How many users can be connected to an iPhone's personal hotspot? Does the limit differ from device to device? I want to know the limit of maximum users.

I'm looking on Apple's site and can't find any published limits on how many clients can connect to one iPhone / iPad with cellular tethering enabled in the US.  Setting aside the obvious limit where 1,000 devices would overwhelm the data connection in practice if they all want data at the same time, is there a hardware or software limit of perhaps 5 or 10 devices that can connect to one device over WiFi?

If I lose my iPhone, and I use remote wipe to prevent my confidential data from being stolen, then can I still use Find My iPhone to locate it on a map?  I'm assuming not (since it resets to factory settings), but I wanted to double-check.

I came across a post which suggests:      Do Not instruct people to add PPAs unless it is necessary   And one of the reason it has mentioned:     There is a finite number of PPAs that a user can add.   Really?  Is there any limit to adding PPA's to the system? Why?  Also, on what factors do the limit depend?

I recently got an iPhone 4. At home, it connected to our wifi and worked perfectly. Now I am at school. My iPhone is now connected to the wifi here, it says that it is connected and has strong wifi signal. However apps that require internet like email, Facebook app, and online games (like words with friends, etc) load and stall showing "updating". All apps are unable to actually update. It shows it is loading for forever.   What can I do to fix this?

Is it possibe to change the channel my phone broadcasts its Wi-Fi hotspot on?   Right now it's using the same channel as my neighbour (6). My router is reporting several unused slots.

This will probably sound familiar to most of you... In my home, we have a whole bunch of devices that can be charged via USB (two iPhones, a BlackBerry, an iPod Touch, etc ad nauseam). We also have a bunch of USB chargers, each of which has a single USB port on it. I'd like to have something permanently connected to AC power with at least 4 USB ports on it, so we can just plug devices in and don't need to go looking for a free outlet.  So here's the question: if I buy a powered USB hub, will that do the job even if I don't connect it to a PC? Ideally if you have a hub that you can personally verify will be suitable, let me know the manufacturer and model :-)  Thanks in advance!  EDIT: The solution I eventually went for was this:    There's also a US version here:    It arrived yesterday, so I used it to charge the following devices, all at the same time, overnight last night:   32GB iPhone 3GS 16GB iPhone 3G First-generation iPod Touch    I can't say anything about the charging speed (as I left it overnight) but all devices were fully charged this morning.

Many phone games restrict the number of actions you can take in a given amount of time. I don't get what is the purpose of this limitation. Is it only to force the player to buy additional turns? Some games don't even allow this for some turn "kinds" (like action A can be played again by spending real money while action B cannot be played again by spending money).  Another possible reason would be to limit the bandwidth usage to their server and make it more predictable over time, but I can't see phone games using so much data.

I don't add these web sites to the restricted list. Is the iPhone sending every page I visit to Apple? Random surfing will encounter a random  restricted site. In this case it renders this app broken because the 'allow' link doesn't work. Setting is currently set to limit adult content which allows me to use a white list and blacklist. I never added this site to blacklist. I only blacklist 3 sites.     How does iOS know that a website is restricted? Does it send it every page I visit to Apple?   How does iOS know if a website is restricted? Does it send it every page I visit to Apple?   See this is the BS I'm talking about:    iOS 10.1.1

In my iPhone settings where I'm supposed to turn Wi-Fi on or off, it is just grey &amp; says 'No Wi-Fi'.  I have reset network settings, restored phone, re-synced everything, but still have this problem. Does anyone know how to fix this?

I would like to make an Android device as hotspot. I will put it in my roof so it will receive vetther signal, and turn in its hotspot. I want to make that hotspot accessable by certain devices only by register their MAC adress at the hotspot device.  How can I do it? I don't see any option in the hotspot setting so I can do it.

I want to limit 1 connect per 5 seconds using IPTABLES for people, which are connecting to port "12871/12881". I was trying to find rule for it, but ineffectively. It must be like a "queue" of connects - for example 1 connect per 5 seconds.  I had here discussion:   but Im not able to reply on this account, previous was unregistered and logged me out.

I am developing a niche social networking iPhone app of my own.   I was wondering if it would be best to allow the user to connect to social networks such as Facebook and Twitter to login to my app (and of course an eMail/Password fallback) or just go with regular eMail and Password login.  Any thoughts would be appreciated! :)

In , someone is asking how to tag more than 50 people in a picture. He even has a link to someone who has done it.  I can only tag up to 20 people.  How are some people able to tag more than 20 people?

I'm not sure if I have an issue or if what I am seeing is by Apple-design.  I have an iPad Pro (11.4) that I have the Personal Hotspot switched on.     My iPad Pro is active and screen on. I connect my iPhoneX (11.4) to the iPad Hotspot. Everything works fine.  I sat working on laptop and then the iPhone X and iPad screen locked.  After X minutes I then unlock iPhone to check email etc..  The iPhone X has disconnected from the hotspot and is back to using the cellular plan on my iPhone.  If I go to Settings -> Wi-Fi then my iPad is not listed.  To make the hotspot reconnect I have to go back to my iPad and toggle the Personal HotSpot switch (On -> Off -> On).   Is this by design or not?  Should the iPhone remain connected if the devices screen lock?

On the settings under iCloud, if I try and log in on the ID I created this morning, it says that the maximum number of ID's have been activated on this device. When I try and create a new account underneath, it says that this device is not eligible for one.  How can I resolve this?

I can't connect to wifi with my laptop but I can connect to wifi with my phone, ps3 and ipod etc. I can actually connect to the internet with my laptop when I use a cable to connect to the router. Does anyone know what my problem is?  My connection worked perfectly before, but 3 days ago it just stopped working. I have windows 8. In the corner it just gives me a perfect bar connection and I cant find any solution on internet.  Thank you

I'm being forced to use my Macbook more and more with my metered 4G connection. I really need to keep data usage limited. Windows has an  mode which really helps with this.   What's the best way to handle this issue in the OSX world? Perhaps some use of the firewall? Is there any sort of logging happening as to what is using the network?  Thanks for your help :-)
