Section 9 - Troubleshooting Troubleshooting This chapter provides solutions to problems that can occur during the installation and operation of the DIR-840. Read the following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a different operating system, the screenshots on your computer will look similar to the following examples. 1. Why can’t I access the web-based configuration utility? When entering the IP address of the D-Link router (192.168.89.
Section 9 - Troubleshooting • Configure your Internet settings: • Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the button to restore the settings to their defaults. • Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make sure nothing is checked. Click OK. • Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
Section 9 - Troubleshooting 3. 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 find 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.
Section 9 - Troubleshooting You 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 find your MTU, you can now configure your router with the proper MTU size.
