Hi,

I need some help with my DIR-850L router. It was working fine last night but suddenly it stopped working. I tried to fix it by doing the set-up again but it did not fix it. So I tried to update my firmware - FW: 2.06, HW: B1. I am based in Surrey BC, Canada. My internet provider is Lightspeed. What should i do to fix my issue? Hope you guys can help. Thank you.

Link>Welcome!

• Are you wired or wireless connected to the router?
• Has a Factory Reset been performed?

Internet Service Provider and Modem Configurations

• What ISP Modem Mfr. and model # do you have?
• 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
• 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.
  Example of a D-Link router configured for PPPoE with ISP Modem bridged: PPPoE Configuration on a Router

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. 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. I recommend having the ISP service physically check the lines going from the out side 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.

Any status on this?

Hi FurryNutz,

Thank you for replying to me immediately regarding my issue. I saw your reply but wasn't able to respond back, my apologies for that. So after I logged my issue here which was on May 25 at 2 am, I went to bed with the internet not fixed. When I woke up, the internet was back on and the internet light was now yellow and not orange. I am not sure what happened but I was glad to know that it was resolved already.

The things I did though were to upgrade the firmware of my wifi router, then I re-installed it again. I was hooked to the router directly via LAN cable. My ISP is Lightspeed and my speed is 25 mbps. I also have an ADSL subscription. I do not have the details of my ISP modem and mfr. but I can provide it later if needed. I know I bought it from them and the brand was probably OV link or something like that. I can check it again.

My internet seems to lag a little or get hang up. I observed this recently when browsing sites or opening apps. I am not sure if it is my ISP or my router. I also checked my internet speed via fast.com on my mobile phone and found that the speed is not consistent. So I am still keeping an eye on it for now.

Anyhow, thank you again for your help and excellent advice. If you need more info from me, please let me know.

Regards,
Sioty

Seems that this maybe a ISP service or ISP modem issue if you came back later and the router was connected and you got internet service.
