1.  Occasionally the R36 will “hang up” and not function.  Remedy: Remove power from the R36 for 15 seconds and then reapply  power.  The R36 will then resume normal operation.
2. IP address conflicts may occur when too many devices start their DHCP assignments at the same place.  You can control this in the R36 by accessing the R36 at 192.168.2.1, then clicking on “Advanced”, then clicking on “LAN”.  DHCP settings are provided in the second section on that page, and begin at 192.168.2.100 and end at 192.168.2.199 by default.  Change the start point from 192.168.2.100 to 192.168.2.133 – it seems to help.
3.  Any 802.11 transmitter may have a stated bandwidth of 20 MHz but this is only the 3 dB or half-power bandwidth. The actual spectrum extends much further than that.  Because of this, WiFI adapters and routers, including the R36, should be physically separated and/or shielded from each other for best results:  If possible, put one device on channel 1 and the other on channel 11 as a starting point.  Then use physical separation and antenna patterns to minimize interference between devices. The interference will show up as a reduced connection speed from what could be done before the R36 was added to the system. Operating the LAN (R36 to user computer) at 11 mbps
4. (802.11b) seems to help also

WPS is a type of WiFi security called WiFi Protected Setup

R36 POWER

The R36 comes with a 12-volt AC/DC adapter with a standard DC barrel connector.

The R36 requires 12 volts DC at up to 1 ampere. The center pin on the R36 power connector is positive, the sleeve is negative. The wire with the white stripe from the R36  power supply is positive. The R36 supplies 5 volts DC to the wifi adapter via the USB cable.
