[AC68R]Can't change Channel bandwidth under 2.4GHz

[ronan_zj]

I think there is another problem with 205 build, because I can't change the Channel bandwidth to 20/40MHz under 2.4GHz, and I have tried both "Reducing USB3.0 interference" on and off.

I did another check, the router can not change bandwidth to either 20/40 or 40MHz under 2.4G, and I can change the bandwidth under 5G without problem. So I guess I get a Defective Product?
Could anyone confirm your router can use 20/40 bandwidth with 205 built?

Are you manually selecting a channel or is it on auto?

I just back from Bestbuy with a new replacement, and I am still having the same problem on the old FW 158.
I have done both way, and I am still stuck on 20MHz, so I am not sure if I did anything wrong on the setup.
I have guest network 1 on, and its WEP-128bit.
Both 2.4G and 5G are WPA2-Personal encryption

I have no problem to change channel bandwidth under 5G, but I have no luck on 2.4G

I can confirm I see the same issue in the firmware. Development has been made aware and it should be fixed in the firmware update next week.

Thank you for the confirmation.
