Internet Sharing Security

I have an original iPhone and 3G iPhone and and iPod touch connecting to my early intel iMac using the internet connection sharing via the airpot card built inside. I am concerned that this connection only allows WEP 128bit and this security level is basically insecure these days. I want to use WPA2 to connect to the mobile devices or any other secure method, so can anyone tell me how this is done please?
I do not want to buy a wireless router and I apologize if this has been asked before.
Many thanks

It is not possible with the set up you have as the iMac Airport card cannot provide the security level you want. Your only solution is to get a wireless router.

Nokia Lumia 720 internet sharing DNS problem

Hi,
I am using Nokia Lumia 720 (OS version 8.0.10517.150) for internet sharing and have had DNS issues lately. When connecting to hotspot with my laptop I get DNS server is not responding error. Phone has data connection and I can browse the internet through phone but cant use it to share the data connection. When I connect my laptop with other wifis it works fine also so the fault must be in Lumias hotspot generation.
Had the same problem few weeks ago but then restarting the device and changing hotspot settings helped but it does not do the job right now.
Any ideas?

Hi kalverk,
Welcome to the forum!
Have you tried using your micro-SIM card with other internet sharing capable phones to verify it the issue is network or device related? Aside from your laptop, have you tried sharing your Lumia 720's internet connection with other phones?
Here are some tips that might help you resolve the issue:
1. If enabled, switch Battery saver mode off: Tap Settings > battery saver > Off. You can also just connect the phone to the charger.
2. Check the signal strength on the phone screen. To increase the signal strength, move around or move towards a window if you are inside a building.
3. Keep your phone in the idle mode. Incoming or outgoing call will interrupt the data transfer until the call ends.
4. Check the cellular data indicator (E, 2G, 3G, H+, 4G) at the left side of the phone's screen. Change the mobile network's highest connection speed from 3G/4G to 2G and back again to make sure that your phone is connecting to the network correctly. Go to Settings > mobile network (or mobile + SIM or cellular or cellular + SIM).
5. Make sure that the internet sharing security type (if not selectable, WPA2 is used) and password settings match between the connecting device and your phone (Settings > internet sharing).
6. Make sure that the operator mobile data plan subscription allows Wi-Fi tethering and your network operator has enabled internet sharing on the phone.
7. If possible, try to create a connection with some other device or force the connecting device Wi-Fi adapter to use 802.11g standard - disable 802.11n mode. On a Windows PC, go to Control Panel > Network and Internet >Network Connections, and right click your active Wireless Network Connection and open Properties >Configure > Advanced, then select 802.11n and set value to Disabled. Once ready, press OK.
8. Connect again, as internet sharing switches off after 5 minutes of inactivity.
Let us know how it will go.

I cannot get my iMac with built-in airport to allow internet connections to Nook and PS3. The devices access the network, but internet connection fails. Internet sharing is enabled, network security (WEP, WPA) is completely off. What to check next?

I cannot get my iMac with built-in airport wi-fi to allow internet connections to Nook and PS3. The devices access the network, but internet connection fails. Internet sharing is enabled, network security (WEP, WPA) is disabled. What to check next?

On an additional note, I've purchased a wireless router and everything connected on the first attempt. It just vexes me that the built-in wireless isn't working as a router. Is this another example of "Mac only plays with Mac"?

How to secure Internet Sharing?

Unless I've missed something, I can't seem to find how to securely share an internet connection in Leopard.
I can enable Airport, share the connection - but there doesn't seem to be any way to secure it - i.e. I want to catch the wireless connection, but I don't anyone else to.
Any ideas?

This is a big help Tim, thanks.
I was forewarned that Belkin Routers last about 3 minutes then expire - so I was not surprised when it slowly sank downhill. Our neighborhood does seem to have seen some new wireless faces appear over the last month or so and on the back of that I did systematically try running from channel 1 (on the Belkin) all the way up to 11 to see if it helped matters. It didn't, and it's at that point I thought the router was at fault. (Incidentally, I purchased a Belkin Ethernet Bridge and that worked perfectly).
So really, and on the back of the Airport Card being a bit un-secure - I think it's new router time.
Linksys WRT54g duly noted - I have recently set-up the Netgear WGT624 and this seemed excellent, and I also have experience of the 834 which has been consistently reliable.
There is another consideration though (are you still reading?) - brand new MacBook (latest spec.), this just crawls on its internet connection. After establishing the router was causing dropouts (i.e. with the Enet Bridge on my G5 nabbing wireless perfectly from an airport card via Internet Sharing) - I was able to see that the MacBook was extremely slow (side-by-side with the same internet pages on the G5).
Any thoughts on that one? (I'm trying to tie this all up in one question I know!).

Secure Internet Sharing Macbook to iPhone 3GS in Mountain Lion

Hi there!
Trying to set-up a secure internet sharing from Macbook Air (Mountain Lion 10.8.2) to iPhone 3GS (update 6.0) via USB Dongle (Orange). The unsecure connection works properly, but thats not an option during my stay in Africa... Somehow the WPA2 personal security (which is the only option in the sharing panel) disables any data transfers. Connection is still present but no data is transfered.
- File Sharing is ON and also with Firewall OFF it won't receive ana data.
- No preferences in the Dongle panel available to allow internet sharing or whatsoever.
- In Internet Sharing panel (system preferences) connection is shared from MF192 (Dongle) using Wi-Fi port.
Someone any suggestions?
Regards!
Anthony

Might have found a related issue.
The Dongle creates several 'identical named' connections (MF192) in network overview...
Is there a way to prevent this?

Just bought a 3TB Time Capsule for a small office. Will have 4 users with MacBooks. What would ne the best setup for time machine individual backups and internet sharing in a secure way?

Just bought a 3TB Time Capsule for a small office. Will have 4 users with MacBooks. What would ne the best setup for time machine individual backups and internet sharing in a secure way?

Set up each Mac for Time Machine backups in the normal way. Time Machine will keep each backup separate on the Time Capsule, so users will only be able to see the backups of their own Mac.
Yes....there are convoluted workarounds that might allow one user to see the backups of another.....IF...they know the administrator password of the "other" Mac.
As far as Internet sharing, all users will have access to the Internet if they have a wired or wireless connection. If a Mac connects using wireless, it is possible to limit the time that they are allowed to connect to the network.
For example, you might limit the ability to connect to the wireless from say each Weekday from 8 AM to 6 PM.
With a wired Ethernet connection, you cannot limit access times to the Internet.

Computer - computer network and internet sharing

I apologise if this has been discussed elsewhere - please point me to any useful links.
I have a G4 iMac and iBook (running 10.4.6) both with airport extreme cards installed. I would like to use a computer to computer connection for file / printer sharign and most importantly to share the ethernet connection to the internet running through my iMac.
I would be extremely grateful if someone could point out how to do this and incorporate a practicable level of security (I don't want any of the hundreds of people in adjacent flats downloading lord knows what through my connection).
Having accomplished this, I then need to be able to create a similar connection when required so that when required I can share the internet connection from the iMac with our PC laptop running Windows XP service pack 2.
So, the simpler the better, instructions for creating a computer - computer network for internet and file sharing between two Macs and following that between the Mac with the internet connection and a Windows laptop.
Thank you very much in advance.
G4 iMac USB 2.0 / G4 iBook Mac OS X (10.4.6)

You don't need to setup up computer to computer connection if your using internet sharing. Once you start internet sharing then your 2 computers are connected togther.
I would be extremely grateful if someone could point out how to do this and incorporate a practicable level of security (I don't want any of the hundreds of people in adjacent flats downloading lord knows what through my connection).
The problem you have is that if you enable internet sharing on one of your macs to share its connection over airport then the only level of security you can enable is WEP encryption.
The problem with WEP encryption is that it offers no real security and can easily be cracked. WPA is the only security you should consider using and unfortunately OSX does not have WPA encryption functionality when using the built in internet sharing function.
Your best solution is to get a wireless router that has a SPI firewall an WPA encryption. Depending on what your current internet connection is and how it is provided would determine the best kind of router to get.

Video Chatting and Internet Sharing at the same time.

Does anyone know why video chat communication cannot be established while internet sharing, or how to remedy this problem by (what I imagine would be) opening/closing/redirecting a few ports?
More specifically:
I share my ethernet connection through my airport connection to my iphone with the ip host/client scheme of 10.10.0.1/10.10.0.2.
If I don't turn internet sharing off, a video chat connection cannot be established.

Would you want any phone call due to come to you to go to both your landline and your mobile/cell phone particularly if you did not have both together ?
It is mostly about the specific needs of iChat needing to be able to place the computer in a specific place compared to the rest of the Internet.
If you have your Cell phone divert to your Home phone or vice versa how do you know it has also not been answered ?
More to the point how do you know that someone answering a call you have made to them has not been answered by someone else ?
In practice you know only one phone can be answered because of the mechanisms put in place that allows you to make the link between cell and Landline.
It is same for the process used to connect iChat to an iChat Buddy. It makes sure the Network has been set up correctly and is secure.
It is less about making two connections to the internet in the belief it will be twice as fast.
(Check a Download in a web Browser and see if it is really any faster with two connections or if Web Browsing is any faster.)

Internet Sharing not working in 10.5.8

I'm running a Mac mini (PowerPC) with Leopard.
My situation is a little different from most. My Mac mini is connected to my network via AirPort. I use it in my home office, which is located some distance from where my Internet connection comes into the house.
I have a Nortel IP phone for working remotely from my main office. In the past, i have successfully used it with my Mac mini via Internet sharing. By turning on Internet sharing and connecting the IP phone to the Mac mini via Ethernet, it finds its server and connects without issue. I do get occasional dropouts due to the wireless bandwidth, but nothing too severe.
A few weeks ago, i updated the Mac mini to Leopard, and applied all the updates to bring it up to the most recent version available, 10.5.8. My Internet sharing no longer works.
I have tried reinstalling the 10.5.8 combo updater. I have tried the workarounds where a kext from 10.5.7 is swapped out for the more recent one. I've tried rebooting. I've tried manually setting the DHCP address on the Ethernet connection. Nothing works.
Apple, please issue a fix for this issue. My only other option at this point seems to be an archive-and-install of Leopard, then applying the 10.5.7 Combo Updater and freezing my machine there.
Are there any other fixes or workarounds that can get Internet Sharing working again? It works fine on my Snow Leopard machine.
This bug is a huge pain in the butt.

I'm having this problem but it was after I installed security update 2010-003, that put my at OS X 10.6.3.
My internet sharing isn't working but moreover, my Ethernet port isn't working at all. I can't find anything on this issue. I just updated this morning and I usually use the internet sharing to share the airport connection through the Ethernet port and have never experienced a problem until now. Now matter what I do, after restart, putting it in sleep and everything I can think of, it still says Ethernet cable is unplugged.
did you ever find a fix?

Internet sharing via dongle, how to set password for wifi network created?

I am using a USB dongle with my Mac book Pro to share internet through AirPort, so that i can access my mac book's wifi from my iphone. This works great, but it is an open network and I woud like to set up a password.
If anyone can point me in the direction I would be very grateful!
Thanks

If you are using OS X's Internet Sharing feature, then you can configure wireless security on your Mac's internal AirPort Card but are limited by the OS X version that you are using. It was not until Mountain Lion that Apple provided WPA2 security. Prior to this only WEP was available.
You configure Internet Sharing via System Preferences > Sharing > Internet Sharing. (I don't have 10.6.x on any of my Macs so this may be different for your case.) Once you configure what is shared, you can then add wireless encryption.

Internet Sharing Ethernet to WiFi disables WEP password on Mac Network?

Hi all,
I have a curious problem, I'm trying to use internet sharing to share the ethernet connection to my iMac with my iPhone and iPad over wireless (no wifi where I live).
I can create a network with WEP fine, name it whatever, encrypt it with whatever, my iPhone can connect to it etc. but as soon as I turn the tick box for Internet Sharing on, the network loses its WEP encryption (so it's unprotected) and its name reverts back to "My Name's iMac", even if I set it up as "3423rfgdfgfdg" with WEP.
Basically turning on Internet Sharing overrides all the options I set up on the network, name, security etc and my WiFi turns into an unprotected internet source and a broadcast of my name, something I don't want where I live.
Am I crazy in thinking this is a bug not a feature and there must be some solution?
I honestly look forward to seeing what you guys think, I'm stumped.
This all used to work perfectly on Snow Leopard, I remember quirks during Lion but I got it to work in the end but I'm on ML now and it just doesn't want to work.

Hey, thanks for the suggestion but that's exactly what I'm doing.
See how after you've selected Ethernet in 'Share your connection from' and WiFi in 'To computers using' you then have to click the tick box ( http://cl.ly/image/1v191f2R1F1i ) on the left hand side to actually start the whole process?
Well regardless of whether I start it up in the 'Sharing' pref first, then set up Wireless options, or set up wireless options, then start it up in the 'Sharing' pref, whatever settings I choose get overriden as soon as I start the sharing.
The network just defaults to 'Asad's iMac', without protection. I don't understand why.
P.S. on a side note when creating networksI'm not offered a WPA2 option. Only WEP 40-bit or 128-bit. Dunno if that's connected: http://cl.ly/image/2X2g3w3y0B34

Similar points to note - Today when I tried to make an App Purchase - The security info screen ( new additon - http://isource.com/2012/04/11/iphone-app-store-security-info-alert/ ) popped up but I got a blank screen for the securtiy questions screen ... It was not loading the screen ... Some games the game center invite does not work through my Internet sharing (tried in MetalStorm) ... but works fine thorough wi-fi or thether ...
What could be the problem with my iMac s sharing? Any suggestions would be really useful /// Thanx in advance
I am running Lion ... and I have updated to the latest Airport software ...
Only thing I tried was changing the DNS ... but that s not related right ?

Powerline adapters use your home powerlines (mains a/c) to connect your devices via ethernet to your modem, they're easy to set up and the they TOTALLY fixed my ATV problem, the problem seems to be with the wireless. I've been trawling through apple discussions, and did found a workaround to my problem https://discussions.apple.com/thread/4222883?start=0&tstart=0
but its just a workaround :/

Macbook pro internet sharing to non apple with password ?

Hi there,
I have a MacBook pro, in my place I connect to the Internet through LAN cable, and I have 3 friends who I share the Internet with (Windows)
When I share my Internet with them I cannot put a password (40-bit or 128-bit) because when I do their laptops says password is wrong
So I leave it without one, and that gives me a big headache because my network is exposed to every one and I’ll have a slow Internet speed
I am searching for an answer since forever , Is there a way to protect my network ?
to have a password and let other non apple laptops access my network?

It hardly matters. The only security available with Internet Sharing is WEP, which can be cracked by anyone in a few minutes. Use a real wireless router with real security, or don't bother with security at all and accept the consequences.

Connecting ipod touch to internet via internet sharing

My MacPro was connected to the internet. My ipod touch showed that it was connected to the MacPro via internet sharing, but I could not get the ipod to complete the connection to the internet. I selected "Allow all incoming connections" in the MacPro system preferences>security>firewall and the ipod could see the internet. Success.

If we wanted to open only individual ports (or a range of ports) rather than disabling the whole firewall, which ports would we leave open?
TIA,
George

IPad 2 connection through internet sharing

This may be answered somewhere else on the discussions, but I would like some assistance in connecting an iPad 2 to the internet through an iMac that is connected through an Alltel wireless card. In the iMac, I've turned Internet Sharing on, and the airport is also on. What am I missing ? ? ? Or is it not possible ? ? ?

Jack:
I wrote this on an earlier thread and it seemed to help another user so give it a try. Bold type is specific to you. Ignore anything you already know. I'm not sure if you can share the connection from a wireless connection (you CAN share from ethernet) but these are the steps and it may work.
OK if you selected Internet Sharing on the Mac you must also select
Share your Connection from - Ethernet (select ethernet) I think you would choose the Airport option since your are using a wireless card
To Computers Using - Airport (your iPad is the computer using Airport in this case)
Then you may have to select the Internet Sharing option again - put a checkmark in the box
Then go to Security in your preferences and select Firewall - turn off the Firewall to allow incoming connections to your Mac
Make sure you have Airport enabled on your Mac and go up to the Airport icon at the top of the screen, click on it, and drop down to select - Create Network. A box will come up and it should offer your computer's name as the default network name. You can name the network whatever you like. Then create a password.
This should be what you need to do to get connected. Once you do all of the steps on the Mac, reboot your iPad, go to Settings>WiFi>Network and select your new network.
