RJ11 to RJ35 adapters?

[kathayes]

My home does not have ethernet ports in all of the rooms, though it does have phone lines, and someone from ATT (I use ATT for home phone service and Time Warner for internet) just told me that I could use an adapter to go from the phone port in the wall so I could connect ethernet cable into it and get an internet connection. He said that internet runs through all the phone lines the same way it does through ethernet ports in the wall.

Assuming this is correct:

1. Is there anything I need to look into when getting one of these types of adapters?
2. Can anyone recommend an adapter for this?

Thanks.

there are a lot of things that need to be in place for this to work.
you need two pairs that are not used by the phone.
the two pairs are only allowed to two of the RJ11 connecters.
the pairs need to be tidily twisted all the way to the connector where they need be punched down or you will have interference and a really bad connection.

I would rather go wireless or power ethernet.

1.) What do you mean by "two pairs" that are not used by the phone?
2.) Assuming that I have two pairs and they are twisted correctly, will using an adapter for this reach the same speeds that I would by just plugging an ethernet cable into an ethernet port in the wall?

Thanks.

a network cable has four pairs of wires.
1)
a phone only needs one pair to function and 50% of the phone jacks only have one pair connected.
you cannot share network and phone on the same pair of wires since it will most likely fry your network card as soon as your phone rings.

two pairs are needed to run a 10/100 network.
four pairs are needed to run gigabyte network.

2)
in theory yes but not faster than 10/100
