No I've seen this too. Also on TSW panels. The TSR remotes have the shittiest wifi connectivity. Sometimes they latch onto other access points that were once connected. No matter what you do its almost impossible to get them to forget another WAP. Console commands for it dont work, init/restore doesnt work- it will still not forget an older WAP. Only way I could get them to forget is by the factory restore button pushing BS. I feel like those in those scenarios we have the biggest issue with them being unresponsive as you posted.??
