I remember having multiple problems with TP-link router; it was its DHCP server function that wouldn’t turn off no matter what. Here’s what I finally did:
- Log to your TP-link router and update it to the latest firmware.
- Connect your laptop to it directly – turn your laptop’s WiFi off and connect via cable. Release/renew ipconfig
- Check TP-Link IP address and point browser to it; go to administration/configuration screen.
- Before switching it to the “WiFi client mode”, disable DHCP. This is important, because DHCP options are disabled in the client more but DHCP stays on.
- Switch TP-Link to the client mode and configure it.
- Plug OS back to TP-link.
- If you are using static IP address on OS, it should work now, however, mine is configured to use dynamic IP, so the following steps required:
- On your Asus router, go to Lan->DHCP server – IP reservation
- Add your OS mac address (most likely it’s 00:69:69:2D:30:00) and assign whatever IP you like
- Make sure port forwarding works
Most important thing was disabling TP-Link’s DHCP in the client mode. In my case. TP-Link is so unreliable and messy, I’m considering replacing it with power-line network adapter – after all, the power outlet is right there.
