FRITZ!Box 7520

The FRITZ!Box 7520 was silently introduced by 1&1 at 2019-02-02^[1], as one of their lease purchase routers, in 1&1 typical black casing. This model shares the same features as the 7530, just only 2 of the 4 LAN-Ports are GBit, the USB-Host is only v2.0, and the VDSL frontend chip seems to be different (subject to research).

Characteristics[edit]

The 7520 is similar to the 7530 but 2 of the LAN ports are limited to 100 MBit/s while the hardware supports 1GBit/s.
The full speed of the limited ports can be reactivated per software tweak.^[3]
