Suspecting a faulty Internet port or Ethernet cable has produced little if any results to mention. You are still facing the same router to modem connection problem. Separately, they both work fine. Therefore, you’re most likely looking for ways to cope up with this Linksys router-modem conflict. Follow the methods discussed below to successfully do that.

What can I do if my Linksys router is not working with a new modem?

My Linksys router is not working with the Spectrum modem

1. Reboot the modem, then the router

Rebooting your router means cycling the power to it. You should first try to unplug the power connector from the back of the router and plug it back in. Rebooting the modem, then the router, and finally the PC restores connectivity most of the time.

2. Clone the Mac address of your computer

Clone the MAC address of your laptop to the route. This should work, and you ought to be all set and ready to surf the Internet. You could also power off the Spectrum modem, unplug the coax, and wait a few minutes so that the modem loses the associated MAC address. Then, plug it back in and see if the connection works.

My Linksys router is not working with the Arris modem

1. Power cycle your router and the modem

There is a difference between resetting a router and rebooting a router. The first fix you should try is to reboot (power cycle) it. This procedure will hardly take a few minutes of your time, so power cycle both your router and the modem.

2. Change the router’s default IP

Most Arris modems use the default setting for their IP and that will conflict with your router’s DHCP. Try changing your router IP, then reconnect.

3. Reset the router

Everything else left now is pretty much returning to the factory defaults. Reset your Linksys router, then connect your modem to the router. From the router, connect a cable to your computer. If this doesn’t work, type cmd on your RUN menu (Windows). A black screen window will come up next. Type ipconfig/release, then ipconfig/renew. It should be working after that.

My Linksys router is not working with any Comcast modem

1. Power cycle the devices

Power cycle is just another way of saying that it’s time to turn both your router and Comcast modem off, then on. Rebooting them can often fix connection problems similar to yours, so give a try to this method.

2. Check ISP MTU requirements

Determining the correct MTU size to resolve intermittent wired connections is imperative. After knowing it, don’t hesitate to change the MTU Size.

3. Reset the Linksys router

First of all, ensure the port on your computer is enabled. If you turn on Wi-Fi, it disables the Ethernet port. Turn off the modem and do a factory reset on the router by taking a sharp object and pressing down on the Reset button for about 30 seconds. After that, unplug and re-plug the router’s power adapter. While it’s booting, plug in a straight cable from the PC to a LAN port on the router. Also, plug in a cat5e or cat6 from the router’s WAN port to the modem. Wait until the router finishes booting. If it doesn’t open a browser, then open one by yourself and enter 192.168.1.1 in the address bar. That should get you to log in and solve the issue. Remember, a reset like this one erases all settings you have ever changed in the past. Worried you must begin re-configuring these settings? Follow this handy guide for help on this important process. If this doesn’t work, we would recommend calling your cable ISP and telling them to send a tech who is able to set up the Internet through the router.
