Gibson Research Corp.’s Shields Up port-scanning service at https://www.grc.com/shieldsup will test your router for hundreds of common vulnerabilities, most of which can be mitigated by the router’s administrator.
Free public DNS servers include Google, Quad9, OpenDNS, Cloudflare, CleanBrowsing, Verisign, Alternate DNS, AdGuard DNS, etc.
Here’s a short list of some of the most popular ones:

IPv6
OpenDNS 2620:0:ccc::2 and 2620:0:ccd::2 Google 2001:4860:4860::8888 and 2001:4860:4860::8844 Cloudflare 2606:4700:4700::1111 and 2606:4700:4700::1001.
If you have a slow ADSL broadband the first thing to do is eliminate a faulty line coming to the building. The best way to test this is to run a Quite Line Test. This test is not the most scientific and relies on the sensitivity of the human ear. However your ear is very good at picking up noise interference when it is supposed to be dead quiet.
This test pin-points interference between the Exchange and Master socket (the demarcation entry point into the building).
