I have been using an old WBR-1310 for years and it's been reliable so there's no reason to upgrade. I recently created a hostname with DynDNS which allows me to access the router remotely. Do I need to download and install a software update client or does the router perform this function automatically? I have read that most newer routers perform this automatically without the need of a software update client, but due to the age of this router, I wasn't sure.
