***However, If you are sure your TV has the latest firmware then you might want to try setting the DNS address on the LX900 TV wireless network setting. Set the Primary DNS to 220.127.116.11 and the Secondary DNS to 18.104.22.168
Other items to check:
Is your own network secured? ( If not, your neighbors may be using your bandwidth) Security setting on your router--Authentication Method: "WPA2-Personal" and WPA Encryption "AES" is optimal.
Is your router firmware updated to the latest firmware?
How much bandwidth did you purchase with your internet service? To stream video you need a good strong signal and plenty of bandwidth ( some recommend at least 3Mbps to 5Mbps --better 8Mbps + for HD).
Try disconnecting your other internet devices when you stream video to your TV.
Check to see if you can set video streaming as a priority on your router administration software normally called "QoS" function.
Distance from router: The 5Ghz signal has a much shorter broadcast range than 2.4GHz. So if your TV is relatively close to the router then use 5Ghz--if not stick with the 2.4ghz.
Note: I personally switched from the new Cisco 4200 Maximum Performance Dual-Band N Router to the ASUS RT-N56U Dual Band Wireless-N Gigabit Router because I found the ASUS produced a more consistent wireless signal while streaming video in my home environment.
I hope these tips help!
Thanks for those suggestions but I've used google dns settings from the start. Although not ultimate pro but I'm also not a network noob and have tried various network settings, changing gateways, routing differently, etc. and wireless just isn't stable with just this TV. And ofcourse, wireless is VERY protected so there's super slim chance anyone is stealing the signal.
. I've always had fw auto update setup and currently my fw ver is PKG4.107AAD.
Bandwidth isn't an issue. My isp speeds are comcast 15/5 Mbps for down/up.
As mentioned, my macbook pro and other computers pretty much never drop wireless signals, from either tv or other locations in the apt. Both routers are wireless-N. On 2.4Ghz router I get about 50-70mbps between router and laptop, measured from around tv location and with 5Ghz router I get about 108-150mbps. These speeds are WAY more than adequate for HD streaming. I can stream wirelessly an HD movie from NAS to laptop without problems anywhere in the apt. As mentioned before, tv is routed to 5Ghz router first since the 2.4G router dropped connections all the time to the TV, and then its connected to the 2.4ghz thru switch by wire. The 5Gig router still drops connections. The main issue is not even in frequency of drops but severity of them. Usually the only way to recover is to manually turn wireless OFF for few minutes and then toggle it back ON to reset it. Sometimes restarting TV helps. Once or twice it completely lost all the manual ip configuration settings, like it just reset to its factory default. Few times it just doesn't find any APs, although I have about 15 of them detected by a laptop.
I haven't had much time to play with Qos settings in tomato but I'm 99.9% certain that will not solve anything due to the way dropouts happen. When tv is using wireless there's no one else using internet so bandwidth sharing shouldn't be an issue.
Since laptops are super stable on wireless, so far it seems completely related to TV, perhaps flaky firmware or the wireless chipset this tv uses, etc. Still hoping to find a solution to this annoying problem besides running wires.
