I purchased the Inspiron 14 5000 series laptop from costco a week ago. I am experiencing major wifi adapter issues, which if you look at the following thread on the community support forums, appears to be a design flaw with the location of the wifi radio in this (and a few other Inspiron) models.  See: [URL] This is a showstopper for me and I'm going to return the laptop to Costco ASAP. I'm looking at a similar replacement machine (non-Dell) and have found a decent deal at Best Buy for a Toshiba Satellite 14" touchscreen with similar specs as the Dell.  [URL] I hope this helps others who are considering this laptop or who have purchased this laptop to understand the issues with the Intel Dual Wireless 3160 adapter. This issue is not an isolated incident - just do a google search for "dell inspiron 14 5000 wifi issues" and there are many stories from customers with similar problems. Shame on you Dell for putting out such a sub-par piece of hardware. I'm not impressed.    
I have a brand new Dell Ispiron 14z Ultrabook.  I keep having problems with Wi-Fi connectivity.  I can use the Ethernet connection fine, but when I try to connect to Wi-Fi I keep getting no access or limited connectivity.  I have other devices and laptops that work fine on the same Wi-Fi networks.  Please help.  I am hoping I do not have to send this laptop back but if Wi-Fi does not work it kind of defeats the purpose. thanks Dave
