~ 180Mbit (approx 22MB / s) at the same stage in the same room
~ 120Mbit (approximately 15MB / s) in the rest of the apartment
~ 90Mbit from the roof to the basement of an apartment building (after all 5 floors)
However, the supplied software displays absolute fantasy values regarding the connection quality. So were each given for upstream and downstream, at best, about 450mbit, but the real data rate was more than half lower. The tool is allso simply useless for speed measurement (not even the transmission overhead can explain this discrepancy).
The real problem of the adapter lies in the new feature the latest firmware. Here is an energy-saving mode has been integrated, which enables the devices to save energy when not in use. What Netgear has this but not thought - and what has also been repeatedly criticized in forums - is that even in standby befindlicher adapter no longer on the current page (ie from another powerline adpater) is awaken. Only one LAN activity or a disconnection from the power on "dormant" adapter can also reawaken this.
So you installed the adapter in inaccessible places one has a lot of fun when it is in standby. In my case, I would, at worst, in the cellar go un disconnect the Powerline adapter from the mains. You can see the power saving function by the way, of course, do not switch off - why ?! Well done Netgear!
The support confirmed to me this inability of the adapter, but could offer me no solution. You could / wanted to perspective not comment. The mere disclosure of the problem to another location would be done. Conclusion: The support has only cost me unnecessary time and precisely nothing brought. From a willingness to remedy a problem that the manufacturer has to answer for himself, there was no trace. This product is at present not well thought out and immature. There remains only the return and the purchase of a competing product. So not Netgear!
