Mar 10, 2017 - Follow these steps to turn your iPhone into a mobile Wi-Fi hotspot. A strong 4G signal, you have instant access to a personal hotspot -- letting. Using the USB cable that came with your iPhone, plug it into your Mac or PC. For Mobile Hotspot devices: A single connected device will experience optimal speeds. Performance will be reduced if multiple devices access data through the hotspot simultaneously. Actual speed, availability and coverage will vary based on device, usage, and network availability.

You need to set a Wi-Fi password in order to set up a Personal Hotspot. To change the Wi-Fi password, go to Settings > Cellular > Personal Hotspot, then tap the Wi-Fi password.* Choose a Wi-Fi password that's at least eight characters long and use ASCII characters. If you use non-ASCII characters, other devices will be unable to join your Personal Hotspot. Non-ASCII characters include characters in Japanese, Russian, Chinese, and other languages. ASCII characters include: • All the letters in English, both lowercase and uppercase • The digits 0 through 9 • Some punctuation marks * When you change your password, any connected devices will be disconnected.

I am going to be buying a MacBook Pro within the next few months (hopefully an updated version if it comes out) for university this autumn. I am wondering, due to the Uni halls having only wired Internet, whether using the hotspot feature of the mac is appropriate for extended periods of time? This would be for the use of my iPhone and iPad which do not connect via Ethernet obviously. I know I could buy a wifi router but was just wondering as this method (via MacBook) would be cheaper and more portable.

The Internet Sharing 'hotspot' feature does work well for this. However, it is WEP only and you are stuck with the default IP address range unless you do some hacking. I use an Airport Express and I find it's very convenient, supports 'more' secure connections(WPA), and is configurable.

It's also always available, never goes to sleep and never drains a battery. It can become a pain always having to have your MBP available for your iOS devices. Being in an University environment, I would want to use something a little more secure then WEP. Also, you can adjusts the signal strength on the AE. Turn it down if you'd like it to just cover your room. Turn it up if there is a lot of other WIFI going on.

I'm not sure what kind of range you'll get on the MBP and how many connections it will handle well. The MBP will work in a pinch. I'd get a dedicated device to save yourself time, and hassle. While you can certainly use your laptop as your Wi-Fi hotspot, you will find certain limitations. Obviously, you can only have Wi-Fi available when your computer is powered on, and connected to your Internet source via Ethernet.

Best all in one utility program for macbook pro. I've done this before on business trips. And it's not hard to setup. But, what I found was it was much easier having a dedicated device (Apple Airport Express) to serve my Wi-Fi constantly than worrying about having my laptop powered on, or connected to the Ethernet cable.
