Unable to connect to internet via router (Tp link 740n)

  1. The router worked fine in the past until recently, my ISP had a break in the cable line and repaired it.
    Now, I am unable to connect to the internet.
    If I connect the ISP's LAN cable directly to PC (windows 7) and do the following steps:
    1. Control panel > View network stats and tasks
    2. Setup a new connection or network > Connect to the internet > Next
    3. Broadband PPPOE > Next
    4. Type in username, password > Connect

    Internet works fine. This means there is no problem with the internet connection.
    However, if I connect the ISP's LAN cable to the "blue" port of the router

    and the short LAN cable to my PC then do the following steps:

    1. Open http://tplinklogin.net/ (It shows me router config page)
    2. Click Quick setup > Next
    3. Select PPPoE > Next
    4. Type in username, password > Next
    5. Leave the Wireless Page untouched > Next
    6. Click Reboot (Wait till router reboots)
    It does not work, the router page shows "Connecting..." but does not connect at all.
    Here's the router log:
