NHCheck Lite
Five checks, one page.
Your connection is slow. NHCheck Lite runs five real measurements in about thirty seconds and names which one is at fault — the Wi-Fi in the room, the router, the line out of the house, or the name lookup. Free, on Android.

The five checks
| Wi-Fi status | Signal, channel, interference and security — and the clearest channel to move to. Off Wi-Fi it judges the mobile link instead |
| LAN gateway | Eight echoes to your router, then a sweep of the network behind it: a fault here is inside the house |
| ISP gateway | The first public hop past it: a fault here is on the line |
| DNS lookup | A name resolved and timed |
| Speed test | Real download and upload, eight seconds each |
Every check performs a real network operation — nothing is simulated. Each ends in PASS, WARN or FAIL, and whatever fell short comes with the fix behind it. The run closes by naming the culprit in one sentence, taken from the earliest failure along the path rather than the loudest number.
Two rows open further: the Wi-Fi row into an analyser that draws every network in range over the spectrum it occupies — or, on mobile data, into the operator, band and cells of the mobile link — and the LAN row into the list of what answered on your network, each by the name it publishes. Both are described in the documentation.
