I have a problem with a B593s-22 router with firmware V200R001B270D25SP01C103. On this router DynDNS is not working. All necessary data were multiple entered, but it seems the IP address ist not transmitted to DynDNS. When I look in my DynDNS account, the IP address was not updated. It's strange because I have three more B593s-22 routers and they work properly, but the have firmware V200R001B236D30SP00C00. All routers have the same settings.
I tried already the following:
- factory reset
- new loading the firmware (I have the bin file)
Unfortunately I cannot load the firmware of the other routers on the router that is not working correct. It seems it is forbidden, since the upload fails.
Has anybody a solution?
