mibile hotspot to desktop computer connected with no internet

Hi, ive been having this issue trying to resolve it for a week now... I posted another post that has alot of veiws but no replies and figured I would repost as I have uncovered a new piece to the puzzle that will hopefully help....
Ok.... I only have internet thru my phone until I can get this hotspot working... I have tried running the ipconfig sequences with no solution. I have deleted deleted avg per my provider which says everything is running correctly on there end... my wifes tablet and other phones can connect and use the internet my desk top connects but with no.internet I have checked all th ipv4 and 6 and is on automatic my computer says its configured correctly and can read the dns server. I use net gear and the pc says.its running properly. My provider connected me to microsoft who told me to call dell. I called them and warranties were up and they wanted 100 to 200 dollars to fix the issue... but while I was on the phone with them I accidently disabled something that asked me to enable thru admin and I clicked it and it came up that I needed to plug.in my ethernet cord to work for the connection... I cant find the ethernet under the network adapters and am not good with computers... my guess now is maybe something is configured and trying to run thru a main line and not thru my netgear for the actual internet part... I have tried soooo much and have posted on other forums and even this one and have gotten no help to solve this issue so far... can anyone plz help me solve this issue?

Ty for responding to help.... I have my desktop computer my wifes phone and her tablet that is all that I have and access too... I think I know where u are going with the flash dive... somehow find a way to copy the drivers to the flash drive to be able to reinstall after right? Lol pretty smart I didn't even think about that lol... im not sure what u need from the wireless connection... all I know or believe is its connecting thru the netgear. I tried a few more things today and tried to trouble shoot from incoming network and said it was a possible firewall block so.I ran as admin to fix it automatically and it said.it did but didnt work then in clicking continue it said.it.wasnt fixed and.more information was needed... I do have a empty 8gig flash drive and will look at and try to do the clean restore point now..... I lost everything in being.locked up but the computer so I have no discs anymore for anything.... so what do.I do next?

After re reading ur post.... im not sure if its good to copy the drivers from this.computer or do I need to.try and.find a way to another computer?and.if its from the netgear site is.it gonna cost money?

Oh u got back to me soo quick this is awesome ty u so.much yes I have usb chord I can plug into the phone its net gear genie n 6oo wireless usb adapter wnda3100v2 and adapter software is version 2.0.0.1

I do have a flash card reader but dont have the disc to put into it with the sd card anymore either... I tried the ipconfig sequences the only one that wouldnt work is ipconfig/renew ... I tried to ping the ip address today and google chrome and that wouldnt work either although for the ip address I did get the four responses back... ask as much as u need Iwill probably ask alot too lol iI want to learn and get this fixed at the same time lol :)
