Hi,
I am using two Lan Card one for mail and other for Broadband.
I am using DSL-502T ADSL 2+ Router for Internet.
And using Ethernet card 8329 for accessing map driver on file server and other LAN Data.

But when I am going to use this two simultaneously, the Browser shows no server found.
Then I have to disable Ethernet Lan for Internet and when I want to use my mapped drive on server. I have to disable Internet Lan or USB Connection of ADSL.

What to do.
While using ethernet card for internet for DSL-502T only one is working, either internet or LAN.It wants static ip address.
But while using USB cable for internet for DSL-502T for some time internet works.But after few minutes. It shows same no server found
Then I have to restart the browser.then again it works for some time and sometime not.
Triband USB accept IP address from DHCP .

What else setting can be done to work on both simultaneously.
I intalled NLB but that doesn't work too.
Please help.

It sounds like you are configured with two gateway addresses when both connections are made. Please run an IPCONFIG /ALL and paste the contents to a post.

This is what you asked for.

Gateway 192.168.1.1 is for Broadband

Gateway 192.168.3.254 is for LAN

Of course the gateway is different but this type of connection works on other PC

chuckhole please help!!

chuckhole please help!!!!!!

Sorry. I have been working non-stop for about 16 hours a day supporting a major project in another country so the hours I have been working have not been easy on this old fart.

I am reading over your post and will get right back with you.

Thanks chuckhole

The problem with your PC is that you ALWAYS have two gateway (router) addresses. You need to remove one and provide an exclusion for your other network.

Since you only have ONE router, we will perform the second route on your PC.

Open the TCP/IP configuration for your 192.168.3.143 network card and REMOVE the gateway address.

Then, open a command prompt and type the following (replace ^ with a space and {Enter} is the Enter key):

ROUTE^ADD^-P^192.168.3.0^MASK^255.255.255.0^192.168.3.254 {Enter}

You should be able to browse the Internet without issue and then when you have a request for your other network, it will be directed to your other network card. The -P switch makes it a persistent route so that it will come back after a reboot.

To see your changes, type:

ROUTE^PRINT {Enter}

Shall I have to put that gateway again in TCP/IP configuration of 192.168.3.143.
Or keep it as it is.
One more thing is happening when I fired route for 192.168.3.254 my default gateway also automatically changes.

Does default gateway matter in route?

Yes. The Default Gateway matters in a route. Routes must be accurate.

Review your settings you have poseted. The network that has DHCP enabled has to be treated as your primary network and the other network that is using a static address needs to be treated as a secondary network. All of the addressing for your Primary network will be assigned by your DHCP server. You will not have control over these addresses and what is assigned (including your gateway address).

REMOVE the gateway address from your secondary network configuration with the fixed IP addresses (192.168.3.254 gateway).

What is happening is that your computer must ALWAYS try to perform routing with ONLY one router - 192.168.1.1 in this case.

If your WAN address on your 192.168.3.254 router has an address for the 192.168.1.0/24 network then it knows of the other network. Your 192.168.1.1 router must be made aware if this network with a static route to 192.168.3.0/24 with 192.168.3.254 as the gateway.

OR, you must add the static route to the PC as described above. There can be ONLY one default gateway address on your PC or it gets confused as to which one to use ALL THE TIME. The other gatway must be the Exception and the Static Route in your router or PC is what provides the exception to the rule. It is used ONLY when a request to the other network is made.

For computers that reside in the secondary network that need to access the primary network for Internet access, the best method is to use the static route in your primary router to complete the return route.
