ap.setup (some people type it “ap setup”, with a space) is the address you use to set up and log into certain WiFi extenders. Here's how to open it — and the real reasons it sometimes won't.
Connect your phone or laptop to the extender's own WiFi network (named WAVLINK-XXXX or ending in _Ext), then type ap.setup into your browser's address bar — not a search box. If it doesn't load, use 192.168.10.1 instead. Default login is usually admin.
This is the misunderstanding behind almost every problem. ap.setup isn't a page out on the internet — it's a local shortcut that only your extender answers, and only while your device is connected straight to that extender. Type it into Google and you'll get search results, not your device.
It also only works on a few brands: Wavlink, Comfast and Dodocool extenders use ap.setup. If you have another make, its address will be different.
Four steps, in order. The order is the whole trick.
Most "ap.setup not working" cases are one of these — roughly in order of how often they're the actual cause.
When in doubt, the numeric address does exactly the same thing and skips most of the above:
All three open the same login. If one fails, the next usually works.
It's the digits one and zero: 192.168.10.1. The letters “l” and “O” (192.168.l0.1) will never work.
Nearly all of them — from the small indoor plug-in repeaters up to the weatherproof outdoor units. Dozens of Wavlink models share this same ap.setup / 192.168.10.1 login, so the steps above work whether you've got an AC600, an AC1200, an N300, or a newer WiFi 6 (AX) model.
The login is identical across the range; what changes between models is the physical setup and the modes on offer. If you're not sure which you have, find your model in the directory. Outdoor units have a few extra steps (PoE wiring, mounting), covered in the outdoor extender guide.



Logging in is step one. These three take a minute and matter more than people realise.
