I also have a NeWiFi D2.
I confirm that my results are also better with EEPROM from minihere.
What WiFi settings and firmware version did you achieve the best stable results? @jaclyes89, @Eduardof187, @motocrossmann
So far, I've only tested the recommended settings listed here on the thread.
Here are my best results:
2.4G
channel: 1; 40 mhz; country: FR; DTIM Interval: 1; tx-Power: 8 dBm
- ↓: 40mbps
- ↑: 30mbps (max from ISP)
5G
channel: 36; 80mhz; country: FR; DTIM Interval: 1; tx-Power: 23 dBm(199 mW)
- ↓: 240mbps
- ↑: 30mbps (max from ISP)
ISP: ↓: 300mbps ↑:30mbps
Tested at a distance of about 1m.
I am using the OpenWrt 19.07.7 r11306-c4a6851c72 firmware.
PS: Stability has not been tested.
