Hi wifi guru's...
I've discovered a few days ago that I created a security hole in my personal home wifi network by changing the wireless security from WEP to Mac Address filtering. I decided this changed because I'm living in the country side, with only few close neighbours and the probability of havin them sniffing or cracking into my personal network is close from zero. But I don't want them to use my internet connexion so I have obviously to secure my network. I used to do it with a 128 bits Wep encryption key but decided to change it to a Mac Address filtering for performance reason. Actually I'm using a phone/PDA (Qtek 9100) to wirelessly connect to skype at home and the little device seemed quite slow using the WEP encryption.
So I changed the config, added the mac address of my personal laptop and the pda device in the list and all worked fine. Then I decided to configure my repeater (I forgot to mention that I'm using a repeater to bounce the signal everywhere in the house). So I added the repeater's Mac address in the list of permitted addresses and everything worked fine also. Then I tried to connect with a friend's laptop to the internet, and I succeeded immediately even if the Mac address is not listed in the permitted values... It seems (and it makes sense to me) that all request passing through the repeater are permitted by the router... So the repeater's action is not really transparent since it seems to change the Original requestor's mac address by its own mac address and lets it connect...
Have you guy any advies or shall I have to go back to Wep Encryption??
Thanks for your help,
Stephane
