Router Won't Assign IP Address

[RyanR]

I've hooked up a 2DS for the first time.

When I log into the router, I don't see Envisalink listed. I've tried rebooting the router and then rebooting the 2DS, no luck. I've tested the ethernet cable and it is good. I've let the 2DS sit there connected for hours and it still won't get an IP address.

LED's:

- KEYB flashing
- OPER flashing
- ACT flashing
- LINK on

Router is D-LINK 655.

Any ideas?

This is almost always a cabling issue, although I've also seen a bad port on a switch too. Make sure you have a link light on BOTH the '2DS and the hub/switch that you are connecting it too.

Try a known good cable, and try a known good port.

Doh, I wonder if it's how I have my router and switch set up. Let me describe, and maybe you can tell me if that's where I went wrong.


Here's how I have things set up:

Modem --> Switch --> Router

In terms of the 2DS

Modem --> Switch --> 2DS

The router does not have a line going from itself back to the switch. The reason it's set up like this is because I have a structured wiring panel in the basement (with modem and switch) and router on main level to improve wireless signal strength throughout the house. This is a new house, and I haven't even verified that the switch is getting my internet connection out to the ethernet jacks throughout the house. Wireless works on the router just fine of course.

I might need to move the router back down into the panel and have it output to the switch. Ethernet routing is not my strong suit I'll admit...Not entirely sure how the modem, switch, and router are supposed to interconnect


You mentioned the cable possibly being bad. I know it's definitely not the cable. I've tested the cable, and it works.

Yeah, its the setup. You need to have the '2DS behind the router in order for it to get an IP. You need

Modem->switch->router->2DS

Thanks, I'll give it a shot when I get home after work today and follow-up.

I didn't want to have to put the router in the basement, but I guess I've got to. Add a wireless booster to the list of things to buy

I have something similar set up with my structured panel.

I set the wireless router up so that DHCP is disabled, and moved the cable over to one of the 4 ports. Now its transmitting as purely a wireless access point and not trying to also give out IP addresses.

If you can get the 2ds to the router by linking one ot the cat5 lines then you will get it working.

Happy to report that it works by putting the 2DS behind the router, as suggested by GrandWizard. Thank you very much for your help!

Ryan, generally, in any type of network setup using a cable or DSL connection, you MUST always wire like this:

Modem >> Router >> Switch>> Devices

Your switch /hub etc...can not talk to the Internet or the modem. It would always be the router talking THROUGH the modem to he Internet.

The switch is only there to allow many devices to connect to the router. Think of the switch as nothing more than the ports on the router. All it does (unmanaged switch) is give you the ability to add many devices to those ports. A managed switch allows you to do many things, like segregating LANS/SUBNETS etc...but they are not capable of addressing the Internet.

In your case, like mine, you could place the router downstairs with the switch and the modem, then simply add Wireless Access Points (WAP's) through the rest of the home, which connect via Ethernet, to the switch. T

here are routers you can buy instead, which can operate in WAP mode, or bridge mode etc...but what I did, was purchase 5 of the D-Link DAP2553 WAP's and place them throughout the home. They all plug into the switch and use POE for power. Very clean, incredibly fast with a real 300 mbps throughput. I can upload to the web at 2mbps and download @ 32 mbps, all through wireless. I have 3 Cisco layer 3 managed switches and a Fortigate firewall managing 2 separate WAN'S in the home, including many VPN tunnels. I do it the way I am suggesting you structure it. The WAP's are cheap and have excellent coverage.
