Acer windows 7 wireless signal loss

Hi,
I have new Acer Aspire 5739G laptop and fresh Windows 7 on it.
The wireless card is Intel WiFi Link 5100.
The problem is that wireless works only in short distance with access point - max distance is about 5 meters.
In that distance everything works fine.
But if I go farther or to another room it disconnects.
With other laptops all works fine even on very large distance.

I tried such things (nothing helped):
* uninstall, reinstall or update drivers
* install newest drivers from Acer site
* install newest drivers from Intel site
* tested with xp & vista drivers
* on network connection properties unchecked all things except tcp/ip v4 protocol (microsoft networking,sharing, link layer topology,QoS, TCP/IP v6 ..)
* disabled homegroup
* on adapter properties changed signal frequencies (1,6,11),
* on adapter properties changed standard type to work with: 802.11 b or g
* on adapter properties changed signal to MAX, don't use power saving
* disabled internet security, firewall
* Changed access point signal broadcasting with no encryption or wpa
* it disconects from another access point the same way (problem with system not wifi AP)

Maybe something forgot to say, but there was few hours of testing and can't fix it :( 

Waiting for Your advice

Do you have another OS you can put on that laptop to see if you have the same problem? If you do, you're probably looking at a bad wifi card. Depending on how old that model is, you should call Acer support to get the card replaced.

Yes, these were my options to do too:
-> check with XP
-> if doesn't work, get Acer support

It doesn't work with XP too. It seem's that I have to go back to the shop.

The same as spmcol2007 said.

I would wager that the antenna is physically disconnected... they typically run (internally) up the sides of the screens on laptops. After reassembling a laptop after an LCD swap, I nearly forgot to connect this back. That (besides MASSIVE RF interference) is about the only thing that could explain your ultra short range.

Brought it back today to Harvey Norman. They tried it and agreed that it was faulty and gave me a new laptop, same make and model, without any debate. The new one is working perfectly.

I have this exact same problem. Got the thing on Tuesday finally, and discovered yesterday that the range is appalling. After much fiddling and driver downloading and such, phoned Acer and they told me to reinstall 7. Had no effect, and now Acer close their call centre at 5.30 so I can't phone back till tomorrow. So yeah, going to either have to send it off to Acer, or call Microdirect, although after I purchased this model, they went out-of-stock on it so I think it was the last one.
