ICS - Internet connection sharing does not

I build two computers with Win7 Ultimate and need to share a modem on a wired network connection. I have got the file sharing to work between the two machines and followed all the instructions concerning the ICS, but still not get the no host machine to connect to the Internet. I chose the option on the host computer to allow machines on the network to control the connection, and of course, when I plug the cord of connection linking the two, the host dials upward. However no program on the computer no host can actually communicate.

You are in the right place.  The host of cable connecting network address IPv4 is not what it should be, which indicates that ICS is not configured correctly.

While remaining in 'Control network and Internet\Network connections', right click on the connection dial-up, and then click Properties > sharing .  If Internet connection sharing is checked, uncheck it and click OK.  Then go back and put a check mark in this box to re-enable Internet connection sharing.  If a box appears asking you to select a private network connection, select the connection of cable system in the menu.

  • Internet connection sharing does not work anymore

    I have used Windows Vista Home Premium for 2 years now on my laptop. Internet connection sharing enabled to connect to the internet via my wireless adapter and allowed me to share my internet connection through the ethernet port. He worked for more than a year. All of a sudden 4 months ago Windows Vista doesn't let me share the internet connection more. When I go to networking and sharing Center, click on "Manage network connections" and it shows that my "Wireless Network Connection" is always set to share. So after reading several forums, I clicked on wireless network connections and click right properties. Then I clicked on the sharing tab, to make sure that "Allow other network users to connect through this computer's Internet connection" has been verified and that it is. After that, Windows Vista will not always share the internet. Someone suggested that I double check the IP version 4 and 6 on the wireless and Ethernet connection were defined on IP addresses obtain automatically, and they are. The computer still will not share the internet connection! I even took the manufacturer in the view of portable and made sure my cable modem Simulator wasn't bad. I took it to a computer store and we checked the crossover cable. Everything is fine! What else can I try?

    Obtain an IP address automatically is the wrong setting on the Ethernet connection.  To return to the sharing tab and unshare the wireless connection.  Close all windows network, and then open them and re - share the wireless connection.  Who must configure IPv4 for the Ethernet connection properties for:

    IP address: 192.168.0.1
    Subnet mask: 255.255.255.0
    Default gateway: no
    DNS server: no

  • ICS: Internet connection sharing ERROR while allowing IP.

    Hi all

    My "Netgear" router gives the IP Address of the gateway 192.168.0.1 and my laptop is connected via a wireless connection. When I turn on my connection sharing wireless internet connection, windows xp tells me with the message below:

    "When Internet connection sharing is enabled, your LAN adapter will be on use the 192.168.0.1 IP address." Your computer may lose connectivity with other computers on your network. If these other computers have static IP addresses, you must set them to obtain their IP addresses automatically.
    "Are you sure you want to enable Internet connection sharing?"

    When I press 'Yes', it gives me an error:

    "An error occurred while Internet connection sharing was being enabled.

    Internet connection sharing cannot be enabled.
    A LAN connection is already configured with the IP address that is required for automatic IP addressing.

    My question is, if we can configure ICS service to activate other windows of the IP ADDRESS is required to apply?

    Thanks in advance for your help...

    I'm sorry, but ICS is completely inflexible and does not change its LAN IP address.

    The settings that you found are for something else: allowing unsolicited Internet connection requests to pass through the firewall on the ICS computer to a client computer.

    Change the address LAN IP of the router.  It is easy to do and will solve the problem.

  • internet connection wifi does not work after entering safe mode

    It works when I connect it to the router with cable, I had this problem before & there was a command typed in cmd that solved but I can't remember it, any help?

    Interesting... If you have booted without failure then you restarted in normal mode and your wireless settings no longer work?

    UH... Well the first thing I would do is to disable and reactivate my wireless card.  The second thing I would do is check I get an IP address on my wireless network, this is done in the command line (cmd) by typing "ipconfig".  If you get an IP address then you know that your router works on the dhcp protocol, but to confirm I would ping the router, which will be your entry door, which is usually something like "ping 192.168.1.1".  If you do not have an IP address, you should try to renew and see if you can buy a... "ipconfig / renew".

    In addition, you will need to check that you are actually connected to a wireless network, it should appear in your software wireless windows, or you proprietary wireless NETWORK card software.

    Hello.

    With Windows 7, I want to share the network connection Wi - Fi with Bluetooth through PAN (Personal Area Network).

    When there are several connections in addition to Bluetooth after opening "Share" tab, I see these connections in the "Home Networking connection" list, but there is no Bluetooth. Then, when there is no connection in addition to Bluetooth which I can share with, there is no tab "share."

    Also, when I tried to fix this problem manually, other questions are raised:

  • By using internet connection sharing

    I'm having a problem using ICS.  It used to work perfectly, but then I had to reinstall vista and use my restore disks, and it has not worked since.  That's what I'm trying to do.  I'm taking a wireless internet signal coming from my router and it sends through my LAN port for the computer of my son, who does not have a receiver wireless on his computer.  This used to work properly, but don't work no more... That's what I've done so far:

    I turned on ICS on my wireless connection.  I checked all the services I want to be able to have the connection (http, ftp, telnet, etc.).  I turned "detect settings ip automatically' on my son's computer.  I have a crossover cable from my computer to my son (that's what I used before too).  I don't know what happens wrong... someone has any ideas?  Please help :)

  • Internet connection sharing cannot be enabled.

    Greetings. I noticed a lot of posts about a similar situation, but I don't seem to find the answer that works for me. The skinny: using Windows 7. I connected to XBox live through ICS with my laptop. Hotel has wireless and I connected to it. Then, I followed the instructions and my wireless for sharing of the value. From there on, I wired XBox laptop w/ethernet cable and XBox settings manually configured as IP address, subnet, gateway, & DNS address mask. It was working fine the first day. During the next two days, connection was super slow... but it still worked. The problem does not seem to come from the hotel's Wi - Fi connection. It was the laptop for XBox it seemed. So I did some reading more and got more stupid than usual. I tried to 'Bridge' of the LAN and wireless connections to see if I could get better results. I'm not too good sense of course so I didn't know if it would work. There can be no. This is why I removed the two bridge connections and even removed the icon of "Bridge". I tried to go back to the original configuration that has worked and that's when I started getting the "connection sharing Internet can not be activated. A LAN connection is already configured with the IP address that is required for automatic IP addressing"message. So now, when I check the share my wireless, I have that message and it won't share. I'm lost! I tried "ipconfig \all. I tried "netsh winsock reset." Nothing seems to work. I don't know if I'm doing something of out of order which does not allow local network setting. I mean... what must be plugged in the ethernet cable, or even not at all, and when it is, that the parameters of the Xbox is? I even put the XBox failing to see network settings if I could start to this end. If it was not obvious, I'm still able to access the internet wireless and wired. This is something crazy and so far, none of my smart friends have been able to help! Thanks in advance for any of yours. As I said, I'm really not good with this stuff so if you have answers, please show idiot as I am a fool proof. See you soon!  Jim C
