Since you have Xfinity and also a 2.4-ghz only device, go into your router's Wireless Settings and verify/change the Wireless Mode is set to b/g/n.
Cable ISP routers (Xfinity/Comcast. Cox, and AT&T) have issued firmware updates to some of their routers starting last year that are causing connection and reconnection issues with some 2.4ghz wireless devices like Roku.
Your 2710 is definitely getting up there in age. The newer Roku devices are all dual-band (2.4ghz and 5 ghz capable) and of course, newer hardware. If the 2710 still suits your needs, try the b/g/n fix and see if that resolves your issue. (You can make these changes through the xFi app. https://www.xfinity.com/support/articles/change-wifi-mode-admin-tool-xfinity-xfi
Some routers won't let you change the mode via the app, so will have to contact Xfinity to make the change for you if you receive such a message.
I tried all that and still disconnected so I upgraded to a 4k and haven’t had a problem since. We shouldn’t have to replace our Roku’s every two years
