From my experience, if you want a computer to run consistently you need clean power. If you have many computers, all communicating with each other, and you are trusting them with such a critical task as the flight controller on a uav, you need extremely clean power.
It may be possible with enough ferrite and tantalum to get some solos to be reliable most of the time. Adding the second battery wasn't a big deal, I just cut and soldered a few wires. The whole mod took about 30 minutes. You could probably spend countless hours chasing your tail to find what part is susceptible to what noise under what conditions. Or you could run the sensitive electronics on clean power and have fun flying a reliable drone.
All we need to do is identify a source for an appropriate ferrite bead, and people are off to the races with a potentially useful and easy mod to help people with a crappy stock GPS.
The stock GPS is indeed crappy. It has multiple design flaws that 3DR was fully aware of. The engineers didn't want to use it. But 3DR's management didn't want to spend the money on a properly designed one.
That you're experiencing the same WiFi problems on the second solo is perplexing. This happens regardless of location? WiFi congestion can ruin your day, and if you're always flying in an area with heavy wifi congestion, that is what I would normally suggest. Are you test flying the modified solo in the same location you previously have problems with it dropping out?
On the second one, if it doesn't reconnect until rebooting the controller, wouldn't that indicate a problem with the controller, not the solo? Possibly a heat related malfunction? In such a case, I'm not sure how noise filtering on the solo would mitigate that. I can see the noise filtering helping with the crappy GPS. But the WiFi doesn't make sense if the solution otherwise if to reboot the controller.
Ah, so this hasn't been flight tested yet to see if the connection issue improves. I must have missed that.
Just remember that the Solo's that are provided as a replacement when yours "goes sideways" are all "refurbished" in other words ones sent back for a fault or some other problem that 3DR has "fixed".
Please, keep me posted on flight times, as a Creator handling isn't a big deal because I need to fly slow & smooth to get great shots. However flight time is super important.....2hrs even 45 mins is a big-time Super modification.I like the idea of a failsafe reverting to the main pack. The only reason for the second battery in the first place is to give clean power to the critical components, not to increase the flight time. However with the 6 amp hour I have gotten well over 12 hours of run time with the gopro and gimbal during non flight tests. So I am thinking the 1 amp hour would last at least 2 hours in flight, far surpassing the main battery by about 10 times.
I think you're confused. That was 2hrs and 45 minutes sitting on the ground without the motors running.Please, keep me posted on flight times, as a Creator handling isn't a big deal because I need to fly slow & smooth to get great shots.

Please keep me posted, thanks.

I'm good with the idea, but where did u isolate the compr. parts from the motors?
Sorry for any confusion P2P, I will try and explain what I have tested and what results I have attained.
ORIGINAL SINGLE BATTERY ARRANGEMENT:
While the solo is on the ground and the motors are not activated the controller works perfectly, no errors, with live streaming gopro video, for literally hours on end, both at short and long range. I have not seen a single error from the controller or gopro or the gps while the motors are not powered. This is with over 10 total hours of non flight testing on the original battery configuration.
While in flight the gps and controller connection randomly cut out every 10 minutes or so. Independent of range or interference/obstacles. This is with about 5 hours of flight testing with the original battery configuration, mostly on tether.
what sort of tether ?
