Yes, this is what I've noticed with consumer, ISP-provided routers in France. I think it's a rather good thing, although those same routers usually come with UPnP turned on...

It's a consumer router if you can buy it. If only your ISP buys it and they give to you, it isn't a "consumer router".

This has nothing to do with the router and more to do with your ISP. I had a UK provider which did that, but it was easy to swap their router (I did have to give them a call though). Here in Portugal the ISP-provided router was fine, so I am happy to use it.
