The N900 launched by Western Digital is actually a time capsule, which is essentially a router+1T hard disk. The Chinese interface is supported. The setting interface is intuitive and simple. Offline downloading is not supported, so it's OK to make a central memory or something. In terms of hardware, 256m RAM and 16m ROM.
The WD My Net N900 recently costs $69.99, or about 430 yuan. The price is about 540 yuan, which is almost equal to the price of 1T hard disk+ordinary routers. It still has some price advantages.
