................. However, I'm a little reluctant to change the wireless channels for fear of causing havoc with my wife's (work) PC connection.
I think I would be reluctant to make changes to the router myself. With my router and cable broadband connection, making a significant change can cause the network to assign a new IP address to the modem. I don't know your wife's use, or if DSL ever reassigns IP addresses, or
even if you have a static IP now. But
I do have a good working knowledge of WAF... and I understand that any error here would be critical.I would commit to leave the router on so as to get the email notification. I then would turn my attention to the camera setup itself to correct the "interference and image distortion".
Of course my first thought would be to replace the driveway camera with a wired camera, or
convert it to wired. Of course sometimes wired can be really difficult to install in some areas. Maybe finding a new location to get a similar camera view with a wired camera may help. Or staying wireless and getting the [another] receiver located closer to the driveway camera might reduce the router interference.
Lastly... replacing that one camera with a wireless camera that uses another frequenty,
like 900mhz, could help.
