AppleTalk has nothing to do with the Internet. They are different and incompatible protocols.
The extension that provides Internet communication in OS 7.5 or 7.6 is called OpenTransport. You can download a CD image containing the OpenTransport installer at this page: https://macintoshgarden.org/apps/apple-legacy-cd-2000-v10
It will install the TCP/IP control panel that you use to select an internet address and gateway.
The image also contains the 7.5.5 updater which fixes a lot of bugs in 7.5.3.
You may find that OSes that old are very limited to what they can do on the Internet these days due to lack of support for things like modern https protocols which just about everything requires. It can still be useful to get stuff on and off those machines, but you probably won't be able to use it for any general purpose things like browsing most web sites.
