For most non-technical people this is irrelevant. Even if the router supported OpenWRT, they wouldn't know how to install it, let alone how to configure it.

Luckily, many (but certainly not all) continental West-European ISPs allow you to lease a Fritz!Box or you can buy one in a store and hook it up [1]. Perfect router/modem for consumers (not too complicated), can be configured through a web interface, and the hardware and software is developed by a German company.

[1] Many European countries have router/modem freedom, so an ISP cannot block you if you want to hook up your own gear. E.g. quite some tech people here use their own XGS-PON fiber ONT or at least their own router + modem.

The British ISP I tend to recommend gives you a Frtizbox (included with monthly package with 12 month contract, but becomes your property), but most will include a router with their package, usually a rubbish one, and most people do not care about having a good router.

And who do you recommend?

[graemep]

Zen for most people. Reasonable pricing, good customer service, reasonable latency and a good router.

I was reluctant to recommend them by name because I know there are other good ISPs, some are cheaper, some are more expensive, some operate only in certain areas (if they do not use Openreach local loops).

While the Fritz!Boxen do indeed work for dummies, they are rather noisy, with no option to stop that noise.

Just the last one, out of gazillions. It's a proprietary protocol for finding their other proprietary stuff in the LAN for home automation, meshing (also proprietary).

It's also almost useless for more complex internal setups.

Rather logspammy if you ask me.

One doesn't have that with other, more technical options. There is also less and less need for the "DSL- (or cable-) modem part, since fibre tends to be plain old ethernet.

Also the ownership of AVM recently changed. I fully excpect ensuing enshittification.
