Crippled to 10/100 Speeds !!!
on 23 June 2014
Whereas I am happy to state that this Powerline Adaptor easily distributes network and internet access around my home with a minimum of fuss, I am both shocked and annoyed to find out that the adaptor is crippled by an ethernet adaptor which is only 10/100mbps.
To explain, the DLAN 500 Powerline system creates a network within your electricity supply which is *theoretically capable* of transmitting data at 500mbps, but since the ethernet adaptor is only 10/100mbps, the maximum speed which the device will ever transmit data is only 100mbps. This is a bottleneck which can never be overcome.
The main reason I bought these devices was to backup to a NAS (network) drive. When the NAS is connected directly to my computer (gigabit connection), I easily reached transfer speeds of 36MB/sec. When connecting the NAS via the DLAN500 Powerline, I struggled to get 6MB/sec. That's about 1/6th of the speed.
6MB/sec is fine for downloading from the internet or streaming video to any of your devices around the home, but it is completely inadequate for backing up to a NAS!! A 1TB backup would take more than 2 days at this speed, rather than just 7 hours at the faster speed.
Why did Devolo create a device which was so crippled from the offset?
I now see that there are DLAN 650 devices starting to come out which have true gigabit connections, so these should correct the deficiencies of these DLAN 500 devices. It looks like I will have to spend more £££ to upgrade my network, but I should never have had to do this !!
