Can I connect RG6 to BNC and get Internet?

[Omer David Sivan]

Hey everyone!
I am trying to get Internet to my room, and I wanted to do it trough the RG6 cable i already have there.
Is it possible to connect the RG6 cable to a BNC female connector and then take a BNC to RJ-45 ethernet adaptor with this one http://?
or it's not even related to Internet/RG6 cable.
EDIT:
I dont want to use the Powerline, we tried that already.. and I know about the MoCA but they're too expensive.

Thanks for the help!

OMG, this brings me back. In the olden days, generation 1 ethernet ran on coax cable at the then blazing speed of 1 mbit/s, then CAT cables appeared and they use baluns as signal adapters between the 2 cabling types.

I dunno man, try it out. But if it works in any satisfactory manner, you will have put the MoCA folks out of business. Don't call me.

I'm pretty sure this won't work. You're trying to use a BNC to RJ-45 adapter to carry ethernet over RG6 (coax). These adapters are designed for the opposite purpose - to allow you to carry RG6 signals (usually video) over ethernet cable. If you're putting together cabling for an event, it's a lot easier to rig up a single ethernet cable instead of 4 individual coax cables. So these adapters are popular for temporary setups for concerts, conventions, etc.

Since the video signal is usually analog, the adapters are designed with a balun to separate the video signal into the two ethernet twisted pairs. If you try to use the adapter the other way around (ethernet over coax), it'll result in the ethernet signal being unbalanced over the coax run. It can pick up RF interference (any which gets through the coax shielding anyway), which will probably make the ethernet signal useless when reconstructed.

Also, your link doesn't work but from your description it sounds like you've only got a single length of RG6. That definitely won't work. All the adapter does in that case is carry that coax signal over a single twisted pair in the ethernet cable. The other 3 pairs are unused. For this to even have a chance of working the other way around, you need a balun which connects a single ethernet cable to 2 RG6 cables (for 100bT ethernet), or 4 RG6 cables (for gigabit ethernet).

No that adapter will not work for ethernet. Are you using your RG6 cable for anything else? If you are not, or if you are using it for Satellite TV, you can use 2 DECA adapters. They are a MOCA technology but MUCH cheaper than MOCA.

Very promising.

It could work with pair of 10BaseT/10Base2 Ethernet hubs (you will most likely find them in some thrift store, eBay etc), with re-crimping of that cable' connectors. Your speed will be limited to 10Mbit/s, though, and you want to make sure that this RG6 cable you've found is a single piece.
