Wireless problemsI have a similar problem with my laptop. I have a Fujitsu-Siemens Lifebook, one that has been great over the past year for college, etc. However, my wireless internet connection suddenly went off the other day with no warning, with the modem showing that there was no local network and the laptop showing no available connection.

First thing to do - check wireless is turned on. It sounds basic, but sometimes the switch can get knocked, meaning that the laptop won't recieve any wireless signal. If this doesn't work, play around with the settings for a while - if you're running Windows you can go to 'network connection' in Control Panel and right-click on your wireless connection; go to 'repair' and the repair wizard will go through it to try and fix it. Make sure both the wireless switch on your laptop is turned on, and that your modem is turned on too.

If this doesn't work, go to your modem's setup page (usually a web page - the address will be in the manual) and choose a different wireless channel - 0, 6 and 11 are the only non-overlapping channels. You may want to adjust your wireless signal power to make sure you have enough signal. You might also want to run a diagnostic on your modem to see if it is running properly. Some modems will display on the setup page which computers are active. See if yours comes up.

If this still doesn't work, you may want to go to an internet cafe or other wireless hotspot to check whether it is your modem which is At Fault. If you get a signal and can connect, then it may well be the modem at fault. Check at some other locations just to be sure. If not, it sounds like the wireless card has a problem. If it is an internal wireless card, you might want to take it back to the manufacturer for repair. If it is an external wireless adapter, you may just want to replace the card or adapter to see if this helps.

There are numerous reasons for your laptop not to pick up your wireless connection. Check the following and see if they solve your problem. 0.5 Check if your wireless router is switched ON! 1. Check if your laptop has a wireless card in it (old models might not have). 2. Check whether your wireless network is hidden. If it is just set it to visible. 3. Check that you are in the range of the wireless network. 4. Check the network configuration of your laptop. 5. Check if the wireless adapter on your laptop is not disabled. 6. If any of these don't help call a technician :).
