**CenturyLink recommends the default modem setup.
CenturyLink strongly recommends protecting your wireless network with a form of wireless encryption.
WPA (Wi-Fi Protected Access) is the preferred form of wireless security. If your wireless equipment
is not WPA compatible, CenturyLink recommends the use of WEP (Wired Equivalent Privacy) security.

- Q: Can I connect multiple wired (Ethernet) connections to my modem?
- A: Yes, this modem has 4 ethernet ports on the back.
- Q: Does my modem act as a firewall?
- A: This modem provides security using a Firewall and Network Address Translations (NAT), which acts as a barrier between your network and the Internet. Learn more about the on-board firewall here.
- Q: Which Virtual Private Networking (VPN) protocols are supported?
- A: This modem supports pass-through for IPSec, PPTP and L2TP.
- Q: When would I use WEP wireless security?
- A: You would use WEP for wireless security when you have an older wireless adapter that is not WPA capable. If your wireless adapter is not WPA capable, check the manufacturer's website for updated firmware. Despite the flaws in WEP, it does provide some security, particularly when compared to no security at all.
- Q: What can interfere with my modems wireless signal?
- A: The physical environment can have varying effects on signal strength and the quality of your wireless modem. The more dense the object the greater the interference(e.g., a concrete wall causes more interference than a plaster wall). Concrete or metal reinforced structures cause a higher degree of signal loss than wood, plaster, or glass construction. Devices that give off EMI (Electro-Magnetic Interference) can also adversely affect your signal strength. This includes things like garage door openers, microwaves, cordless phones, and wireless baby monitors.
- Q: What is Modem Firmware?
- A: Firmware is like an operating system that tells your modem how to operate. It provides the modem's hardware with operating rules, instructions, and logic.
- Q: Why Should I Upgrade Firmware?
- A: Firmware upgrades can add new features, improve performance and enhance the security of the modem's current firmware.
