Overall steps to take:
1. Have separate 2.4Ghz and 5Ghz SSIDs always
2. Ensure the exact same encryption is used on both devices, a lot of these boosters only have WPA/WPA2 Mixed mode, whereas most ISP supplied routers are WPA2 only out of the box. They need to be exactly the same.
3. Use different channels on the booster and the main router. Use either 1, 6 or 11, do not use the others. E.g. set the main AP to channel 1, the booster to channel 11.
4. On a windows device, if you have an Intel Card in device manager find your wireless card, go into properties, find "roaming aggressiveness" and turn this to the maximum value (this fixes most windows issues).
5. On 2.4Ghz ensure the booster is set to 20Mhz only and likewise ensure the main AP is set to 20Mhz only, there is not enough frequency if both are on 40Mhz at 2.4Ghz. Ensure one is not on 40Mhz and the other on 20Mhz as this will cause issues.
6. Ensure the same technology is used by the AP and the repeater. E.g. if the main AP is wireless N, do not have a wireless G repeater.
