I have a Linkstation Live HS-DHGLB20 (1TB) on a wired Ethernet network (1Gb speed). I have today upgraded my fw from 2.10_0.05 to 2.11_1.01 beta. I am accessing my files from a PS3 with fw Version 2.6. Before my Linkstation fw upgrade access to my files from the PS3 was OK but is now irratic giving acces to only some picture files and no music or video files. I also keep getting the "DLNA protocol error (2101)". Further all my Linkstation files ARE accessable from the PS3 if I use a software DNLA server runnign on my PC so it does seem that the Linkstation firmware upgrade has caused the DLNA problem. I have tried to reverse the fw upgrade by downloading "hs-dhgl_2.10_005.zip" but running the " LSUpdater.exe" file from this fails to find my Linkstation. Please advise on how I can either fix the beta fw upgrade or reverse the upgrade. Thanks.
