Title: DIR-835 - Connections problems
Post by: vpotvin on January 17, 2014, 11:21:59 AM

Hi,

I have read many post on this forum (by the way excellent job with the regular updates) and I could not really find the answer to my problem.

I've bought the DIR-835 couple of month ago and there always seem to be more and more problems. Here are the symptoms :

- Sometime, when browsing, i will click a link and it will bring me to the 192.168.0.1 home page for no reason. Then for the next 2-3 minutes, i can type any adresses and it will always bring me there. (It does that on my home computer, laptops and phones.)

- Very slow connection. Last day, the speed was very slow. When playing a game (Heartstone), there was delay for each turn played. I disconect everything and test my connection pluggues directly into the modem : everything was fine.

- My Desktop is connected with a wire, and sometime, randomly, I could be playing all night long and the next morning, when I open my computer, the connection is not working.

- Impossible to play Starcraft 2. For some reason, the rooter dosnt let me play online game, he disconnect me everytime. I have tried to configure TCP/UDP port and all those option and nothing seem to work.

These are my problems. Pretty disappoint since I paid more for this rooter, thinking I will not have those kind of problem.

In other post, you ofter ask these question, let me answer them :

What ISP Service do you have? Cable or DSL?

CABLE

What ISP Modem do you have? Stand Alone or built in router?

Stand Alone

What ISP Modem make and model do you have?

CISCO DPC3008

Thank you.

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

• What Hardware version is your router? Look at sticker under router.
• Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the routers web page under status.
• What region are you located?
• Has a Factory Reset been performed?

Internet Service Provider and Modem Configurations

• What ISP Modem service link speeds UP and Down do you have?
• 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)

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.
• 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 OFF 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 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 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 or 100Mb 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)

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
6" minimum safe distance between devices.

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 LAN PC while testing.
• Disable any downloading client software managers, i.e. Torrents or similar.

Web Browser Configurations
What browser are you using?
Try Opera or FF? If IE 8, 9, 10 or 11, set compatibility mode and test again.
Disable any security browser Add-ons like No Script and Ad-Block or configure them to allow All Pages when connected to the router.
Clear all browser caches.
