Unfortunately I can't assist with router configurations. There aren't any ports I suggest opening, and would have to refer you to your router's troubleshooting. Opening ports isn't recommended for security purposes, and there may be a different option or setting that would allow the player to connect to stream content.
Yes, there a lot of postings on connectivity issues, but mine seem to defy everything that has been posted, so here it goes:
-IP is Comcast; I have a Motorola Docsis 3.0 modem
-Cisco WRT110 (Linksys) Router; upgraded to latest firmware
-Bluray right away could connect to the network; during the network test, it got to ping the gateway (3rd step), then came back with the "HTTP port is blocked by something like an internal firewall program..." message
-I opened ports 80, 8080 and 443 (per some suggestions on the boards) to the IP address assigned to the Bluray
THIS WORKED....had netflix, etc. I upgraded the Bluray firmware like it wanted me to, which went smoothly. This worked fine for roughly a week or so. Then, out of the blue, went to access Youtube tonight....no internet connectivity....same error as before. Absolutely nothing changed in my network during this period. (Wireless connectivity to internet via laptop is fine)
Linksys only lists two ports, 80 (http) and 443 (https), realted to "HTTP", as this error is telling me. Is this just a generic error that's sending me down the wrong path? I'm at my wits end....are there other ports I need to open to the bluray? Something else I'm missing?
