I have just bought a Dlink DSL 2750U router. I have the desktop computer connected with it through Ethernet and my laptop (Atheros N WiFi with the newest drivers installed) is connected via Wi Fi.
When the laptop is just next to the router, the file copy process from the desktop to the laptop, gives 10 MBps (80 mbps) which is very acceptable for a 150 mbps connection.
Now, when I take the laptop to my worktable downstairs, which is just two brick walls to cross for the signal, the signal falls to 2 bars (poor) and the speed falls to 1 MBps (8 mbps) which is very, very unacceptable for a proper dual antenna N300 router.
I made two parabolic reflectors with precise calculation. That increased the signal strength by a bar, and the speed by a small margin.
The strangest thing is that, when I decrease the router transmit power to 20%, the signal strength stays the same as 100%. The speed too stays the same.
What is happening? Please advise.
