I use OpenWrt on x86. I use this build but added a WiFi card and antennas. At first the WiFi performance was very good giving me great speeds and range. Some time ago performance degraded. The signal range is extremely limited giving me disconnects on my phone when I’m 4 meters away.
How could I debug what the cause might be. Any ideas?
Wifi is generally kinda hard to troubleshoot, but you could try to set the “log_level” to 0 to maybe have some better hints in the logs. I could also tell you to look at your transmit power, but I assume you’ve already done that and that’s not something that should change with time anyway.
