Hp keep lan and wlan both on

It sounds like you have a virtual wife that needs to be connected to the internet.

I guess you are talking about your wife's computer and you like to share the internet connection through her computer; therefore, you will need to activate ICS (Internet Connection Sharing) on your wife's computer using the LAN card. In other words you are converting your wife's computer into a router. You will need to setup the ICS before you connect your computer.

the reason the wifi is disconnecting is that windows can only use one network card at a time but it can use two if you are enabling ICS.

i'm sorry. i don't know why. But wife should be wifi. My mistake. God spare me. i don't need a women for ever  
So situation: Wifi online with ics on it. wired nic got his fixed ip and subnet 192.168.0.1 / 255.255.255.0 so far, so good. But as discribed above. My wifi nic disconnects from the moment i plug in the copper cable in the wired nic.
The pc connected to it get's a correct ip 192.168.0.20 & same subnet (dhcp and dns up and running)
So we are linked together but both pc's doesn't have internet anymore.

Disconnect copper cable. Wifi comes alive again ... So this ics method works fine for 2 copper nics. but not for wifi+copper. That's my problem.

You say XP can't have 2 nic's online @ the same time whitout ics. Think again. XP can! Same router, same switch.
different IP's from the same subnet. That is on copper wiring. Not copper + wifi. We have servers running XP with 2 nic's online. (i know not a good id) but it works. trust me.

So what i need is a way to explain XP not to disconnect wifi when i plug in the wired nic. It has something to do with saving energy .... But i can't find a way to force wifi online always. No disconnections for what reason it might find .... Any id's? I have a probook 6550b from HP.

On linux it might be a little bit more difficult but al distro's i tested CAN do this. No prob @ all.
Unfortunately i must use XP @ work. I would have chosen a different OS if it was up to me  

Btw you can talk in ict terms to me. I will understand you. No need to explain in noob language  

Thanks !!

Windows prioritizes the NICs.

see if it make a difference to set the wifi as the main NIC.
