I used to have a Technicolor TG582N router, on my Windows PC I could watch videos stored on my Panasonic video recorder and on my TV I could watch videos stored on my PC. Then the router died and PlusNet sent me a 2704N router. Media streaming is still enabled in Windows on the PC, the videos are still in the same place, the video recorder still has the same videos, both the TV and video recorder can connect to the internet (via the router obviously) but...
the PC can no longer see the video recorder (I use VLC, on clicking uPNP the circle goes round and comes up with nothing. The TV can no longer see videos on the PC (I can browse folders beneath "VIDEOS" on the PC but it shows them all as being empty). uPNP is enabled on the router.
Any ideas? PlusNet just say that DLNA is not supported, maybe they've specifically disabled it in the 2704N?
