No response after changing my router

[cgrylmz]

Hey,
I've been using my sonoff devices for a couple of years. Recently i've changed my router. But i've set the SSID name and password same as before in order not to have any connection issues. Unfortunately i'm having connection issues. On home kit, sonoff devices with HAA don't respond.
My sonnof devices which have firmware 10.8.3 has no problem, but the devices that have firmware 10.7.1 is having this issue.
Is there any way you can suggest me to troubleshoot? And is there any way to update SSID info in the devices where i can change wifi password/name without connecting them to usb on my computer?
Best.
