Scenarios I have tried:
Using Canon Transmitter ST-E3-RT as the master and (2) 600 EX II-RTs as slaves.
Using A 600EX as master and B 600EX as slave.
Using B 600EX as master and A 600EX as slave.
I get the same result of the slave dropping link. The time varies. Sometimes it drops link in 4 mins, sometimes 10mins, sometimes 20 or more minutes. The only way to relink them is by turning everything off and back on.
All channels are the same. Yes, I have scanned for the best connection as well as every other channel and AUTO.
All IDs are the same.
Not near a wifi-router or airport, I'm in a row home in Philadelphia.
Using NiMh rechargeables and using freshly charged batteries for every test. Batteries are about 2 years old.
I have spoken to 2 Canon service reps and neither of them has any idea what the problem is. I really don't have the money to spend on sending everything in for "repair".
Any help is greatly appreciated, thanks!
Solved! Go to Solution.

Sadly I couldn't resolve the issue and Canon insisted they couldn't find a problem. I ended up buying new flashes - not an ideal outcome!

A firmware issue with the Canon or other flashes mentioned here? Did it resolve the issue for you? Do you have a link you can share? Thanks!

A firmware issue with the Godox receiver and transceiver not connecting to the R5 or R6; it appears to have been resolved according to comments. I am waiting for them to arrive to test but here's a link: https://www.amazon.com/Wireless-Controller-Receiver-Compatible-Smartphone/dp/B07W1JG2GC/ref=sr_1_22_...

No! The problem doesn't resolve. Canon, Where are you?

Yes!

I updated the firmware on both of my flashes and had the same issue after I did.

What flashes worked for you eventually?

This shouldn't be marked "solved." It might give Canon the wrong idea.

So I have come to the conclusion that it is something inside of my house that is causing interference with the trigger. If I take the setup to a park or my job then they work great will stay linked until the battery dies but but at my house it only last 5 minutes before the connection is lost. I have tried to narrow it down to find out what the culprit is but I cannot. For now I am using Godox X2 trigger and receivers. With the 600 speedlites it works flawlessly but the Godox receiver on the EL-1 speedlite it is a dumb trigger so You cannot change settings from the transmitter but it will fire if you set them manually. I encourage others to try shooting in a park or secluded location to see if it yields the same results
