Hi TPG, My Connection getting very unstable, some of the device connected and some not. Everytime this happened i need to reboot the device via http://tplinkmodem.net/, even the hard reboot from the device won't work. Not sure if this is related to the firm ware that I am using, which is very old. Please can you advise how I can upgrade the firmware?   Firmware Version: 0.1.0 0.9.1 v5006.0 Build 200810 Rel.53181n Hardware Version: Archer VR1600v v2 00000000 ... View more
