@atfeh 

we moved to DLINK dwr-960 works well and faster

@TP-Link 

Thanks for reply

We have sent the router to local dealer, We are waiting for a reply.

But it is too early for the router to be worn out, thus I raised this issue for your notice. not only one router has this problem but two. 

Since we bought 6 routers, We cannot guarantee now that the same will happen to other routers.

and now we cannot guarantee that local dealer will replace the router since it is out of warranty. 

Since there is manufacturing problem with the slot, what will be the solution.

Thanks
