Solved Netgear 3700 router/modem dual ADSL and Cable connection

February 4, 2015 at 01:21:33
Specs: Windows 7
I have a Netgear 3700 router/modem.
Currently connected via the Ethernet to a cable modem. I wish to also connect an ADSL connection giving me two access points to the Internet. The Netgear option for WAN access is set to auto-detect. If both Cable and ADSL connections are running which would the Netgear use?

Page 20 in the manual states either adsl or Ethernet. You can't use both. There is also no load balancing/line failover feature like you get with a dual wan port router.

End of story.

You can't do that setup with that router because it only has 1 WAN port. You need a dual WAN router, which has 2 WAN ports.

I have not used this one, but the Cisco Small Business RV042 VPN Router is one option. A google search for "dual WAN routers" will give other options.

Thanks for the feedback and wonder If I get this right?......
The ADSL connection is via the RJ45 socket, the cable modem feeds the WAN port. Are you saying only one is recognised at any one time? If so I thought the setting for the WAN being auto-select would choose, my OP was asking which one?

The modem- router I have is 3700 v2.

That is a cable modem router combination. It only connects to the internet via cable. You can not use the rj45 lan ports for the adsl connection.

As pointed out by FishMonger you must get a dual wan port router. You will also need a cable modem in addition to the dual wan port router. You could use the 3700 as a modem but would need to put it in bridge mode

Thanks for the feedback. On the rear of the 3700 there is a socket labelled ADSL into which I can connect my phone line via the filter. The WAN port is currently connected to the cable modem via an ethernet cable. As I understand it either of these can be used for connection to the Internet. On the router there is the option to set the WAN access to auto- select, cable only or dsl only. From this it is set to auto detect, so if both ADSL and WAN connections are running which will the router use? The Netgear manual does not specify or provide any information. i cannot try this as I currently do not have an ADSL line. Hope this makes the OP clearer.

My feeling is that dsl would get preference by default, the ethernet port being more often intended for uplinking another hub etc. ?
