Wireless problem

I have windows7 installed, ona a Gameforce notebock with a Realtek RTL8187B Wireless 802.11b/g 54Mbps Network adapter, and the thing is mi conection keeps falling and the only way that i can reconect again is to restart. I have already tryed changing mi router and its the same, other's nootebooks conected to mi network doesn't do the same, their conectoin does not fall so often and wen it falls thei can reconet automaticaly without having to reboot.
Can anione help me on this?
