I have one on the first floor and one on the second floor (tsg 1-2 and tsg2-4). As long as I sit on the silver bench on the other side of the silver book, the signal speed is not bad. I was shocked when I got the password. It was so long and complicated. It is not easy for me to get this. If you understand, please contact qq 1594027633, and be careful. I guarantee my life span of 50 years! And everyone can only give one. No one can say for sure! ! Not even family! !
