Hai - If your previous device was a gateway (modem/router combo) then you will need an extra modem to go with you N750. If your old device still works, you can turn it into a DSL bridge. What’s the brand and model of your old device?
Read around and supposedly it is a locked version of a normal Netgear DG834G.
I was thinking of just buying a TP-Link TD-8817 as the modem for the N750
Would the TP work with the N750?
Reason I dont want to bridge with the Netgear is it has been a pain resently with dropouts and firmware cant be updated due to it being locked to provider.
I don’t know DSL, but after a quick look, as long as the TP-Link unit works with your provider, I think that it should be fine to use it with the WD router.
Most routers (like the WD) can work with any cable modem or DSL router as long as it has a network connection to plug into.
Make sure you know your connection information with the ISP. Whether it’s DHCP or PPPoE. If PPPoE you’ll need the credentials to put onto your new modem or router.
