I just switch between ATT Uvers to Comcast. The comcast router is both a 2.4 and 5GH. I have tried many times to connect my Gen 1 unit to the 2.4 connection but it will not connect. I still have the ATT router and can connect to it. I intend to buy a router for the Comcast but don’t want to get one that will not work with the Gen 1. Want to cancel my ATT account as soon as possible but can’t until I get a new router that works. Any Ideas?
@nelson675 - do you have the same SSID (network name) for both the 2.4 GHz and the 5 GHz networks? If so, I’d try different names on each band.
Which router are you using with Comcast? Does it have a firewall that is blocking some outbound ports that Rachio needs?
How strong is the new Comcast based WiFi signal at the Rachio?

I would recommend you schedule a call with one of our networking specialists, and they should be able to get you resolved more quickly!

Thanks for responding. I do have different network names. The signal is strong. It is set at minimum security for the firewall. I’m going to schedule a call with network specialist and see if they can help.
Hey @nelson675-
I gave the link to this thread to our support team so they will be a step ahead! Looking forward to getting you connected!

Thanks for all your help. I found the problem and am now connected. I know I have a support team call set up for Thursday at 12:00 but no longer need it. Don’t know how to cancel it can you do that for me?
Just so you know the problem was I was putting in the wrong Password. I forgot I had changed it so the one on the side of the router did not work. No issues with your device. PS very happy with it…

@nelson675 - that’ll do it 9 out of 10 times. Thanks for describing what the solution was.
I bet @mckynzee can cancel the support call for you.
