I cannot seem to connect to the COM port with Putty. My cable has RXD which I put in the middle, ground to the left and TXD to the right according to the image. I then check the COM port in Device manager but Putty cannot connect. I want to remember that there was a better guide for this a couple of years ago but I cannot seem to find it any longer.
Am I doing something wrong here with the cable? I did rescue this router once with it before I just don't remember how I did it.
If it's an older Prolific chipset adapter, you may have to install the fake P*2303 drivers or whatever it is. I have, among the rest, one of those cheap cables that is no longer supported that doesn't work without manipulating the driver in Win10, but works in Linux just fine.
Yep, I did boot Linux from USB and it worked straight away!
Managed to get it into flashing mode and flash Stock Netgear again and then I installed DDWRT so now everything works again!
