Agreed that WEP is only marginally better than wide open. However I am |
45 |
using an old Linksys ethernet/wireless bridge that does not support |
46 |
WPA. Plus this is my small home network on property that is not that |
47 |
close to others. Add to that MAC filtering (again, not hard to crack) |
48 |
and I feel that the likelihood of someone seeking me out and cracking my |
49 |
network is unlikely. And even if someone did, what are they going to |
50 |
get? They'd still have to crack each system on my net before finding my |
51 |
MP3s and family photos. |

For me, WEP isn't wrong. Just an educated choice based upon my hardware |
57 |
capability and security needs. Yours may be different. |
