Issues using a TP-Link Range Extender with Spectrum Internet services
Current as of 4/12/2019
Affected devices:
- TP-Link RE450 (all versions)
- TP-Link RE400 (all versions)
- TP-Link RE355 (all versions)
- TP-Link RE350K (all version)
- Spectrum Askey RAC2V1K
*Note: TP-Link at this time is not aware of any other affected models. However, if you feel you have a model that is affected please contact us at ussupportteam@tp-link.com so we can help research our model.
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
- Segemcom RAC2V1S
- Netgear 6300
- https://www.spectrum.net/support/internet/modems-routers-wireless-adapters/
- 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

I understand, i was simply offering possible solutions. What was determined was that this was a specific issue caused by the firmware of the rotuer which is out of our control and puts us at the mercy of Spectrum and their team releasing new firmware.

Thank you. What you described in your post above was the work around that they have come up with. We just enageged with the R and D team to confrim this. I do want to be clear that this is not a fix by any means, This is simply a work around to use that can resolve the issue unitl Spectrum updates the Firmware that is actually causing the problem.
For a more graphical representation this is what was explained to us:
- Disable the DHCP Server of the Spectrum router
- Set RE450 to static IP address in the same subnet of the router
- Enable the DHCPS of RE450 and change the gateway and DNS settings of DHCPS, the gateway and DNS MUST be router’s LAN IP address.
