Hey there. Sorry to hear about the connectivity issues. It can definitely be fustrating and hopefully the few recommednations here will help with your connectivity.
The first thing I'd do it "power cycle your Roku device for 30 secs.. don't need to wait longer than that
second I would restart your router like the other use mentioned is his response.
3rd I would perform a network connection reset on your Roku device. To do this step 1 go to settings, step 2 go into advance system settings, step 3 find network connection reset and lastly hit reset connection
.Once the network has been reset the roku willl restart. Go into setting and find set up your wireless network.
Hopefully this should solve the issue. I'd be surious to find out if you had any success and wish you the best of luck.
Oh i forgot one last thing. Lets say what I wrote above did not work I would recommend a manual factory reset. I'd recommend that be the last approach you should try though.
Write back to let us know how it goes!
