Hello, Please let me know that how to fix Linksys router is not working with a new modem. I am facing some issue in this. Help me.

Fix Linksys Rrouter is Not Working with a New Modem:

Every router becomes dysfunctional at certain times due to firmware updates or incorrect drivers. So, are these Linksys routers. Yes, one of the common problems that occur is that the Linksys router is not working with a new modem. It goes pretty annoying when your router stops working with a new modem. This problem either occurs from the very beginning or unexpectedly loses the connectivity with time. 

But as you suspect a faulty Internet port or Ethernet cable, you notice that your Linksys router is not working with a new modem. Though separately, both of the hardware works fine. Therefore, you are likely looking for ways to cope up with this Linksys router-modem conflict. Using the methods discussed below, you can successfully resolve that.

What to do when Linksys router is not working with a new modem?

When your Linksys router is not working with a new modem, simply perform the given instructions:

1. Reboot your modem and the router

This is the initial step you need to perform when your router is unable to work with another modem. By rebooting your router, you mean cycling the power to it. For this, you must first unplug the power connector from the back of the router and plug it back again. So, reboot the modem, then the router, and finally the PC restores the connectivity most of the cases.

2. Clone the Mac address of your computer

Step 1: Firstly, launch any installed web browser on your system.

Step 2: Next, type and enter the default IP address of the router as in the address bar.

Step 3: Now, type and enter the login details for your router. Usually, the default username is admin and the password is blank.

Step 4: Click on the OK button.

Step 5: Under the Setup tab, click on the sub-heading called MAC Address Clone.

Step 6: Here, click on the Enable option.

Step 7: Next, click on the Clone Your PC’s MAC option.

Step 8: Lastly, click on the Save Settings option.

Step 9: Now, clone the MAC address of your laptop to the route. This should probably work well, you must be all set and ready to surf the Internet.

Optionally, you can also power off the Spectrum modem, unplug the coax, and wait for the next few minutes so that the modem loses the associated MAC address. Thereafter, plug it back again and check if the router connection works well. 

What if Your Linksys Router is not Working with the Arris Modem?

If Linksys router is giving incompatibility with Arris modem, then follow the given set of actions:

1. Power cycle the router and modem

Step 1: In the first step, unplug both the modem and the router.

Step 2: Wait for the next 30 seconds that allows the short-term memory of the devices to clear completely.

Step 3: Now, plug in the Arris modem back again.

Step 4: Again, wait for few more seconds and let modem connect before turning on the router.

Note: There is a fine difference between resetting a router and rebooting a router. The first fix suggests you reboot (power cycle) it. Since the process takes a few minutes of your time, so it is recommended to power cycle both your router and the modem.

2. Modify the default IP of the router

Step 1: Quickly access your Linksys cloud account.

Step 2: Under the Connectivity tab, click on the Local Network option.

Step 3: Click Edit button next to Router Details.

Step 4: Now, enter the IP address for your router.

Note: The IP address for your Linksys router can be:

  • to
  • to
  • to

Most of the Arris modems make use of the default setting for their IP but that conflicts with your router’s DHCP. So, try changing your router IP first and then reconnect.

3. Reset the router

The last option if your Linksys router is not working with a new modem is to simply reset the router. This means that you can return to the factory defaults. So, reset your Linksys router and then connect your modem to the router. Through the router, you can connect a cable to your computer.

If that doesn't work well then type cmd on your RUN menu (Windows). A black screen window is then displayed next. Then, type ipconfig/release followed with ipconfig/renew. There is a possibility that you are unable to access the Command Prompt as an admin.

Hope this article works when your Linksys router is not working with a new modem.
