slow dhcp

Hi.

Since i have my RT-AC86U router i have problems with my 2 windows laptops. One is connected with lan cable and the other one with wifi. The one with the lan cable has the biggest problems, it takes sometimes up to 5 minutes before i receive a ip adress. Because i flashed the merlin firmware directly on my new router I'm not sure if it is merlin related or not.

I tried a few things to find the problem:
The ipconfig /release and renew gave me this:

An error occurred while releasing interface Ethernet : An address has not yet been associated with the network endpoint.

An error occurred while renewing interface Ethernet : The name specified in the network control block (NCB) is in use on a remote adapter.
The NCB is the data.


The windows trouble shouters comes with this message: Ethernet doesn't have a valid IP configuration.

I made also a log with wireshark. This is more or less repeating its self until it gets an ip address.

My router ip is 192.168.1.1 and my laptop is 192.168.1.71. They are connected trough each other with an switch which has 192.168.1.12

Power down your entire network and physically remove power cables, USB cables, LAN cables and any other connection you can and leave it like that for 10 minutes or so (this is including the modem/ONT and the router and switches too).

If it was a static build-up, this should resolve your issues.

I tried your solution half an hour ago. Keep you updated about the results.
