No default route on DIR-845L
« on: January 16, 2016, 06:06:19 AM »

My DIR-845L does not seem to handle my new ISP. I get an IP via DHCP but no route is created by the router - all there is is a route to my local 192.168.x.x network, nothing else and since no default route exists, I can access nothing outside of my local network. I got the IP via DHCP without issues, including DNS and gateway IP.
As a test I've connected the router to a second router - all worked fine, my DIR-845L got the IP and created the route.
I have also tried it the other way around i.e. connected a different router to my new ISP and this also worked fine, then I've connected my laptop directly to the ISP - works like a charm so it is definitely something with the 845L.

The only suspicious message in the logs is "warning: no upstream servers configured".

My hardware version is A1 and firmware 1.02 (latest). Any ideas what it might be?

Link>Welcome!

  • What region are you located?
  • Are you wired or wireless connected to the router?

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?
  • 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.
