Query: difficult to install

After spending over 4 hours with tech support that does not speak English, it was determined the unit I bought was defective. Received another unit from Amazon. I also bought a Linksys router so that equipment would be the same hoping to simply installation. Still no luck. Followed the instructions manual to the letter and could not get the bridge to work. I refuse to call the tech support again.
