dserban 0 Report post Posted June 30, 2007 Here's my setup:My PC connects to my Internet facing wireless router via a USB-pluggable wireless NIC, the IP address of which is 192.168.1.2 (netmask 255.255.255.0).The IP address of my router's LAN port is 192.168.1.1.The NIC which is embedded in the motherboard has remained disabled so far.Everything works OK, but I recently got a hold of a crossover cable, and I started using it to connect a laptop to my PC.So I enabled the embedded NIC on the PC and gave it an IP address of 192.168.2.2 (netmask 255.255.255.0, default gateway 192.168.2.2).The laptop's IP address is 192.168.2.1.My only objective is to able to exchange files between my PC and my laptop.I do not want to connect my laptop to the internet, either directly or indirectly.And here comes my problem:After setting up the (crossover cable) connection between the two, I tried going out to the internet again on my PC, and failed.I tried using tracert to troubleshoot what's going on, and my gut feeling is that as soon as I enabled the embedded NIC on the PC, it seems to think "Oh, this is my new Internet, let me send all the requests from the browser to this new default gateway 192.168.2.2".One solution that comes to my mind is to use static routes. I know what they are in theory, but I don't know how to issue the commands.If anyone has experience using static routes in Windows XP, I would appreciate a few pointers in the right direction.Also, if there is a better / more efficient / more elegant solution, I would very much like to hear it.

faulty.lee 0 Report post Posted June 30, 2007 There's 3 things you can try, non of them belongs to static route.1. Set a permanent DNS in the DNS setting of wireless NIC and set the gateway of both NIC to your router's IP2. Bridge the connection of both your NIC. You can select the 2 NIC, then right click, Bridge Connection. That way, you only need to set 1 IP address for the bridged connection. So, both your NIC will have the same IP, and that should help fix the issue, also it will automatically routes internet on your laptop(if i'm not mistaken, as i have tried the same thing before, quite sometime back)3. Setup internet sharing, to share your internet to your laptop. That way, windows might figure out which NIC is actually connected to the internet.Let me know if any of that works. I seldom play with networking lately, will be good to refresh my theory a bit.Good Luck Share this post Link to post Share on other sites

Wutske is right, the error you did was changing the default gateway when adding your second network.Basically, when you have a computer correctly connected to the worldwide network, like your PC which had a correct default gateway and a DNS, the standard thing to do is to leave that working part continue working.So, when you add a second network (that is what you do when you activate your second NIC adapter) you should not remove your default gateway, replacing the correctly working one by a non-working default gateway.The default gateway is your wireless router, your wireless router must remain your default gateway.So, when you manually add other NIC's to this computer, please feel free to give them private IP addresses, this is correct, simply write down nothing in the default gateway field, leave this field blank, and the new network will start working correctly without disturbing you old network which will continue working as usual.By the way, don't be confused having this problem : this kind of problem is the problem I am currently experiencing at office : my collegues continuously change their default gateways, and then start complaining because their network does not work any more !

iGuest 3 Report post Posted June 4, 2008 Can you help me with this? How Do I Create Static Routes In Windows Xp?  I have this scenario:  - 1 public IP address - 1 cable modem - 1 router (4 ports) - 4 computers with private addresses connected to the router  Everything works flawlessly. I want to connect a laptop with a wireless network card to the internet. My router is not wireless, and all it's 4 ports are used. To be able to connect the laptop, I bought a wireless network card and put it in one of the computers. I want to use this computer (Windows XP Professional) as a router/gateway for the wireless network. At the moment, the card is installed properly, as far as I can see in Windows. I created a new wireless network named xyz, which I can see from the laptop, but, but the laptop is unable to browse the internet. The packet's path should be like this, I think: it should come from my isp, through the modem, router, pc's wired network card, pc's wireless network card, laptop.  Please tell me how should I set the IP addresses for the wireless network.

My router is not wireless, and all it's 4 ports are used.To be able to connect the laptop, I bought a wireless network card and put it in one of the computers. I want to use this computer (Windows XP Professional) as a router/gateway for the wireless network. At the moment, the card is installed properly, as far as I can see in Windows. I created a new wireless network named xyz, which I can see from the laptop, but, but the laptop is unable to browse the internet.The packet's path should be like this, I think: it should come from my isp, through the modem, router, pc's wired network card, pc's wireless network card, laptop.Please tell me how should I set the IP addresses for the wireless network.

docduke 0 Report post Posted July 2, 2008 To answer the original question about static addresses, in both Linux and Windows, the key files are "hosts" and "lmhosts". In Linux, they are usually in /etc/. In Windows 2000, they are in \WINNT\system32\drivers\etc\. In Windows, the lmhosts file defines the decimal addresses corresponding to given names, for example: 192.168.1.11 alpha #PRE192.168.1.12 beta #PRE192.168.1.13 gamma #PRE The "#PRE" tag instructs Windows to load this table before trying to resolve any addresses. If you use such static assignments, you need to have this lmhosts file in EACH of your computers, since your DHCP won't know these addresses. In Linux, there are additional options on these lines that vary with different Linux flavors.The hosts file is where you can define external translations (outside your lan), and also where you can "blackhole" websites. For example if you wish to identify Fred's computer and also prevent your computer from visiting http://www.spammaker.com/, insert lines that read:64.22.1.1 fred127.0.0.1 spammaker.com That instructs your computer to look at 64.22.1.1 for http://forums.xisto.com/no_longer_exists/ and only inside itself for any web address that contains "spammaker.com".
