Frequent disconnection with DIR-645
« on: July 02, 2014, 10:50:57 AM »

Hello, I have to say sorry about my bad English first, since it is not my first language.

I had bought my DIR-645 for more than a year, or two...can't remember, to amplify the signal strength in my house. I had another modem from Netgear working alongside with the D-link one.

For me, I did not use the D-link one that often since it has the disconnection frequently, so I can't play any online game with it. Therefore, most of my time is on Netgear, until recently this thing has some problems occurred. Then I switched back to use the D-link, and the frequent disconnection still troubles me. Disconnecting like every 30 or 40 minutes. I have read a similar post to my problem, and I still did not get this fixed.

As I am not quite familiar with router and modem stuff, I really need some help from everyone of you.

My ISP is Optus in Australia, and it's a DSL service, which directly connected to the Netgear modem (Device Name: Netgear Wireless Cable Voice Gateway EMTA CG3000-1STAUS). And it extended to DIR-645 with cable.

Connection Type : DHCP Client
Cable Status : Connected
WAN Failover Status :
Network Status : Connected       
Connection Up Time : 0 Day 0 Hour 4 Min 37 Sec
MAC Address : c8:be:19:8f:6e:23
IP Address: 192.168.0.10
Subnet Mask : 255.255.255.0
Default Gateway: 192.168.0.1
Primary DNS Server : 204.194.232.200
Secondary DNS Server : 204.194.234.200

*Please explain to me as clear and easy as possible, cus I am stupid with these stuff  :P*
thank you very much

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.

Can you re-confirm that your using DSL or cable ISP services? The modem you listed is a Cable modem, not a DSL modem:
http://support.netgear.com/product/CG3000-1STAUS#wrapper

Are you using the 645 as a wired AP mode or in main host router mode? Connecting the ISP modem to the Internet port on the back of the 645 or LAN port?

Internet Service Provider and Modem Configurations
  • 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 Router

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 Routers only: Try single mode G or N or mixed G and N?
  • 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.
  • 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?
  • 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.

Is there WiFi enabled on the ISP Modem/Router as well?  ???

I...actually still having the same problem, but I don't know where to find the answer for most of your questions.

But you are right, I am currently on cable service, it was my bad remembering the old days stuff (was using DSL service not long ago).

Therefore, I try to solve it in other way (not sure if it works). I am now working with my ISP to see if we can change back to a DSL service, since my home changed to cable service for like 1.5 year and it was working fine at those days.

And again, sorry about lacking knowledge of router and modem stuff :(

I am trying my best to answer your questions.

•Is ISP Modem/Service using Dynamic or Static WAN IP addressing?

no idea, can't find anywhere showing this option

•What ISP Modem service link speeds UP and Down do you have?
how to check?

•Check cable between Modem and Router, swap out to be sure.
Check later

•Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.

It seems like 1502 (1474+28?)

•For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
So mine is a cable service, this question is not available, right?

• 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.
ISP modem's WAN IP Address 58.107.113.42
645's WAN IP Address is 192.168.0.10
And I did not get the rest of the content.

•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.
It has been changed since the first day using it.

•What wireless modes are you using?
802.11 Mode : Mixed 802.11n, 802.11g and 802.11b <- Is that this thing?

•2.4Ghz Routers only: Try single mode G or N or mixed G and N?
not sure how to check whether it is 2.4Ghz or 5Ghz router

I will do the rest later, since there is someone else using the internet. Will catch up with you soon. Once again, sorry about this late follow up.

You need to bridge the ISP modem or input the 645's WAN IP Address is 192.168.0.10 into the ISP modems DMZ.

Talk to your ISP and ask about bridging the ISP modem or use the DMZ. You'll need to refer to the ISP for help with the ISP modem.

Let us know how it goes.
