The R6250 supports NETGEAR's ReadySHARE drive and printer sharing feature, which the WNDR3800 review covers pretty well. The short story is that ReadySHARE supports file sharing via SMB, HTTP, HTTPs and FTP. HTTPS and FTP are also available via an Internet connection. As noted earlier, access from the internet is not via ReadyNAS Cloud.

I ran Windows filecopy tests using the standard NAS testbed to the R6250 with our USB standard drive (Startech USB 3.0 eSATA to SATA Hard Drive Docking Station (SATDOCKU3SEF) containing a WD Velociraptor WD3000HLFS 300 GB drive) formatted in FAT32 and NTFS. Table 3 shows the results along with some from other draft 11ac routers with USB 3.0 ports (to be fair).
|R6250||D-Link DIR-868L||Linksys EA6300|
|FAT32 Write (MBytes/s)||15.9||16||11.2|
|FAT32 Read (MBytes/s)||25.6||27||17.4|
|NTFS Write (MBytes/s)||17.6||11.5||9.8|
|NTFS Read (MBytes/s)||25.7||13.8||17.2|
Table 3: File copy throughput
NETGEAR looks like it has paid some attention to file sharing performance, with 26 MB/s reads and 16 - 17 MB/s writes for both FAT32 and NTFS formatted drives. This leads the pack of USB 3.0-enabled draft 11ac routers.
Routing throughput was measured running V126.96.36.199_1.0.70 firmware, using our standard router test process. Table 4 summarizes the results, which are lower than the other AC1600 router currently in the charts, the Linksys EA6300v1 / EA6400, for the unidirectional tests. The simultaneous up/downlink test, ranks the R6250 higher than the Linksys, however. The maximum simultaneous connections result of 29,723 was lower than the EA6300's 31,901. But in each case, the router test ran out of Windows ports, so you're seeing a test method limitation.
|WAN - LAN||745 Mbps|
|LAN - WAN||867 Mbps|
|Total Simultaneous||954 Mbps|
|Maximum Simultaneous Connections||29,723|
Table 4: Routing throughput
The IxChariot composite plot below shows relatively steady throughput in the unidirectional tests with LAN > WAN test variation a bit higher than WAN > LAN. The simultaneous up/downlink test shows a familiar pattern, i.e. equal bandwidth sharing toward the start of the run, then a battle for bandwidth causing higher variation toward the end.

Updated 11/6/2013: Wi-Fi Certified Sept. 2013
is not Wi-Fi Certified. It defaulted Auto channel and "Up to 145 Mbps" mode (20 MHz B/W mode) on the 2.4 GHz radio and channel 153 and "Up to 1300 Mbps" (auto 20/40/80 MHz B/W mode) for the 5 GHz radio upon power-up. The router comes with different 2.4 and 5 GHz SSIDs set, so you'll be able to connect to your desired band without having to change router settings.
I ran 40 MHz Coexistence and Fat channel intolerant tests passed to make sure the R6250 behaved when encountering interfering 2.4 GHz networks. The R6250 immediately fell back to 20 MHz mode link rates when the Fat Channel Intolerant bit was set on the client. But when the Fat Channel Intolerant bit was set back to disable, the router stayed at 20 MHz mode link rates for the few minutes that I monitored it. The coexistence test failed, however. With another router set to Channel 11, the R6250 stayed at at 300 Mbps link rate when I set it to channel 8 and even when I set it to channel 9. I made sure the Enable 20/40Hz (sic) Coexistence box was checked (its default setting) for this test.
I successfully ran a pushbutton Wi-Fi Protected Setup (WPS) session with a Win 7 client. The WPS session took about 10 seconds to get started, but then completed quickly and resulted in a WPA2/AES secured connection with the same WPA2 pre-shared key set for both radios.
All tests were run using our new wireless test process and V188.8.131.52_1.0.70 version firmware loaded. The router was first reset to factory defaults and Channel 6 was set for 2.4 GHz and Channel 153 for 5 GHz. "Up to 145 Mbps" (20 MHz B/W) mode was set for 2.4 GHz and "Up to 1300 Mbps" (80 MHz B/W) mode (to enable draft 802.11ac link rates) was set for 5 GHz. The test client was connected using WPA2/AES encryption.
The router was positioned 8" from the chamber antennas in all test positions. The 0° position had the router front facing the chamber antennas.
The retest Benchmark Summary below from the new Consolidated benchmark process shows the average of throughput measurements made in all test locations. The 2.4 GHz values in the summary correspond to 2.4 GHz values (20 MHz B/W) and the 5 GHz values correspond to the 80 MHz B/W - 3 stream values measured with the previous test methodology.
NETGEAR R6250 Benchmark Summary
Comparing average 2.4 GHz benchmark values with the only other AC1600 router we currently have in the Charts, the Linksys EA6300v1 / EA6400, reveals that the Linksys does slightly better running downlink, but vice-versa for uplink. The R6250 does a bit better than the Linksys for the 2.4 GHz UpDown Throughput benchmark with 110 Mbps vs. 104 Mbps.
For 5 GHz, the R6250 turns in significantly better results in the unidirectional tests. But it comes in slightly behind the Linksys with 597 Mbps vs. 605 Mbps.
