Hi guys,

I'm relatively new at all this wireless router stuff, but after a few trial and errors, have been happily browsing away for a few months, no problems.

In the last week or so, a new family has moved in next door, that's when I noticed that my modem seemed to be unusually busy.

So, I went into the setup on my router (which admittedly wasn't very secure at all) and did all the things I should have done when I first installed it (change the password, enable WPA encryption, block SSID broadcast etc etc).

I enabled the MAC filter and blocked what I can only assume to be the hijacker's MAC address, as it showed in the DHCP client list (shown below)

192.168.2.5 gibbo-PC 00:18:de:d8:43:ef

I'm not called 'gibbo' and neither is any of my PCs

I also installed a piece of software called 'AirSnare' which alerts me to any unfriendly MAC addresses trying to log on.

This, eventually, brings me to my point!

I'm now getting DHCP requests from ffffffffffff on ip 255.255.255

Is this them trying to gain access still or something else?
And, what else, if anything, can I do to protect my precious bandwidth?

I know I've been a bit lax with security here!

Regards,
G Racket
