Admin password is changed repeatedly!!!

Hi there,

My router model is R7000_v1 and has been upgraded to the latest firmware R7000-V1.0.11.208.chk, and has been turned off remote administration.

I've flashed Merlin firmware before, but someone hacked in and changed the admin password (very strong) . So I re-flashed the latest Netgear firmware R7000-V1.0.11.208.chk

However, my router was still repeatedly hacked and changed the admin password and wifi password (very strong!!!) , no matter how many times I changed the admin password and wifi password.

Please note that this is the latest firmware R7000-V1.0.11.208.chk and I has already turned off remote administration.

I'm going out of my mind. Can someone please give me some advice?

Below is the same question in Chinese.

我的路由器型號是 R7000 v1，已經升級到最新固件 R7000-V1.0.11.208_10.2.101.chk ，并且已經關閉了遠程管理。

之前曾經刷過梅林固件，由於被人入侵並修改了admin密碼（密碼很强），於是刷了最新的Netgear固件 R7000-V1.0.11.208_10.2.101.chk

但是，我的路由器仍然被人反復入侵，被修改了admin密碼和wifi密碼（密碼很强！！！），不論我重新修改了對少次很强的admin密碼和wifi密碼。

請注意，已經是最新固件 R7000-V1.0.11.208_10.2.101.chk，并且已經關閉了遠程管理。

我快要瘋了，有人可以給一些建議嗎？
