Hi,

I am not the only one to get this issue but I didn't find the solution even if the problem has been asked several time on this forum... (eg. http://forums.dlink.com/index.php?topic=57505.0)

I am connected with the Wifi (2.4 or 5Ghz) and my problems are :
- 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.)
- Sometime I can't access for 1-2 minutes Google, Gmail or Facebook, but every other websites are working well.
- When I try to play online or to download a file, I got disconnected about every 5 minutes.

First I thought it was linked to my ISP because it is mainly the most used websites (youtube, google, facebook) but without the routeur it is working like a charm!
I checked all the option on the routeur config page but didn't find anything weird...(last firmware 2.06WW, QoS off, DHCP on and IPs are ok on each devices, DNS has been checked as well...) and my modem looks ok as well using DHCP...

I guess you are going to ask me these kind of really stupid questions such as which OS are you under... Do you use IE or Chrome... ^^ Is your router in a hoven... ^^
Let me tell you that I am an IT Engineer and my computer is pretty well configured, last driver...And everything was working fine before setting up the new routeur.
On top of that I got the same problem on every devices at home (a MAC laptop, Android Tablet, Mobile Phone...) which were working fine with the previous routeur! But this one doesn't work and I don't understand!

Last but not least, when I don't have any problem my internet speed is just normal, with or without the routeur I get the same speed.


Thanks in advance for helping me

Link>Welcome!

• What Hardware version is your router? Look at sticker under router.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?

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

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 off 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.

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy

• Ensure the default (dlink) SSID name is changed. Can be anything and not something that's already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N on 5Ghz?
• Channel Width set for Auto 20/40Mhz or try 20Mhz only.
• Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
• What wireless devices do you have connected?
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by?[/b]
• Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
• If you have any of these options, Try turning OFF or ON Short GI, WLAN Partition, Extra Wireless Protection and HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless.

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."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

PC 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.

"Is your router in a hoven..." <<<Whats this?

[massacreur]

I already answered some of these questions...
Hardware B1
Firmware 2.06WW
Cable between box and routeur is Ok

The funny sentence about the hoven was to post answer your placement part...So nothing wrong on this side.

I tried the different configuration and I still have the same problem but not only, now my internet connexion is also way slower... !
I think it is link to the DNS as now instead of getting connected directly to the ones of my ISP, I am connected to the Google ones. However, the connexion with Google is one of the weirdest ever, sometimes it works very fast and sometimes I should get some hugh time out! TIme out I don't have when I am connected directly to my modem.

[FurryNutz]

You might try using NameBench to see if there are faster ones out there. Google maybe heavily used and may not always be the fastest.

What region are you located?
What ISP Modem Mfr. and model # do you have?

[massacreur]

Ok I tried with another DNS and get the same problems...
It is just like if I was disconnected very often, I lost my connection every 2 minutes??? But still connected to the Wifi.

Otherwise I don't know my ISP, I need to see with my leaser and I live in Sydney, Australia.

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.
Let us know how it goes please.

[massacreur]

Alright let's do that

Thank you for your time
