A better recommendation is to use Cloudflare for one of your DNS servers and a completely different company for the other.
What are you trying to do on your wifi?
If you aren't using their DNS, then your network requests just get dropped (as you're not approved yet). You need their DNS to learn how to access their captive host so they can whitelist your mac address.
- frequently capture portals only permit access for 1-2hr. Your internet get cut off, then you have to realize its not a temporary issue, but portal issue, then you close the vpn, try to find the captive portal, and re-auth.
- latency is too high for my home vpn when I travel in asia
