Q: How do I share an Internet connection from my old Macbook to my new Macbook Pro?

If the wireless modem has an Ethernet port, you may be able to share by wire

or share to a different wireless base station (airport apple) so both Macs can

see and use the shared internet by using the AirPort as a wireless router.

There may be a way to use a standard browser and set up the infinity wireless

or see how to change settings that way, but my internet is presently on cable

(previously ADSL) and then it goes to an AirPort base station; these base units

have pass-through for sharing by Ethernet, so that allows more options.

If you have one computer online, you can temporarily share the one connection

so long as the first computer is on and stays running, and has an internet access:

Enable Internet Sharing in Mac OS X to turn your Mac into wireless router:

Is the internet access directly wi-fi or does it come via cable, then to wi-fi? I am not

familiar with infinity or other brands of service; I've almost always set up direct from

a wired modem and before that, from dialup to AirPort Extreme, to share wirelessly.

A wireless bridge or an Apple Time Capsule (shares wi-fi and backup storage) can

be used to allow more than one computer; and that can be easier to setup. You

likely will have to purchase some hardware, to make use of the existing ISP base.

Hopefully with more info, you can get the correct hardware to allow more choices.

Good luck & happy computing!

The internet sharing aspects described in the above links (where one Mac has internet

it can share via a cable to the other Mac or use it's built-in wi-fi as a mini hot spot) may

be some things to try. I see a few that i could test here, but all my stuff is wi-fi from my

AirPort base. (But I have an option to run Ethernet from the ISP's cable modem.)

Your ISP may have another modem that offers Ethernet ports for extending the local network

or to add other devices that do not use wi-fi. So it would have wi-fi and ports for LAN, etc.

Ask, in case they may have rules and conditions of use; or they may offer suitable hardware.

Basic, similar to content in above third-party links (osxdaily) :

OS X Yosemite: Share your Internet connection

Well, the time here is 12:45 AM and I'm going offline.

Good luck in any event...

Connect your second computer to the hotspot the same way you connect the first computer. You can not use your first computer's wifi to connect to two locations, the hotspot and your second computer, at the same time.

I just bought a new Macbook Pro. I have Xfinity Wi-Fi, but the account isn't being recognized on my new Macbook Pro as it is on my old Macbook. Xfinity customer service are of little help and say my login and password should work.

 

Alternatively...

 

Is there a way to share my Internet connection from my old Macbook to my new Macbook Pro? I connected the two computers to the same network, but couldn't figure out how to share the signal wirelessly. I hope there is a way to do so. I think it might be called bridging? My network knowledge is par at best. If I can't do it wirelessly, what kind of cable would I need to do this? There has got to be a way.

Xfinity customer service is correct. Use your Xfinity credentials to connect your second computer to the Xfinity hotspot. If this does not work then work on fixing your computer's configuration so that it does connect rather than messing with some jerry-rigged setup.

You don't need any network files. Everything you need to network is already on your new computer. Just open your system preferences networking and the Xfinity network should show in the left column. Select the Xfinity network and click on add.

I assume wifi is turned on , if not ensure to turn on wifi.
