I i have 3 pack deco e4 and the main one is connected to the router in the first floor, the second one i installed to second floor and  is connected with to main one.

The problem that i am having is with the third one witch is in the third floor and it get connected to main one instead to be connected to second one,

i have disconnections with the third one because the big distance.

i did firmware update, reinstall again, access point mode and router mode, without results.

Any idea will be grateful,

Thank you.
