Region : Venezuela

Model : TL-WR1043ND

Hardware Version : V1

Firmware Version : 3.13.15 Build 140319 Rel.41339n

ISP : CANTV

Hello, I have a TL-WR1043ND and I updated the firmware and all was successful, then I have tested my speed connection and I saw that my speed connection is really slow 0.04 Mbps, then I tested connecting direct from my ADSL modem and tested the speed connection again and the speed was 1.4 Mbps this is my normal speed because my ISP give me this speed.
Then I checked my IP and took the same values and set in the router as Static IP and I test the speed and I got 1.4 Mbps then I change again to Dynamic IP and test and I got again 0.04 Mbps.
Does someone have any idea about why this happen?

Thanks in advanced
