DIR-842 Rev C Firmware v3.10B05 Released
« on: August 14, 2018, 02:45:54 PM »

Firmware version 3.10B05 released. This fixed the DNSmasq security vulnerability.

Note there are 2 firmware files. You must upgrade to the "middle" file first, and then to v3.10B05.

Firmware version 3.10B05 released. This fixed the DNSmasq security vulnerability.
Note there are 2 firmware files. You must upgrade to the "middle" file first, and then to v1.10B05.
==============================================================================================
Would you help that I missed to upgrade the "middle" file first and directly upgrade to 3.10B05. How can I reset to 3.02 or any suggestions to do now? Thanks.

I am not sure if this wrong upgrade caused the network speed slow down greatly. I got rather good speed before upgrade, but now the speed is not acceptable. can someone help?

Link>Welcome!

  • What region are you located?
  • Are you wired or wireless connected to the router?
  • Was a Factory Reset performed before and after any firmware updates then set up from scratch?

How are you speed testing?
  • 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. Power OFF the ISP modem and router for 1 minute then power ON the ISP modem. Then power ON the router.

How are you speed testing? I didn't do speed testing, just found a running circle frequently show and the film was heavily lagging after the change of firmware.
What ISP Service do you have? Cable or DSL? I guess DSL
What ISP Modem Mfr. and model # do you have? Sorry that I don't know
Is ISP Modem/Service using Dynamic or Static WAN IP addressing? Sorry that I don't know
What ISP Modem service link speeds UP and Down do you have? Link> Speed Testing Sites, Sorry that I don't know
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. Power OFF the ISP modem and router for 1 minute then power ON the ISP modem. Then power ON the router. my NB has no LAN port hence I can only use wireless to connect to the router.

I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this.
Link> Tech Support Contact Information
We find that phone contact has better immediate results over using email.
Let us know how it goes please.
