There is definitely a step missing, or additional information that could be added to the instructions when changing channels. We had a heck of a time getting things straight with mine, Brad's, and Jim's to run on 3 channels.
1. Turn on access point, and target sensor hub
2. Pull up shotmarker (192.168.100.1) on your tablet/phone/computer
3. Wait for them to connect to each other and display a target
4. Tap the Globe/settings icon
5. Tap Switch Channel
6. Tap the channel number you want. I clicked #4
7. Tap the target you want to change. There should only be one target displaying unless there are multiple targets turned on when you are doing this. If there are, tap your sensor hub number. The number is on the back of the sensor hub. This step isn't exactly clear in the instructions. It says switch, but should state select or tap the targets/sensor hub you want to change ..
8. WAIT.. WAIT... Wait some more. (not sure if this part is needed, but it seemed to help.) Then Click Green Check Box
9. Access point will reboot. Then wifi will disconnect. When it comes back on, it will be named "Shotmarker4". This may take a few seconds.
10. Connect to Shotmarker4 wifi.
11. Wait some more.
12. Target and Access Point will eventually connect to each other, and you'll be ready to go. It could take a few seconds.
