Ethernet over coax question

post #1 of 4
Thread Starter 
I have a coax cable running from the front house to the back house and want to connect my router to the iMac back there that serves up music and movies etc to the rest of the house. It's currently connected via wifi, but there are dropouts etc.

I've been pointed to a few different devices that can run ethernet over coax, such as this one:

http://www.netsys-direct.com/proddet...NH-310C&cat=27

there are a variety of them, and they all seem to say they have speeds in the 100mps to at the most 500 mps. My questions is this. How fast are current Airport and Ethernet speeds? I know they speak of Gigabit wireless, so does that mean 1000mps and up?

If I'm currently using wireless in this case, do you think switching to coax would slow things down a lot, or would it work ok?

thanks!

Unless you're talking about tests in Cisco labs, any router you've seen that says gigabit and wireless in the same sentence means a gigabit *wired* switch on the router coupled with 802.11* wireless. 802.11n currently scales on consumer routers to 300Mbit/s, which translates to ~80Mbps tops in real-world throughput (see http://www.smallnetbuilder.com/index...emid=&chart=82 ).

n is close enough to 100M ethernet to be comparable, but nowhere near gigabit (though at gigabit you have other limiting factors, including disk, meaning most consumers wont see better than 75% theoretical performance on their gig links). Now, whether you actually need gigabit is probably debatable, for a lot of consumers 100M wired or 802.11n is probably fine

I must have missread that bit about gigabit wireless. What I'm trying to find out is, what is the speed of n wireless and what is the speed of g wireless (I have some older Expresses on my network, so that's what I'm probably living with).

thanks!

Which wireless router are you currently using?
