Abstract
A wireless access point receives a set of invalid passwords from at least one wireless device attempting to connect to a network through the wireless access point. The wireless access point reduces RF signal power in response to receiving the set of invalid passwords.
Claims9
A method for securing a network by a wireless access point, the method comprising:
- receiving a first set of invalid passwords from at least one wireless device, the at least one wireless device attempting authentication with the wireless access point with passwords, the first set of invalid passwords received with a RF signal at a first power level, the first power level associated with a first RF signal range, the RF signal adjusts power level range around the wireless access point that a wireless device is able to communicate with the wireless access point using a wireless connection;
- and
- reducing power of the RF signal to a second power level in response to receiving the first set of invalid passwords, the second power level associated with a second RF signal range, the second range smaller than the first RF signal range.
A method comprising:
- receiving, at a wireless access point device, a first password from a wireless device attempting authentication with the wireless access point with passwords, the first password received with a RF signal of the wireless access point at a first power level, the first power level producing a first RF signal range, the RF signal adjusts power level range around the wireless access point that a wireless device is able to communicate with the wireless access point using a wireless connection;
- determining the first password is invalid;
- determining, in response to the determining the first password is invalid, a particular number of invalid passwords have been received within a specified time period;
- reducing power of the RF signal from the first power level to a second power level in response to the determining the particular number of invalid passwords have been received within the specified time period, the second power level producing a second RF signal range, the second RF signal range smaller than the first RF signal range;
- receiving a second invalid password from the at least one wireless device, the second password received with the RF signal at the second power level;
- determining the second password is invalid;
- and
- disabling the RF signal in response to the determining the second password is invalid.
