Find the problem
What DNS am I using, and is it the problem?
Half of "the internet is broken" is really "the address book is broken". Finding out takes one tap, and testing it takes one lookup.
1. See your servers
Open Radien's status card, then Network Details. The DNS row lists the servers your phone uses right now - usually your router or your provider, unless you chose others.
2. Ask them a question
Open DNS Lookup and query a common name (any site you know). The system resolver answers with addresses and timings - or it does not.
- Answers arrive: your DNS resolves names. If browsing still fails, the problem is past the address book (see Wi-Fi connected but no internet, for the ladder).
- Timeouts or errors: your configured resolver is down or unreachable. One more check separates "DNS is broken" from "everything is broken": ping 8.8.8.8. If pings flow while lookups fail, DNS alone is the broken piece.
3. The comparison, if you want certainty
With Radien Pro, the same lookup runs against Cloudflare, Google or Quad9 in one tap. If public resolvers answer while yours fails, the verdict is precise: your resolver, not the internet. And if the answers differ between your resolver and the public ones, your network or provider is filtering or redirecting names - worth knowing, whatever you decide to do about it.
What you now know
Which servers answer your phone's questions, and one of three verdicts: the resolver is broken (change DNS in iOS Wi-Fi settings or on the router), the connection is broken (a different page's problem), or DNS is innocent and the trouble lives elsewhere.
The first checks run free in Radien; the one-tap resolver comparison is part of Radien Pro.
