I have just uploaded the free version of alchemy to my WRT54G to increase range and it works great. It gets pretty hot with high tx power so I keep it around 90mw. I am interested in installing freya on my wap54g which is in repeater mode to cover some dead spots in my house. Is there anything I should be aware of before flashing the ap? How high can you safely set the tx power on each unit without damage? Keep it simple please because I am only technical enough to be dangerous.
