For years I have been connecting broadband on my 722K to the a Buffalo N300 router with DD-WRT software which is connected wireless to another Buffalo N300 router which is connected to a Time Warner cable modem. Anyhow, everything seems to work flawlessly until the latest L796 firmware update. The 722k still indicates that broadband is online and Diagnostics can send status and receive a confirmation code. However, when I try to explore TV shows , movies etc on the 722k using rhe Broadband I get a Unable to connect to the network server error 145 message. Has anyone seen anything similar?
