For the last few weeks i haven't always been able to connect to the net,on the few occassions i have no prob! but why can't i always get in? had this notebook for 14 months without a prob. only started about 6 weeks ago in that time i have only been able to access the web about 5 times one of them today. switch on and do everything as normal but just won't connect, any guesses?

First i would try moving the switch that is located on the front of the netbook to the right. Once the switch has been moved the wireless networking icon will appear on the screen indicating that it has been enabled.If this doesn't help my next step would be to remove and recreate the wireless network connection by doing the following:

1. Click on Start, Settings, Control Panel
2. Open Network Connections
3. Right-click the wireless network connection, and click Properties
4. Click the Wireless Networks tab
5. Under Preferred networks, click the wireless network, and then click Remove
6. Click View Wireless Networks
7. Under Network Tasks, click Refresh Network List
8. Under Choose a wireless network, click the wireless network to which you want to connect, and then click Connect

1. Go to Control Panel, System, click the Hardware tab and select Device Manager.
2. Click the + next to Network Adapters and double click on the Atheros wireless Network Adapter.
3. Click on the Advanced tab, select Power Save Mode from the list on the left.
4. Change the Value on the right to Off.
   The default setting is Maximum, which may cause issues similar to those described.

1. Click on Start, Settings, Control Panel
2. Open Network Connections
3. Right-click your wireless network connection, and click Properties
4. Click the Wireless Networks tab
5. Under Preferred networks, click the wireless network, and click Properties
6. Click the Authentication tab, click to clear the "Enable IEEE 802.1X authentication for this network" check box, and then click OK twice if this doesnt help the computer may need service.
