Wireless network disapears after 1 hour

When connecting a new ASUS laptop running vista home premium to the internet
I found my wireless network, entered the key and had access to internet.
after 1 hour connection was lost and wireless router was not visible in
connection center anymore. another laptop still could connect to it. There
where other networks visible and I had no problem connecting to them (only

list or rebooting router and laptop did also not help.

So main problem is that wireless router is not visible anymore.
Can anybody give me some hints to solve this?
