Roku TV keeps disconnecting from wifi when i turn it off and back on

SO... This jusr barely started happening last week. So ill explain,

i have a HiSense Roku TV 40" and when i turn my tv off. leave somewhere and come back i turn it on and its not connected to the wifi i have to restart my tv from settings or i usually clear the CACHE by pressing 

"Home" 5x

Then Up button 1x

Then Rewind 2 x

then Fast Forward button 2x

and it works but then i turn my tv off and leave then come back and i have to do the process over again. i have restarted my wifi router as well. and it didnt change this. I also updated my roku tv a few weeks ago, not sure if that is a bug that roku hasn't fixed but just wanted to throw that in there as well. And will having a MONSTER LED light Bar interfere with my connection? cause my roku remote changes the light colors on my monster light bars. lol i just wanted to add that just in case its the light bars that are interfering with the connection. if anyone has any suggestions please let me know THANKS.
