Internet Sharing - reducing wifi power

I'm sharing my Mac's internet connection over wifi to my iPad when I'm at work. Is there a way to reduce the output power of my wifi? I don't really need a signal beyond my cubicle. How would I reduce the wifi power settings to as low as possible on my Mac when it's in ad hoc mode?
Thanks a lot

Are there any Terminal commands that would allow this?

Does Airport Internet Sharing Support WIFI Mode G?

I am trying to connect a Nokia N810 Internet Tablet to the Internet via Internet Sharing. The N810 only supports B and G mode WIFI. I can't get a connection. Does Airport Internet Sharing Support WIFI Mode G? Do I have to configure for this?
Thanks

I am trying to connect a Nokia N810 Internet Tablet to the Internet via Internet Sharing. The N810 only supports B and G mode WIFI. I can't get a connection. Does Airport Internet Sharing Support WIFI Mode G?
Yes.
I've used my 802.11b/g/n capable MacBook to share an ethernet connection with my 802.11g ONLY iPod Touch.
Does the N810 see the network?
Does any other WiFi capable device in your home see the Internet Sharing SSID?
Did you give your Internet Sharing a password? Internet Sharing uses WEP for encryption, and the rules for creating the WEP Hex key from a text string password are different for Macs vs everyother WiFi device in the world. 1st try no password. If that works, then move on to using a simple 5 character password for 40/64 bit WEP, or a 13 simple password for 104/128 bit WEP.

Cable internet sharing by wifi

Hello, i'll describe my problem this way:
I have the new macbook air mid 2013.
it is connected to the internet by thunderbolt-ethernet adapter.
I share my internet connection by wifi hotspot which i've done through the sharing menu screen.
The problem:
everytime my computer goes to sleep and then i open it back - my iphone seems to be connected to the wifi hotspot but there's no actual connection to the internet. (it happens also in my ipad, and the macbook is connected and can surf the internet properly)
i have to turn off the sharing on the sharing menu, then turn off the wifi and then reestablish both of them in order to make it work again (sometimes i have to repeat this stage couple of times until it actually works).
what can i do about this?

Here's what I would try:
Open System Preferences (under the Apple logo in the Menu Bar). Choose "Energy Saver", then choose the "Power Adapter" tab on top. (I am assuming your MacBook Air is plugged in all throughout the sleeping.)
Check the box that says "Prevent computer from sleeping when display is off."
See if that helps.

Internet sharing from Wifi to Ethernet is not working after Mountain Lion upgrade

First I was having trouble just connecting these two, now I can't get the Internet sharing to work. Here's what I am trying to do: I want to share my Macbook Pro's internet connection from it's Wifi to another laptop I have connected via ethernet cable. They will ping each other now. The problem now is that the laptop won't pick up the Internet connection from the Macbook Pro, even though I have it configured exactly as I had in Snow Leopard. Nothing has changed on the laptop from before when it worked fine with Snow Leopard. But now that I updated to Mountain Lion, Internet sharing no longer works no matter what I try. I've been trying to find a solution by to no avail. Could anyone here offering some advice or a solution that will fix my problem? I've been over the basic steps over and over again, so please don't ask me to do something stupid like reboot or check the Sharing settings. They're exactly how they are meant to be, but the thing just won't work.

Ran a TCPdump on my Macbook Pro. It is recieving the ping requests, but the laptop still isn't getting replies to its pings. So something is wrong in the Macbook's configuration somewhere. I don't know where, though.

Wifi Internet Sharing over wifi!

Hi every body.
i want to share my network connection (i use wifi) on wifi!
in windows you can use "virtual network router" and you can share you network (even you use to a proxy) and this software create a wifi hotspot and other clinets cant connet to that and use your wifi connection.
in mac, in Sharing, you can share your internet connection on other ports! if use wifi you can share your intenet on Ethernet or... but not WiFi!
my question is how to create an hotspot and share my internet over a wifi when i use wifi to connect to intenet too!
Thanks!

It doesn't work like that and can't be used like that. You need a stand alone WiFi signal extender box.
Also I have never seen any Windows PC able to do that unless it has 2 WiFi cards in it. One WiFi card to receive the signal from the main router, communicate with the main router, and the other to broadcast that connection out to other WiFi devices.

Windows 7 wont connect to Lion Internet Sharing via Wifi

I have a 2011 Macbook Pro 15" with i7. I know the internet sharing feature works, because I used the wifi internet sharing with a Macbook Air and that worked fine. But when I try to connect from a Windows 7 Ultimate laptop, the connection cannot be established. I tried:
Changing the Wireless Name
Changing the encryption key
Tried no encryption key
Rebooted
Am I missing someting? Am I correct to assume that the built in internet sharing allows you to connect your devices to macbook pro as a router? I appreciate your assistance, thanks!

Same here.
I have all my machines (rather HAD) connected to the internet via a shared single connection through a 3G dongle (welcome to the countryside). I made the mistake of upgrading my machine to Lion only to realise a couple of days later that all the other machines had been starved of internet access.
Now only my main machine has access, even though according to all of my thousands worth of apple gear the green lights are on and all is ok. The Airport extreme says it's connected, its lying. The Timecapsule says its connected, its lying. The Mac mini says its connected, its actually admits there is a problem when you run the network diagnostics. Same for our macbook pro. At least the Windows machine says it's connected but no internet.
This is pathetic as apple have know there was an issue since june last year. Once more I get the feeliing Apple couldn't give a fiddlers'. Most likely greedily eyeing the forthcoming cash bonanza from the ipad 3.

IPhone - OSX 10.5.6 internet sharing via wifi has packet loss

I try to access the web on the iPhone (for testing purposes) via the bult-in internet sharing capability of my MacBookPro via WiFi. I get very slow connections and high packet loss on distances of less than a foot.
If I activate Internet sharing (eth0 - AirPort) I have packet loss of up to 80% on a Ping to the iPhone. This results in an unusable connection. In this case the iPhone gets a DHCP address from the DSL box (10.0.2.2). Pay attention to the HUGE standard deviation of the packets in case of the internet sharing!!
If anyone has config hints, I appreciate that very much. Does anyone know how to bridge en0 to Airport with WEP enabled?
Internet sharing activated:
--- 10.0.2.2 ping statistics ---
202 packets transmitted, 150 packets received, 25% packet loss
round-trip min/avg/max/stddev = 18.312/1768.538/8198.289/2201.202 ms
If I set up a Computer-Computer network with a WEP password I get no packet loss, but of course I cannot access the internet that way because there is no way in preferences to bridge the networks.
--- 169.254.246.154 ping statistics ---
443 packets transmitted, 442 packets received, 0% packet loss
round-trip min/avg/max/stddev = 1.441/1.983/57.068/2.691 ms

I accidentally found a workaround:
1. Activate internet sharing
2. Goto network preferences and use AirPort: "Create network ..."
3. Check require Password and create a C2C network
4. The Airport Icon changes from the up-arrow to the computer icon
5. Connect with the iPhone.
Packet loss is gone and sharing works fine.
BIG BUG: Procedure has to be repeated every time AirPort is turned on/off, as Internet Sharing disables/resets the airport setup!

Internet sharing unchecks wifi

Hi all,
I just purchased a MacBook Pro Retina, mid 2014 and I am trying to set up internet sharing. I've been doing this with no issue on my late 2011 MBP. I connect my new Mac via thunderbolt ethernet. I go into System Preferences-Sharing, then where it says share from I select thunderbolt ethernet, and I check the wifi option. Then I enable it by checking Internet Sharing in the left pane. I'm asked to confirm, and I do so. Then wifi turns on, but wifi unchecks.

It doesn't work like that and can't be used like that. You need a stand alone WiFi signal extender box.
Also I have never seen any Windows PC able to do that unless it has 2 WiFi cards in it. One WiFi card to receive the signal from the main router, communicate with the main router, and the other to broadcast that connection out to other WiFi devices.

IMac internet sharing failing to connect to my Blu-Ray disk player.

I have a Late 2009 iMac 27-inch. I have setup internet sharing through wifi. All of my iPods, iPads, iPhones connect just fine. But when I try to connect my Blu-Ray disk player, it gives me a timeout error. It is a Panasonic DMP-BD87P-K. I have called Panasonic, but they didn't offer to many things.

Internet Sharing is clearly working. The only options you can configure are the type of security and the channel. If changing those doesn't help, then either the device is too far away, or it's incompatible.

Internet sharing not working in lion. Bug?

Hi guys - Internet sharing of my office ethernet connection is gone. It just doesn't work anymore. I hope that if we insist flagging this, they will fix it. It was really useful at work to share my connection with mobile devices.

Seems like there is no fix yet. Whenever I turn on internet sharing, the wifi will get a self assigned ip of 169.X.X.X and no wifi devices like iphone can get an ip by connecting to this network. It was working fine prior to Lion.

Internet sharing for Vista - iPod Touch

Having mainly used Mac as my operating system, I have figured out how to simply enable internet sharing through wifi, so that my iPod Touch would have an internet connection, and allow me to browse the web.
On the other hand, I am currently on Vista as of writing and am having trouble enabling internet sharing for my iPod. It is not as simple, and I am lost. Could anyone guide me as to how this could be done?

Just do a simple Google search for "vista internet sharing"

Mavericks 10.9.2 Internet sharing prob after updgrade from 10.6.8, any solutions?

Hello World!
Here I am going to tell you my woe story which is, I finally decided to upgrade to 10.9.2 from my a little worn 10.6.8, and was very happy with a choice until stumbled upon the complete failure with establishing the Internet sharing for surrounded devices with wi-fi interfaces. Just the way it does just perfectly with 10.6.8!
Actually the network interface appears to be started but connected devices are no longer available to espablish any conection with it.
I never had deleted nothing, or changed a something tricky, I am not ageek at all.
Please help?

Same here from 10.9.1 to 10.9.2 internet sharing using WiFi won't work. I can see the little upper arrow flashing then it seems to be looking to connect over wifi instead of sharing it.

Advanced: differences in Lion internet sharing bootpd.plist?

Hi all,
I'm afraid this question is quite specific. I'm trying to get my Kindle set up using internet sharing over wifi from my macbook. I've read on these forums that to do this requires changing a tag in the bootpd.plist file created by internet sharing. This tag that needs to be edited is "reply_threshold_seconds" (the problem is that the kindle aways uses 0 in the "number of seconds since boot" field of the dhcp request packet, and the mac has a filter of 4).
I'm running Lion and in my bootpd,plist file this tag does not exist. I even tried adding it to the file with no result. I wondered if anyone could confirm whether the way OSX handles this has indeed changed with Lion; and if so it would be amazing if anyone had any advice?
Thanks a lot,
Roland

If you use your MacBook Pro as the "server" connected to the Internet. you can connect 27" 2011 iMac to your MacBook Pro via a FireWire 800 cable. (assuming your MBP has a FireWire output, I don't own one).By using Target Disk Mode (Hold down the "T" key until you see "spinning gears" on Restart or Start-up).
Your MBP will appear as a Hard Disk on your 27" display or your 27" iMac can be displayed as a Hard disc on your MBP display.
Switch the firewall off on both machines (if it was on) to see if it helps;
Try to connect using a different device to the shared connection (another computer, smartphone, iPad, etc.);
Use an open connection first (no password), before trying with WEP;
Reverse the roles of the two computers (i.e. try sharing the connection from the MBP to the iMac).
Also, more details might help (OS X version on the machines, whether you are trying to share a wired connection, installed software which might interact with the network connections, etc.)
Hope this helps in some way.

Internet sharing host name

hey guys, i changed my computer name from the original "Blank's macbook air" but when i do internet sharing my wifi network still shows up as "Lucas' macbook air" even though i changed it?
Is that just standard or did i miss something?

Hey looch555,
Thanks for the question. It sounds like you wish to change the name of the network in Internet Sharing. To do so, click “Wi-Fi Options” and change the network name from there:
OS X Mavericks: Share your Internet connection
http://support.apple.com/kb/PH13855
If you share your Internet connection using Wi-Fi, click Wi-Fi Options, then give your network a name and password.
Thanks,
Matt M.

IPad 2 wifi issues with iMac internet sharing

I have the iPad 2 [ (Wifi + 3G) ( iOS 5.1.1 (9B206) ] which connected to my 21" iMac [Mac OS X Lion 10.7.4 (11E53)] through Internet sharing seemlessly some time back.
However of late, with latest software updates on the iMac & iPad, the connection seems to work only intermittently.
The connection breaks every half or one hour, despite both the devices being in the same room.
I have tried almost all suggestions on forums like resetting your network settings on iPad, changing channels on the iMac for Internet sharing, with or without password security, resetting the firewalls on & off on the iMac, but nothing seems to work & the only way is to reset all your settings all over again.

I used Internet Sharing like this couple of times!
The situation happens is that when you share your internet over Wifi, and you password protect it, when you connect the iPad or any iDevice to that new hotspot, it happens that after selecting that hotspot, we need to turn on "Auto Join". So when the iPad gets disconnected, it gets disconnected completely and you need to connect back once again. So when you turn on "Auto Join" it will get connected automatically once again it gets disconnected maybe due to power saving or suddenly it leaves the hotspot.
