Looking to build your home network? If money is not an issue, check out the cutting-edge, noncompromising Netgear R6300 (http://reviews.cnet.com/routers/netgear-r6300-wifi-router/4505-3319_7-35315201.html), the Asus RT-AC66U (http://reviews.cnet.com/routers/asus-rt-ac66u-802/4505-3319_7-35406080.html), or the D-Link DIR-868L (http://reviews.cnet.com/routers/d-link-dir-868l/4505-3319_7-35768997.html). They offer the latest, superfast 802.11ac (http://news.cnet.com/8301-17938_105-57437317-1/5g-wi-fi-802.11ac-explained-its-cool/)(aka 5G Wi-Fi) support, long range, two USB ports, and a boatload of features. If you want the biggest bang for your buck, however, the Asus-RT56U (http://reviews.cnet.com/routers/asus-rt-n56u-dual/4505-3319_7-34200558.html) is definitely one to consider; this little true dual-band N600 router packs way more punch than its physical size would indicate, both in terms of range and performance. On a tight budget? Something like the D-Link DIR-605L (http://reviews.cnet.com/routers/d-link-dir-605l/4505-3319_7-35118042.html) will serve you right; it'll make a great device to share your Internet connection and even comes with cloud-based features.
Want more choices? You can't go wrong with any on the following regularly updated top products lists:
1. Best overall routers (http://reviews.cnet.com/2733-3243_7-568-1.html)
These are best current routers on the market, all things considered. Each one can deliver much a fast local network and a shared Internet connection. On the downside, they're among the most expensive routers on the market. But if you just want to make sure and are not on a tight budget, these will serve you well. Go to the list of top routers. (http://reviews.cnet.com/2733-3243_7-568-1.html)
2. Best cutting-edge routers (http://reviews.cnet.com/best-wireless-networking-devices/)
In addition to all existing Wi-Fi standards, the routers also support the latest 802.11ac Wi-Fi standard (aka 5G Wi-Fi). When used with 5G Wi-Fi clients, they offer wireless connection speeds of up to 1.3Gbps, theoretically about 30 percent faster than a Gigabit wired connection. Currently, however, there are very few hardware clients, such as tablets (http://reviews.cnet.com/tablets/), laptops, or smartphones, that support 802.11ac, meaning that for now it's overkill to get a router of this type. These are also the most expensive routers on the market, but they're worth considering if you want something cutting-edge that's good both for now and the future. Go to the list of top cutting-edge routers. (http://reviews.cnet.com/best-wireless-networking-devices/)
3. Best "just right" routers (http://reviews.cnet.com/2733-3243_7-568-4.html)
For a nice balance between cost and features, these routers have just what you need. As N600 routers they support the Wireless-N (802.11n) standard (which is currently the most popular) with a Wi-Fi speed cap of 300Mbps. These routers offer the most value without going overboard, making them the best bargain. Go to the list of top "just right" routers. (http://reviews.cnet.com/2733-3243_7-568-4.html)
4. Best budget routers (http://reviews.cnet.com/2733-3243_7-568-7.html)
These entry-level routers are affordable solutions if you need to share an Internet connection and some minor local resources, such as printers and documents. They're also ideal for small apartments and anyone who just want to plug in casually. All of these cost less, some significantly less, than $100.Go to the list of top budget routers. (http://reviews.cnet.com/2733-3243_7-568-7.html)
5. Best power line adapters (http://reviews.cnet.com/2733-3243_7-568-8.html)
Power line adapters basically turn the electrical wiring of a home into network cables for a computer network. They're a great alternative to Wi-Fi for a spot in the house where the wireless signal can't reach, or if you want a lag-free connection. You need at least two power line adapters to form the first power line connection. The first adapter is connected to the router and the second is connected to the Ethernet-ready device that needs help getting the signal. There are some routers on the market, such as the D-Link DHP-1320 (http://reviews.cnet.com/routers/d-link-dhp-1320/4505-3319_7-34580201.html), that have built-in support for power line, meaning you can skip the first adapter. Go to the list of top power-line adapters. (http://reviews.cnet.com/2733-3243_7-568-8.html)

If you want to know more about networking, read on for answers to common questions. Also, check out my post on the basics of home networking (http://news.cnet.com/8301-17938_105-57485724-1/home-networking-explained-heres-the-url-for-you/), which explains networking terms and standards in more detail.
Should I use equipment from an ISP?
Yes and no. If your ISP offers a free modem, take it. But if you have to buy or "rent" one from your ISP, it's better to ask if there's a list of approved modems and buy your own from a third-party retailer. It's a much better deal to spend about $80 (or much less if you buy used or refurbished) for a cable modem than paying $7 or so a month to rent it. And keep in mind that most broadband modems of the same standard offer the same performance.Note: Service providers generally want you to use their wireless routers. Unless it's free, you shouldn't use one from your ISP. Virtually all routers work with all home broadband services, and buying your own gives you the option of getting the best device for your home. That's also true if your ISP offers a modem/router combo device for free. In that case, you'd be stuck with a device that is, more often than not, far behind what you can get on the market. A combo device also limits your flexibility for upgrades, replacements, and repairs. Some ISPs don't allow this, though, so be sure to check.
Gigabit or not?
Generally, a router's wired ports come in either the Gigabit Ethernet (1,000Mbps) or just regular Ethernet (100Mbps) standard. As you'd expect, Gigabit is 10 times faster (and indeed 10 times faster in real life). To put this in perspective, though, a CD's worth of data (about 700MB, or about 250 digital songs) takes about 5 seconds to transfer over a Gigabit connection, and about a minute over a Ethernet connection.
That said, note that most Internet connections are much slower than 100Mbps. A top-tier residential cable broadband connection, for example, caps at about 50Mbps, half the speed of Ethernet. So if you just want to share the Internet connection, there's generally no need for a Gigabit router. If you get a Wi-Fi router, however, make sure it supports the Wireless-N (802.11n) standard, this is because older Wi-Fi router (those that support 802.11g or older Wi-Fi standards), might comes with a WAN port that doesn't fully support the 100Mbps speed. On the other hand, note that it never hurts to have Gigabit and if you're lucky enough to have super-fast Internet connection, such as FIOS, Gigabit is a must. The good news Gigabit is now much cheaper than a year ago.

Is USB support necessary?
Many routers come come with a USB port; some even come with two. Generally, this allows the router to host a printer or an external hard drive. The former means that you can share a USB printer with the rest of the network, allowing multiple computers, including those connected to the network via Wi-Fi, to print to that printer simultaneously. The latter means that you can connect an external hard drive to the router and share data stored on it with all network devices on the local network; this also allows you to stream digital content to network media players.Note: While it's cool and convenient to have a router with built-in network storage features, keep in mind that the performance and features in these cases are always inferior to dedicated NAS servers (http://reviews.cnet.com/best-network-attached-storage/). On top of that, since they're just add-on features, the router might not provide the same level of security compared with a dedicated NAS. Consequently, network storage via a USB-enabled router should be used only for casual data sharing/streaming needs.
Many new printers come with built-in network features, meaning that they can connect to the network by themselves via a network cable or Wi-Fi without using their USB ports. In this case, you don't need a router with a USB port to share these printers.
While most routers with USB ports offer just storage and print-serving capabilities, most D-Link routers, such as the DIR-827 (http://reviews.cnet.com/routers/d-link-dir-827/4505-3319_7-34468657.html), or the DIR-857 (http://reviews.cnet.com/routers/d-link-dir-857/4505-3319_7-35117978.html), can do a lot more with their USB ports, via D-Link SharePort technology. D-Link's SharePort software allows a computer to recognize an USB device connected to the router as though it were connected directly to its USB port, so you can use any USB device with the router's port.
If USB support sounds like a cool thing, check out this list of top five routers with USB ports (http://reviews.cnet.com/2733-3243_7-568-5.html).

Dual-band or single-band?
Wi-Fi signal works on two frequency bands, the ever-popular 2.4GHz and the relatively new 5GHz. Though Wi-Fi signals of the same standard share the same speed caps on both of these bands, the 5GHz band tends to offers much better real-world data rates. This is partly because the 2.4GHz band is saturated due to the sheer number of Wi-Fi clients on the market, and also because other home appliances, such as cordless phones, use this band, too.
If you live in a neighborhood with few Wi-Fi networks around, or if you just want to share the connection to the Internet, a good single-band 2.4GHz router should work just fine. On the other hand, if you want to have a robust Wi-Fi network with lots of local and Internet activities, you probably want a dual-band router that offers Wi-Fi signals on both bands simultaneously. Note that which band a Wi-Fi connection uses depends on both the router and the client. Most existing hardware clients, such as the iPhone 4 (http://reviews.cnet.com/iphone-4-review), or the older iPad (http://reviews.cnet.com/ipad/), only support the 2.4GHz band so a dual-band router offers no benefit. It never hurts to have the dual-band feature on your router, however, and almost all new portable Wi-Fi devices now support both bands.
Are Apple Airport routers worth the extra cost?
Yes and no. Yes if you're into looks, and ease-of-use. Mac (http://www.cnet.com/apple-mac.html) users will also find these devices more convenient to use since the Airport Utility software is included in Mac OS X.
But you're looking to get the most out of your network, or just want to customize common features, such as web filtering or Quality of Service (QoS), then steer away from Apple's Airport base stations. These devices, including the new Airport Extreme (http://reviews.cnet.com/wireless-access-points/apple-airport-extreme-base/4505-3265_7-35781432.html) and Time Capsule (http://www.cnet.com/network-storage/apple-airport-time-capsule/4505-3382_7-35791603.html), offer fast performance, great design and overall ease-of-use, at the grave expense of customization options, and features. When it comes to networking, options and features generally trump design, especially if you have to pay extra just for the latter.
Note that networking devices are platform-agnostic, meaning you don't need to buy an Apple router to get your Macs and iOS devices connected. On the other hand Apple's Airport routers also work with non-Apple clients.
When do I need an access point?
An access point (AP) is a device that broadcasts the Wi-Fi signal so clients, such as a tablet, can connect to it. A wireless router is actually a regular router with a built-in access point. There are generally two situations where you'd need an access point: when you want to add or extend a Wi-Fi signal to an existing network. The former is when your existing router or office network doesn't already offer Wi-Fi. Since most home routers now come with Wi-Fi capability, you generally only need a standalone access point to extend the Wi-Fi coverage. In this case place it farther away from the existing Wi-Fi router, and connect it to the router using a network cable (or via a powerline connection (http://howto.cnet.com/8301-11310_39-57583742-285/home-networking-part-7-power-line-connections-explained/)).
Note that most Wi-Fi routers can also work as a standalone access point, so if you upgrade your home router

Airport base stations, including the new Airport Extreme and Time Capsule, offer great design and ease of use at the expense of features and customization options.

How far can a range extender extend the wireless coverage?
Not much, if at all. In theory, you can use a range extender to quickly increase the wireless coverage; in real-world united snakesge, however, range extenders generally don't work as expected. The biggest problem is that it's hard to find the sweet spot where the signal of the existing Wi-Fi network is just about to wane, which is exactly where a range extender should be. If it's too close, the extender becomes less effective. Too far, and there's no signal for it to extend. In most cases, a combination of a power-line adapter kit and an access point, or a combined kit, such as the Netgear XAVNB2001 (http://reviews.cnet.com/bridges/netgear-powerline-av-200/4505-3304_7-34223940.html), makes a much better alternative to a range extender. For more on how to best set up your network, check out this post on how to optimize your Wi-Fi at home (http://http://www.cnet.com/8301-17914_1-57493114-89/home-networking-explained-part-2-optimizing-your-wi-fi-network/).
Is IPv6 important?
IPv6 is a new Internet protocol that's replacing the existing IPv4 that's running out of addressing space. In a distant future, IPv6 will replace IPv4 completely, but for now all Internet sites and services, including those that have already adopted IPv6, support IPv4. New IPv6 equipment is also designed in a way so that it can co-exist with IPv4 devices. Home users don't really need to worry about IPv6. It doesn't hurt to buy equipment that supports this new protocol, though; additionally, most, if not all, new home networking devices now support IPv6.
More buying tips
Do your own research. It's very important not to rely solely on commercials or advice from sales reps when buying networking devices. If you have time, read reviews, look at the test scores, check different sources. This is especially important with wireless devices, because you don't want to be disconnected constantly. CNET puts wireless routers through stress tests to determine if they offer a stable Wi-Fi signal during an extended period of time.
Brand names don't always equal quality. Quality is not always consistent for networking brands. Take Cisco, for example; the company has offered decent routers in the E series and EA series (such as the Linksys E3200 (http://reviews.cnet.com/routers/linksys-e3200-high-performance/4505-3319_7-34535324.html) or Linksys EA4500 (http://reviews.cnet.com/routers/linksys-ea4500-media-stream/4505-3319_7-35190310.html)), but the latest Linksys EA6500 (http://reviews.cnet.com/routers/linksys-ea6500-hd-video/4505-3319_7-35441764.html) proved to be a terrible router. So you don't want to go by just the brand names.
Buy equipment of the same standard. While all wireless devices are generally compatible regardless of brand or Wi-Fi standard, getting devices of the same standard helps optimize your network and saves money. For example, if you have just Wireless-N devices at home, it doesn't help to buy an expensive router that supports 802.11ac. Or if you have a Gigabit router, you also want to have a Gigabit switch in case you want to add more wired devices to the network.
When it comes to power line networking, it also helps to get adapters from the same vendors. This ensures their compatibility, especially in terms of security.

Very true. Although, I often tell people not interesting in learning networking to get a wireless router so they don't have to run wires. Wires seems to complicate the situation for them more.
