My dir-657 drops the DNS when downloading and at random.
« on: February 22, 2015, 03:44:05 AM »

When I am downloading though steam or a torrent program my router suddenly doesn't allow me to connect to websites. I tried changing the DNS the router uses to google's but still the same thing. When I contacted the ISP they weren't of much help as well. On a side note my previous router worked perfectly with the exception of the download/upload speed it had. When the DNS drops the wireless network also stops working. I updated the firmware to 1.0.2 and nothing has changed.

Link>Welcome!

  • 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?
>FW Update Process

    Internet Service Provider and Modem Configurations
    • What ISP Service do you have? Cable or DSL?
    • What ISP Modem Mfr. and model # do you have?
    • Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
    • What ISP Modem service link speeds UP and Down do you have?
    • Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.
    • Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
    • For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
    • If the ISP 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 and 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. Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address of 192.168.0.1. Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the DIR router to 192.168.1.1 or .0.254.
      Example of a D-Link router configured for PPPoE with ISP Modem bridged: PPPoE Configuration on a Router

    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.

    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 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 on DNS Relay  under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench and input new DNS addresses under Setup/Internet/Manual.
    • 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 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 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 to test.
    • Enable uPnP and Multi-cast Streaming 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 feature. The DST setting is only needed in the NA region. Tools/Time.
