Wan and Wi-Fi icons on the D-Link Dir-300 router do not burn
Answer
Hi. WLAN and Wi-Fi are the same thing. D-Link DIR-300 has one indicator in the form of Wi-Fi antenna. You probably mean that the Wi-Fi and WAN (Internet) indicators are not lit?
I think that this is a hardware failure of the router, and it is unlikely that you can fix it yourself. And is there any sense to give it to the repair …
You can try to do a factory reset by pressing the Reset button for 10-15 seconds. But you’ve already written that it doesn’t help. Make sure you did the reset correctly. Try it again.
To go into the settings of D-Link DIR-300, to the address 192.168.0.1, you do not need the Internet. The router should just be connected to the computer.
If the address 192.168.0.1 does not open, it again indicates a failure of the router.
Most likely you will have to change the router. As practice shows, if some indicators are not lit (in your case Wi-Fi and WAN on DIR-300) or are lit/blinking differently than usual, it is a hardware failure.
