Secret setting makes your Fritzbox even faster!

AVM’s Fritzbox are very popular with consumers. They offer high speeds and stable connections. But did you know that there is still a well-hidden “Power Mode” in the settings that provides a further speed boost?

The Fritzbox is so popular with many users because it offers a menu with many customization options. This allows the router to be set up individually. Many functions are easy to see and self-explanatory. However, there are also settings that AVM has hidden well, but they are definitely worthwhile.

AVM delivers most Fritzboxes in the frugal “Green Mode” ex-factory, which throttles the speed of the Gigabit LAN and USB ports. This is especially often the case with models that you get from your Internet provider. However, the LAN and USB ports can also be operated in the so-called “Power Mode”. This means that the data rate of the Gigabit LAN port increases from 100 megabits per second (Mbit/s) to up to 1000 (i.e. 1 gigabit per second) – a noticeable speed boost. You can also unlock more speed in the built-in USB ports.

How do I activate the Power Mode?

To activate the Power Mode, you first have to go to the menu of the Fritzbox with your computer. To do this, simply enter in the browser and log in with your login data.

From the “Home Network” menu, click on “Network” and then on the “Network Settings” tab at the top. There you will see a list of the various LAN ports under “LAN settings” – and you can switch between “Green Mode” and “Power Mode” there. However, the mode does not affect the WLAN, but only devices that are connected with a LAN cable and the router.

Under “Home Network” and “USB Devices” you can thus also adjust your USB ports. By default, the USB ports only operate at USB 2.0 speed to save power. The “Power Mode” switches to UBS 3.0 and thus increases the transfer rate significantly. Especially for external hard drives with the blue USB 3.0 cable, this setting is a must.

Which Fritzboxes support Gigabit LAN?

Almost all of them. Few exceptions are, for example, the Fritzbox 7430 or the Fritzbox 4020. On the official homepage of AVM, you can find an overview of all current devices – including whether there are ports for Gigabit LAN or not.

When does Gigabit LAN make sense?

The option primarily makes sense for people who transfer large amounts of data – such as for elaborate Full HD or 4K video streams. Those who use many devices in parallel in their network also benefit from the speed boost. However, the end device must also have a Gigabit LAN port. This is the case with many newer desktop PCs and laptops.

Users who do not have a Gigabit LAN-capable device and only surf the net with their laptop from time to time, check a few e-mails or watch a YouTube video should stay with the more frugal “Green Mode” – an effect would hardly be noticed here.

If you want to know how much speed you actually need for which purpose – this article clarifies.

atechbook says

Those who have a gaming PC with Gigabit Ethernet and a fast Internet connection should definitely turn on Power Mode and connect the PC to the Fritzbox via cable. Those who use a NAS server at home will also benefit from the higher transfer rates when they move data over the network. Otherwise, we simply recommend testing whether Power Mode makes a difference in Internet speed. If not, you can always simply re-enable Green Mode.
