Title: Resolving Host Problem
Post by: skanungo on September 21, 2013, 12:21:25 AM

I am using D Link DIR 600L router. I have a cable broadband connection (no modem). Whenever I start my PC I have to wait at least for 5-7 minutes for the router to get ready. For such a long time the web browsers keep on showing Resolving Host, no matter what browser I use. After the delay everything works fine.

If I directly plugin the cable to CPU everything works fine. Problem arises as soon as use the net via router.

I have called Dlink Support Team several times and they have accessed my PC remotely and said all the settings are fine and the router is also fine but they are unable to understand why this happening.

I have tried to disable Anti Spoofing and SPI mode in Firewall settings but that does not seem to resolve the issue. In the setup I have copied MAC address and also specifically mentioned DNS. I have tried with some public DNS as well as the DNS which my ISP has provided.



Please note that I am absolutely novice about these router settings. Please help me. Thank you in advance.

My Hardware version is Bx and firware version is 2.01.
Previously it was 2.00. Dlink Support Team provided a file to upgrade the firmware. Still the same issue. Also with this firmware version I am unable to check the router's log file as when I click STATUS tab everything becomes ghost.

Welcome! (http://forums.dlink.com/index.php?topic=41537.0)

• What region are you located?
• Are you wired or wireless connected to the router?
• Has a Factory Reset been performed?
• Was a Factory Reset performed before and after any firmware updates then set up from scratch?

Internet Service Provider and Modem Configurations

• What ISP Modem service link speeds UP and Down do you have?
• If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT (http://www.practicallynetworked.com/networking/fixing_double_nat.htm) and How NAT Works (http://cognitiveanomalies.com/cisco-nat-how-nat-works/). To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values (http://forums.dlink.com/index.php?topic=53008.0)
• For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.

• Turn off ALL QoS (http://vonage.nmhoy.net/qos.html) or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS (http://en.wikipedia.org/wiki/Quality_of_service) or Gamefuel.
• Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
• Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
• Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0)
• Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
• Ensure devices are set to auto obtain an IP address.
• If IPv6 (http://en.wikipedia.org/wiki/Ipv6) is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
• Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI (http://en.wikipedia.org/wiki/SPI) to test.
• Enable uPnP (http://en.wikipedia.org/wiki/Upnp) and Multi-cast Streaming (http://en.wikipedia.org/wiki/Multicast) under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
• Turn off WISH, and WPS under Advanced.
• WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
• Set current Time Zone, Date and Time. Use an NTP Server (http://forums.dlink.com/index.php?topic=48695.0) feature. Tools/Time.

• Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. (http://en.wikipedia.org/wiki/CAT6)

3rd Party Security Software Configurations

• Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
• Turn off all devices accept for one wired PC while testing.
