I picked this router as a cost-effective alternative to an old Speedport router. Use the reviews here I did it establish a connection (T-Online to enter data correctly, VLAN ID change / disable). Unfortunately this connection is anything but stable. At least 3-4 times a day lose contact with the different game servers are identified and blocked despite release and port forwarding as an attacker and the grand finale breaks once a day the WLAN connection together and can only be with the unit is restarted again reactivate , For comparison, I connected an old modem router, which worked perfectly.
Negative I experienced the extremely ugly and slow config surface, which reacts only very sluggishly and endless waits for the smallest configurations displays - if you have since found the desired settings in confusing menus. Other manufacturers can do better.
All in all, no more than 1 star and the unit goes back again.
