Hello, there is wi-fi router lb-link distributes wired (10mb) Internet access for phone and TV. But there are some problems, the TV signal is unstable if testing via speedtest, the TV shows 5mb/s, then 9, each time differently. Phone in place where a TV shows the best signal.
I read a little about the setting, always write in different ways, confused me tab basic settings wi-fi. Can you please suggest which mode (Network Mode) it is better to choose which Channel Bandwidth and different? I think I do something wrong chose here:

Thanks in advance :)
