I picked up a Netgear R6300 v2 Smart Wifi Router to plug into my Arris TM1602 Cable modem, because the latter has no wifi and is limited to one IP address at a time.

Unfortunately, with this model router having come out four years ago, neither Amazon nor Newegg had a new one; only refurbished. It turns out the one I got was supplied to its previous owner by Charter (Spectrum), and its firmware is tailored to them, meaning I cannot upgrade it through Netgear, and Charter will not help, they only scream at the top of their lungs, "You have to go to Netgear!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

Now, a Netgear tech support agent who helped me get to the root of that, told me that he is sure that despite the firmware being outdated, it does not pose a security risk. So I decided to keep the router and use it as is.

All this being said-- I've heard that there is a way to re-genericize the firmware so that it can be upgraded again.

So I've come here to ask:
1) Is this true?
2) If yes, does anyone here know how to do it?

I think it had something to do with "DD-WRT," which I'm not familiar with.

I am wondering, why not just purchase a new router rather than a four yr old refurbished router? To me, that makes no sense. Routers wear out just like most other parts AND old routers can be a security problem.

To answer your question, yes you can flash the router with open source firmware IF your router is listed on the support page for that firmware.
Just checked the DD-WRT database and yes your router is supported.

I have not used a netgear router is a LONG time however most normal routers would be updated via a browser logged into the router. You would have to do a manual update. Here is a pic of my router with the manual update circled in red. After you download the firmware, you would point the browser at where you saved the firmware and tell it to update. Again READ ALL of the instructions and be sure you know what you are doing. There is a very real chance of bricking a router from a bad firmware flash. Most modern routers are dual boot in that there are two partitions on the router so you can boot the backup if there is a problem with the primary.
With a linksys type router, you cycle the pw switch five times and the backup partition would boot. Again I have no idea IF your router has a backup partition OR how to make it boot.

As to why I got a four year old router-- I didn't know it was that old until I started investigating the firmware issue. Completely new hardware is simply out of my price range; for me, it's get old stuff or do without altogether.

I'll read the stuff you linked before making a final decision on whether to try it or not.
