Then I fully restarted everything. The TV was absolutely "blind". Nothing fixed. Users who read the forum frequently may know that I have other issues on Gargoyle and Lantis said viewtopic.php?f=12&t=11180&p=47844#p47850 that the firewall stucks sometimes and cause a few glitches like irrelevant PPPoE uptime. I dunno how this can be related but checked the uptime and saw that Gargoyle is continuoed counting from 9 days. I dunno too much about the Gargoyle firewall but if it stuck... it's stucks a lot for me and I'm sure that this is not normal. So I decided to reset the web usage history and voilà. The TV see the content again.
My PCs see the media server via network but after a short time they go blind. Only restars help but this just a temporary fix.
Another strange thing that I had ~2MB free space in ROM and now I have only 120kB while I did not installed anything meanwhile. How can I check what eat that freespace?
The reason why I not opened several threads are the chance that these things somehow related and the overall forum experience. Only a few members active here and I already have a bunch of questions/bugs without answers/solutions.
So what the hell?
