yes thx

ok could you right click on Realtek RTL8187S Wireless LAN PCIE Network Adaptor and select uninstall , click ok and reboot the computer ,
once it restarts you should see it "FIND NEW HARDWARE " and it should then reinstall it
is there a button or slide which turns on and off the wifi ?

slide on the left hand side
did not say reinstalling but looked under crontol panel and it is reinstalled

hi
when you move the slide is there a light or indicator that tells you the wireless is on or off ?

no.so theres no real way of knowing if switch is working right?

ok
do you have any icons on the bottom right hand side that would be a program which is related to wireless, this may look like an antenna with signal lines around it or maybe a small computer type icon which when you hovver the mouse over it it may say something relating to wireless or realtek
?
do you have a program called hotstart buttons or something similar on it ?

there is a red "x"over the computer icon which means it is not connected to the internet.i do not have a hotstart program or anything else
