ER605 not connecting to Internet thru Cable Modem
I am having trouble connecting my ER605 router as desired. I am only able to access it's admin interface and have it assign me an IP when another router is presently connected to same modem.
I have internet service through Spectrum. My modem (provided by Spectrum) is a Technicolor TC8715D. I have tried to connect the ER605 through the TC8715D managing the router via Standalone mode as follows:
- powered down the TC8715D
- powered down my old router (a Linksys EA9200)
- connected the ER605's main wan port to the same TC8715D port I had been using for the older router
- powered up the TC8715D and the ER605.
The ER605's SYS light never comes on and I am not able to access the admin interface. (via the admin address)
I've tried multiple cables - each of which I verified have worked for the Linksys router. I have found that if I also connect the Linksys router to another of the TC8715D's ports and power it up the ER605's SYS light does start to blink slowly and I can access it's admin interface and it does get a connection and assigns my laptop an IP.
This is not adequate though because I don't intend for the linksys to be connected directly to the modem anymore.
note: I have also seen another behavior. During one sequence of reconnections and restarts I did not restart the modem but cycled both routers and had reset the ER605 and in this case I was able to access the ER605 admin but it would not connect. The WAN was setup for DHCP/Dynmaic IP but the router did not seem to have a connection. The connection status was listed as "dial-up failed".
I expected there might conflicts with the LAN setup if I had both routers connected but I did not anticipate having trouble working with this router without any other router present. Any Ideas?
Thanks for any assistance
