Yesterday was the installation of major Windows updates which took a while on my laptop. That one is still under XP Pro. So, once the updates were completed, a reboot was necessary. Then, after the reboot, everything was OK. This morning, I realized my main PC was no longer able to see my laptop. When I checked my laptop, I see it has a low Signal Strenght ranging between 11 to 12 Mbps. This laptop is wireless and just about two feet away from my wireless router. Anyone would know what could be in effect here?
