Region : Germany

Model : TL-WDR3600

Hardware Version : V1

Firmware Version : 3.13.31 Build 130320 Rel.55761n

ISP :


Hello there,
I have a WDR3600 v1 running under Firmware 3.13.31 Build 130320 Rel.55761n. A problem I recently found out about is the Wi-Fi (2,4GHz). I configured it to run with 40Mhz channel to get the full 300MBit/s, but it keeps going back to 20MHz. My Wi-Fi is "11n only" and encrypted with AES. When I reboot my router it activates 40MHz for a few seconds then switches back to 20MHz (seen that watching the reboot with inssider). Anyone got an idea what to do to keep the router from switching back to 20MHz wide channel?
Thanks in advance

Do you have a 300Mbps NIC? You can check the connection speed to check if you get the full 300Mbps. There are no setting on the utility to keep it from switching back to 20MHz on the web utility page.
