RG6U two modems? RG6 switch?

[ShadyBeings]

Just moved to new house, no switch in the house yet but we got most of the coax ports hooked up with internet/cable. Where they originally placed the modem and router did not have an RJ45 wall socket for me to run it back to where the future switch will go but its a nice spot for wifi in our house.

 

Can I just buy a separate modem and put one up in a more convenient spot? Also would using a coax splitter/switch and using one end for ethernet and the other for cable mess it up?

You can't run 2 modems on one internet connection on consumer services, certainly not having them appear as the same IP. Each will have its own unique MAC address, and thus will have to have their own unique IP addresses. Most ISP consumer accounts don't support more than one modem. Because the MAC will have to be registered with your provider, you can't just switch between devices at random.

Not like it used to be huh can't just have your own modem.

 

Alright so two modems isn't an option, what about running a splitter out of one wall coaxial and split it between TV and internet?

You can buy your own modem, but you can't run 2 at once, on the same account. Been that way a long time. In some cases, people have signed up for 2 accounts at the same location/address, and even done some elaborate duplexing to gain more bandwidth, but that's expensive and not that effective in the modern era.

 

You can run a coax splitter block, so long as it says it is bi-directional - some aren't as a protection from RF noise and 'crosstalk' on older analog applications. Newer splitters are nearly all bi-directional. Since TV and internet occupy different subcarriers on the cable line, they run concurrently and you can have a TV and modem hooked to the same wall jack without serious issues.

First of all 1 modem per account. If you get a second modem it will be treated as second service, requiring a second bill. 

 

Coax ax doesn’t have a switch, it uses Spliters. Also make sure you don’t put too many spliters between the main line coming in and your modem. Each splitter in line will cause loss on the signal. 

 

Also if you need to wire up a switch in another location and don’t have Ethernet ran I suggest looking in to MoCA adapters. Essentially they allow you to use the same coax as your internet provider and get a wired connection to areas without Ethernet. Setup is a little more involved, but I’ve heard of speeds up to 800mbps, maybe even more with the newer Moca standard.

Those moca things look dope, I'm going to have to read into them a little bit more and make sure that simply using a splitter won't be the better solution for me, but definitely interesting! Just at a price of $160 for a pair splitter seems like the better way to go.

 

Do y'all know if I have to match the frequency or anything? I'll make sure the bidirectional thing is correct. Don't think we talked much about coax networking back in college, all we got taught was the different RJ standards so I'm trying to find out as much as I can now

Spliters are no issue with Moca and yes they communicate bi directional. Frequency wise they use 1-1.5 GHz, outside what the cable company would normalize use. Shit companies like Comcast use Moca for whole home DVR. 

 

The only issue you you need to look out for is this. The run between adapters can’t be more than 300 ft. You need a Moca filter on the main cable line coming in to your home. This is prevent the signal from leaving the home. Third you can only have 16 Moca devices on a network. By devices I mean Moca adapters. Just use a switch we’re you have more than one machine. 

 

The only thing about moca Moca that makes it not as good as Ethernet is its half duplex. Meaning it can only clone direction at a time.
