Can't obtain new DHCP connections
« on: March 18, 2010, 11:36:11 AM »

Hi All-

Ran into an interesting problem the other night. My home network runs 2 PCs, 1 wireless printer and a NAS that are connected to my 192.168.101.x network. Router is assigned 192.168.101.1 as gateway. Last night, I attempt to get on to the internet and no connection. Check my IP and it's 192.168.0.203. Same with the other PC (192.168.0.204). Rebooted router and cable modem, ran ipconfig/release and /renew, same thing. If I set static IPs, still no good. If I change the ranges to 192.168.100.x and make the router 192.168.100.1, it works if I assign static IPs.
Was running 1.21NA firmware, upgraded to 1.22 and issue hasn't gone away. Any ideas?

Whats the Status say in the WAN section of Device Info? This will tell you if you have a connection or disconnection. There should be an IP there starting with 2 characters, ##.###.###.###. If your not seeing any IP or it says disconnected, there could be an issue between the router and cable modem. Plug in a PC directly to the cable modem and see if you get an IP and internet as a test. Check cabling to be sure. Let us know what you find.

I tried setting my router back to 192.168.101.1, and changed my network connection to DHCP from Static. I couldn't connect to the router. Once I then set my IP to 192.168.101.x, I was able to connect to the router. The settings show Connected and Established.

192.168.100.1 is the default IP's of most cable modems. Setting your router to the same gateway as your modem will cause a IP conflict for sure. Question is, why are you changing the DHCP range from default? Do you have another router using that range? What subnet mask are you using, default? Seems like there is some background information missing. Perhaps if you let me know what your trying to do I can just skip to the solution rather then try to figure out the problem? Let me know.

Your 4500 can actually be any address you want it to be just as long as it's not the same IP address as your modems. I would do this first, do a reset of the router and let it get a connection to the Cable modem. It would auto connect with out changing anything. Once that's established, check ur PCs. They should connect and get to the internet fine. The routers default factory IP address is 192.168.0.1 with a subnet mask of 255.255.255.255 or 192. Once you can establish that the modem, router and PCs are connected and getting to the internet, then you have the choice of going back in can changing the routers IP address to something different. I would not change this if you do not have a lot of networking experience. I would leave it as is. If you do then fine, change the IP and subnet mask addresses to something of your choosing. I set mine to 6.#.##.1 for the routers IP address and 255.255.255.192 for the sub net. Also make sure that your Primary and 2ndary DNS server addresses are filled in on the Basic/Internet/Manual page. Sometimes they wont fill in. You can find this on the Status/Device Info/WAN section. Basically, keep things simple for your self. KISS! If it works then best to leave it unless you have the experience and knowledge to do more.

Once you get the setup going and everything connects, save off your config file so if you do go back in and make changes and good something up, you can reload ur saved file and it will set it back to the last known working state. Let us know how this goes.
