I can't get my Acer Laptop to set up Linksys wireless internet

Try the following first power cycle the netbook (take off your battery and unplug the unit then hit the power button a couple of times b4 putting power to the netbook). After that power up the machine and try to connect.Also go into the power settings and set mt wireless card to off on the "power save mode".The "power safe mode" options are explained further below.Hope this works for you
