Wireless connection is horrible!

I've owned for about 6 mos and suddenly have lost hdmi connection

I've never had a problem with the Wifi unless theres a bad storm disrupting the connection in general

Everything loads slow and the build in WiFi doesn't seem to pick up any strong connections

Tried several (4) of these, because we thought we were getting defective products, but every single one of them loses streaming connection mid-show as well as the BluRay and/or DVD 'jumps' from viewable screen to a green or blue screen or would simply be uber pixelated mid-movie, sometimes it stops all together and give us a green or black screen.
