It's got NOTHING to do with WIFI.
I am not sure about this. Last Friday we had a short break (approx. 5 sec.) in the WiFi-Accesspoint. After that we could not control the volume of the Soundbar anymore. Pressing the volume knop on the Panasonic Remote did not show any reaction on the Bose Soundbar 700. We had to restart both systems.
Before the firmware update 4.0.8 (!) we had definetively no ARC/CEC issues at all. Our other (kitchen) system - Panasonic-TV and Soundbar 500 - is working without any of these issues until today.
I too am having random cut outs with the sb700 HDMI arc connected to my LG C8 OLED . I tried all the suggested steps to fix it and it seems like it works for a little while but eventually returns to cutting out. I also tried the optical cable that seemed to lack in quality compared to HDMI but it too cut out but not as frequent. Wondering if this is something that can be fixed through a update or should I be looking into returning my system.
Bose is just avoiding this problem everyone is having with their sound bars disconnecting causing the sound and in our case, the picture to drop! Our sound system worked fine until the latest firmware update. And yes, we have tried every suggestion you have posted to try and fix the problem! If Bose can’t fix this problem immediately, we will be returning our sound bar 700 and our home theater speakers. I would never recommend Bose to anyone again!
PS: I have a video of the problem, but your website won’t support the video. If someone in customer service would provide me their email address, I can forward the video to you.
