hi! I installed a WRT54G2 to a friend of mine some months ago, all fine until yesterday. He called me and said that wi-fi was out of order. I went to him and I noticed that: SSID changed from linksys to PC-Home_User_Network (or something like that) Passphrase changed. Security was WPA. So, I changed the wi-fi settings like this: SSID: LINKSYS phassphrase: 10+ char long, alphanumeric (not randomic like 23h2j5he2b5h245 but more simple) and some special chars. Security: WPA2+AES. Tested with my netbook and all seemed fine. today he called me: the problem is still present. Is is possible that the central button on the router (the WPS one) can reset wi-fi settings if pushed? Suggestions? Is it a security break action? I can not to deactivate DHCP server and/or activate MAC filtering: the users are "tech-unfriendly".
