A little question, please reply folks as I am really worried. All the 3 antenna sockets at the back of my R7000 have very little (slight) amount of up and down play (Loose Movement) when trying to move with a little effort but right and left there is none. If you try to feel the toughness of the socket and try with very little force to move it up and down u feel its not that tight, even with the antenna attached you can just hold the attached end of the antenna and try. IS IT NORMAL as my old Linksys WRT54G wifi G router has no play at all?
