Guest Wifi - Anyway to disable browser popup?

[Technosense]

Can't seem to find a way around this. I run a digital signage PC for a restaurant and connect remotely to update etc. They've added me to the "approved" list of PCs that can stay connected but every 8 hours I get a browser popup like normal guests to "continue to the internet". which often pops up over the digital signage content that's playing and I get a call.

The owners say the "computer guy" doesn't know how to fix it.

I've closed the browser, it reopens after set time. I've minimized the browser, also doesn't work.

My question is, how is it triggering the browser to open? Can I disable this on the client PC?

Are you still having this issue?

Sounds like the ISP lease is refreshing every 8 hrs and you're getting a new connection to the Internet.
to confirm;

• log into the site router
• find the WAN side settings
• depending upon the make/model of the router, the ISP connection status will show when the lease was granted and when it will expire
