS non battle.net games are not having an issue.
