In addition to disabling “Airtime Fairness” which was stickied at the top, here are my RT-AC86U router settings which focuses on 2.4GHz band for Wyze cameras and my smart light switches. These are settings just what I used mainly for my environment and I found them to be quite stable.
Wireless - General 2.4GHz band
- Wireless Mode - Auto (you can set it as N/AC mixed, but I have 1 really old wireless G printer. Also I disabled 11b because I don’t have any of those devices)
- Channel bandwidth - 20 MHz (for better range and wall penetration)
- Control Channel - 1, 6 or 11 (you can pick which ever has the least interference)
- Protected Management Frames - Disable
Wireless - Professional 2.4GHz band
- Roaming Assistant - Disable
- Enable IGMP Snooping - Disable
- Multicast Rate (Mbps) - OFDM 6
- Preamble Type - Short (Long could be better for some IoT devices, but Short seems to allow me to connect quicker to Wyze cameras)
- Enable TX Bursting - Disable
- DTIM interval - 1
- Beacon interval - 100
- Enable WMM APSD - Disable (you can enable this for power saving, but from my testing I seem to get a better connection quality with it disabled)
- Modulation Scheme - Up to MCS 7 (802.11n)
- Airtime Fairness - Disable
- Multi-User MIMO - Disable
- Explicit Beamforming - Disable
- Universal Beamforming - Disable
- Tx power adjustment - Performance
In most cases, Wyze wired cameras needs to first establish an internet connection with a NTP server to provide the proper timestamp and record into the correct folders. Wyze’s app relies the recordings being in the correct folder to align the footage chronologically. If it can’t establish an internet connection to a NTP server, then it will start recording into a dated folder based on the firmware build date with its corresponding wrong timestamp. Your only choice will be then to physically remove the micro SD to view the footage in a PC or phone.
Cam V3 / V3 Pro / Cam Pan V2 with firmware 4.xx.13.0416 or newer will automatically restart itself after 30 minutes of internet outage (not power cycled). As there is no internet to connect to a NTP server to sync the correct time, it will start recording into dated folder based on firmware build date with an incorrect timestamp. Flashing that firmware will cause it to act exactly like the Cam OG cameras.
In comparison, the older firmware of 4.xx.11.8391 can playback without any problem (under the same condition) as it doesn’t restart itself. Although it will still record properly after 30 min of internet outage, if you power cycle them (without internet) then the recordings start saving in a dated folder based on firmware build date with a incorrect timestamp (this is is expected behaviour).
To work around this issue, you can enable local NTP server and intercept NTP client requests on your Asus router in Advanced Settings > Administration > System > under Basic Config. Set your timezone and your choice of NTP server link (ex. pool.ntp.org).
This will allow your Wyze cameras to establish and sync timestamps with your router so it will record properly (footage in proper folders) even when the internet is down or power cycled / surge (without internet). The Wyze app now should be able to playback the footage without issue even in the event of an internet outage and power surge.
