Theoretically you can because the purpose your cable serves is a conduit for data transmissions. Just a few cautions here. Just as in any circuit, the more the wire is spliced,split, or anything that taps into it on its way . to the modem will add resistance to the line, thus it could degrade or "slow down" your signal. There is a splitter I know mediacom haves that will help with lessening this effect.

First you need to be more clear on what you are wanting to split, if you want to connect your tv to the Modem (for internet apps like netflix) or if you want to connect your tv to the coax cable line for basic cable tv channels. if it is for internet apps you need a router to "route" internet connections because your modem can only support 1 device at a time without a router. if you are you want to split the coax line you want to make sure you have enough signal to you modem. to check this 1. open you web browser 2. insert http://192.168.100.1/ into address bar and hit enter 3. click on "Diagnostic" if "Received Signal Strength:" is greater then -2 dBmV and your "Power Level:" is less than 50 dBmV you are safe to use a splitter and connect your tv. but please get a splitter and jumper from you local Mediacom office and don't buy them at radio shack or try to make them!

How do you connect a RCA router to a Sansung HD TV with Xfinity update


Mary, if you have internet, you will have a modem device. This device may be part of the router or it may be a separate unit. In any case, once this is determined and your internet is shared you will be able to connect your tv to your router. Your tv may be a wifi compatible set or not. Depending on which type of set you have, you will either connect a cable to the router or you will have to set up wireless. Wireless will be configured on your router. Once this is done, you can configure your tv to use the wireless connection. For more information, I will need exact make and models of your modem, router and tv. Also, google is a great source for documentation. If you decide to tackle this on your own, set up your modem, set up your router, then set up the tv. Hope this helps.

Cablevision wire goes to the modem. It should be the first device on the cablevision wire. If you need a splitter, it needs to be a GOOD one, connected DIRECTLY to the incoming Cablevision wire as it enters the house. Use good copper wire.

Order of events:
Connect the cablevision wire to the Modem.
Connect the Ethernet cable to the computer and the modem.
Power on the cable modem.
Right click the network Icon near the clock and click 'repair' (Or reboot the computer)
Apply for and get an account for cable Internet from your Cable company.
After a few days, cable Internet should work.

If you still have the modem, disconnect the coax-cable.
Connect the Ethernet cable.
Connect the AC power.

On your computer:
Click Start
Click Run
Type CMD and press ENTER
Enter IPCONFIG and press ENTER
Look for the "default gateway" IP-address, e.g., '192.168.2.1'
Start Internet Explorer.
Enter: http://192.168.2.1
to see if you can connect to the web-interface inside the router.
Good luck.
