Share internet connection from PC to Mac

[MDGM]

Hi all,

 

After about 18 hours of work and several panic attacks I have managed to set up Windows 7 and OSX dual boot on my Dell studio XPS16 laptop. I have one problem however... There are currently no drivers for my laptop's wireless card. The work around I will use is connecting my dell laptop to my netbook via ethernet and bridge my netbook's ethernet and wireless network adapters. When running windows 7 on my dell laptop I can connect to the bridged network and get online. I then copied the network settings and set them up exactly the same on my mac os:

 

ip 192.168.1.14

subnet 255.255.255.0

gateway 192.168.1.1

dns 192.168.1.1

 

But I get no internet connection. If I try to use the same ip as my netbook it says "ip in use by" + netbookMacCode, so it has some connectivity. The diagnosis utility says I can connect to everything up until isp and internet.

 

Can anybody tell me what I'm doing wrong?

 

Thanks,

Max.

Well, my classes weren't this detailed, but I will offer some thoughts. First quoting,

 

"For me, the solution was a crossover cable. I have a laptop with Windows 7. I have a connection to a wifi AP. I have a desktop that needs to connect to the wifi but doesn't have a wifi card.

1. I first connect to the wifi.

2. Then in control panel -> network connections, I right-click on my WiFi adapter (not the virtual wifi port) and then Properties, and then click on the sharing tab. I put a checkmark in "Allow other network users to connect through this computer's internet connection". Under Home Networking Connection drop-down, I chose "Local Area Connection" which is my laptop's LAN NIC.

3. I unchecked Allow other computers to control...

4. OK

5. Make sure the LAN NIC you will use for connecting to the other computer has any static IP configurations removed and set to DHCP.

6. Make sure the LAN NIC on the desktop you will connect to is set to DHCP also.

7. Connect a crossover cable from the laptop to the Desktop.

8. If it's windows vista or 7, then it should connect and present you with the "Home network, Public Network, Work Network." Choose appropriately.

You should now be connected! If the desktop doesn't automatically connect, you may want to "Diagnose" or "Repair" the LAN connection.

Good luck!"

 

Ok, you don't need a crossover cable. And I don't know what OS is on your Netbook. These instructions work for Windows Internet Connection Sharing (ICS). So as I understand it, the Netbook has the working wifi connection. If you put the Netbook on the same network, I think it's called WORKGROUP, and enable ICS, SL should be able to share the Netbook (Windows) Internet connection. The way I think that works is called DHCP, which means IP addresses are automatically assigned. So if your gateway is 192.168.1.1 with ip 192.168.1.14, that ip would be given to your netbook connection. Your ip should be something like 192.168.1.15, which seems like the numbering is starting out sort of high. And I have seen them change. But anyway, my idea is that the ip addresses should be assigned by DHCP and not static. I got an IT degree but this wasn't my specialty and I've never used a bridged network. If you have a wireless router (so not crossover), your netbook can receive signals from it. Your laptop likely has a cable ethernet port. You can enable your Dell's onboard ethernet and plug that cable into the router (both transmissions can work). SL is much more likely to have a working onboard En kext than a Wifi one for your Dell.

EDIT: I have seen some guides which say you do need a crossover nic cable which would mean that you would need an onboard En port on the netbook. http://www.sevenforums.com/tutorials/76617...ing-enable.html This says you can use ICS and wirelessly connect to the internet from the host computer but you need a cable to share between computers.

Hi, thanks for your reply.

 

My netbook has windows 7 pro and laptop has windows 7 ultimate and leopard OS X.

 

Like i said, the bridge works fine when booted into windows but not when booted into leopard os x.

 

When I tried to follow those 8 steps I had no "sharing" tab on the properties window of my wireless network connection.

 

I should also mention that i installed ethernet kexts that were recommended for my specific laptop and straight after the ethernet configuration box popped up so afaik the adapter is working properly.

 

Last thing, I'm on the top floor of our house so have no wired access to the router (and my wireless card dosnt work on the mac os) which is why I need to bridge and use my netbooks wireless.

Update: Removed networks from bridge and can now share. Networrks shared and DHCP settings applied. Netbook can connect to internet. Laptop now now gets about 5% of the loading bar accross and stops. New auto applied internet settings:

 

Laptop (osx):

ip 192.168.137.38

subnet 255.255.255.0

router: 192.168.137.1

 

netbook (win7 pro):

Wireless network:

ip: 192.168.1.91 (preferred)

subnet: 255.255.255.0

gateway & dns: 192.168.1.1 (router ip)

 

ethernet network:

ip: 169.254.251.54 (preferred)

subnet 255.255.255.0

 

Not sure why the ethernet ip is preffered as it shjould be set to dhcpo.

 

Sorry for rush and bad typing, am using netbook keyboard and late for lecture!!

 

Thanks

I haven't worked on this for some time so I'm trying to remember troubleshooting steps.

The Netbook has Windows pro and is wireless on the third floor. How did you obtain those

ip addresses? As I recall, from a command prompt one types ipconfig /all <enter> with both computers turned on. Then next see if you can ping Laptop (osx): ip 192.168.137.38 from the netbook. I think it's better to find a written guide for troubleshooting this. I also seem to remember Printer and File sharing had to be enabled but that was with Windows XP, not sure about Win 7.

 

"Last thing, I'm on the top floor of our house so have no wired access to the router (and my wireless card dosnt work on the mac os) which is why I need to bridge and use my netbooks wireless.:"

 

If the computers are on different floors, even if the mac wireless worked, the signal would have to traverse at least one floor from the router to reach both computers. I have a Linksys router which is both wireless and has cable ports. Yours? Why can't you put the router on the same floor as the mac laptop and plug in the wired cable there while sending the wireless signal to the third floor? Like I say, if the Mac wireless were working, you would still have to send a wireless signal to a different floor than the router for one of the two computers. Your Dell laptop is very likely to have an onboard ethernet port (cable) and they are easier to get working than wireless (and faster).

turns out i had network card drivers for a slightly different model installed which is most likely why it didnt work which kind amakes this thread obsolete until i get that issue sorted. the setup i talked about above should generally work on a dual boot mac with decent drivers. thanks for your help
