|I am having problems getting my network to work and am going crazy trying to fix it. Can someone maybe help me out? |
My setup is as following:
I've got a Cisco 2425 Eurodocsis Cable Router [CABLE ROUTER], provided by my ISP (UPC in the Netherlands) and it's connected to the main cable splitter (provided by UPC) and serving 192.168.1.x addresses.
Downstream is a Cisco E4200 Wireless Router [PERSONAL ROUTER] (w. 4 port switch) serving 192.168.0.x adresses.
The problem is when I connect my client to the [PERSONAL ROUTER] it gets a 192.168.100.x adress (!!!!).
If I browse to the gateway 192.168.100.1 I get the following pages...
It obviously is some device belonging to my cable provider UPC since it has a lot of "analogue signal metrics" stuff on it. It definately is not someting in my house, as said the main TV cable "splitted" output goes into my CABLE ROUTER, no other devices in my house.
Needless to say the cable provider helpdesk guy (after waiting an hour to get through to the call centre) told me to disconnect my router for 1 minute (of course they won't wait for reboot) and then call back...when I did they allowed me to send them a mail, which hasn't been answered to date
So my question is: anybody got a clue as to what's going on? Why don't the CABLE and PERSONAL ROUTER not respond to the DHCP lease request and some upstream device does? Is it a timing thing? Could I block the DHCP request from going upstream? So beyond my subnet? An wHy would this Thompson thing be serving DHCP to begin with?
I am able to connect to the Internet if I connect to the Cable Router directly and using DHCP. I've also been able to connect to the internet via my PERSONAL router, using static ip adresses, but this is only temporary, after a while the connection goes down.
Any help is greatly appreciated!!
