Just received 1st email from the Tech Support of
D-Link as follows.
From the email it seems you get slow speed when the
router is in PPPoE mode, and the internet speeds up when the router is in bridge mode.
You would like to have the router configured in PPPoE mode.
Ideally the mode of the router should not affect the speed you are getting.
Kindly keep the router configured in PPPoE mode, and follow certain steps mentioned and observe the improvement in the Internet speed.
Assign a static IP address to the adapter in the subnet range of the router, with the default gateway as the router's IP address.
Verify the
DNS IP addresses provided to you by your ISP and assign them to the adapter.
Try to ping the GLB router and check the reply. Try accessing internet and verify the speed.
I had already assinged static ip to my lan card and also cheked the ping and dns
