My situation is this, I've been tasked with expanding our wifi network here at the shop. The building is about 300 feet long and 30 feet deep. The the main router reaches about 3\4 of the shop and then abruptly drops signal after bay 4. A cat5 cable was ran from main router to the office between bays 5 and 6 with a router added on that end. It works properly as a 2nd AP. Problem is the devices don't swap between the two networks. How can I facilitate the swapping of APs or have just one access point for the whole shop? Preferably one AP. I've looked into extenders, boosters, and repeaters. It seems like they all make a 2nd AP. This network will also be used for VoIP eventaully. Any advice would be helpful.
