Crapcast forced me to upgrade my modem (the old one was functioning just fine until they day they flipped the switch to OFF)

Now the PC (which is wired to the router) still gets great speed, but anything connected to the router through wifi moves from .3 to 1mbps

Yes I have restarted both, plugged in modem first, and then once it was 100% ready, then plugged in the router.


Disabled QoS on the wifi router. its a little better but now its 2mbps.
Any suggestions? I don't want to use Comcast's built in wifi unless I have to.

Check your "anything: device wireless adapter settings. I.e., no "auto" or "auto negotiate". Manually set to match the router.

Especially speed and duplex.

Or, if not auto, then try auto.

Focus on one device to get the settings to work if you can and then use those settings as a model/template for other devices.
