Something like this is where the people from Best Buy are probably worth having them come and set up. There are usually two different bands for wifi and one is better for streaming video than the other but it doesn't broadcast as far or as well so they could tell you. When I set ours up I at the time bought a top of the line router for the basement and later an extender for upstairs particularly for the frequency needed for streaming video. Seems to work well in our house. Have thought about upgrading the router as they seem to keep coming out with better ones.
I didn't know Best Buy did this. I might have to look into that. We just put our house in Urbandale on the market yesterday afternoon, and we bought a home in Ankeny. I'll have to get a new set up when we get there. Would be nice knowing someone who actually knew what they were doing was setting it up. Thanks for the advice.
