Hi, I had the same problem with an Acer laptop. The signal showing on it was weaker than a desktop pc when placed side by side. I installed bigger aerials on my linksys router but didnt help much. My solution was to hard wire another router closer to where the laptop was used. The second router was configured as an access point, and I now have full strength showing on both laptop and pc. The only downside to this is connecting the 2 routers by ethernet cable, you may or may not be able to easily do that?
