wifi on laptop not connecting

[#1]

Hi.  Have just changed to plus net but can't connect on my aspire one but can on my galaxy 4s and my nexus 7.... My sons aspire one does connect... Any ideas please.

Some of the Aspire One models used an Atheros chipset so it could possibly be the same problem ( and solution ) as this http://community.plus.net/forum/index.php/topic,117528.0.html

Hi rayprichard,
Have you had any joy connecting your laptop to your wireless connection?
