NC450 V2 - If you have Wi-Fi connectivity issues please read
Model : NC450
Hardware Version : V2
Firmware Version : 1.1.6
ISP :
I have confirmed after testing on 2 different NC450 V2 cameras that there is are Wi-Fi connectivity issues with this camera depending on firmware level.
1. If you have firmware level 1.1.1 don't upgrade to 1.1.2 or 1.1.6. I found that the camera does work most of the time on this firmware level on Wi-Fi. It's not perfect as it still does drop or freeze the network connection on occasion. The higher firmware levels seems very sensitive to the Wi-Fi signal strength level. I found that you need at lease 85% or more signal for the camera not to drop the connection and freeze. The dropped connection is so bad that you can't even ping the camera.
2. If you can use the wired Ethernet connection on the camera it is the most stable setup without any issues. Obviously it isn't a convenient setup to run wires around.
3. Set the channel of your Wi-Fi access point (or router) to a static channel and not use the "Auto" setting. I found channel 2 gave me the strongest signal but it might be different with your network.
4. Set the router Channel Width from Auto to either 20 Mhz or 40 Mhz. I found 40 Mhz was the most stable for me. Changing this setting did drop my signal strength about 5% but the signal is much more stable and less vulnerable to interference.
5. You router might have a setting change the transmit power from low - medium - high. Set it to the higher level if required.
6. Position your camera to get the strongest signal. Even moving it a few inches can change the signal strength 3-5%.
7. If your router/access point has external antennas reposition the angles on them to maximize the signal. 3-5% increase can be found
8. If you have a longer Wi-Fi antenna available use it to replace the original one on the camera with it. Most Wi-Fi antennas come with a standardize connector.
After I discovered setting Channel Width to 40 Mhz my camera was much more stable and I can leave it on a live video on without as much freezing. The connection drops still happen but much less often and recovering the connection is actually possible now.
Hopefully someone from TP-Link will look into this issue and possibly fix it with another firmware update. Unless that the problem is actually with the hardware Wi-Fi card on the camera. Requiring the minimal Wi-Fi signal to be over 80-85% shouldn't be required for proper operation or drop the network signal so easily. I've used IP cameras from many different vendors and they don't have any connectivity issues because of low signal strength.
