Re: ADSL modem, firewalls

What did you have her ping an IP Address or a domain name?

Was she attempting to ping the gateway address on the lan side of this adsl device? In that case either DHCP is not supplying a dynamic IP address or the static IP address, subnet mask, default gateway address configuration in her adapter is incorrect.

If she pinged an IP Address and it is not the prior issue I would favor that the modem side of the device are not set properly for her internet service provider. The ISP's support/help website may help in determining the correct values here.

If she pinged a domain name like then it could be the same as either of the above or it could be a lack of DNS addresses in the router or her local adapter configuration whereever they are preferred in her environment?

What cable do i need?

You should give more detailed information!
If I understand correctly, you have an ADSL over a normal landline with a splitter between the phone and the modem. If you now want to move the modem you need a simple telephone-cable with at least two wires.

Installation of the modem Comtrend CT-361 under Windows Vista

This appears to be an old model. Their website isn't very user friendly and they list no kind of tech support available. You can contact them here.

They might be able to help you out if you call them but there is nothing available on their website or anywhere else that I see on the web. The product appears to be older then Vista and might have never had a Vista driver made for the product.

I have a Zoom X6 ADSL modem that keeps dropping my internet signal. How can I correct this?

is it wireless connection or ethernet? Zoom routers have a firewall and when you have something connected that the firewall doesnt like (Xbox 360 or Gaming) it will drop the connection. goto and it will give you instruction on how to by-pass the firewall using an different IP address.

Zoom router

Have you tried configuring the ADSL modem router for the internet connection?
Its possible that since you have changed the ADSL modem router, you may have to configure the ADSL modem router for it to work fine. The configuration depends on what Internet provider you have but you may try these steps for now:

1. Make sure the connections are correct. Connect the computer to the LAN port and the ADSL line to the port assigned for that behind the device.
2. Launch an Internet browser and access and press enter. If a dialog box appears, set the user name as admin and password as zoomadsl and press enter.
3. On the basic setup page of the ADSL router, set the appropriate encapsulation and other settings based on the settings of your provider. If you do not know the settings for your provider, there is a table specified on the user guide for the ADSL router. Here is the link:
