Wired & Wireless won't work at the same time

100r1 · 05-17-2009, 07:11 PM

Just built 2 barebones ASUS motherboard with builtin Lan (10/100) ethernet cards. Running XP sev. pack 3 replacing 2 10 year old computers that ran 98 that had LAN (wired) network access but no internet of any configuration.

These computers are on a small business network with IP range 192.1.2.xx that DOES NOT have internet thru the LAN (cat6 Hard wire). computers are Hard wired to a hub this network is for file/printer sharing and access to a data base for running a software called Tribute from a server. These computers have to use static IP addresses and can not use DHCP (dumb hub and server has no DHCP capabilities)

Our internet is wireless on IP range 192.168.1.X using USB wireless NIC's with DHCP (have to use DHCP on the wirless side to accomdate other hardware & users)

Problem is we can not run the wired and wireless at the same time (wireless will not work when the lan card in the computers a enabeled) and if we are running on the wired LAN the wireless side from time to time disconnects the wired connection to the server which leaves open partitions on the server and the server has to be reset.

As long as we are not running both at the same time everything works fine it just breaks when we try and run wired and wireless at the same time and it's a PITA to disable and enable the LAN card every time we need to go from running server application/printers/ etc. to accessing the internet (web access or email).

I have checked for hardware conflicts and IRQ conflicts and there are none.

I have a feeling it is in the way we have setup the network using the Microsoft Network setup wizard that comes with XP.

Any ideas ? any tutorials on how to do what we are trying to do without confusion on all the other network possibilities I have seen on the various MS and other forums ?

Thanks

A network diagram would be useful here. You're talking about two subnets and wired and wireless, so I'm assuming here are some routers WAPs, etc involved here as well.

Seperate, both networks fine. When trying to run BOTH lan(intranet) and wireless (internet) at the same time they both do not work. Usually the LAN (itranet) works but the Wireless (internet) does not pull up webpages. plus the LAN (intranet) connection will break if after a few minutes and if I am logged into the Mainserver it will disconnect and leave a open partition on the server.

I have no idea what that diagram is supposed to illustrate, but it failed.

You seem to have a terrible kludge there. What are the two ISP connections supposed to accomplish? Do you have two ISP connections?

I'd suggest something like a dual-WAN router, but I still don't really understand what this configuration is, so that may not be appropriate.

100r1 · 05-22-2009, 07:30 AM

NO, there is only one (1) ISP (internet service provider)

ISP is through Wireless

The 2 networks are:

NETWORK #1:

Private Network for small business (Intranet) LAN IP: 192.1.2.xx
(this is for printer, filer sharing & access to Mainserver only)
-> NO INTERNET on this network <-
* Static IP Address only *

NETWORK #2:
Wireless Internet service from ISP Using DHCP IP address current of 192.168.1.143
-> this is how we access the world wide web <-

* Basically, I'm connection to my small business network with a cat6 hard wired cable and my internet service provider by wireless. EACH with it's own IP address.

** I have had it working in the past on a LAPTOP (Sony Viao PCG-K37)
but that laptop as originally configured no longer exist to look at
settings.

This is the IP that your ISP gives you? That is a private address, not a public one. Or is this the address that is on one of the computers?

So let me see if i'm understanding this correctly, you have Network#1 which is wired and setup for its own use and has no internet. You have Network #2 which is wireless and your ISP is wireless. The ISP connects to a wireless router which then connects to the ASUS desktop that has a wireless card in it. Then you have a cable running from that desktop to connect to network #1 hub to give them internet access.

So what you are trying to do is share out an internet connection through that one computer. Did i get this right?

Network #1 Private address (No internet)
Network #2 wireless ISP wireless DHCP IP address from router and ISP
Provider

Yes Cable Cat6 runs from Computer to LAN Network #1 (private)

NO on internet sharing accross the LAN (Wired side)

*each computer access the Internet on it's own through wireless (each with it's own USB wireless NIC / adapter)

100r1 · 05-22-2009, 08:24 AM

Another way to look at this is:

I have a laptop that has internet through the built-in wireless card, WHEN I am at the office I want to connect to the office network for printer/file sharing and to enter data ion the server.

the office has no internet on it's own. but since I have wireless internet on my laptop I will access the internet wireless and access the office network wired. I just have to do both at the same time without breaking either connection.

**lorjack** · 05-22-2009, 08:31 AM

Oh OK, so each computer has two NICs one wired and one wireless on network#1. And when Network #1 tries to connect to the internet, the internet is unavailable. So you have to disable the wireless NICs in order for it to work. What is the configuration for the wireless NICs? Are they using DHCP or Statically assigned addresses?

Wired is NIC #1
Wireless is NIC #2

NIC #1 does not try/connect to the internet ONLY connects to office
network for Printer/file sharing and access to mainframe / server

NIC #2 connects to internt only (wireless)

When NIC #2 (wireless) tries to connect to the internet it is un-available
and YES to connect I have to Disable NIC #1 (OR un-plug the WIRED cable)

NIC #1 uses static IP address (192.1.2.13)

NIC #2 uses DHCP

>>>>> Could there be a problem due to that both NIC's are set to use AUTOMATIC METRIC under TCP/IP properties ? ore does that have nothing to do with it since each NIC is going to a different destination (office network VS world wide web) ?
