EAP211 Bridge disconnecting almost everyday
Hello,
I have an EAP211 bridge between 2 buildings.
The antennas are mounted on the roofs of the buildings.
It is a school. The bridge goes from the main building to the cafeteria.
Almost every day, at almost the same time, the cafetaria antenna disconnects.
This corresponds to the arrival of the students.
However, as mentioned above, the aerials are on the roof, so shouldn't encounter too much interference. But it seems to be linked
How can I find out exactly where my problem is and avoid it?
I've already reduced the channel width to 40Mhz.
My antenna is at -59dbm
Thks for your help

Hi @Cotchet
The EAP mostly disconnected when the students come, which indicates it is mostly caused by the congestion of the wireless environment, please follow the following suggestions to do wireless optimization
1. **Confirm the Cause of Interference**
- **Spectrum Analysis**: Use a Wi-Fi analyzer tool (e.g., NetSpot, Ekahau, or the built-in tools in your EAP211 management interface) to check for interference on the 2.4 GHz or 5 GHz bands. Look for overlapping networks or non-Wi-Fi devices (e.g., microwaves, cordless phones) that might be causing interference.
- **Channel Congestion**: Check if other Wi-Fi networks are using the same channel as your bridge. If so, switch to a less congested channel.
- **Non-Wi-Fi Interference**: Devices like Bluetooth devices, wireless cameras, or even fluorescent lights can cause interference. A spectrum analyzer can help identify these sources.

2. **Optimize Antenna Alignment**
- **Line of Sight**: Ensure there is a clear line of sight between the two antennas. Even though they are on the roofs, obstacles like trees, walls, or HVAC units could cause signal degradation.
- **Signal Strength**: Your signal strength of -59 dBm is acceptable but could be improved. Aim for a stronger signal (e.g., -50 dBm or better) by adjusting the antenna position or height.
---
3. **Adjust Wireless Settings**
- **Channel Width**: You’ve already reduced the channel width to 40 MHz, which is good. Consider testing with a 20 MHz width for better stability, especially in a crowded environment.
- **Transmit Power**: Increase the transmit power on both antennas to improve signal strength, but be cautious not to cause interference with other devices.
---
4. **Environmental Factors**
- **Weather Conditions**: Check if weather conditions (e.g., rain, fog) are affecting the signal. While this is less likely, it’s worth ruling out.
- **Physical Obstructions**: Ensure no new obstructions (e.g., construction, new equipment) have appeared in the signal path.
---
5. **Firmware and Hardware**
- **Firmware Update**: Ensure both EAP211 devices are running the latest firmware.
Hardware Issues: Test the bridge with a different set of devices to rule out hardware failure.
