Let me clarify as to what I have:
One desktop PC, running Windows 7 x64, with the E3000 connected to it via Ethernet connection. Within my PC, I have created a Shared Folder (C:\\TRANSFER), in which I have photos, avi, mp3 files. About 50 feet away, I have my Sony HD TV, to which there is WDTV HD Live connected, via the HDMI. I have attached a Linksys WUSB600N Adapter into the WDTV HD Live's USB port, so that I can wirelessly connect back to my PC, access the Shared Folder and play anything from there directly onto my PC. There is nothing connected to the E3000 via the USB port.
When I try this with the E3000 router connected, I have no problems accessing the internet from within the WDTV HD Live because I can go to Video / Youtube and play (stream) any videos on my TV -- as this is coming from the internet connection. However, when I go to Video / Network Shares - I see an icon for the E3000 router (called Cisco07519), and when I try clicking on it (with the idea that it would then show me the Shared Folder) , I get the following error “This network share cannot be accessed”. And that's as far as I can get.
Now, using the exactt same setup, without changing anything except "swapping" the routers, from E3000 back to WRT300N, when I click on Video / Network Shares - Without even seeing any router names, I am automatically shown the C: drive volume name (MYSTYKIY and when I click on it, I am immediately taken to the \\TRANSFER directory and can see all files there and of course they all play.
So somehow, WDTV HD Live is not getting access past the E3000 so it can then allow access to my desktop PC. And it seems that WDTV HD Live tech support folks are correct. Since this baby plays fine with WRT300N, but not with the E3000, it must be a Linksys issue.
I have tried disabling any and all built-in firewalls in the E3000, thinking that somehow that is the issue, but the result is the same. The new updated firmware, about which I wrote a couple of days ago, does not change my situation in any way.
I hope I have explained this as clear as I can.
