Bin for several years O2 DSL customer and a few weeks ago my router was faulty. Information from O2 buy a Fritz Box for 200.00 euros from us, other devices are no longer Supportet. This O2 router does not exist anymore and were also scrap na Hello statements about displaced by O2 technology !!! Another option would be a third device, here then but parameters must be set. For me, all too complicated. I then acquired by privately such a Classic Router, he was unused stored well for some time. Connected and within ten minutes connection worked again. The router configures itself entirely on its own and runs the latest firmware. I hope that part is now running again for a long time, but I'm going to switch from DSL providers. Then there are added new hardware. On the web the way, many complain O2 customers about these routers, most likely you have to be lucky to get a device that runs long.
