the kernel which is the firmware.

การปรับค่าเพื่อประสิทธิภาพ
============================
Do not raise your TX value
should fix signal issues with better antennas not power.
Many routers do much better with LOWER TX values,
around 40-50 especially those with the crappy internal antennas (linksys ashtrays).

ยิ่งปรับ tx power เยอะ, speed รับส่ง ยิ่งต่ำ
