101D-Link DWR-755 User ManualSection 5 - Troubleshooting3. Why can’t I connect to certain sites or send and receive emails when connecting through my router? If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and Hotmail, we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc). To nd the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be another computer, or a URL. • Click on Start and then click Run. • Windows® 95, 98, and Me users type in command (Windows® NT, 2000, XP, Vista®, and 7 users type in cmd) and press Enter (or click OK). • Once the window opens, you’ll need to do a special ping. Use the following syntax: ping [url] [-f] [-l] [MTU value] Example: ping yahoo.com -f -l 1472
102D-Link DWR-755 User ManualSection 5 - TroubleshootingYou should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (1452+28=1480). Once you nd your MTU, you can now congure your router with the proper MTU size.To change the MTU rate on your router follow the steps below: • Open your browser, enter the IP address of your router (192.168.0.1) and click OK.• Enter your username (admin) and password (blank by default). Click OK to enter the web conguration page for the device. • Click on Setup and then click Manual Congure.
103D-Link DWR-755 User ManualAppendix A - Wireless BasicsD-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard, the D-Link wireless family of products will allow you to securely access the data you want, when and where you want it. You will be able to enjoy the freedom that wireless networking delivers.A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless LANs are used increasingly in both home and oce environments, and public areas such as airports, coee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eciently. Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial for many users. Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop and desktop systems support the same protocols as Ethernet adapter cards. Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless router is a device used to provide this link.Wireless Basics
104D-Link DWR-755 User ManualAppendix A - Wireless BasicsWhat is Wireless?Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or oce network.Why D-Link Wireless? D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products. D-Link delivers the performance you need at a price you can aord. D-Link has all the products you need to build your network.How does wireless work? Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But wireless technology has restrictions as to how you can access the network. You must be within the wireless network range area to be able to connect your computer. There are two dierent types of wireless networks Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).Wireless Local Area Network (WLAN)In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and many other outdoor venues.Wireless Personal Area Network (WPAN)Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to 30 feet away.
105D-Link DWR-755 User ManualAppendix A - Wireless BasicsCompared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other devices that operate on batteries.Who uses wireless?

106D-Link DWR-755 User ManualAppendix A - Wireless BasicsWhere is wireless used? Wireless technology is expanding everywhere not just at home or oce. People like the freedom of mobility and it’s becoming so popular that more and more public facilities now provide wireless access to attract people. The wireless connection in public places is usually called “hotspots”.Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations like: airports, hotels, coee shops, libraries, restaurants, and convention centers.Wireless network is easy to setup, but if you’re installing it for the rst time it could be quite a task not knowing where to start. That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless network.TipsHere are a few things to keep in mind, when you install a wireless network.Centralize your router or Access Point Make sure you place the router/access point in a centralized location within your network for the best performance. Try to place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home. If you have a two-story home, you may need a repeater to boost the signal to extend the range.Eliminate Interference Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access point. This would signicantly reduce any interference that the appliances might cause since they operate on same frequency.Security Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.
107D-Link DWR-755 User ManualAppendix A - Wireless BasicsThere are basically two modes of networking: • Infrastructure – All wireless clients will connect to an access point or wireless router.• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer, such as two or more DWR-755 wireless network Cardbus adapters.An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the wireless router or access point. An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in Ad-Hoc mode to communicate.Wireless Modes
108D-Link DWR-755 User ManualAppendix B - Networking BasicsNetworking BasicsCheck your IP addressAfter you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.Click on Start > Run. In the run box type cmd and click OK. (Windows® 7/Vista® users type cmd in the Start Search box.)At the prompt, type ipcong and press Enter.This will display the IP address, subnet mask, and the default gateway of your adapter.If the address is 0.0.0.0, check your adapter installation, security settings, and the settings on your router. Some rewall software programs may block a DHCP request on newly installed adapters.
109D-Link DWR-755 User ManualAppendix B - Networking BasicsStatically Assign an IP addressIf you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below:Step 1Windows® 7 - Click on Start > Control Panel > Network and Internet > Network and Sharing Center.Windows Vista® - Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Manage Network Connections.Windows® XP - Click on Start > Control Panel > Network Connections.Windows® 2000 - From the desktop, right-click My Network Places > Properties.Step 2Right-click on the Local Area Connection which represents your network adapter and select Properties.Step 3Highlight Internet Protocol (TCP/IP) and click Properties.Step 4Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN IP address on your router. Example: If the router´s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X where X is a number between 2 and 99. Make sure that the number you choose is not in use on the network. Set the Default Gateway the same as the LAN IP address of your router (I.E. 192.168.0.1). Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The Secondary DNS is not needed or you may enter a DNS server from your ISP.Step 5Click OK twice to save your settings.
