When you change from DSL to cable broadband, you just change the router, there are no software changes on your computer required (or on the router, your question is not clear). Now that you have your computer working directly on your cable modem you just need to record your computer's MAC address, and set that as the MAC address in your new cable router. Other than that, you shouldn't have any problems. I've done this a couple of times, and just walked through the web configuration pages for the new cable router, and it just works (assuming that you transfer MAC addresses). No software to change.
Hello, I previously had DSL with my own combo modem/wireless router. I cancelled DSL and got Cable broadband instead. I've already unplugged my DSL modem/router and have my cable modem hooked up, all is running well. I bought a new Netgear N600 wireless router that I want to set up. My question is....Do I have to uninstall any software or files from my previous DSL modem/router before installing my new cable router?
