I currently have windstream dsl with 2wire modem/router. I am changing to Charter cable with their internet service. Question: Can I use my 2wire wireless modem with Charter cable internet service or do I have to get a cable modem from Charter?

This is a known issue with this model.. The power supply is not large enough to handle the extra current that is needed when the unit broadcasts on wifi.

att 2 wire is a Adsl Modem (Requires a telephone line jack to get the signals) but charter communication is a cable internet service (not DSL) , Requires a TV cable service for internet .
These two jacks differs and there working differs ..
Means : Att works with the username and password type of authentication but charter requires the MAC address of modem for authentication .
Therefore for a cable internet 2wire 2701hg-b modem cant be used . But yes in case charters has username and password authentication and works with the telephone jack in house then its possible to use the same modem.

I think the Westell Router/modem that you have must be the modem for the DSL connection.
Charter is a cable internet service provider.
You can not use 2 modems connected to each other.
You have a charter modem , you can purchase a wireless router only.
That will work.

that 2wire only works with DSL services, if you are using cable internet then no it wont work. If the surfboard digital voice is just a VOIP router then yes, plug the surfboard into one of the ethernet ports on the back of the 2wire.

ATT resolution: 2wire modem needed to be replaced.

Follow the dots -

2 wire DSL wire to back of DSL modem.

Ethernet cable out of DSL modem, to current router (if you have one).

Ethernet cable out of current router (if you have one) to new Wireless N router.

If you currently have a wireless G router, keep it, or, use the new Wireless G/N router alone. You will need to set up all security settings again if you remove your current router, and if the new router is N only, you will need to make sure all your wireless connecting computers have wireless N cards in them.

Whenever your dsl light on the 2wire modem turns red,it only means that there is a problem with the dsl connection to the modem. Here are some ways on how you can isolate the problem

1. check if your modem is properly connected to the phone jack by unplugging and replugging you phone cable
2. try to reboot the modem
3. if still getting the same lights, contact your ISP

The 2wire dsl modem/router cannot be use with a another cable modem , since this 2wire device is also a modem/router and its made for the DSL conenction that's why it wont work with Cox cable, the best thing that you can do is to ask Cox to give a wireless modem/router like this 2wire so you can still use the wireless connection of your computer..

Hope that helps..........

you cant use a cable modem and a dsl modem at the same time as its a dsl dialler and a router and a cable modem works differently, all the settings wont match, you will have to purchase a seperate router or cable modem/router
