I agree with Erik- Like so many other key specs we look are tuned into with consumer electronics each vendor will often publish there specifications in a different unit of measure. Laptop batteries are a perfect example. Vendors will post their numbers as miliamp/hours, watt/hours, amp/hours, number of cells, etc. <div>
<br></div><div>Having said that I am sure there is some report somewhere where wifi has been scientifically analyzed Outside of that I have heard of people having success of purchasing a usb hi Gain antenna . I purchased one for a laptop to help with a similar aforementioned signal problem. I even went to the extent of getting a short usb extension cable so I could mount it high on the screen bezel. After all that work i did not note any increase in performance. I think there are other brands where people have had good success.</div>

</div>This sort of thing is quite hard to pin down. The performance<br>
discrepancy could be caused by any one (or multiple) of the following:<br>
<br>
- radio hardware<br>
- antenna design<br>
- antenna placement<br>
- internal RF interference within the laptop body<br>
- Wifi chipset firmware issues<br>
- sub-par OS WLAN drivers<br>
- etc. etc.<br>

</div>In most situations, the presence or absence of external antennas is<br>
neither here nor there. At 2.4 and 5GHz, antennas do not need to be<br>
all that long. The wavelength of 2.4GHz signals is around 125mm and<br>
5GHz, about 60mm. Figure a half or quarter-wave antenna, and you don't<br>
need all that much space. Frequently laptop manufactures will route<br>
wifi antennas to the top of the display panel. In Apple's case, I<br>
believe they put the Wifi and bluetooth antennas in the hinge area of<br>
the body, as that's the only non-metal (read: RF transparent) part of<br>
the laptop.<br>
