I have the idea of installing either a 11b or 11g wifi lan. Someone told me 11g is better, but I think he meant in how much data can be transmitted per second. I have the idea that this high data rate would translate into less range and penetrating power. I can go 11g if the range is the same as 11b, but if 11b goes significantly further, I want to chose 11b. The data rate is really not all that critical, but going through walls and such is. Please advise.
