Major Network Flaws, Need Help

[Helloman]

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!


EDIT: 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.

does the DVR have an address that starts with 169?

Do you have your Desktop run with obtain an 'IP address/DNS address automatically'?

Check that your Switch does not have a DHCP service running.

 

What IP address does your wireless clients get (IP/DG etc)

Just to clarify - you expect the unmanaged switch to negotiate 1gbit when connected to a 100mbit switchport on your router?

I am not aware of any unmanaged switches that can do that - they "always" negotiate the speed of the slowest device for all ports to avoid ram issues.

 

My guess would be that one of the cables are either the wrong color, the RJ45 connector does not work properly (the wires might not have been pushed all the way to the end of the connector) or that the ethernet cable is broken one or more places.

Have you tried with a different cable?

 

Does the DVR work when connected directly to your router?

 

There should not be any protocols blocking DHCP.

 

Your router might have set a DHCP scope to only allow a few or one ip to be leased at a time - does it help if you restart the router and then the switch and then the dvr in that order (letting them boot before you turn on the next device)?

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".

Certainly not the cables.
