Read/write eeprom from USB Wifi dongle with the Realtec RTL8187 chip

But... look how easy our dear ladyada solves this task,
like she says "you just need to read the datasheet"  :-+

for sure someone on the forum knows.

Actually you are right that there is probably a datasheet for the EEPROM and you may even find python code to program it if it's some jellybean EEPROM. That's certainly worth looking for.

But you still need to provide means of sending commands to the EEPROM through RTL8187. This is not documented in the public datasheet so just copy it from the Linux rtl8187_eeprom_register_read/write functions.

I will try that, if I can figure it out.

in the meantime I found this interesting article:

and this for those who still read this post

Holy cow  :o

I found The Realtek RTL8187L Mass Production Kit EEPROM modifier program
used in the factory when it was produced.

Program can be used on several chips from Realtek.
You can change all settings in EEPROM  :D including transmit power if you like.
Warning Tx can be set to 1W and will for sure blow up your wifi device  ;D

Download link still works, winXP install
newer version of the program down in the post, so total 2 downloads.

 No more SOIC test clips for me  ;)
