Problem with modem after shutting lid

[Guest sambrea]

Hi,

 

I have recently encountered a problem with my system, where after shutting

the lid of my laptop to rest for a period of time because i have to go away,

it no longer is able to encounter my family's wireless network, so i have to

shut the computer completely off and restart it. It's a pain in the neck and

has just recently started doing this, starting after 3 or 4 shuts, but now

it's down to one. It's just plain annoying because I might have things I'm

doing online that I don't want to lose the place of. Any help would be

gratly appreciated.
