Router Tips to Make Your Wireless Faster

Here are some tips and tricks to get a little extra oomph out of the least sexy piece of tech you own.

The router is the technological workhorse of the modern home, bringing Internet to your many devices. A router’s wireless speed is usually a user’s main concern: Unlike wired networks, wireless networks seem to suffer interference from objects in our everyday lives--should the router be above the dryer, or below; next to the microwave, or above? Wireless speeds can also be affected by too many devices sharing the same access point as well. Your device is fighting for limited bandwidth. Many basic ways to improve your Wi-Fi network are available, such as placing the router in the center of the area you want it to cover, keeping the router away from metal objects that could block the signal, or making sure there aren’t too many other radio-enabled devices broadcasting on a 2.4GHz signal (standard for most older routers). But other ways to improve your signal may be a little less apparent. Here are some of those tricks (feel free to add your own workarounds in the comments below).

Check Your Speed

Although most people can gauge if their home wireless is too slow or not, checking the speed of the connection will let you know for sure whether you’re within range of the speed promised by your provider. Downloading a lightweight piece of software like LAN Speed Test gives you upload and download speed numbers in megabits per second (mbps), which you can check against your ISP’s promised speed to see if your network is actually slow or if you just need to pay for faster service. You’ll probably need to run the test multiple times and at different times of the day to get a real sense of how fast your Wi-Fi is overall, as crowding on the 2.4GHz spectrum could cause slowdown during the busiest times of the day for Internet traffic. Change the ChannelIf your wireless is weaker than it should be, you can try manually adjusting the broadcast channel to find one with fewer wireless routers competing for space. If your router is relatively new and automatically chooses which channel to broadcast from, then you won’t get too much use out of pinning your wireless down to a single channel, but for older routers it’s worth looking into. First you’ll want to go into the router’s graphical user interface (GUI), by typing the router/gateway address into the address bar in a browser window while your computer is connected to the router’s wired or wireless network. You can usually find the router’s address on the router itself, in the instruction manual, or online if all else fails. For example, if you have a D-Link router, you’ll type http://192.168.0.1; if you have a Linksys, you’d type http://192.168.1.1. The browser will prompt you to enter your user name and password. The exact navigation through the GUI for each router is different, but once you find the router’s wireless options (usually under headings like “LAN” or “Network”), you should see a “wireless channel” option. In North America, you can broadcast from channels 1, 6, and 11. Try switching to one of those three channels that’s not currently in use and see if it speeds things up. Add Some Hardware

Changing the actual hardware that makes the wireless signal waft through your house is an easy way to strengthen a wireless signal throughout a larger area. While most routers come with omnidirectional antennae (meaning they broadcast signal in all directions), you can also invest in a single-directional antenna that should double the strength of your signal, but only in one direction. This is great if you must place your router by a wall, and you don’t want to waste resources transmitting half of the wireless signal through the wall or window. Single-directional antennae can cost anywhere from $20 to $120.Wireless repeaters do a similar thing, basically just repeating the signal put out by your router and helping you cover more space with Wi-Fi. These also cost around $20 for a low-end repeater, but if you’re up for a little DIY you can make your own wireless repeater for free by uploading custom firmware from DD-WRT to an old router (step-by-step instructions here, and an explanation of DD-WRT below).Another hardware-related change: if you have multiple rooms you need to cover with your signal, consider buying a hybrid Homeplug/ wireless router device. Homeplug technology uses the AV line in your house to transmit broadband signals to other rooms, and if you include a wireless router on the adapter, you’ll have a Wi-Fi signal right there in the room with you.

Check Who’s on Your Network

You never want to leave your wireless signal without at least some sort of protection, and it’s worth noting that there are different levels of security on every router. Again, you’ll want to go to your router’s GUI and check its wireless security settings. Often, there will be a drop-down or click-to-select menu to allow different levels of security. WEP is the weakest form, and is easily broken; WPA is much more secure; and while WPA2 is the most secure, it can sometimes be incompatible with older devices on your network, so WPA is probably the best bet if you’re not sure what you want. Again, somewhere in your router’s configuration (under “wireless” or “status”) there should be a list of devices that connect to your system. Keep in mind that this list of devices will also include the laptops and smartphones of any guests who used your Wi-Fi recently, or any cameras, printers, or other Wi-Fi enabled devices that you might use around the house. If you’re unsure, you can match the Media Access Control (MAC) addresses listed on the router GUI with the MAC addresses of your various devices. If you do find intruders, you could change your wireless password, or some routers will allow you limit the number of devices that can connect to your network. Of course, there are programs out there that will allow you to triangulate the location of the moochers based on network signals. While the legality (and sanity) of trying to track down people who are using your Internet is questionable (and not sanctioned by PCWorld) there would probably be nothing wrong with knocking on your downstairs neighbor’s door and politely asking them in person to get off your Wi-Fi. There is, of course, the famous “Upside-Down-ternet” gag, where you turn the Wi-Fi thief's browser pages upside down, or make their browser pages blurry, or replace them with kittens! While it sounds fun, it’s a pretty advanced trick, so the average user might want to switch to WPA security and password-protect the network instead. Adult Site Blocking With Open DNS

Many new routers come with parental control options built into the device’s features. If you have an old router, however, you can use a service like OpenDNS. When your browser receives the command to retrieve a URL, it must go through a DNS server, which will look up the site’s numeric IP address. OpenDNS uses it’s own DNS lookup technology to resolve your browser’s page, meaning it can often bring up a web page faster. But one of the big perks for parents is that it also can block phishing attacks and adult sites that might get your kids in trouble. OpenDNS doesn’t even require that you subscribe with them (the free version is ad-supported). Simply go to your router’s GUI and switch from an auto-generated IP address to a static IP address; then in the fields for DNS (there are usually 2 to 4 spaces for you to add a DNS lookup number), enter OpenDNS’s look-up numbers, which you can find on the OpenDNS site. Doing this from the router, rather than just configuring OpenDNS on a specific computer, will protect all the computers connected to that router. Install Updated or Custom Firmware

If you have an older router, or the settings on your new router don’t offer all the functionality you’d like, try upgrading your router’s firmware. Often, your router manufacturer will have firmware updates that you can easily download from the manufacturer’s website. And if you really want to supercharge your router, you can even upload custom firmware provided by DD-WRT. While a lot of newer routers offer out-of-the-box DD-WRT compatibility, you can check on the DD-WRT website to see if your older router is compatible with the custom firmware. Upgrading can mean better firewalls, the ability to designate how much bandwidth each device on your network gets, and even client isolation, so that wireless users can connect to the network without being able to see each other (an important part of hosting a public access point). Follow the directions on the site to flash your router with DD-WRT, and then use it to modify your router to fit your needs. Hybrid Modems/Routers Aren’t Off Limits

If your Internet service provider requires that you install a hybrid modem/router, you can try adding another router onto the system to get different functionality. When I moved into a new apartment recently, I decided to subscribe to AT&T Uverse, which uses fiberoptic cable to bring the Net to your computer. AT&T requires subscribers to use a hybrid router/modem, and in my case the company installed a 2Wire 3800HGV-B modem/router. The Wi-Fi was okay, but the device had an 802.11g wireless access point, and I wanted to try my newer TRENDnet TEW-691GR router, which had an 802.11n access point. In order to broadcast wireless from the TRENDnet router, I modified the two routers to work with each other. First, I went to the 2Wire’s summary status page, and under “Internet Details” recorded the primary and secondary DNS numbers, and also the range of the IP addresses listed under “Private Network DHCP info”, which in this case happened to 192.168.1.64 - 192.168.1.254. Then I connected an ethernet cable to a LAN port on both the 2Wire modem/router and the TRENDnet router, connected the TRENDnet router to my computer with another ethernet cable, and entered the TRENDnet configuration page. I navigated to “network” and “WAN setting” (although with other routers you might just look for the option to change the connection type and the DNS server setting). I changed the connection type to “Static.” In the field for IP address, I entered a number within the range given above; in the “subnet mask” field, I entered 255.255.255.0; and in the “default gateway” field, I entered the original 2Wire router/modem’s gateway address, as found on the router itself. Then, under DNS Server Setting, I entered the primary and secondary server settings that I found in the 2Wire’s configuration page. I saved everything, then went back to the 2Wire device. In the 2Wire’s configuration page, I first went to “system info,” then “Event Notifications,” and checked “enable detection of router-behind-router conditions.” Then, I navigated to the “Broadband” tab and clicked “link configuration.” Under “add additional network,” I checked “enable” and gave the TRENDnet router’s address (which I had used earlier to enter the TRENDnet’s GUI ) and the subnet mask 255.255.255.0. Don’t forget to keep saving your settings. With the TRENDnet router still connected by a LAN port to the 2wire’s LAN port, both devices should be on and giving a wireless signal. When you can connect to both wireless networks successfully (you may have to close out of your browsers or do a “power cycle” by turning both the routers on and off), then you can go into the 2Wire’s modem/router menu and disable the “wireless” tab.At this point, no wireless signal is coming from the 2wire, and all of the wireless transmitted in my apartment is at 802.11n standards. This workaround seemed to make my wireless slightly faster, but more unreliable. The network connection would suddenly crash, but when it was up and stable I seemed to be able to download videos faster. I would recommend activities of this type for experimentation only, as I ultimately just went back to the more stable 2Wire wireless network.
