I have security cameras that are stretched for wifi signal. I have one RE-220 already for in house and wanted to put another RE-220 nearer to garage to increase signal strength. I put the second one in and cannot get those 3 cameras to connect to the second RE-220 - hoping I don't have to reinstall cameras to select the second extender. I followed instructions and it set up perfectly. It connected to my main router and it has different ssid and great signal strength. I set it up with the same network name as the original as I was hoping my cameras would connect to the best wifi signal. What did I miss? First time using extenders and have read many internet articles how to use 2 extenders but can't get it to work.
