I was looking for great PQ and didn't care about 3d, so snagged the 52" for under $1500 USD from one local retailer who was clearing them out.
About wireless: I also have the Asus RT-N16 running latest Tomato USB. Wi-fi works great, super reliable with all my laptops and desktops never drops connection. I have all devices on static IP addresses and configured the TV for static as well. It would connect fine and would show almost all the bars for reception but you can't watch a movie, from Crackle for example, without wireless completely losing internet connection at least once during the whole movie. My MacbookPro has no problems connecting from the same spot as the TV. I detect about 15 Wifi APs in the apartment so I thought it may be just the crowded 2.4Ghz band. The LX900 manual recommends a 5Ghz AP to use with TV and I wanted to get one anyway so I bought a Cisco E2000 router with selectable 2.4 or 5 Ghz bands.
I loaded the Cisco with Tomato as well and configured it as a 5 Ghz access point with the Asus as the router/gateway. The TV now connected on 5Ghz band to Cisco. That did improve things somewhat and the drops now aren't as frequent as were on 2.4Ghz (although I get worse reception/bars on 5Ghz) but its still too often. I can usually watch a movie on Crackle without losing internet but if it still drops out often enough. Laptops never have issues with both of these routers and get super stable reception, so 99.9% its not the routers.
Another trick that seems to work is if wifi loses connectivity from TV, go to network setting, turn wifi from ON to OFF, wait a few seconds and toggle it back to ON. Then check the connection in the network settings, that will normally re-establish wifi connection. This further proves its the TV problem.
This is a convoluted way of working around it and is not acceptable for such a high-performance TV.
I am sure that running an ethernet cable would solve everything but why advertise or have the wireless feature in the TV ? I'd rather not have it at all if its going to be working half-way or have it there but it should be fully functional.
Running cables thru apartment walls isnt' something I want to do so my next idea is to place the Cisco in the entertainment cabinet under the TV and run a CAT6 to TV's network port, then configure the 2 routers to be on same SSID (bridge mode?) and have the TV communicate thru wired port before Cisco transmits it to the Asus router. I am guessing this should solve the problem just as well as hardwiring everything.
If someone already tried this then let me know if this works well.
Besides wifi, TV pic quality is nice. I would definitely be even more upset about wifi if I paid anything near the msrp for it.
Radviewer: I too own the LX900 and I am able to operate with both wired and wireless (2.5ghz and 5ghz)--without the problems you describe. These are expensive TVs so I can certainly understand your frustration. I am sure you read my recommendations posted above so I wont repeat here.
***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 184.108.40.206 and the Secondary DNS to 220.127.116.11
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!
