That would be for the legal system to decide. If you purchased it for a specific advertised feature, and that feature was disabled unless unspoken terms were agreed to, you would have a case.

For the downvoters, in the US:

The implied warranty of merchantability guarantees that a product sold to you will work for its intended purposes. In other words, it means you can expect a toaster to toast your bread. If it doesn’t, you have legal protection against losing money on a product that doesn’t work.

If you bought the router expecting it to work as advertised, you may make a claim if it doesn’t. They would have to spell out ahead of time what the limitations and requirements are in order to avoid trouble.

If I bought one of their routers and this came up, I would simply be returning it and giving the person at the counter a printout as to why. Sorry, but this router is not “suitable for purpose”. Look up that phrase and “merchantability”.

Did I miss anything?

I’ve got Mullvad on my Android and a Linux virtual machine for when I need a textbook that’s overpriced. That would be all of them.

You could run Kodi, Emby, or Plex and get local access through DLNA access.

I have a QNAP RAID set up that Emby catalogs and handles access for. An Emby app on my LG TV, and a Roku on other TVs. Some RAID systems will just plug into your network and allow you to install apps on them directly.

Another option is to use MediaMonkey to catalog and provide access. They even have an Android app.

Lastly, regular external HDD are meant for occasional access, not continuous work. Most have a duty cycle of about 25%, meaning they should only be run about that amount of time before dying. This is why I went with NAS HDDs. If you have the money, go with an expandable RAID. Once you start using that capacity, you’ll find you want more.
