Hello @Malakiaso
Just a couple of thoughts here that may help. First, client devices decide which access point to connect to and when to switch between them. Google/Nest WiFi supports some specifications that can help clients make better decisions about that (802.11k and 802.11v if you are interested). But, not all client devices support those, and the ones that don't may not do a great job of deciding when to "hand off" from one access point to another. It sounds like the device you're using may fall into that category. If so, you may be able to force it to re-connect by briefly disabling and then re-enabling the WiFi on that device after you've moved closer to another access point.
Second, if your device is getting poor connectivity in your bedroom, then it's possible the Nest WiFi Point unit in that bedroom is also struggling to get a strong connection to the primary Nest WiFi Router in the living room. I would run a mesh test in the Google Home app and make sure that point is showing a "great" mesh connection for itself. If it's getting a poor connection, then you may need to think about changing the placement of the primary, that point, or both in order to get a better connection for it. Typically, recommended placement is to have the secondary point units no more than one or two rooms away from the primary so they can get a strong connection for themselves and provide coverage for more distant clients. But, that assumes the walls and floors (if the signal is going between levels) are constructed from typical hollow wall / timber framing. If the walls / floors are concrete, brick, or plaster, then secondary / point units will need to be much closer to the primary (and getting coverage to more distant clients will be much more challenging).
I hope some of this helps!
