i have a linksys router--wireless-g ADSL Gateway--model number wag54gs ver.1.1 which works ok when connected to my laptop by ethernet wire. my laptop is a Acer Travelmate 4062 LMi. However my son has a similar laptop and cannot get connected in other parts of the house or any part, without using the cable connection. My other son who has a sony laptop, and iphone, both of which can get connected with out cable connection. furthermore the range is very short .is there any way of boosting the signal so as to increase the range?
