 FRITZ!Box 7520 |
Overview[edit]
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).
Note that the information above is merged from all current Firmware versions available for this model, if there are multiples.
For a more detailed per Firmware view see the Firmware-Scans below, and have a look at the Firmware-History.
