The modem needed to be set to a 192.168.x.x network, and the SG300 Firewall WAN port needed to be set to a dummy IP on the same network for it's IP, and the specific 192.168.x.x address for the gateway and DNS.

I have an at&t 2wire 2701hg-b but i dont have at&t internet i have charter and i am not able to figure out how to get my internet to work with this router please help


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.

Keeps losing connection? charter says no problem with them, motorola is no help.....


Check / replace the power supply. Also check your cable. If you have access to where the cable comes into your house, try connecting a brand new cable at the box and connecting to the modem. If that solves it, then you need to have the house cabling checked / replaced. If not, then there is most likely a fault with the modem. Do you have any friends with cable Internet you could check out the modem at their house? Maybe swap cable modems with them for a short time to see if the fault travels with the modem. If both work at your friends house and neither work at your house it is is a problem with charter and they need to come out and verify the signal strength if they have not done so. If the problem is intermittent, is it a particular time of day? Cable services theft is a big problem and somebody may be tapping in to the line causing signal loss.

If none of the above helps, post much more information and what you have done to solve the problem.

Best of luck, Jim

How do i get my hp pavilion a320n to connect to the internet through charter


Usually Charter will supply the modem necessary to connect your computer- you will need an ethernet cable as well. Once you have the cable modem connected- connect the ethernet cable to your pc. At that point, you should be able to connect to the internet

I have charter internet with a modem and i have a westell 327w wireless router/modem. How can i connect the two modems to work wirelessly?


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.

Cable modem connection keeps repeating checking and then down over and over, tried a different router works fine, tried a different modem same issue


I had a similar problem a while back when I bought a new cable modem. I didn't realise that my cable provider needed to have the serial number of my cable modem configured on their system.

I ended up calling them to ask them about the problem.

There is no way I could have solved it without calling them.

I think it is to do with stopping unauthorised users from connecting to the cable.

I remember they wanted my name, age and grandma's inside leg measurement before they would help me.

So if you have nothing to hide just give them a ring and make them help you. This is what you pay them for after all.

Can't connect to AT&T VPN


as you told me that all the ports are open so in that case you can get in touch with your ISP and ask them to enable IPPASSTHROUGH on your office laptop.

Cable modem


Go and buy a router. Plug your existing modem into the WAN port and your computers into the LAN port. You could even get a wireless router and connect your upstairs computer wireless. Be sure to lock down your SSID (Wireless Access Point Broadcast Name) so your neighbors or people driving by don't get on and do bad things on your network.
