I want to do a demo on the wifi security. So, I have one Wifi router and two client.
I configured my router without security (OPN) and with a MAC filter.
One of the two client is connected to the router and sends infinite ping on the router.
So, with the other client, I capture the legetimate MAC adress with airodump and I change my MAC adress with macchanger.
After this, I am well connected on the router and I can ping google.com without problems.
But when I try to access a web page (http), It does not work.
I do not understand why? If I have a conflict with the MAC adress, normally I can not ping with both.
