Hi,
I will just jump right into the heart of the problem. I have a wireless network set up at our shop with a 4 port switch to allow wired clients connectivity. This was primarily because the switch on the router has only 10/100, and I wanted full 10/100/1000 for the security system DVR. The issue that occurred after I ran and custom cut all the cables, installed the switch and DVR is that only the router gets connectivity. The switch is an unmanaged GS105, the router a rather obscure "AirRouter" supplied by the ISP, which is Atlas Networks. The router works, and all wireless clients can easily access the internet. However the DVR has assigned itself an IP address different than the external or internal ones, and my desktop has an IPV6 and IPV4 dress, but no default gateway, DNS suffix, and the media state is "disconnected". Any ideas? Help! Upon testing with the switch out of the equation, my desktop now connects to the internet. Is there some protocol blocking everything but the router? Everything has link LEDs, and all of them are illuminated as they should be. However, the DVR still will not connect.

So, I took most of the gear home, trying to eliminate if it was a local issue. I ended up grabbing the switch, DVR and the two cables I was using and taking them home with me. I first patched the DVR into my network via the RJ45 ports on the back of the primary router. DHCP gave the box an address and we were good to go, the DVR was connected and actually able to stream live video. I then pulled out the GS105, which does seem to support multiple devices running at different speeds, and indicted the speed through the link LEDs. However, all devices on my network are gigabit capable (or above). Sure enough, the primary and secondary routers were able to run the LAN, but not the WAN, giving me no connection ability to the internet whatsoever. So, I connected my primary desktop, thinking the on at the shop might have been broken. Sure enough, same problem. Network diagnostics reported 2 things: "Local Area Connection" doesn't have a valid IP configuration, and "The default gateway is not available".

Hi,

The problem is that DHCP is not getting to the computers plugged into the switch. If that is a ProSafe model, you can download the ProSafe Plus Switch Utility from NetGear and ensure that DHCP is enabled. If it is not, then your switch is configured with a static IP which is not on the same subnet as the rest of your equipment (ie. 192.168.0.299 vs. 192.168.1.299). Those two addresses will not speak to each other on a local LAN without modifying your subnet mask.

The easiest solution is to download that utility, and ensure DHCP is enabled. That will force the switch to go to your DHCP server (presumably the router), and obtain a local network address. That will also allow devices connected to the switch to pass through the switch to also get a local IP from the DHCP server.

Agree with the 2nd post, that it must be an DHCP problem. Are you sure the custom cut cables all work properly, as that will cause issues, especially if the one between the router and switch does not work.

Tried plugging the devices into the router just to make sure that they get an ip?
