AT&T
Frequently Asked Questions (FAQ)
Here is a list commonly asked
questions about AT&T DSL and other services.
What is a firewall? Do I need one?
A firewall provides a virtual wall between your computer and
the Internet, protecting your computer or network from attack.
Attempts to break into computer networks often occur through
Internet connections. Firewalls can be either hardware or software.
To help protect your personal information from potential hackers,
AT&T Yahoo! offers a free, downloadable ZoneAlarm personal
firewall to all Members.
To download the firewall software:
- You must have one of the following operating systems: Microsoft
Windows 2000/XP
- Visit http://www.zonelabs.com/sbc
- Select the firewall version that suits you. Your AT&T
Yahoo! membership includes the basic ZoneAlarm firewall software
at no extra charge. Or you can choose the enhanced version,
ZoneAlarm Pro, for an additional charge.
Can I connect two computers to the same high-speed Internet
line with separate modems?
No. Placing two high-speed modems on the same high-speed Internet
line and trying to connect both to the Internet at the same time
will cause both high-speed modems to fail.
You can, however, share an Internet connection. Two technologies
have evolved to allow your computers to share Internet access.
You can create a small network (using standard networking products)
without opening your computer up to sharing files, printers or
privacy issues.
The easiest solution to implement would be a hardware-based router
technology, such as the AT&T
Wireless Gateway (2Wire HomePortal) device. You can turn
off either computer and not affect the Internet access of the
other computer.
The other technology for Internet sharing is a software-based solution,
turning the primary computer which is connected to the high-speed
Internet line into a gateway device. The software enables you
to share multiple connections to a single Internet access point.
That requires you to connect the computers which you want to
share the Internet connection. Since this solution requires active
software running on the primary computer, you must keep that
computer powered up and connected to the high-speed Internet
service at all times. A firewall application may or may not be
available with this software. AT&T does not sell or recommend
this software.
Either of these solutions will work with your AT&T Yahoo!
High Speed Internet service. We have more information available
about our home and office
networking products, as well as pricing
and product configuration details in our online store.
Do you offer fee-based technical support services?
Technical support of high-speed Internet access service
is available at no charge. Occasionally, there will be hardware
or software which was not initially installed with our high-speed
Internet service at the time of purchase. For these items,
we offer optional services, such as an on-site service installation
or our Support+ service. Please note, additional service
charges may apply.
Can I get a static (sticky) IP address?
Yes. With our S Package products, you are assigned static
(sticky) IP addresses. These services are available for both
business and residential customers.
AT&T Yahoo! High Speed Internet does not offer a package
with a single static IP address.
Can I have more than one IP address with AT&T Yahoo!
High Speed Internet?
Yes. We provide 5 static IP addresses with an S Package
product. These packages are available for both residential
and business customers.
What is an IP address?
IP stands for Internet Protocol. An IP address enables
a computer to be identified on the Internet while the
user is online. Every device connected to the Internet
has a unique IP address.

What do I do if I get a computer virus?
If you know or suspect that your computer has been

and services available for online protection.
The simplest way to protect yourself from email viruses
is to not open emails with attachments that look suspicious.
