Not Connected to The Internet Resolved by Upgrading D-LINK DIR-600M Home Router's Firmware

My home internet is using D-LINK DIR-600M router. This router has 4 ethernet ports for client, 1 ethernet port connected to fiber optic modem (or any other modem) and wireless connections for laptop and mobile devices.

There is 1 annoying problem with this router, sometimes my wireless clients cannot get in to the internet although it still connected to the router's wireless network. When this is happen I disabled and enabled wireless connection and this works fine.  Although this is fine with me but not for other family members, they don't know how to disable and enable wireless, they have to restart the computer when this is happen and this is not good at all.

One that I can do to resolve this problem is to upgrade it's firmware. I already looking for firmware for my router DLINK DIR-600M but it's not easy. There is not much result on search engine.

After browse through all search engine result from position number 1, I decided to download it from Softpedia. The file is 1.23MB and contain 1 pdf file and the firmware image itself. Here step to upgrade the firmware:
1. Using only cable to the router, don't use WIFI.
2. Extract the file to the folder where you can find it easily, I extract to desktop.
3. Login to your router, the default IP address is

4. Login using administrator account, username is Admin and without password (blank).
5. Make sure current firmware version is lower than you want to upgrade. In my case the current version is 3.01
6. Click Maintenance tab, Firmware Upgrade, Click choose file and browse  to file DIR-600M C1_v3.05ENB01_beta_20170306.img
7. Click upload it takes only several seconds and the upgrade process finish. The router will restart in 60 seconds.

8. I forgot to save the router's configuration, luckily the configuration still there not change, this is good, some router will reset it's configuration after firmware upgrade.
In case you need the file, I put it here
After firmware upgrade I never found the same problem again.
