Ten mistakes to avoid when buying Wi-Fi

Update Setting up a wireless home network is a new concept for most of us and it can be a daunting prospect for the tech-savvy, let alone novices.
Before you hand over your money on new gear, check out our list of tips that will help you avoid buyer's remorse.
1. Check out warranty and support options
All networking gear should come with comprehensive documentation, easy-to-follow setup instructions, at least one year of warranty coverage, and -- because networking can be complicated -- free phone support (extra points if it's available 24/7).
2. Don't mix and match wireless standards
Networking devices have to speak the same language and use a common physical medium to work best together. So if your gift recipient's network is 802.11g, stay away from buying 802.11a-only devices.
3. Avoid products with different security features
Most new wireless products will support both WEP and WPA encryption, which we strongly recommend. To talk to one another on a secure network, all devices must use the same encryption scheme, so double-check before you buy.
4. Don't let security ruin the fun
Ironclad security is great, but a firewall can also keep your friends from playing games or setting up servers. Make sure the router you buy includes a DMZ and a port-forwarding feature so that its users can make the most out of the Internet.
5. Don't mix and match gear from different vendors
You'll often find bells and whistles on networking products that increase throughput or give you access to special features. Such extras aren't typically standards-based and often work only if all of the devices carry the same brand name.
6. Leave some room to grow
Networks have a way of growing, so it's always good to have a variety of expansion options. Multiple Ethernet ports and WDS, or wireless distribution system, support will help you future-proof a network.
7. Steer clear of a network that gets in the way
Ethernet equipment is fast, but it also requires the recipient to run cables through the house. Wireless gear solves this problem, but it might interfere with other wireless devices in the home or the office. Make sure that the gear you buy is right for the space.
8. Don't be afraid to be sexy
Pick a router with a design and a colour scheme that will blend into your -- of your giftee's -- crib. If networking gear simply doesn't figure into the interior design scheme, choose a router with a built-in bracket that will make it easy to mount on a wall or hide behind a bookshelf or a sofa.
9. Don't blow your cover
Buy a router that lets you turn off its beacon. Beacons periodically advertise a router's presence so that client devices know that they're there. Get a router that lets you disable the beacon so that you can fly under the radar and go undetected by snoops.
10. Be a nice neighbour
Buy your broadband service from a provider that doesn't mind if you share your connection.
