Hi I recently updated the software to 5.30 version, and after that I noticed a weird problem with video streaming, in general issue with internet bandwidth. Usually my b/w is ~35 mbps so that is sufficient for 4k streaming on youtube or netflix. The issue is after running for 10-15 mins if I pause the video or go backward the network speed is thrashing badly. For example when I check internet connection on netflix it shows ~30-35 mbps, but whne that problem occurs and I check the speed again I see the speed is dropped to <1mbps. Same with youtube, it can't load 4k videos anymore as the speed is ~1mbps. I can realize the problem as the thumbnails load very slow with scrolling. This problem does not get away unless I restart the TV or disconnect from wifi AP and connect back. The router always works fine I mean when I observe the problem on tv I can run videos on mobile seamlessly and see a speed of ~40 mbps on the same router. The router is kept next to the TV so I don't think it is some issue with wifi distance etc. I don't know what to do. I tried resetting but it removed all my app but it was actually not a so called "factory reset". So software version remained same. To rule out hardware problem I want to revert to previous version of the software but apparently I can't downgrade the software. Is there any other approach to load some previous version firmware?
