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

@SBBradford I use a AT&T router. I had trouble linking up to the extender then staying connected. Finally I used the WPS button and now it works perfect and stays connected.

@Carl Hi - any fix on this? Just bought tp-link via amazon - and same issue - I have Spectrum - and have the RAC2V1k router; they will NOT assign any other router - Spectrum is notorious for being difficult about changing routers - and like the other guy here, buying own router is a HUGE risk, rarely if ever works.
I called Spectrum. They gave suggestion to push "WPS" button on back of the router. Did nothing. :( And they punted to tp-link to figure it out..any solution? *other than the method you noted before, fyi - interface changed, so might need to redo screen shots on there - no longer a viable option....
So...fixed? or will just have to return tp-link....
I guess if you Spectrum/Time Warner internet - no go....?

asside from using your own modem/router no. We are still waiting for Specturm to resolve the issue with their vendor.

@Carl I found the solution with any WiFi extender
Configure your extender with static ip
same gateway than your spectrum router
same subnet mask
Use spectrum dns
209.18.47.61
209.18.47.62
and here comes the trick
(the static ip for your extender has to be out of the spectrum dhcp range, for example... if the dhcp range is 192.168.1.2 to 192.168.1.100... your static up has to be 192.168.1.102)
and that's it

No nothing yet. The issue is with Specturm but they have been quite slow to resolve. I will ask the team for an update and if one is available update this thread.
