Attached is a picture of my apartment.
The problem I am having is that my download speed drops dramatically in the living room where my tv/laptop is. If I am in the same room as the router or in the bedroom (on the right of it in the picture) I have no problem maintaining my max internet speed (25mbps) but in the living room I max out at about 2-3 mbps. I've read that microwaves and central air units can block wireless signals so I am guessing that's the problem. However, on the two laptops in the living room, I can usually get 4-5 bars according to Windows with very good to excellent signal strength.
I'm running a Linksys WRT320N with Tomato firmware. It's running at 2.4ghz (unfortunately I can't run it at 5 ghz for compatibility reasons).
I'm thinking it might be the router but it may also just be that there's too much interference. The distance from the router and the living room isn't huge - about 25-30 feet.
Any thoughts on what might be causing my problem and a recommended solution? I've looked at a couple options but don't really want to invest in something unless I have a good sense it will work. Due to the way the building is wired there isn't any possibility of moving where the modem is located and because I rent, running network cables through the walls isn't an option either. Right now I'm leaning toward trying a new router but am unsure if that would get past the interference if that is truly the cause of the problem. Any help would be much appreciated.
Thanks in advance.
