The D-Link Wireless N 300 Router (DIR-615) is ideal for upgrading your existing wireless home network. With QoS (Quality of Service) bandwidth optimization to analyze and separate multiple data streams, the DIR-615 has the smarts to handle multiple wireless devices and enable smooth streaming across your entire home network. Upgrading your home network to Wireless N 300 provides an excellent solution for sharing an Internet connection and files such as video, music, photos, and documents. Not only does the D-Link Wireless N 300 technology extend your wireless range, it’s also backwards compatible with previous-generation wireless devices.

D-Link DIR-615 Wireless Installation Considerations

D-Link DIR-615 Wireless Installation Considerations

The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within the operating range of your wireless network. Keep in mind that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:

1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum – each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.

2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.

3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on range. Try to position access points, wireless routers, and computers so that the signal passes through drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.

4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.

5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), your wireless connection may degrade dramatically or drop completely. Make sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits a signal even if the phone in not in use.

Quality of Service (QoS) enhances the experience of using a network by prioritizing the traffic of different applications. A QoS Rule identifies a specific message flow and assigns a priority to that flow. For most applications, the priority classifiers ensure the right priorities and specific QoS Rules are not required. QoS supports overlaps between rules. If more than one rule matches a specific message flow, the rule with the highest priority will be used.

QoS (Quality of Service):

Enable this option if you want to allow QoS to prioritize your traffic Priority Classifiers.

HTTP:

Allows the D-Link DAP-2553 access point to recognize HTTP transfers for many common audio and video streams and prioritize them above other traffic. Such streams are frequently used by digital media players.

Automatic:

When enabled, this option causes the access point to automatically attempt to prioritize traffic streams that it does not otherwise recognize, based on the behavior that the streams exhibit. This acts to de-prioritize streams that exhibit bulk transfer characteristics, such as file transfers, while leaving interactive traffic, such as gaming or VoIP, running at a normal priority.

dap-2553-QOS

Name: Enter a name for the new QoS rule in the field provided.

Priority: Use the drop-down menu to select the desired priority: Background (BK), Best Effort (BE), Video (VI), or Voice (VO).

Protocol: Use the drop-down menu to choose the appropriate protocol used by the messages: Any, TCP, UDP, Both, IMCP, or Other.

Host 1 IP Range: The rule applies to a flow of messages for which one computer’s IP address falls within the range set here.

Host 1 Port Range: The rule applies to a flow of messages for which host 1’s port number is within the range set here when the Protocol is set to TCP, UDP, or Both.

Host 2 IP Range: The rule applies to a flow of messages for which the other computer’s IP address falls within the range set here.

Host 2 Port Range: The rule applies to a flow of messages for which host 2’s port number is within the range set here when the Protocol is set to TCP, UDP, or Both.

FIREWALL PROTECTION & QoS

Security features prevent unauthorized access to the home and office network from wireless devices or from the Internet. The ADSL2+ Modem with Wireless N300 Router provides firewall security, such as Stateful Packet Inspection (SPI) and hacker attack logging. SPI inspects the contents of incoming packets before they are allowed in, while hacker logging helps to protect your network against Denial of Service (DoS) attacks. For Quality of Service (QoS), the router prioritizes traffic to enable a group of home or office users to enjoy the benefit of a smooth network connection without concern of traffic congestion.

The wireless router portion supports 802.11n speeds up to 300 mbps and is backwards compatible with older WiFi specifications as well. The router is IPv6 ready and has a number of security and speed enhancements over older products in the line. The router has WPA/WPA2 and WEP data encryption.

QoS (Quality of Service) is designed to “shape” and prioritize your internet traffic among the computers on your LAN. This allows for an optimized internet experience.

To set up QoS in your router, use the following steps(D-Link DIR-625 as a example):

Step 1: Open a web browser and type the IP address of the DIR series router into the address bar (default is http://192.168.0.1).

Step 2: The default username is admin (all lower case) and the default password is blank (nothing). Click on OK.

Step 3: Click on the Advanced tab at the top and then click on QOS Engine on the left hand side.

dlink-QOS

Step 4: Ensure the Enable QoS Engine box is checked. Also ensure that the Automatic Classification and Automatic Uplink Speed boxes are checked as well as.

Step 5: Under QOS Engine Rules, fill in the required information for the QoS rule as follows:

Make sure to click the check mark next to the rule to enable it.

  • Name – Create a name for the rule that is meaningful to you. (this identifies, to the user, which rule is being configured)
  • Priority – Assign the rule a priority. (1 being highest and 255 being lowest).
  • Protocol – Define a protocol number and/or type. (e.g. for streaming media you would use UDP and for FTP you would use TCP)
  • Source IP Range – Assign the local IP address range. (This tells the router what IP addresses on the LAN are to use the given QoS rule)
  • Source Port Range – Define the ports that you want prioritized. (e.g. Web traffic (http) operates on port 80.)
  • Remote IP range – Assign a remote IP address range. (Unless you are positive of the remote IP address range you want prioritized, leave this at it’s default setting. 0.0.0.0 to 255.255.255.255)
  • Destination Port Range – Assign a remote port range. (Unless you are positive of the remote port range you want prioritized, leave this at it’s default setting. 0 to 65535)Step 6: Click Save Settings.
