Hi  @Wolfdale_3M 

Here are a few suggestions to help you achieve better results while maintaining compatibility with 802.11n:  

1. **Channel and Bandwidth Settings**:  
   - Check the channel settings on your access points. Overlapping channels or interference from other nearby networks can impact performance. We recommend using channels 1, 6, or 11 for 2.4 GHz networks, as these are non-overlapping.  
   - Ensure the channel bandwidth is set to 20 MHz instead of 40 MHz. While 40 MHz can provide higher speeds, it is more susceptible to interference and may cause instability.  

2. **Transmit Power Adjustment**:  
   Adjust the transmit power of the access points to ensure optimal coverage without causing interference. Setting the transmit power too high can sometimes lead to performance issues.  

3. **Client Device Compatibility**:  
   Verify that the client devices (e.g., laptops, smartphones) connected to the access points support 802.11n and are configured correctly. Older devices or those with outdated drivers may not perform well with 802.11n.  

4. **Factory Reset and Reconfiguration**:  
   If the issue persists, try performing a factory reset on the access points and reconfiguring them from scratch. This can help eliminate any misconfigurations that might be causing the problem.
