Hey, i am not sure about increasing wireless range. But i got two options. One is using anthennas, and the other one is using the Linksys Wireless G Range Expander. Which one is better? Should i go for the former or the latter? I want my range to be increased drastically, that is able to reach a distance of at least 100m with obstacles such as walls. I am currently living on the 4th floor in a flat, and i want to be able to access the internet on the ground floor. Please give your comments. Very much appreciated.
