When troubleshooting a wireless link, which factor do you usually check first: antenna gain, signal strength, interference, or channel selection?
I'm interested in how others approach link reliability in real-world environments. Sometimes a strong signal doesn't necessarily mean the connection will be stable, especially when interference, channel congestion, or antenna placement is involved.
What has made the biggest difference in your experience?

 

Hello,

What you are looking for is called propagation of waves:

Things like wet wood, steel in the walls will disturb the signal.
