Abstract

A method for a wireless router to adjust a state of a wireless network provided by the wireless router, includes: monitoring whether the state of the wireless network satisfies an adjusting condition of adjusting the state of the wireless network; when the state of the wireless network satisfies the adjusting condition, sending an adjusting prompt to a wireless terminal, the adjusting prompt being configured to ask for user permission to adjust the state of the wireless network; and if the wireless router receives from the wireless terminal an acceptance instruction to accept the adjusting, adjusting the state of the wireless network.

First claim

What is claimed is:

1. A method for a wireless router to adjust a state of a wireless network provided by the wireless router, comprising:
monitoring whether the state of the wireless network satisfies an adjusting condition of adjusting the state of the wireless network;
when the state of the wireless network satisfies the adjusting condition, sending an adjusting prompt to a wireless terminal, the adjusting prompt being configured to ask for user permission to adjust the state of the wireless network; and
if the wireless router receives from the wireless terminal an acceptance instruction to accept the adjusting, adjusting the state of the wireless network,
wherein the adjusting of the state of the wireless network comprises: when the wireless router receives from the wireless terminal an acceptance instruction to accept the adjusting, switching a first communication channel currently used to a second communication channel, and reestablishing a connection with the wireless terminal on the second communication channel.

2. The method according to claim 1 , wherein the monitoring comprises:
monitoring whether a channel quality of the first communication channel of the wireless network currently used to communicate with the wireless terminal is lower than a preset channel quality.

3. The method according to claim 1 , wherein the monitoring comprises:
monitoring whether a signal intensity of a signal received from the wireless terminal is lower than a preset signal intensity.

4. The method according to claim 1 , wherein the monitoring comprises:
monitoring whether a signal intensity of a signal transmitted by the wireless router is larger than a minimum signal intensity required by a space where the wireless router is located.

5. The method according to claim 3 , wherein the adjusting of the state of the wireless network comprises:
increasing a signal intensity of a signal transmitted by the wireless router to a preset value.

6. The method according to claim 4 , wherein the adjusting of the state of the wireless network comprises:
decreasing the signal intensity of the signal transmitted by the wireless router, to be equal to or larger than the minimum signal intensity.

7. The method according to claim 1 , wherein the sending of the adjusting prompt comprises:
sending the adjusting prompt including at least one of state information of the wireless network and adjusting result information.

8. A wireless network device for providing a wireless network, comprising:
a processor; and
a memory for storing instructions executable by the processor,
wherein the processor is configured to:
monitor whether a state of the wireless network satisfies an adjusting condition of adjusting the state of the wireless network;
when the state of the wireless network satisfies the adjusting condition, send an adjusting prompt to a wireless terminal, the adjusting prompt being configured to ask for user permission to adjust the state of the wireless network; and
if the wireless network device receives from the wireless terminal an acceptance instruction to accept the adjusting, adjust the state of the wireless network,
wherein, in adjusting the state of the wireless network, the processor is further configured to: when the processor receives from the wireless terminal the acceptance instruction to accept the adjusting, switch a first communication channel currently used to a second communication channel, and reestablish a connection with the wireless terminal on the second communication channel.

9. The wireless network device according to claim 8 , wherein the processor is further configured to:
monitor whether a channel quality of the first communication channel of the wireless network currently used to communicate with the wireless terminal is lower than a preset channel quality.

10. The wireless network device according to claim 8 , wherein the processor is further configured to:
monitor whether a signal intensity of a signal received from the wireless terminal is lower than a preset signal intensity.

11. The wireless network device according to claim 8 , wherein the processor is further configured to:
monitor whether a signal intensity of a signal transmitted by the wireless router is larger than a minimum signal intensity required by a space where the wireless network device is located.

12. The wireless network device according to claim 10 , wherein the processor is further configured to:
increase a signal intensity of a signal transmitted by the wireless network device to a preset value.

13. The wireless network device according to claim 11 , wherein the processor is further configured to:
decrease the signal intensity of the signal transmitted by the wireless network device, to be equal to or larger than the minimum signal intensity.

14. The wireless network device according to claim 8 , wherein the processor is further configured to:
send the adjusting prompt including at least one of state information of the wireless network and adjusting result information.

15. A non-transitory storage medium having stored therein instructions that, when executed by one or more processors of a wireless router providing a wireless network, cause the wireless router to perform:
monitoring whether a state of the wireless network satisfies an adjusting condition of adjusting the state of the wireless network;
when the state of the wireless network satisfies the adjusting condition, sending an adjusting prompt to a wireless terminal, the adjusting prompt being configured to ask for user permission to adjust the state of the wireless network; and
if the wireless router receives from the wireless terminal an acceptance instruction to accept the adjusting, adjusting the state of the wireless network,
wherein the adjusting of the state of the wireless network comprises: when the wireless router receives from the wireless terminal an acceptance instruction to accept the adjusting, switching a first communication channel currently used to a second communication channel, and reestablishing a connection with the wireless terminal on the second communication channel.
