  1. OS: Windows 7 64-bit
  2. Host router: TP-Link WR841ND 300Mbps Wireless N Router. ---> Emulator
  3. Repeater: D-Link DIR-300 54Mbps Wireless G Router ---> Emulator

Scenario: I have already flashed the DIR-300 with DD-WRT firmware successfully and set it up as a repeater. The mode I'm using is "Client Bridge". I'm also getting a full 5-bar signal.

Problem: I'm subscribed to 10 Mbps package from the ISP. I am only getting around half the speed or less from my DIR-300 repeater (anywhere between 2 to 5 Mbps) . On the other hand, I am able to get full 10 Mbps speed from the host TP-Link router when I'm near to it. Is this because I'm using a 54 Mbps wireless G router? Is there a way to fix that to get full 10 Mbps speed? Please enlighten me.

Alternative solution if the above cannot be fixed:

If I purchase the TL-WA850RE 300Mbps Universal WiFi Range Extender, will this provide full 10 Mbps speed?

Some speed is lost when going through a repeater because of the distance it travels but not as much as you are talking about. I would suggest setting up the D-Link as the main router and see what speeds it gets, if it doesn't improve then it is definitely the router.

I purchased the TL-WA850RE 300Mbps Universal WiFi Range Extender and I'm getting a 10 Mbps connection speed (full speed). Also, placing the old D-Link wireless G router at a higher altitude gave 70 to 80% of the speed (I overlooked altitude's significance), but the TL-WA850RE I bought gave 100% (also at a high altitude, around 3 meters above ground level). Thank you GeekyDewd. – Ugo Jan 12 '14 at 18:27

All "repeater" modes sacrifice half of the wi-fi speed for talking to the host and its clients simultaneously. See: http://www.dd-wrt.com/wiki/index.php/Repeater_Bridge (just above "Troubleshooting" section)
