Optik TV wireless box signal lost

[wireless]

I just got Optik TV installed in my home. My wireless box shows full bars, box I noticed that channels tend to freeze and I get the signal lost message. Is this something that can be resolved through my third party router or a power line adapter? Or would this be another issue?
