I haven't been updating the firmware of the WNDR3700v1 that I use as my main router. So these observations are based on changes seen between version V220.127.116.11NA firmware on the v1 and V18.104.22.168 firmware on the v2.
The first thing I noticed was the removal of support for WEP security for the main SSIDs when I went to check fallback to 54 Mbps link rates when it was used. Figure 7 shows the central frame of the Wireless Settings page.
Figure 7: WNDR3700v2 no WEP
Curiously, WEP does appear as an option in the Guest network settings, along with a new Wireless Isolation option, as shown in Figure 8. The online help hasn't been updated to describe the latter. But Wireless Isolation usually prevents wireless clients from accessing or seeing each other.

What hasn't changed much is the ReadyShare USB drive sharing features or performance. The only feature difference I could see is the removal of the scheduled scan setting for the DLNA sever, leaving only the Automatic scan option.
To test performance, I once again connected the Iomega UltraMax Pro dual-drive RAID 0 configured NAS that I use for NAS backup testing and ran the filecopy test from the NAS test suite. With the Iomega drive NTFS formatted, I measured only 3 MB/s writing and 12 MB/s reading. When I reformatted the Iomega as FAT32 and reran the filecopy, performance improved to 12 MB/s writing and 14MB/s reading.
Other changes I found include:
- Filters for the Logs
- Addition of Guest Network information to the Router Status page
- Addition of wireless devices to the Attached Devices page
- Renaming of Disable SPI Firewall to Disable Port Scan and DoS Protection on the WAN Setup page
- Addition of a Automatic uplink bandwidth check option to the QoS Setup page
- Addition of IPv6 support
That last bullet is perhaps the most significant, even if most US ISPs don't yet use IPv6 on their networks. The v2 supports 6 to 4 tunnel, Pass Through, Fixed, DHCP, PPPoE or auto detect WAN types. Figure 9 shows the Fixed type entry screen.
