Wlan 7170sl

[neca]

I use FRITZ!Box Fon WLAN 7170 SL Annex B for 18 months now without any problems. The only problem is in the user interface which is in German language and which is less familiar to me. Will FRITZ!Box Fon WLAN 7170 SL Annex B work normally if I install firmware 29.04.57 Annex B English language which purpose is for FRITZ!Box Fon WLAN 7170?
