Solution to intermittent break line problem when using Intel 5100 wireless network card

Symptom :

There is some intermittent break line problem when using wireless network.

There are many reasons that lead to this problem, but incompatibility in the PSPM model may be the main reason. PSPM(Power Save Polling Mode)is a wireless network energy-saving technology, which is used to extend the using-time of the notebook battery. The technology needs support from both the wireless router and the wireless network card of the notebook. The 5100 model wireless network cards of Intel can support PSPM. But some wireless routers do not support PSPM, thus it may lead to the problem.

SOLUTION:

1. Open the start menu, select "Control Panel".
2. Double click "Network Connections".
