Hi Team,

After the latest windows update my laptop (Dell Inspiron 15 7537) crashed, so I had to reset my laptop and I did a clean reinstall (removing my files). After the clean reinstall, my WIFI connects when I start my laptop but after 5mins it does not. I found that the WIFI adapter is disabled, even when I try to enable it says it is enabling but still it does not enable. Sometimes the Network troubleshooter can enable it but again it is gone after few minutes.

First of all, I will like to add, my laptop is OLD so I know if I am backdated. Next, my laptop does not have a battery and it runs on direct power only. I am in process of purchasing one but that shouldn't affect my Network Driver, right?

I googled about the issue as it has happened earlier as well, and from various blogs and posts I have accumulated the following steps and tried with no luck

*Changing the network profile from Public to Private.

*Disabling Power Saving for WIFI

*Network Socket Reset and IP Reset.

*I tried to search for the updated driver but it keeps saying that the best driver is already installed.

*I tried to Uninstall the network adapter and keeps uninstalling without actually doing it.

*WLAN service is also set to Automatic

Am I missing anything else which I should give a try? Please help me as I am clueless about what needs to be done here and I am seconds away to try to install WIN8.1 again which I hate.

Thanks in advance
