The LeTV S50-2D version that was started years ago lives in a duplex house. The router is in the study room on the north side of the second floor. When I put the TV in the living room on the first floor, I found that the wireless signal was only one frame!
As an obsessive and hands-on machine friend, when you see LeTV's S50's wireless signal can not be fully satisfied, so I began my own long-term wireless signal enhancement transformation.
Start with the exchange of routes, from the JCG villa version to TP881N to Dlink Jin route, and then to Taiwan's ARG1211 GM5, TOTOling... to understand the routing of friends know that these router signals should be how? Bridge, increase the router antenna, change the position, relay ... I can not be satisfied with repeated attempts. Inadvertent Forum Box Forum A friend's post on the box plus an antenna caught me. In this regard, thanks to Zhaoy's shoes, the box can be transformed. Should the S50 be remodeled? So I began to collect the S50's disassemble drawing. I would like to thank my thanks for the support of the children's shoes at the digital home Tangjian. Links I do not have permission to upload, please yourself Baidu search! 
I'm ready to buy something when I buy it back. Here are the photos of the disassembled wireless module and the built-in antenna: 
After removing the wireless module and the back cover of the TV, I took the company to the company, because I saw the solder joints were more detailed and my welding level was a bit ambiguous, so I asked the workshop workers to help. 
I have read all kinds of information and I am ready to start. I first bought a SMA adapter from a certain treasure. This is very cheap. Within 2 yuan, the line is also 6-7 yuan. I didn't know the inside of TV. The structure bought two wired and two non-wired connectors, but later proved that my choice was correct, as I will mention later. 
Too busy, I used a line in the upper right corner, because the line is very long, I decided to install it in the upper right corner for better signal coverage, so this root I only welded the SMA head, did not use the line . And on the left, I directly let the workshop workers help to solder the wireless module. Because this line is short it is ready to be installed on the left.
Do a good job of wireless module, I will open the hole in the back of the shell, I found that the 1 o'clock and 11 o'clock direction in the case itself reserved two screw holes, but did not penetrate, is definitely the best position The following points do not prevent the internal structure of the machine. I used a drill and six drill bits to make a light effortlessly. The picture is a rendering of the SMA adapter after it was punched.
At night, go home and install the wireless module. Take the cable and fix it with the original tape. Tighten the SMA head and fix the 19 screws on the shell.
I installed two 6DBI antennas that were down when I modified the wireless router. At this moment, I was excited because I really didn't know how the effect would be! 
The signal is perfectly full 
The effect of expectation has been achieved.
Facts have proved that the addition of high-gain antennas will certainly increase the receiving effect of the LeS50. In particular, some children's shoes wireless routers are far away, or the signal attenuation caused by the need to pass through the wall is absolutely effective. In addition LeTV S50 is a good transformation, there is no technical difficulty. Things are cheap, this reconstruction costs a total of 8 yuan SMA first two + 6DBI antenna a treasure good also 10 yuan a bar because I was removed from the router so did not count the cost.
I think it's difficult
1: When you remove the back cover of the TV, remember a total of 19 screws, no more than a lot, in addition to the other two flat head size is the same! ! !
2: After removing the screws, only the bottom right corner of the sound button has a connection, is stuck with the buckle, not very tight, with a screwdriver to pick it up. Here do pay attention! ! !
3: Welding SMA connector with the line of non-professionals is best to find a professional hands-on, small solder wire fine. Take the wireless module down and take care of it. Because there is an integrated module on it, be careful not to touch the solder joint! ! !
4: Children's shoes hanging on the wall Please also pay attention, carefully measure the size and see if you can install the antenna behind.
5: It is also the most important one. There is no warranty after dismantling. Please remember to remember and remember! ! !
Well written so much, I hope to help children's shoes that would like to transform again, and ask professionals to correct me! Thank you~ 
A router adapted with five 9DBI antennas
All finished, thank you for your support of children's shoes! For children's shoes that like DIY, this method is suitable for televisions and boxes that are similar in structure to the S50. Seeking to start ~
