The EBR is a G only wireless router. I would presume that the upload speeds will not be much over 1-2Mb at most. Your EBR is old generation technology. If your using the Actiontec as your main host router, you best bet would be to install a new generation WiFi AP and use it as your main host WiFi AP:
D-Link DAP 1360, 1513, 1522, 1525, 1533 series are some of the home and small business class devices.
If your needing more connections for wired LAN devices, install a external GB network switch to add more LAN wired devices to the network if you need.
