Linksys Velop

Speaking from personal experience, Linksys Velop routers are absolutely terrible, and I woulnd't recommend anyone buying them. They're more expensive, less feature-rich, and a pain to setup. One of the pains is the app, Linksys wants customers to use their app instead of the web interface, but not only does the app not show all the features of the router, it's slow and buggy (at least on the android app, never tried ios app).

Web Interface

192.168.1.1 is the default gateway for the my velop routers. After entering this ip and clicking through the https warnings, you'll most likely be greeted by the download page, where it directs you to download the android/ios app:

At this point, your url will be something like https://192.168.1.1/ui/1.0.1.2229/dynamic/velop/blocking.html , simply replace dynamic/velop/blocking.html with dynamic/login.html#casupport and it'll show you the login screen
