3rd Party Router for Blocking?

Hi guys, want your best opinion/advices!!

I'm currently using PLDT Home Fiber and more than 10 devices ang naka-connect but the problem is I want to check kung sino mga naka-connect. Right now wala kasing option for blocklist sa admin website ng PLDT. Also have no idea about 3rd party router.

Any advices or 3rd party router would you recommend?

Thankies sa help!
