I am trying to join two buildings with an Ethernet cable. Distance is aprox 60 meters (180ft). On one end, I have a modem connected to a Linksys WRT54G router, and on the new building, I receive the ethernet cable in a Dlink Switch (DES-1008D) , I distribute ethernet in 6 outlets and send one cable down stairs (10 meters (30 feet)) away from the switch and receive it in another dlink switch, again a (DES-1008D). If I place a laptop at the receiving end of the ethernet cable that comes from the main building, it receives the signal (internet) ok, when I try each one of the outlets in the top floor, I receive internet ok, although the farthest I am from the switch, the longer it takes to connect. When I go down stairs, I can't connect, or it connects intermitently. I have tested all sections with a tester and they work ok. My gut feeling is that I have taken the length of the ethernet cables to the distance limit, and because of the amount of connections it has to go through, I loose some extra signal.
1st Question: Do the swithces act as range extenders amplifying the ethernet signal, or they just provide a pass through not amplifying at all.
2nd Question: Are there any signal amplifyers I might use to solve this problem?
3rd Question: Is there any other solution I might look at, or other tests I should perform?\
Because of the layout of the building it is not possible to use a wifi link.
