I'm using a Negear WNR1000v3 router for FTTC, and it's currently running the Plusnet firmware it was shipped to me with. I'm having some problems with random disconnections, and have tested with another router to confirm it's the Netgear that seems to be causing the connection drops. Having looked online, it seems some Netgear firmwares have this problem, so I'd like to try upgrading the firmware to a later version. However, I'd like to have a way back if this doesn't solve the problem or if it makes it worse, so I'd like a copy of the Plusnet firmware first, in case I need to reinstall it. Does anyone know if it's available, and where from? (It's version v18.104.22.168_53.0.66B1).
