router not connecting to internet after a power loss or sag
« on: September 23, 2015, 04:57:15 AM »

I've had this router for about 2 months and twice I have experienced a momentary power loss that causes the router to lose the internet connection. Power cycling the router does not reset the condition. I have tried restoring my settings and that doesn't work either. The first time this occurred I had to go through the entire setup procedure to get my connection back. So far that hasn't worked and this time I'm stuck with a non functional router, it's a brick at this point. I am on a DSL modem and the router is connected directly to it. I had a D-Link several years ago that got bricked when it received a firmware push. I switched to another brand that served me well for 7 years until it no longer would wake up. I decided to give D-Link another chance and only 2 months into ownership I'm feeling that I again made a bad choice. I would prefer to not have to connect this router o a UPS. Any assistance would be greatly appreciated.

So power cycling BOTH modem and router doesn't help? (Wait for modem to attach then power on router).

There are devices to do that but I've never used one ( 3gstore i think has). I do have my router and modem on separate ups devices though. And its not a dsl modem. How long does it take your dsl to come online. That might be the problem.

Link>Welcome!

  • What Hardware version is your router? Look at sticker under the router case.
  • Link>What Firmware version is currently loaded? Found on the routers web page under status.
  • What region are you located?
  • Are you wired or wireless connected to the router?
  • Has a Factory Reset been performed?

Recommended procedure to update any routers FW. Link> >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? Link> Speed Testing Sites
  • By-pass the main host router and check internet connection by connecting a wired LAN PC directly to the ISP modem to verify connection access and ISP speeds.
  • 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

I was successful in getting the router back working again. Here's what I did:
1. I tried to connect thru the router directly to my DSL modem  NG
2. Pulled the cable (Internet cable) from the DSL modem out of the router an plugged it directly into the PC Success  (wire's good)
3. Reconnected the Internet cable to the router with the PC connected NG - solid amber internet indicator on router
4. Logged into the router from the PC and initiated the Internet Connection Wizard message 'Router is unable to detect your Internet type' window popped up
5. In the 'Please select your Internet connection below' window, I deselected then reselected (toggled between PPPoE and DHCP) Voila!
I should technically have the PPPoE selection enabled, but when I originally setup the router in August I just let it do it's own thing. It worked fine at the outset. My concern at this time is the fact that restoring the settings didn't work. I again saved the configuration. The only thing that kinda makes sense is that my DSL modem and this router don't play nice together after a power problem, or the router firmware is suspect.

Thanks for your quick response.

  • What ISP Modem Mfr. and model # 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
  • 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. Call the ISP and ask to see if the ISP modem can be bridged. 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.
