• Are you wired or wireless connected to the router?
• Has a Factory Reset (http://blog.dlink.com/what-is-a-reset-button-when-should-i-use-it) been performed?
• Was a Factory Reset performed before and after any firmware updates then set up from scratch?

• What ISP Modem Mfr. and model # do you have?
• What ISP Modem service link speeds UP and Down do you have? Link> Speed Testing Sites (http://forums.dlink.com/index.php?topic=48352.0)
• By-pass the main host router and check internet connection by connecting a wired LAN PC directly to the ISP modem to verify connection access and ISP speeds.
• Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. (http://en.wikipedia.org/wiki/CAT6)
• 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)

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. I recommend having the ISP service physically check the lines going from the out side to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.

• What ISP Modem Mfr. and model # do you have?

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. Besure to log into the Admin account on 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).
• 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 or Disable Use Unicasting (compatibility for some ISP DHCP Servers) and test under Setup/Internet/Manual. Disable may help with speed performance on higher speed ISP services.
• Turn off DNS Relay (http://forums.dlink.com/index.php?topic=45143.0) under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0) and input new DNS addresses under Setup/Internet/Manual.
• Setup DHCP (http://forums.dlink.com/index.php?topic=58017.0) 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 and maintain consistency for applications that need to connect as well as mapped drives.
• 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 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.
• Turn off WISH (http://forums.dlink.com/index.php?topic=40459.0), 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. The DST setting is only needed in the NA region. Tools/Time.

If this router is provided by your ISP or, owned and maintained by Jupiter Networks, they may be the ones to contact if they maintain and develop FW for this model HW. Even thought it may say D-Link on the unit, some ISPs maintain and develop FW for D-Link HW. You'll need to contact them and talk with them about FW and help and information regarding this. Putting OEM FW on it may cause problems or violate ISP use policies. Ask first about this.

If you need additional help and information, I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email. We do not have FW resources here in the forums.

Let us know how it goes please.

Ok just making sure.

I recommend contacting your regional D-Link support office and ask about FW. I don't see any FW listed on there web site so I don't know where it would be located, if there is any: http://www.dlink.co.in/products/?pid=DIR-600M (http://www.dlink.co.in/products/?pid=DIR-600M)

Run thru the suggestions and see if anything helps. If not, and if any FW can be found and updated and you still exhibit problems with the router, then the router maybe faulty and would need to be RMAd or replaced.

Please use this for doing any FW updates:
