I got a Thomson SpeedTouch 510v6 gateway and DI-514 wirelss router. But when I used only the Thomson Speed tourhc 510 v6 gateway, it is working well. However, when I connected the modem with the router according to the manual of DI 514, I can not get access to internet anymore. I also go to the dlink support website and reset all the stuff under the guidance,still not working. Comments are greatly appreciated!
