Troubleshooting tools we actually use

Eight utilities built alongside our Windows, Android, iPhone and laptop repair guides. Everything runs on your own device.

Most tool sites are a wall of a hundred calculators nobody asked for. This is not that. Every tool here exists because we needed it while writing a fix guide — and readers kept needing it too.

Router admin page will not open, or your ISP is asking for your address

Why the list is short

We removed thirty-five tools from this page in August 2026. Most were calculators and converters that had nothing to do with fixing a device, and several pointed at pages that no longer existed. A visitor who clicks a broken link learns something about a website, and it is never good.

What remains is eight tools we have opened, tested and use ourselves. We would rather run eight that work than forty that do not.

How these tools handle your data

Seven of the eight run entirely as JavaScript inside your browser. The text you paste into the JSON formatter, the password you generate, the file you convert to Base64 — none of it reaches a server, because no server is involved. Close the tab and it is gone.

One exception. What Is My IP has to ask an external lookup service what your public address is, because your browser cannot see that by itself. Every IP checker works this way. We keep no record of the result.

Common questions

Why do I need my IP address to fix my router?

Your router's admin page sits on a private address like 192.168.1.1, not your public IP. But when a connection fault is being diagnosed — by you or by your ISP — the public address is what identifies your line. Support desks ask for it first.

Why is the location slightly wrong?

IP geolocation maps your address to your ISP's nearest routing point, not your home. Seeing a neighbouring city is normal and does not mean your connection is misconfigured.

Do you store anything I type?

No. Seven of the eight tools never send data anywhere. The IP checker performs a lookup but keeps no record.

Are these tools really free?

Yes. No paid tier, no signup wall, no usage limit.

Can I use these on a phone?

Yes, all eight work in mobile browsers.

Will you add more tools?

Only when a repair guide needs one. That is the rule that keeps this page honest.
