Hello and thanks for your reply. Found out the solution was Device Manager -> Network Adapters -> Dell Wireless 1703 b/g/n -> Properties -> Advanced ->802.11n Bandwidth changed to 20MHz/40MHz Auto. [IMAGE]
Hello everyone, I just bought a new Dell Inspiron 3520 (service code: ) which came with Ubuntu.  Although I had to install windows 7 32 bit and I am facing a driver issue with wireless adapter. When I try to connect to the preferred network I get "Unidentified Network - No Interntet Access". I know this is a driver problem because it works well on Ubuntu. So as the original configuration from Dell site lists:  "WIRELESS : DELL WIRELESS 1703 CARD" so I downloaded this driver : [URL] with no success. Is there anything I can do? Sorry for the long post. Thank you in advance
