"invalid antenna gain in sprom"

[MJ]

Greetings Carmel,

1. sprom - stores the mac address, vendor details etc. It also stores 
maximum transmission power, hence the message.

2. Looking at the code, it's invalid (probably no value) and so it sets 
a base power level. No harm.

3. Look at man page for bwi, does this help.

4. Is it showing any errors etc in /var/log?

Hope this helps,

Mark
