If another station is sending a frame when the beacon is to be sent, then the access point or NIC in an ad hoc network must wait.

As a result, the actual time between beacons may be longer than the beacon interval. Clients, however, compensate for this inaccuracy by utilizing the timestamp found within the beacon packet information. A typical beacon frame is approximately fifty bytes long, with about half of that being a common frame header and cyclic redundancy checking CRC field.

As with other frames, the header includes source and destination MAC addresses as well as other information regarding the communications process.

This forces all other stations on the applicable channel to receive and process each beacon frame. The CRC field provides error detection capability. The beacon's frame body resides between the header and the CRC field and constitutes the other half of the beacon frame.

Each beacon frame carries the following information in the frame body:. Beacon interval. This represents the amount of time between beacon transmissions. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon and learn whether there are buffered frames at the access point.

After receiving a beacon frame, a station uses the timestamp value to update its local clock. This process enables synchronization among all stations that are associated with the same access point. Supported rates.

Each beacon carries information that describes the rates that the particular wireless LAN supports. For example, a beacon may indicate that only 1, 2, and 5. As a result, an With this information, stations can use performance metrics to decide which access point to associate with. Parameter Sets. The beacon includes information about the specific signaling methods such as frequency hopping spread spectrum, CTS Protection mode and RTS Threshold,direct sequence spread spectrum, etc.

For example, a beacon would include in the appropriate parameter set the channel number that an Likewise, a beacon belonging to frequency hopping network would indicate hopping pattern and dwell time. Capability Information. This signifies requirements of stations that wish to belong to the wireless LAN that the beacon represents.

For example, this information may indicate that all clients must use wired equivalent privacy WEP in order to participate on the network. An access point periodically sends the TIM within a beacon to identify which stations using power saving mode have data frames waiting for them in the access point's buffer.

The TIM identifies a station by the association ID that the access point assigned during the association process. This information helps the WLANterminals in making correct handover decision, in addition to the information from the comparisons of RSSI readings obtained by scanning, and thus ensures that WLAN traffic is divided more evenly between all Access Points in the area.

By increasing the beacon interval, you can reduce the number of beacons and associated overhead, but that will likely delay the association and roaming process because stations scanning for available access points may miss the beacons. You can decrease the beacon interval, which increases the rate of beacons.

This will make the association and roaming process very responsive; however, the network will incur additional overhead and throughput will go down. In addition, stations using power save mode will need to consume more power because they'll need to awaken more often, which reduces power saving mode benefits.

In an idle network, beacons dominate all other traffic. Guide to tweaking: The amount of overhead that the transmissions of beacon frames generate is substantial; however, the beacon serves a variety of functions. For example, each beacon transmission identifies the presence of an access point. How a beacon interval impacts the client By default, radio NICs passively scan all RF channels and listen for beacons coming from access points in order to find a suitable access point.

When a beacon is found, the radio NIC learns a great deal about that particular network. This enables a ranking of access points based on the received signal strength of the beacon, along with capability information regarding the network. The radio NIC can then associate with the most preferable access point. After association, the station continues to scan for other beacons in case the signal from the currently-associated access point become too weak to maintain communications.

As the radio NIC receives beacons from the associated access point, the radio NIC updates its local clock to maintain timing synchronization with the access point and other stations.

In addition, the radio NIC will abide by any other changes, such as data rate, that the frame body of the beacon indicates. The beacons also support stations implementing power saving mode. Do clients send beacon frames too?? As apposed to beacons sent out by AP's, Clients send out "probe request" frames; It's like an opposite to a beacon, clients use a probe request packets to play there role in the An A client may send a probe request frame to trigger a probe response when the client needs to obtain information from another client on the same WLAN.

A client, for instance, will broadcast a probe request when using active scanning to determine which access points are within range for possible association. Some sniffing software e. A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. Its clients hear the beacons and awaken to receive the broadcast and multicast messages.

According to the Since beacon frames are sent using the mandatory Client devices that awaken from power-save mode may find that they have to wait longer than expected to receive the next beacon frame. Client devices, however, compensate for this inaccuracy by utilizing the time-stamp found within the beacon frame. The In power-save mode, a client device may choose to sleep for one or more beacon intervals waking for beacon frames that include DTIMs.

When the DTIM period is 2, a client device in power-save mode will awaken to receive every other beacon frame. Upon entering power-save mode, a client device will transmit a notification to the access point, so that the access point will know how to handle unicast traffic destined for the client device. The client device will begin to sleep according to the DTIM period. For example, laptops may require relatively high communication throughput and may have low sensitivity to power consumption.

Therefore, a relatively low DTIM period, for example 1, may be suitable for laptops. However, cellphones may require relatively low communication throughput and may be operated by batteries of relatively low capacity.

Therefore, a relatively high DTIM period, for example 8, may be suitable for cellphones. Therefore, a medium DTIM period, for example a value of 4, may be suitable for these devices. Consequently, different client devices in power-save mode will all wake up for the same beacon frames according to the DTIM period. Currently, a network manager may need to balance the conflicting requirements for power consumption and communication throughput when in power-save mode of client devices in different wireless networks when configuring the DTIM period of an access point.

A network manager may consider the requirements of power consumption and communication throughput of client devices in a particular wireless networks when determining which DTIM period to configure for which SSID.

Unfortunately, one of the downsides of DD-WRT over traditional router firmware, is the lack of a dedicated cloud storage system.

As well as a set of unified apps and easy set-up, both Linksys and AsusWRT firmware provide this capability. While, yes it's possible to use an FTP system and set up a bunch of code, this just isn't the real deal. If you would like, you're also able to set up a DD-WRT Webserver, which allows you to host a web page, share files with colleagues, and carry out a number of other website-related activities.

I will show you the basics of getting set up with Pydio, however, you may wish to check their administration guides to see what else you can use it for. You now have an accessible webserver, which multiple people can access. If you would like it to be available from anywhere around the world, you will need to have WAN enabled in the Webserver setup. If you have your router connected to a modem, you will also need to set up port forwarding for port 81, to your DD-WRT router.

You can then find your IP by visiting our what is my IP page. Your computer and other devices on your network are identified on the internet by what is called an IP Internet Protocol address. Your ISP provides this to you automatically so most of the time you don't have to worry about it. The frequency varies by provider, but unless you have a static IP, it will change at some point in time.

When your IP does change, you won't notice any difference because it doesn't have a significant effect on the inner workings of your system. However, when you're trying to access your router from an external location then you will always need to know your IP, or you won't be able to connect to it. A DDNS system will give you a web address such as thisismyrouter. If you have already purchased or planning to a domain from NameCheap, then you'll be able to set up DDNS using their system.

We already recommend using adblockers on your computer and installing some plugins on your browser Chrome, Firefox , however, sometimes it might be more practical to run an adblocking service on your router. Unfortunately, plugins and such can be a problem on mobile devices, especially on iOS. This gives another good reason to run an Adblocker on your router directly, all devices connected to it will have advertisements blocked on it.

I am going to give you the quick and easy way of setting up Privoxy the built-in DD-WRT Adblocker and if you'd like more help you can leave a comment or visit the Privoxy websites for more details. If you have a monthly download, or upload limit assigned to you by your ISP, or would just like to know how much internet you are using, then you can analyze your data statistics using DD-WRT. Using the Status bar, you're also able to analyze a number of other factors, and find out if there are any other problems with your network as well, or improvements that could be made.

If you wish to have more in-depth network monitoring, and also see a break down of data usage by software, then I'd recommend downloading Glasswire, which will do just that and more. WPS refers to a system which allows you to easily connect a device to your router.

You might have seen it before that when you are connecting to a wireless network, it permits the option for a quick connection by pressing the WPS button on the router. Unfortunately, generally speaking these systems are horrible for the security of your router. However, there are some commercial builds, such as on Buffalo routers, where the option for it does exist. If you do get one of these, I'd recommend disabling it instantaneously.

I sincerely hope that you have enjoyed reading my guide and have found something useful to implement and help you create the best WiFi router possible. If you've never played around with DD-WRT before it's a great way to spend a few hours and improve your home with. If you have found. If you have found this guide helpful, I'd appreciate a share on your favorite social network.

And if you're having problems, feel free to leave a comment, and I'll try and help as much as possible. Looking for something? Written by Peter Selmeczy. Unfortunately not. You can easily split your traffic between networks, dedicate it to specific software, devices, and more.

Universal Plug and Play UPnP - a protocol that easily allows the sharing of devices within a network for quick and easy sharing of files, media, printers, etc. Network printers — As with hard drives, you can attach printers to your DD-WRT router which then can be accessed from across the network.

Wireless bridging — turns the router into a wireless repeater to extend the range of your WiFi signal. Advanced performance graphs — DD-WRT provides advanced network tracking and display for better troubleshooting and analysis. Adjust antenna power — one of the many ways you can increase your wireless range.

Roku Sticks and AppleTV. The first hurdle is choosing your router. DD-WRT vs. OpenWRT vs. Tomato DD-WRT isn't the only open-source router firmware on the market, and technically it isn't the best in all aspects. Do a reset. Press the reset button for 30 seconds you'll probably need a pen for this. Without letting it go, disconnect the power for 30 seconds. Plug the power back in, and keep pressing the button for a further 30 seconds.

This helps erase the memory of the router for a clean install. Connect your router to your computer with an Ethernet cable. Open your browser and type For the 'New Firmware File', choose the file you have downloaded at the start. Click Upload and wait for your router to reboot itself.

You'll be able to tell, as the lights start flashing on the front, and you'll be able to access it using the router IP address mentioned above. Do another reset. Now go to The DD-WRT default login details tend to match that of the router, but not only should you, but you will need to change this. Changing the Basic Settings Now that you've installed the firmware, the primary task will be to change all the core and important settings, including the wireless access point configuration.

As detailed in the previous instructions, you'll be prompted to change your DD-WRT username and password immediately. I recommend you write this down somewhere, such as in a password manager , so you don't get locked out by accident. If you have more than one wireless network which you will with the AC56U then give them different names so you can easily differentiate between them. Apply Settings once done. Under the Wireless Security tab, apply a password for both networks.

In Setup , I'd also recommend setting up the optional 'Router Name' and 'Hostname', but this is not essential. You should now have a functional router that you can use just like any other router on the market. Before we start the router configuration and adding bells and whistles, I'd recommend having a look around in the menus and getting a feel for the firmware.

Backing up and Restoring your DD-WRT Playing around with your router, improving the settings and enhancing its capabilities is always a lot of fun. Increasing your Wireless Range There are some principal methods for increasing your wireless range and transfer speeds.

Locating your Router The ideal way of getting optimum coverage in your home or office is by locating your router in the epicenter of the action. Use an Empty Channel While wireless frequencies are referred to as 2.

Download a Wifi Analyzer app for your device. Unfortunately, as of yet there are no good options for iOS. Use the app or software to scan your neighborhood. I found that the 5GHz channels were nearly unused, so I had my choice of options. As you can see in the image below, the 2. I was clearly using a very congested channel SuperNet and I would be better off with a higher channel number. You can also select Auto, but personally I've found that people hardly ever change their channels so this isn't required.

Advanced Wireless Settings Changing the channel, as described previously, is one of the easiest and most sure-fire ways to get a better signal. Bandwidth vs. Throughput Before I explain how to test your bandwidth and throughput , it's imperative that I explain the difference between the two. Testing your Bandwidth and Throughput Testing your bandwidth is the easiest of the two.

TX Power, Transmission, etc If after testing your settings you decided that you need a larger throughput, then you will likely start looking at changing the advanced wireless settings. Antennas and WiFi Extenders One of the quickest and easiest ways of getting better reception on your devices is by using wireless antennas.

There are three things to consider if you're going to get one: Technical Specifications. Make sure that you get one that has better technical specifications than the existing antenna. Some antennas such as the Asus WL-ANT provide increased range, but they focus the signal so this only goes in one direction. Connect by wire.

Some antennas connect to your antenna with a wire, this means that you can move it around a little. Some even have a magnetic base to make placing it elsewhere easier. There, Disable your 'Connection Type', as the router will not be plugged into your main router or modem. We recommend using the same name with a '-2' appended to it. Generally IPs get assigned to devices automatically, and you wish to avoid having a collision and cause two devices not to have a wireless signal so we'd recommend choosing a relatively high number such as Generally speaking, this should be To find out exactly which one, consult your manual for this device.

Save the changes. Go to the Security tab and turn off all the security settings uncheck everything , as your main router will handle all security. Hit Save. Once done, click Save. This means that you can plug your Smart TV, games console, or other devices to it. This will allow these devices to have a faster internet connection.

This will also allow these devices to see other devices on the network such as network attached storage solutions. If your main router has both a 2. Hit Save again. DD-WRT Overclocking Increasing your Power Like with a computer, it is possible to overclock the router so that it can perform more operations per second, and give you a better performance.

Here is how to set it up. Attach your USB storage to the router and switch it on if it isn't already. Use the USB3. Navigate to your routers WebGUI by entering Click Save and then Apply Settings. Repeat for each authorized user or less securely, directly share a single User account details with all authorized users. Plug the printer cable into the USB port of the router.

I suggest the USB2. Then Apply Settings. Have a coffee while Windows tries to detect your printer. Select your printer make and model from the list. Give your printer a name If the printer has worked so far without problems, do not worry about replacing the driver if a new version is detected.
