The power is between -65 to -70. I also tried to test one by sitting just right next to it. I don't think it has anything with obstacle and stuff. Router is from Huawei. And reaver says:
[P] WPS Manufacturer: Ralink Technology, Corp.
[P] WPS Model Name: Ralink Wireless Access Point
[P] WPS Model Number: RT2860
Wash indicates that WPS is not locked. Super confused. Please, help?
