I tried a another Modem A Conexant. But Windows 10 does not like Modems. I wonder if I went back to Windows 7 it would work. It doesn't matter to me if it is 7 or 10

Did you install a driver for that other Conexant modem?

And why do you even need a dial-up modem?

Yes I istalled a driver, it worked but poorly most sites could not be found. I live out in the country. I have an older puter with Windows Vista I get by , but I don't do much

I presume you have an ISP providing internet service out there in the country. Have you checked with them for recommendations to improve your dial-up connectivity?

If you have an older computer then you have a serial port.  Use an external Serial Modem.

Or a USB dial-up modem.

I have a new Inspiron 3650, if

i restart the computer it is in

windows 7 .

i wonder if it will work a little better with a

modem,

windows 10 was not   designed to be used with a

modem.

If u have a new Inspiron 3650 then it's not exactly an old putter ! When u say you live in the country are u suggesting there are no service providers that you can get dsl or broadband from ? Honestly dial up will work with windows 7 but the problem is gonna be using a pci based card in a computer that only has pci express lanes because they are not backwards compatible so your best bet would be to either get you a wifi hotspot and turn off 4g connectivity so it will utilize much less data per month and for 30-40 bucks you can get 5 gb on a prepaid hotspot which if u don't use a whole lot will be more then sufficient and even 3G speeds will be lightning fast in comparison to your previous connection dial up is pretty much useless on this pc
