I found that the 111 had properly set itself to AP mode with the settings shown in Figure 6, which included a Channel Width of Auto 20/40 for maximum throughput and WPA2-PSK for maximum security.
Figure 6: Setup Wizards
The admin interface of a 111 in Bridge mode is pretty much the same as an AP's, with appropriate changes to accomodate the difference between an AP and Bridge functions. You have no control over the Bridge mode's channel on the Wireless Settings page and in the Advanced Wireless settings you can't control the Beacon Period and DTIM Interval and there are no enables for 802.11d or Wireless Isolation.
A 111 in Bridge mode also doesn't have MAC Address filtering and there is no DHCP server option when you switch the Network Settings to Static IP mode, as there is for a 111 in AP mode.
There are a few errors in the online documentation (the right hand frame) when the 111 is in AP mode that are worth noting. You can ignore references to WPA Enterprise mode on the Wireless Settings page; it's not supported. And on the Advanced Wireless page, ignore the references to WDS; it's not supported either.
Since the 111 is based on a Ubicom processor, you get their WISH wireless auto QoS, which is controlled on the WISH page (Figure 7). By the way, kudos to Netgear for not renaming Ubicom's WISH (Wireless Intelligent Stream Handling).
Figure 7: WISH
WISH is disabled by default. But if you choose to use it, you should enable it only on the 111 that is in AP mode. To see if WISH is doing anything useful, Ubicom has two online tests that you can play with: one for gaming and one for Voice.
But when I tried out the Voice test, it showed no improvement (Figure 8) on my DSL connection that has around 800 Kbps of uplink bandwidth. (The test configuration was Computer - WNHDE111 - WNHDE111 - Router - Internet.)
Figure 8: Ubicom Voice Test Result
If WISH had been doing its job, the Home Voice Quality scores in Figure 8 would have been more like the Internet Voice Quality scores. But I also ran the tests with a wired connection and a Ubicom StreamEngine enabled router and obtained similar results. So perhaps the Ubicom test site was having a bad day.
Updated 12 March 2008 It turns out that Ubicom's online tests are only helpful for QoS that is applied at a LAN's gateway router and not inside the LAN. So the results that I obtained, which showed no improvement with WISH enabled, were correct.
