Internet connectivity barely working

Hi All,

I have an inspirion desktop 3250 almost 45 days old.

i3 ,8GB , Windows 10.

After a dell update (what was updated i don't know ) ,suddenly my wifi has stopped working or it barely works i.e.it initially opens the home page and then stops working.

Other devices in my home network are fine . I checked that network signal strength is proper (it was working earlier so no chance of router problems ).

I went to the device manager. There for the wireless driver i found some events like "Device install requested " and information says requires further installation.

I went to the dell site and downloaded the latest driver for wireless adapterem and updated in my system. I downloaded this one. Dell Wireless 1707 WiFi + Bluetooth Driver  But internet still does not work

Please help.

Best Regards,

Saurav
