Using Windows XP with Qwest DSL modem and Linksys switch. Was having trouble getting laptop to access network, so while troubleshooting, unplugged switch power cord and restarted dsl modem. Now laptop works, plugged back in switch but terrified about wireless security. I will not be able to get back to location until weekend and am very worried about security for wireless network. Does the switch even have security? Does the dsl modem? Exactly what can happen if someone is using an unsecured wireless signal? How can anyone get to information on your computer through an unsecured wireless network, even if you have firewalls on your computers? Is WEP the best to use or is WPA? If anyone can answer these questions fully, my world would brighten tremendously.
