Buyer's Guide - RoutersA router is the best way to share your cable or DSL connection with multiple devices. There are a few key features that you should be aware of when selecting a router.
Most routers come with several wired ports. This is often a great option to use if your computer has a wired ethernet port and is located near the router. If you wish to use several computers on wired connections, make sure the router you choose has enough ports for all of them. If you want to connect your computer with a wired connection but there isn't one on your computer, you can add a USB Ethernet adapter.
There are two main frequencies used by different wireless specifications - 2.4GHz, which is slower but has longer range and 5GHz, which can provide greater speed but at shorter distances. Here is a breakdown of what bands are used by each specification:
|Specification|| Used by
|| Frequencies Used
|| Max Speed*||Backwards Compatibility
|802.11b|| Older devices
|802.11a|| Older devices
| 802.11g|| Older devices||2.4GHz||54Mbps||802.11b|
|| Most current devices
|| 2.4GHz, 5GHz
||600Mbps||802.11g, often 802.11a
|| Newer devices
|| 2.4GHz, 5GHz
||1733Mbps||802.11b, 802.11g, 802.11n, 802.11a
*: These are theoretical max speeds and are rarely achieved in real-world settings. Max speed depends on building construction, number and kind of devices on the network and ultimately cannot exceed the speed of your cable or DSL connection.
Not all 802.11n routers are the same! There are different ratings of routers based on the theoretical max speed that the router's antennas can receive. For 802.11n routers, you might see N150, N300 and N600 on the box. Drop the N and that is the maximum rated Mbps that the router can handle in ideal conditions.
Number Of Users
The number of users and devices that might simultaneously connect to the router is of utmost importance in picking a router. Generally, the higher end the router, the more people it can support comfortably. Here are DoIT's recommendation for routers:
|Capacity|| # of users/devices
| 802.11ac (1733)
Some routers offer the option to add an external USB device to be shared on the connection, such as a USB printer or external hard drive. Apple's Time Capsule has a built-in hard drive that is used for backups.
As mentioned above, the construction of your building can greatly impact your wireless signal. A good way to estimate how much it will impact your network is to check your cell phone signal in different areas of your home or apartment.
If the wireless signal is weak in some spots of your home or apartment, it is possible to add a wireless range extender to increase the signal strength in the problem area. Another option is to use powerline networking to extend your network to areas where it is difficult for wireless to reach.
