I have a randomly generated password for my wifi (mostly historical reasons), but I hang QR codes around for it. Unfortunately, not enough devices support that sort of thing.
I don't think I could ever go back to an off the shelf router anymore. Years ago I set up a pc with pfsense, hooked that up to a switch for my wired devices plus one to the wireless access point I bought from ubiquiti. Almost zero issues after setting it up, plus it's much more flexible in that if my wireless dies, my wired devices still work. Or a component in the PC dies, I can just replace the part instead of the whole router. Takes some networking knowledge but really nothing you can't learn from googling.
... with every replaced part and yearly power consumption costing as much as a new conventional low-power router? If the only thing it does is routing packets and you don't run any heavy services on it, there are low-power, compact and cheap openwrt routers out there.
I get the point of the meme, but can I just say I hate routers that give you a default password other than admin or password. Like I get the point of it is to prevent the device from being insecure when the user doesn't put a password on it. However after a while the back of the router becomes basically unreadable and when you go online and search default admin password for x and their support page says that the password is different per router it's a little ridiculous. It is a much better approach to just force the password to be changed when you do the initial setup that way you can forget the admin password and factory reset it and still be able to access it where with current day routers if you reset it and you don't have that little piece of plastic on the back that says the admin password you're more or less SOL
Mines behind our printer, it gets covered in dust and the adhesive on the sticker is starting to fail lol, thankfully it's not one that does that though so I'm not too worried.
