After my old ASDL router bite the dust I picked up a TP-W8968 ADSL Wifi router. Being a geek, the first thing I did was open the settings and start configuring the options, one of these being the firmware upgrade. However, what I didn't realise was the the UK version of the TP-W8968 router comes flashed with a custom firmware which includes configurations for most the UK's ISPs. Flashing the newer firmware downloaded from TP's website wiped these handy configurations.
After a fruitless search I emailed TP directly and they emailed the UK firmware that ships with the device. I'm hosting it here so others who need it can get it.
