Internet sharing over wireless

Didn't see anyone post this but is anyone else having problems with Internet Sharing over wireless?
Trying to have the macbook connect to the iMac over wireless and use the iMac's wired internet connection. On the iMac, the Airport card is on, and in network preferences, internet sharing is turned on. However, the options for sharing over wireless is grayed out and I can't get into those options to customize it. On the macbook, it doesn't see it in the available networks list to connect.
Am I missing something? Do I need to "create a network" on the imac now? I didn't have to do this in 10.4.10

After much consternation and countless trials I finally have everything back up and working. Here is what I did finally to get it to work. (Note that I am not a network configuration expert - I am only reporting exactly how I have it configured and it works without complaint).
1. I trashed my \Library\Preferences\System Preferences folder and restarted my Mac since I had updated from 10.4 and I wanted to start from a fresh set of preferences. ( I backed up that folder separately)
2. I opened the Network Preference pane and configured my Ethernet connection (connected to my external AirPort Express which I am using as a wireless router to my other computers) as follows:
-Configure: Using DHCP
-IP Address: 192.168.0.197
-Subnet Mask: 255.255.255.0
-Router: 192.168.0.1
DNS Server: 192.168.0.1 (grayed out and so I am not sure what this means)
I set these settings by clicking on the Advanced button.
Under the TCP/IP tab I had chosen:
- Configure IPv4: Using DHCP
(This set the IPv4 Address, Subnet mask and Router)
- Configure IPv6: Automatically
3. On the Sharing Preference pane, I configured the following:
-Share your connection from: Novatel Wireless EXPD (because I have a 3G wireless connection; otherwise I would have chosen the standard Internet connection)
-To computers using: "Ethernet"
And then I turned on the Internet Sharing Service and confirmed in the pop-up dialog that I wanted to share my Internet connection.
4. Using Airport Utility, I configured the Airport Express by first clicking the Internet button to show the Internet Connection page and set the following:
- Connect Using: Ethernet
- Configure IPv4: Manually
- IP Address: 192.168.0.179
- Subnet Mask: 255.255.255.0
- Router Address: 192.168.0.1
- DNS Server: 192.168.0.1
- Ethernet Wan Port: Automatic (Default)
- Connection Sharing: Off (Bridge)
I also configured my Base Station and Wireless with names and Passwords.
I then clicked Update in AirPort Utility and after it restarted everything magically worked!
I think that the problem lay with my original IPv4 settings where I had chosen DHCP rather than Manually hoping that everything would automatically be set as it had worked previously. The clue was that on my MacBook Pro I noticed that the DHCP was not enabled when connected to the AirPort Express. Even my iPod Touch is now connected to the Internet!
If anyone can explain all of this I would appreciate it.

Poor internet connection over wireless router

We have a modem and wireless router setup in our house. The PC Laptop connects wirelessly and gets a fair internet speed. The Mac Laptop on wireless however gets a very very poor internet speed over the network. Any ideas why this is so?
The speed increases a bit when I hook the mac laptop directly up to the modem via cable, but the wireless is the problem...
thx

lots of questions need answers.
name of provider?
the speed you signed for?
cable or DSL or ?
modem is older or not?
firmware update required?
router model?
firmware update required?
at least start here.

Internet sharing over ethernet

My iMac here is sharing my dialup internet connection over ethernet.
my iBook is set to Configure IPv4 using DHCP but it's getting an IP of 192.168.2.12 and the subnet 255.255.255.0 and the Router 192.168.2.1.
But the iMac isn't even connected to the internet yet? o.O it's a crossover cable directly between the two computers so there is no other computer on the network. Airport is off on the laptop and I don't own a base station yet.

The computer gets its IP address from the router not from the Internet. If you have Internet Sharing turned on, then your iMac is acting as a router and providing an IP address to the laptop via the Ethernet cable connection.

Printer/Internet sharing over ethernet not working

Due to unsolvable problems with Airport and 10.5.2, I've decided to set up an ethernet network between my Mac Pro and MacBook. I have an ethernet cable going from the ethernet 2 port on my MP to the MacBook. I am able to establish a file sharing connection, so I know that the cable is working.
However, I cannot get printer sharing or Internet sharing to work.
I have enabled printer sharing in Print & Fax preferences, and selected the USB printers I want to share. But when I go to Print & Fax preferences on my MacBook, although I do see my printer when I attempt to add it the preferred driver does not show up and it selects "generic postscript" instead. This is completely strange, because when I go through the same process when the MacBook is connected to my Airport network (when it isn't dropped out), I am able to add the printer with the correct driver without a problem.
As far as Internet sharing goes, there's nothing happening at all. On the MacBook when I open Network preferences it says "Built-in ethernet isn't connected". I don't know what I'm supposed to do to get this going. I already have enabled Internet Sharing on the Mac Pro ("share built-in ethernet 1 connection with computers connected to ethernet 2"), but I don't know what to do beyond that.
Do I need a switch?

sure, there are workarounds. I was trying not to spend any money!
Mostly I am curious what caused it to stop working.
Thanks for the input!!

Trouble sharing over wireless or IP over FireWire

I've been trying to share a new MacBook running Leopard my new iMac running Tiger and its driving me nuts.
I only have one network port in my office but we do have corporate wireless. After turning on file sharing on the MacBook and connecting to the wireless network, I can ping it OK but it refuses to show the login window when I try to connect from my iMac via the Go menu. Any ideas on this issue?
I just discovered IP over Firewire but don't know if I'm doing the right thing as nothing is happening. I've connected the two macs via FireWire, in the MacBook I've selected Networks > Built-in FireWire [location automatic] using DHCP.
It gives that wonderfully cryptic message "Built-in FireWire has a self-assigned IP address and may not be able to connect". The IP address starts with 169.254.
The questions are: where does it get its DHCP address from? Do I access it via the Go menu? Should I be able to ping it from my iMac? Should it be able to connect to the Internet? Scant info out there on the net (or its well hidden).
Thanks

MBP C2D internet sharing over Airport

I have DSL connected to my MBP C2D over ethernet and want share this connection over the MBP Airport so other computers can wirelessly access the internet. While other computers can see and connect to the shared Airport connection on the MBP, however there is no internet available. I suspect this is because the MBP C2D is using 802.11N frequency and my other computers are G. How can I force the MBP to transmit in G?
Thanks

Whatever the problem is, it is certainly not related to the G or N standard.
Do you have "Personal Web Sharing" enabled under System Preferences-Sharing-Services? If not - try it.
Under System Preferences - Sharing - Internet review the "Airport Options...", some network names (containing special characters) and encryption settings (40-bit WEP with 5 char password or 128-bit WEP with 13 char password are normally most compatible) can cause problems. On some Windows systems you will need to set the Gateway and DNS IP addresses for the connection manually to point to the shared computer's IP address for Internet functionality to work flawlessly).

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.

File and Print Sharing over wireless

I have the following hardware:
MBP - Brand spanking new kickin' machine running 10.4.x
G4-400 - old but still doing nicely running 10.3.9
PC running XP
MBP has the extreme card built in
G4-400 has a third party wireless card that's been working for 2 years
PC has a netgear wireless card
Router is a netgear WR814v2 wireless B
Facts: Before I bought the MBP last week, I could access files between my G4 and PC fine over my network and access the web at the same time. When I connected the MBP to the network, I could surf. When i tried to turn on filesharing, it works for a short time, but then knocks the network offline. The model still shows a connection and my router still broadcasts and the wireless cards all get the signal, but nothing connects.
To troubleshoot the issues, this is what I've done so far:
When it went down, the first thing I did was turn file and print sharing off on both of the macs, restarted and tried the connection. Again, model still shows logged in, but no connection. Then i plugged the PC into the ethernet port on the router to get a wired line. Still no connection on the PC. Next, I shut down the macs, disabled the wireless on the PC and restarted the PC. Still no connection through the ethernet port even though the model and router still show all signs good. Also, through all this, I couldn't log into the router's IP address once I was wired to it. Next I shut down the router and modem, waited, then turned on the modem, waited for it to cycle to ready, then turned on the router. The modem showed that it was connected, then the router showed wireless broadcasting. Then I had my connection to the web back.
I then went back to square one and tried file sharing again and again everything locked up. It seems like some how the file sharing between the macs is confusing the router. I tried fixing the ip address that the router assigns to each machine, but that didn't solve the problem. I'm at my knowledge's end. What am I doing wrong here? My goal is to share files at least between the macs and print through the G4 which has a USB and a Firewire printer attached. I'd like to accomplish the filesharing while still being able to access the web. But for some reason, I can the file sharing up and running for a short time, but then everything falls apart and locks up.
MBP Mac OS X (10.4.6) G4-400 and PC also on network

I figured out the networking mess - the secret, don't follow the instructions on the apple site - listen only to everyone in this discussion. I kept following the instructions to turn on appletalk and that's what was tying everything up. When I just use the sharing preference panel without going into the network preference panel, all is good in the world. I can now view all three computers with their shared folders(enhanced by sharepoint for a couple of external drives) and also print from all machines to the printers hooked up to the G4.

Poor internet speed over wireless

We just signed up for a new ADSL2+ plan, and received a wireless router along with it (an Open Networks iConnect Access 624W), which came pre-configured for our ISP (Internode).
My housemate (who has a 17" iMac G5), had no problems finding the router and is getting around 1.5MB down a second. I, on the other hand am getting anywhere from 130kB a second, down to 0. It's slow, and very very patchy. And it's getting worse. (this morning, I struggled to download a 700kb file).
I tried to re-setup the airport settings multiple times to no avail. I've checked to see I've run all software updates (I have).
It's weird, it's not like it isn't connecting. I can at least bring up something, albiet very slowly, and I can see the other iMac via bonjour. I just can't get the same internet performance.
The router is placed pretty much dead centre between the two iMacs too (just in the hall between the rooms). Can't be more than 3m away from the computer.
Is there anything I can do to narrow down the issue?
Could there be something wrong with my Airport Extreme card?
Thanks in advance

Welcome to the discussions!
It certainly is possible that there is a hardware problem, but it is more likely that it is in the settings somewhere. Have you checked to see that the settings in the two Macs match? I would make sure that Airport is listed first in the connections and also be sure to have IPv6 turned off. Those are two things that I have found can make a difference in the performance.

Losing internet connection over wireless

Hi
I got my iMac last Friday and since then I have been having two very annoying wireless bugs.
1. My Mac does not connect to my wireless network automatically on start-up.
2. I will be surfing away happily when I will suddenly loss all internet access, I’m still connected to my wireless network I still have a decent 5 or 6 bar connection but I just can access the internet. It generally comes back after 30 to 40 seconds but twice I have had to restart to get the connection back.
Does anyone have any advice on this.
I’m with Eircom broadband and use a netopia wireless router with WEP security. I could really use some help.

sure

Force sleep without disabling Internet Sharing

Hi,
Now that Mountain Lion includes WPA2 Personal encryption for Internet Sharing over Wireless, I've decided to try using it instead of my Airport Extreme Base Station to shre my internet access with my iPhone and notebook. One of the benefits I hoped to gain was the ability to simply put my Mac mini to sleep to turn off my network when, for example, sleeping or at work. That way I reduce opportunity for unauthorized attempts at access and save energy.
The only flaw appears to be that the Mac mini doesn't want to sleep when Internet Sharing is on. I've tried using the menu item and the keystroke (Option-Command-Eject), but neither will send the Mac to sleep. To get around this, I could simply turn off Internet Sharing when I don't need it; but:
1) This means launching System Preferences and authenticating to the Sharing pane, which is cumbersome and slow
2) Internet Sharing forgets my wifi settings when it's disabled
Does anyone know of a way to force my Mac to sleep even when Internet Sharing is enabled?

Hello Scotch,
I'm working on my MBP 15' late 2011. I use it at school (Wifi network) and at home (Ethernet cable).
I also like to turn on the internet sharing for my iphone as my room is to far from our hotspot @ home... (**** you concrete walls)
But i'm also one of the jerks that abuses his mac by almost never shutting it down and just closing the lid (same as putting it to sleep).
i found out that when i close the lid with the ethernet plugged in (& sharing turned on), my macbook does not sleep. This can be handy, but can be annoying for noises at night.
If you turn off the airport on your computer, or remove the wired internet connection, the internet sharing will stop without changing your pref's.
when you turn it back on, or plug the cable back in; the sharing starts again with the same settings automaticly.
It's not 100% what you're asking for, but it does the job in 2 clicks...
i hope it helped.
Greetings,
Wouter, Belgium.

Printer sharing across internet sharing

I hope I don't confuse everyone with this.
I have three computers—an iMac running Snow Leopard, an iMac running Lion, and a Mini running Leopard. The SL iMac has a printer plugged into it. The other two computers are across the house from it.
Those two computers are next to each other. The Lion iMac is connected to the Internet via WiFi. The Mini, which does not have wireless, is connected to the Internet via Internet Sharing over an ethernet cable to the Lion iMac.
Now here's the problem. I can print from the Lion iMac through printer sharing across to the SL iMac. However, I can't figure out how to print from the Mini. It won't find the SL iMac's printer. Enabling printer sharing on the Lion iMac lets the Mini see it as a 'printer,' but it won't print across to the SL iMac.
So with this setup, is it possible to print to the SL iMac from the wireless-less Mini?
Just to ward off possible non-workable solutions, rearranging the computers is not feasable right now. It is also not possible to connect the Mini directly to the internet via ethernet. My cable modem is actually in a near-inaccessable part of the house due to that being where the only cable plug is. I have a Time Capsule attached to it, which broadcasts my wireless signal that the WiFi computers can pick up. And no, I can't connect the printer to the Time Capsule—believe me, I tried. I don't want to have to start buying long cables and drilling holes if there's a simpler solution.
Thanks in advance.

If I switch to the discussed set up (Airport Extreme N router), will adding an AX in between at 15 feet help bridge the link between the G5's Airport extreme card and the living room's AX?
Yes. But I still think you should verify if Wi-Fi interference is the cause of your poor signal only 30' away from the AX before going out and purchase anything. Remember, you will tradeoff bandwidth performance for signal strength. With audio, this can be a negative factor.
If you can get a hold of a laptop, I suggest downloading a copy of iStumbler. Use iStumbler's Inspector feature (select Edit > Inspector from iStumbler's menu) to determine the Signal-to-Noise Ratio (SNR) at different points around your house, by performing a simple RF site survey. Within the Inspector, note the values for "signal" & "noise" at these locations. Start with the laptop near the AX, note the readings, and then, choose the locations between the AX and, finally, where you have the G5.
SNR is the signal level (in dBm) minus the noise level (in dBm). For example, a signal level of -53dBm measured near an access point and typical noise level of -90dBm yields a SNR of 37dB, a healthy value for wireless LANs.
The SNR, as measured from the laptop, decreases as the range to the base station increases because of applicable free space loss. Also an increase in RF interference from microwave ovens and cordless phones, which increases the noise level, also decreases SNR.
SNR Guideline
o 40dB+ SNR = Excellent signal
o 25dB to 40dB SNR = Very good signal
o 15dB to 25dB SNR = Low signal
o 10dB to 15dB SNR = Very low signal
o 5dB to 10dB SNR = No signal
If the SNR is 20dB+ at each of these locations, then you should be getting reasonable performance from your AirPort. If less, either try to locate the source of the Wi-Fi interference or try relocating the base station or the G5 until they are within a 20dB SNR range.

XP can't connect to iMac-based AirPort for Internet Sharing

(I apologize if there's already an answer to my issue out there somewhere; I promise that I searched for it before posting)
Hello!
I have an iMac running Tiger (and connected to the internet via ethernet -> cable modem), and I want to use it as a hub for encrypted Internet Sharing. I have two other machines, an older iMac and a WinXP laptop. As you might expect, I have no problem whatsoever setting up the network and getting the old iMac to see it, connect, and so on. The XP machine can see the network, and, when encryption is off, can connect to it, but I really want to run encryption.
I'm sure I'm not the first person to run into this problem, and I have found a couple of websites that discuss it -- however, I can't seem to make it work. Does anyone out there in forum land know of a step-by-step tutorial that would cover setting up encrypted Internet Sharing (over AirPort) on an iMac so that another iMac and an XP machine can connect? Any guidance you can offer would be most welcome.
Thanks in advance,
Dieter

Just to give a bit of an update, I chatted with Apple support, and in essence they told me that I had to take this up with the manufacturer of my XP laptop's wireless card -- understandable, given that my old iMac works just fine on the network (so the problem really isn't on the Mac end of things).
I tried using the information at http://www.macosxhints.com/article.php?story=20030803030354585, but no dice, unfortunately; maybe that will work for someone else, however.
I also found out something new -- I thought my XP laptop could connect to my AirPort network when encryption was off, but I was wrong. Instead, it just says "trying to connect," but nothing ever happens. But I CAN use the XP box to connect to other wireless networks in the neighborhood (shh, don't tell). So it looks like there's a deeper issue.
Please -- I know that someone out there has an answer; I really need to be able to make this work.
Thanks again,
Dieter

Internet sharing possible with PowerBook running OS 10.4?

My ethernet/wireless DSL router handles my internet connection. My PowerBook G4 OS 10.4 connects to my wireless router via AirPort.
My Mac Pro OS 10.5 networks automatically with the PowerBook via built-in ethernet. File sharing works fine between the two. I enabled internet sharing over ethernet on the PowerBook, and the Mac Pro can't connect to the internet. Obviously I'm missing something?
TIA for any help.

The reason is geographical. I'm trying not to run ethernet cable thru the floor to the upstairs room where the router lives, and the wireless doesn't reach the basement room where the Mac Pro lives. The PowerBook has a spot downstairs where it can find the wireless, and the ethernet cable from it can reach the Mac Pro. That's my current set up, but if it won't work, I'll have to think again.

Iogear GBU211 and internet sharing with missing sync

I have an iogear GBU211 bluetooth to usb adapter and it has been behaving strangely. I use the connection between my TT3 and the computer keeps dropping and it cannot complete a full sync over bluetooth. I would also like to take advantage of internet sharing over the palm. I decided to give missing sync a try. I was finally able to perform a hotsync (as long as I didn't try to install anything to the palm), but the real problem hits when I try to use internet sharing. I get a kernel panic everytime. Here is the snippet from the panic.log file.

I would (i think) rather use the iogear as it has a better range and I don't want to go and buy the d-link. I dislike that apple is trying to force me to use the d-link adapter. Does anyone know of a fix for the iogear problem?

I do understand what you're saying Michael, it isn't exactly profitable to offer broad range support, but at the same time, a little broader would be a nice thing. In the case of the IOGear module, it's packaging did have the os X logo on it (if memory serves me correctly) and it did state it will work in Mac os as well. With that in mind, one would think that either or both IOGear and Apple would know about this and make sure that it does work, or, barring that, Apple should have IOGear pull their compatibility statement off of their packaging. As a consumer, if a product I purchase states that it will work with my machine, I would expect it to do so with minimal headaches.
In any case, as for my main problem (no wise cracks please), I caved and picked up the D-Link. I had a friend with a pee cee who needed a bluetooth adapter, so, for a "fair" price, I was able to go grab the D-Link.
With the exception of it's shorter range than the IOGear BT adapter, it has worked flawlessly (so far).
