Built-in ADSL Modem - Choose Yes if you have an ADSL broadband connection and will also need a modem. Choose No if you have a broadband connection other than ADSL or if you already have an ADSL modem that you wish to plug into a separate Router.

ADSL2/2+ - ADSL2/2+ are the newest and fastest ADSL standards offered by many ISPs. Almost all ADSL modems are ADSL2/2+ compatible anyway these days and these are almost always backwards compatible with older ADSL1 standards too so this option may be a little redundant but tick it anyway to be on the safe side.

WAN Ports - WAN stands for "Wide Area Network" which is the Internet. Normally a modem would be plugged into a WAN port. Some routers feature 2 or more WAN ports to allow for load sharing or failover between 2 or more ISPs.

3G Support - Some routers can support certain types of 3G modems. See my 3G FAQ for more.

LAN Ports - These are the ports you plug your PCs and other devices into (LAN stands for "Local Area Network"). 10/100 means it can allow data transfers of up to 100 mpbs. 10/100/1000 is also know as Gigabit and will allow data transfers of up to 1000 mbps when used in confunction with gigabit adapters in your PCs and other devices. Be aware that very few routers have more than 4 ports so selecting "more than 4" will restrict your choices so I recommend leaving this option at "whatever" or "Four", or select "One or more" beside gigabit if you'd like gigabit ports. If you find the perfect router with everything you need but you need more ports, it's a simple matter to plug it into another switch to have has many ports as you like.

SPI Firewall - SPI stands for "Stateful Packet Inspection" and is a smart Firewall that can examine each packet of data, inbound and outbound, and automatically detect and block common forms of attack by hackers. See Router FAQ 2.7 for more.

Content Filtering - Content Filtering means blocking access to certain material available on the web and is usually achieved by using either a keyword list, URLs or both. See Router FAQ 2.8 for more.

Wireless: For more information about wireless standards and the differences between 802.11g & N etc see Wireless FAQ 1.13.

Detachable antenna/s - A detachable antenna can be an advantage if you ever find the need to upgrade to a more powerful antenna. See Wireless FAQ 1.4 for more about increasing wireless range.

VPN Passthrough - VPN is Virtual Private Networking. This is a way for Computers in different locations to Network to each other using the Internet instead of a direct cable. See Router FAQ 2.10 for more.

Built-in IPSec - IPSec is a type of VPN. See Router FAQ 2.10 for more.

Built-in PPtP Server - PPtP is a type of VPN. While it's the easiest to use, the number of simultaneous PPtP tunnels is usually far more restricted than multiple IPSec tunnels. See See Router FAQ 2.10 for more.

Built-in PPtP Client - PPtP is a type of VPN. While it's the easiest to use, the number of simultaneous PPtP tunnels is usually far more restricted than multiple IPSec tunnels. See See Router FAQ 2.10 for more.

QoS - Quality of Service. An ability to give priority to particular types of Internet Traffic. eg VoIP where you don't want the bandwidth being chewed up by another application which might adversely affect the phone call quality.

FXO Ports for VoIP - Foreign Exchange Office. Looking at the phone cable that runs between a phone socket and a phone, the FXO port is the one that the cable plugs into on the phone itself. Routers that feature FXO ports allow your existing copper line to access the same telephone handset so if the Internet is down or the power is out it will "fail over" to the old copper line. Many of these products will also allow an incoming call to either your copper phone number or your new VoIP phone number to make the same telephone handset ring.

FXS Ports for VoIP - Foreign Exchange Subscriber. On a Router, the FXS port is the port that you'll be plugging your telephone handset into. If a Router has more than one FXS port, each additional port allows for an extra VoIP phone number.

USB Print Server - A Print Server allows a USB Printer to be plugged into the Router itself rather than a PC so it can be accessed by other network users without relying on any particular PC being switched on. Be careful though. Multifunction printers usually aren't compatible and there may be others that just won't play ball too. See the USB Print Server page for compatibility lists.

Parallel Port Print Server - A Print Server allows a parallel port Printer to be plugged into the Router itself rather than a PC so it can be accessed by other network users without relying on any particular PC being switched on.

USB Storage - Some routers have a USB Port that can accept a USB Hard Drive or Flash Drive to use as cheap Network Attached Storage

UPnP - Universal Plug and Play. A smart network protocol that allows ports to be opened and closed on request. See Router FAQ 2.9 for more.

Dial-up/ISDN Support - Routers with Dial-up & ISDN support allow failover to these types of Internet connections if the main broadband connection is down but they usually can also be used solely for these types of Internet connections if you don't have access to broadband.

DDNS Client - DDNS stands for Dynamic Domain Name Server. Most Routers include a built-in DDNS client. See the Remote Access page for more about DDNS.

Warranty Period - Warranty periods can vary anything form 12 months up. Some manufacturers also offer advanced replacement but this is usually only in their corporate offerings and/or for an additional fee. It may be worth reading the fine print if you will require zero downtime in the event of a failure.

Price range - Choosing a price range will omit products not sold at the OzCableguy online shop.

Include Obsolete - "No" is selected on obsolete products by default but if you would like to see them in your search results choose "Yes".
