Old ADSL router as wireless access?

[doggone]

Any day now fibre will finally be available locally, All good obviously but can I use my old router as a repeater or something.
It currently has three security cameras linked to it wirelessly and a homeplug extender through ethernet.
I'm wondering as a temporary measure I can continue to run that with a link to the (imaginary at this stage) fibre router.

Anyone with Virgin Media already has this issue The supplied wireless router is shite so anyone with any sense or technical need switches it to "modem mode" and fits a third-party wireless cable router.

As to re-using your old kit that depends on how flexible the firmware is. I've definitely seen old ADSL routers where you can nominate one of the 4 Ethernet ports on the back as a WAN port and effectively create a cable router. Failing that if you can run OpenWRT or dd-wrt you can do anything you like.

Make and model of the old kit?

It's a Netgear DGN2200
The firmware is V1.0.0.57_7.0.57
I have seen some online comments about using a pirate firmware to unlock more features.
Until the fibre (only to cabinet mind) is up and running it seems rather too hypothetical to check what could work.

If the extender and IP cameras could still work on that older router somehow it might be a quicker solution than transferring them over as they have been up and running continually for about ten years and need some kind of chinglish software to arrange port forwarding and email alerts
It might be easier to get a couple of new ones.

My "old faithful" Netgear went down recently and my works (as we're all Zoom and code in your living room 'cos of Covid) sent me an Asus cable router and it was surprisingly easy to set up for port forwarding and the like, for a similar set of requirements as your own.

Just a note that, for the most part, the difference between a £40 router and a £140 router is how fast the WiFi works. If most of the essentials are running over Ethernet it's hardly worth splashing out the big dollar.
