But, before you do so, I recommend that you change your router's admin User Name
and Password. Otherwise, anyone on your network that also knows the
manufacturer and brand of your router could look up the address and access your
router's settings and potentially lock you out of your own network. On this router, the
area to change the router User Name and Password is located under the System
Tools area, under Password. Remember, this is the Password to access your router's
internal settings and not your Wi-Fi password.
This User Name and Password allows you to change your router's settings, including
your network SSID, Wi-Fi password and security settings. While you may share your
Wi-Fi password with a visitor who wants to use wireless in your home, you should
never share your router User Name and Password with anyone, unless you wish to
give them administrative privileges on your network. An additional step you can take
to secure the administrative features of your router is to restrict administrative
access to select devices by MAC address.
The MAC, or Media Access Control Address, is the permanent identifier assigned to
all network enabled devices. MAC addresses are 12 digits, with every two digit
separated by a hyphen or a colon. There are a few ways to figure out your
computer's MAC address. But, in this case, our router displays this information in the
Security section of router options, under Local Management. If I check the box next
to the second option here, I can add the MAC address of the computer I'm currently
working from to this list.
Once the option is saved, only users using this specific computer can access the
router's settings using the admin User Name and Password.

Choosing the best WI-FI, WPA, and WPA2
Depending on your router you may have multiple frequency bands available. Back in
Chapter One, we discussed the different Wi-Fi standards, noting that wireless
G broadcasts on the 2.4 GHz spectrum, while wireless N can broadcast on either the
2.4 or 5 GHz spectra. In addition, some wireless N routers are dual band, equipped
to broadcast to both the 2.4 and 5 GHz spectra simultaneously, creating two
independent wireless networks for devices to connect to.
Within each of these, you also have the option to decide on the specific wireless
channel, as well as the channel width. We'll look at both Wi-Fi frequency and
channel options and examine what each means and how they effect the
performance of your network. In comparison to the 5 GHz frequency band, 2.4 GHz
band has greater range, but lower bandwidth, while being subject to more
interference from other networks and devices. I would recommend a speed test of
each of the two bands to see what kind of difference you're working with.
If you know all of your devices can connect to the 5 GHz band and speed is your
priority, it will be most beneficial for you to choose only the 5 GHz band. Of course,
the throughput provided by your ISP must also match the throughput of the 5 GHz
