Hello! I'm really having trouble with my wireless signal outside of my house. I would like to know what's the safest and the most efficient tweaking I should apply to my router (running Tomato v1.28 on a WRT54GL v1.1) in order to increase it's range/signal. I've read a couple of articles suggesting me to buy a wireless antenna instead of tweaking my router. An additional antenna will certainly increase the range, but still I'm in a dilemma which will be the best option. Is there anything I could do without buying an antenna? Any help would be appreciated! Thanks!
