wireless network questions

Hi, I'm very new to linux but I have had a home win network for a few years. I just bought a laptop a few months ago. And I just got wlan working on it, so I bought a wireless router and replaced it with the one that was standing as a switch. It should just work, and it did for a vile. But then I found out I couldn't get access to the rest of my computers, couldn't even ping them. The only thing working was my internet connection and then that stop working to. I think the wireless signals might be interfering with my internet connection that is also wireless. And Internet starts working again for a vile when I reset the adsl box that is connected to my router (not the wireless one) and the antenna outside. So here are my questions:

Can I have both the network card and the wireless card active at the same time?

Way can't I connect to my other computers when it goes trough one switch and one router to go online but do not notice anything else connected to the boxes? Do I need to change setting in the switch?

Can one wireless setup interfere with and other? Like in this case wireless adsl connected to wireless lan?

Oh, and where do I set up dsn in debian? I think I'm just using setting left over from a dhcp lookup, however dsn settings is only nessesary for the router or am I way off?

I will proably figure this out on my own EVENTUALLY but if anyone can point me in the right direction it would proably save me some time. Besides if keep fixing everything myself I am never going to be a part of this forum You see I have been homeless since the kazaalite-forum died tragic....

Distro dependent..

To answer your questions:

1. YES! It is possible, but the problem is - why? It takes extra configuration because 2 devices can't be running the same *proccesses at the same time*. If you set it so a card is a slave to Firefox, and the other to a game, then it should work.

2. No. You need to update a file called "hosts", it should be *normally* located in /etc/hosts. You have to list ALL of the network addressess of the computers. Another issue may be Samba (SMB). You need the Samba client to connect to Windows machines.

3. It really depends the manufacturers and frequencies. You must configure the routers / switches to transmit on seperate channels. From there, you must set up the ESSID (using ifconfig), for each device. This will allow it to auto-connect so you don't always have to scan for networks. As long as the channel is different you can have 2 cards on 2 networks.

4. /etc/resolv.conf I believe is where you put DNS addresses. Although I am not fully sure (I just use DHCP with Debian machines), I think thats where it should go.

I would, as always, suggest Google to find answers as well if you need a far more in-depth explaination :-)
