Symptoms:  The range extender will connect to the router, devices will connect to the RE, and they will be assigned a correct IP address (192.168.x.x) however, they will not be able to access the internet or communicate with the gateway address of the Spectrum router.

 

Cause:  Internal testing has revealed the cause is the current firmware in the Spectrum router (version 1.1.16)

 

Possible Solutions:  Currently we are working with Spectrum to fix the issue.  In the mean time we suggest one of the following solutions:

  • Request Spectrum to downgrade your router’s firmware to the previous version (1.0.16)
  • Request a replacement router from Spectrum.  We have confirmed the following models are not affected
  • Assign IP address to your client device manually (Static IP) *consult your device manual
  • Make the range extender your DHCP server (See Below)

 

Making your Range Extender your network’s DHCP Server:

Step 1:  Disable the DHCP Server of your Spectrum router

Step 2:  Seth the RE450 to a static IP address with in the router’s subnet

Step 3:  Enable DHCP Server on the RE450

Step 4:  Change the Gateway and DNS settings.  Both the Gateway and DNS servers must be the Router’s IP address. Example:  192.168.1.1
