Please help, I'm at a loss!! I have a dell vostro using windows 7 that will only connect to secure wifi. This started about 6 weeks ago. Have had it for a few years and always connected to public unsecure networks. I've tried every fix that I could find online over the last 6 weeks. Drivers are up to date. Network card is showing all the unsecured but says windows was unable to connect to network when I try to connect. I've tried turning off firewall both in windows and mcafee. I've tried restoring the computer to a date that I know it connected previously, I've tried restoring to default settings. It connects just fine if I'm on a secure wifi network or cable. If I'm trying to connect to unsecure wifi Ipconfig just shows media disconnected on all fronts. It's a dell wireless 1702 802.11b/g/n adapter. I've also been able to connect to phone hotspot which says its public but needs a code to connect so I'm assuming the difference there is it's secure. Seems that it's specifically unsecure open wifi networks that are the problem (work, Starbucks, etc) Also, I know that these unsecure networks are accessible because I am able to connect with both iPad and iPhone. Any help would be greatly appreciated. Unfortunately I cannot include ipconfig snapshot because I'm at work and only have internet access on my iPad.
