1. I have been trying to connect to / with you in vain.
2. If you connect this device to / with your computer / TV you can....
3. Are you connected to / with foreign channels?
4. To get a good job you need to be connected to / with someone ...
5. Meet Jeff, he is connected to / with many schools.
According to the Cobuild dictionary :
A. connect something to something = join one end of X to one end of Y : Connect the hose pipe to the tap
and your example 2. But personally I'd also use with
. On Google I found this, which actually uses both in exactly the same context - Handhelds connect with USB On-the-Go - ZDNet UKA variation of USB will enable handhelds and other devices to connect directly to printers or to each other
B. Connect something with something = make it possible to pass from X to Y : We're putting in another flight to connect Brussels directly with Manchester.
Again, personally I'd also use to
. Google came up with Arrive SAO PAULO and connect with flight to CUIABA
and KLM flights to Amsterdam connect to most of the rest of Europe
C.to be connected with something/someone = to be related to or involved with something : Good health is connected with diet.
and your examples 4+5. Once more I'd also use to
and Google agrees : A Brazilian man killed by police in south London was unconnected to Thursday's attacks police confirm.
as well as Writers and Books connected with Essex
That leaves your examples 1 and 3 - which I don't think I'd ever say. I'd use :
1. get in touch with you
or contact you
. For me, to connect with someone
means to be on the same wavelength
or to relate mental
ly to someone. Example from Google : Gordon Brown - We must listen, learn and connect with voters.
But also on Google I found : Networking – how to meet and connect with the people you need to know
which is ambiguous. Is it my meaning or similar to your example 1?
3. Can you get/receive foreign channels?
So it seems to me that the two prepositions are actually used more or less interchangeably.
Hope that helps.
