I have a wireless network which I set up using my Linksys router. I made the network secure using WPA2. A couple of days later (or maybe sooner, I'm not sure), I noticed the connection was unsecured. I went in and again I set up again the WPA2 security. I then noticed again, pretty soon thereafter, my network is unsecured. What could be happening? I'm not sure what factors could cause this to happen. Old router? Infected PC? I don't know what to look for... any advice is helpful. Thank you in advance.
My computer are 2 laptops, one Windows 7, the other XP (home). I have a broadband internet connection and then a Linksys router. Neither laptops are wired to the modem- they both connect wirelessly to the network.
