Well 99% of what you said in this reply is over my head as I am not tech savvy, but I appreciate all the effort.  I finally found a local computer store, explained my issues and they said they could remote in when I got home. So I called them, they remoted in, went to "command prompt" and 'run as adminstrator' and typed in ipconfig /flushdns  Works great now, no lag time even with 4 websites open. Thanks
I have a Inspiron 3268 desktop, 8 years old, trying to locate a driver to upgrade it to 5ghz so I can connect to my 5 GHz WIFI. Right now I am on 2.4 GHz, running Windows 10, can this be done? I'm not sure what other specs you need to answer my question.
