I purchased a WRT54G V. 4 yesterday because a friend told me that once I upgraded with 3rd party firmware, the coverage range would increase by a lot. I am in a three story house with the router being on the very top floor. My last router, the Linksys BEFW11SF had horrible coverage. After installing this new router and upgrading with HyperWRT, I have only noticed a slight increase in coverage. There is still one area of the house that still can't get very much and it's only a few feet away. Is my friend right? Does firmware really have anything to do with range coverage and if so, is there some setting I can set to increase or is my house just blocking all signals? Thanks for any help!
