Title: frequent internet drop off
Post by: happyface on August 22, 2013, 11:48:47 AM
Hello there,

I bought a DIR 615 recently to replace my old DIR 601. I didn't feel internet speed or wireless coverage obvious improvement as I expected. Another problem is now I have frequent internet drop off, especially in the evening, about 2-3 times every night. Most of the time it will reconnect automatically, a few I'll have to power off and on router. I use Acanac cable internet with 25MGPS unlimited. I have a desktop PC wired after router and 3 laptops using wireless. Other wireless includes iTalk TV and cellphones, but most won't be used at the same time. We don't play computer games, neither movie fans, so I think the usage is not that heavy. Any suggestion would be appreciated. Thanks a lot.

Internet Service Provider and Modem Configurations

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.

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.

Web Browser Configurations
What browser are you using?
Try Opera or FF? If IE 8 or 9, set compatibility mode and test again.
Try turning off these features in Chrome:
Top right corner, little bars for options > Settings > Settings (on left) > Show advanced settings.
Uncheck these:
Use a web service to help resolve navigation errors
Use a prediction service to help complete searches and URLs typed in the address bar
Predict network actions to improve page load performance
Enable phishing and malware protection


I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. 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. 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.

Hello, Thank you for your quick reply !!!
My H/W Ver.: l1
F/W Ver.: 9.03NA.
I live in scarborough, M1J2L7.
I haven't try factory reset.
I have a new Huawei MT 130U cable modem bought directly from Acanac, which is my internet provider and configulated.
Thank you so much for your detailed instruction. An outsider like me can modify settings for a router, feel really cool. I did exactly as told but there are several things I couldn't find on my router. such as: no Endpoint Independent for TCP and UDP selection in Firewall settings;  no WISH, and WPS in Advanced networking.
The WAN port speed in Auto 10/100mbps.
I choose NTP server: ntp1.dlink.com.
Because I am not sure the wireless mode for all my devices, so I choose mixed 802.11 n and g.
channel width: auto 20/40 mhz.
I couldn't figure out how to set a manual Channel to an open or unused channel, not such item.
I mainly use firefox.
Could you please tell me how to check signal levels going to the ISP modem? I also wonder whether the internet provider's cable speed be lower than expected. My cable connects directly from outside to my modem, then router. I don't have TV spliter, it is wireless iTalk TV.
It is 11pm right now and I did most as you told me after dinner. So far we had once internet drop off. Will update tomorrow because my daughter will keep using computer for a while, to see whether it will drop again.

Thank you so much for your help

Have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem.

Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?

Try a factory reset at some point when you have time.

Are you in the North American or EU region?

You'll need to contact your ISP and have them help you check signal levels.

Keep us posted...
