Well, @passenger@sopuli.xyz mentioned that it’s on the google page. But then when I chose some of the brands under “Find specific steps for your access point”, it’s a bit useless because manufacturers web admins have no sense of discipline or self-control. They cannot resist the urge to rearrange their website which broke Google’s links. But further below on Google’s page are some general instructions. I would try to follow those. And if you get stuck, maybe try posting a support request in !homenetworking@selfhosted.forum.

(update) I just had a closer look at the general instructions to do a quick sanity check. Google’s instructions for linux are bad at the 2nd step. That is, running ifconfig as a linux user can be tricky… might need to run /sbin/ifconfig instead. And even if it runs, it does not give the gateway anyway.

If you’re on linux, run ip route instead, which will say something like default via 192.168.1.1. Whatever IP address is the default gateway, that is what you need for the next step. Note I am only talking about linux. Google’s instructions are probably fine for other platforms.

Very happy to have learned about tildeverse.org. It gives a great refuge from a lot of the garbage. But I have to ask, if you are part of the tildeverse project why are you on lemmy.world, a centralised exclusive Cloudflare instance? I realise tildeverse does not have a lemmy node but there are many decent ones and LW is probably the most contrary to the tildeverse philosophies.
