Here is all there is to setting the Bullet up from scratch fresh out of the box and all anyone can do for you in advance.
1) On your laptop
go to Start>Settings>Control Panel> Network Connections
2) Right Click your wired adapter and select properties then Internet
Protocol and click Properties.
3) Select "Use the Following Address" and set the address to 192.168.1.1, mask 255.255.255.0 and Gateway ti 192.168.1.20
4) Select "Use the Following DNS Server and set it to 192.168.1.20
5) Click OK back to the desktop
the Bullet into your ethernet jack and start your browser.
6), Navigate to 192.168.1.20 and log in to the Bullet.
7) On the Network tab set the Network Mode to Router, WLAN IP Address to DHCP.
8) On the lower half of the screen
set the LAN IP Address to 192.168.20.20, Mask to 255.255.255.0, Enable NAT, Enable, DHCP, set a start and end range of addresses you want the Bullet to assign and click "Change".
9) On the LINK tab, set the Wireless Mode to Station, set the power to 36 minus your antenna's gain and click "Change" then "Apply".
10) Close your browser and repeat steps 1 and 2 to reset the address and DNS Server to Automatic.
Now any time you pull into an anchorage and want wifi
browse to 192.168.20.20 and log on. On the LINK tab click the SELECT button and the Bullet shows you all the signals in the area. Pick the one you want and click "Change" then "Apply".
There are many more things you can do with AirOS that you probably will never need but when someone "simplifies" it and presets everything you are for ever locked out of optimizing your individual configuration.
Now, as to the 8dBi antenna. The Bullet 2HP can output a maximum of 29dBm. Add the 8dBi antenna and you are 1DB over the US limit. BUT on the LINK tab there is a little slider you can use to set the maximum power. Drop it just a notch and you are nice and legal
but if you are anchored out in some lonely bay and the only signal is just a little to weak it is nice to have a dB or two in reserve.
