D-Link DIR-601 will not let me use PPPoE for Wireless connection
Under Windows 7 pro. DSL Westell modem and D-Link Dir-601 router. I have the latest firmware upgrade for both the modem and the router. My ISP, (Centurylink), uses PPPoE. When I set up my router for this, my wired connections will connect but my wireless portable PC cannot. When the setting is changed to Dynamic IP (DHCP), both my wired connections and the portable will connect. If I power up JUST the modem and the router, both will handshack with all green lights on and with the modem lights solid. I then start the computer and everything seems fine until the computer has finished its boot. At the desktop screen, the modem and router both will start rapid flashing for a good five minutes before they settle down to let an internet connection be made. When the modem and the router finishes their handshacking, the internet will then works but the speed is very slow, about 1/3 from just the modem connected. This happens even when the internet connection command is set to disable. This is a new wireless replaced router. I had it replaced because I though the first one to be bad. I replaced a wired router with this wireless one. The wired one was set up with PPPoE and worked perfect. Thank you for anyone that can help me correct this.
