Vostro 1400 Vista random disconnect from wireless...more

Hi,

 

I have a new Vostro 1400 with Vista Basic. Laptop new from Dell 2 weeks ago. What has been happening is that is random disconnects from my wireles router a Linksys WRT54G version 4. (factory stock, never modded, Inksys latest firmware)

I also have 2 other laptops from 2 different manufacturers with XP SP2. I have had them for 2 years same with the router. I never had and disconnecting issues. So my questions are:

 

1) Is it the Vista OS on the Dell 1400 ?

2) Is the Dell 1390 wireless card ?

3) Should I have upgraded to a Intel wireless card?

 

I have disabled the firewall on Vostro and it did help some. I do not have any other software installed except the Dell factory image it came with. It disconnects 20 minutes or 2 hours. It can do it anytime in between or even longer 3 or so hours. I have all 3 laptops side by side and the other 2 never have disonnecting issue. I looked at the driver for the wireless 1390 and it has the latest. I tried different channels on the router still the same disconnect issue.

 

Any ideas?

 

Thanks
