Question 1

I have Xfinity Voice for the first time, but my router only has ethernet connections. Can I use this product to connect to my wireless phone?

Accepted Answer

Hi Faith.  No you can't use this product to do that.  There will be no "dial tone" coming out of the RJ11 side.  You'll need to either purchase or rent from Comcast a telephony modem/router.  Those will have the proper voice jacks already working.

Question 2

I bought a new modem to use with xfinity but it does not include phone jacks like the default gateway modem, will this allow me to use my landline?

Accepted Answer

This device is phone jack male to phone jack female (two ports).  If there is no phone jack female connection on your modem, then no.

Question 3

I have a rj12 cable ran instead of rj11.  will this work with the rj12 cable and be able to convert the cable to ethernet to use for ethernet to a tv?

Accepted Answer

This doesn't have to do with cable size.  I used the male side to plug into an ethernet RJ45 wall outlet and then the phone plugs into the female side of this adapter.  It allows you to use an ethernet RJ45 to plug in a phone which uses an RJ11 size.  You also must use a switch with your router in order to turn the ethernet into a voice line.  If that makes sense.

Question 4

I have a very old windows pc that only has the old phone jack for network connections, can I use this cable to convert my router RJ45 to interface?

Accepted Answer

No
