Have installed latest firmware off Tp link uk site version 200624 which states recommend upgrade.

However after upgrade the Internet connection light stops orange, all other lights are white & dsl line is detected. Going in to the router shows as 0.0.0.0 in lan block under advanced tab. Have fully reset using the rear button & switched off router for over 30 minutes. No conmection with Isp is made, have reverted back to firmware 200227 and router connects with no issue. Would appreciate if anybody can assist or have the same issue using vdsl connection through internal modem.
