Update: The folks at Dell Wireless were able to fix it. What worked was going into the Advanced properties for the network card adapter and setting "Atenna Diversity" to "Aux". As soon as that was changed, it worked like a charm.  My only guess is that it somehow engages the wireless card's antenna?  
Hi all - first time posting but long time Dell owner.Yesterday I received a brand new Mini 10 (model 1010).  Out of the box, the wireless performance is really, really poor.I have two Dell laptops, a Dell desktop, and an Acer netbook.  All of those systems connect to my WEP-enabled wireless network and receive between "Very Good" and "Excellent" signal strength at 54 mbps throughout my entire property. From the same locations, the Mini 10 receives "Very Low" to "Low" at rates as low as 1 or 2 mbps.  This is regardless of what Advanced driver settings I tweak for the wireless card driver.  Even within close proximity of the wireless router, the Mini 10 gets at best "Good" signal strength and almost never sustains 54 mbps. I have a Belkin Pre-N router that is working without any issue for all other wireless devices in my home.  The internal diagnostics of the Mini 10 wireless card all pass.Any ideas if I have a hardware issue on my hands, or could this be driver-related?  Would hate to send the unit back to Dell but I'm getting really close to that because the system simply isn't usable with the current WiFi issue.Thanks!!-Joe
