Okay good to know, thanks.

I'm going to google how to do that.

Funny you should say that. The one computer I wanted to connect using
the bridge is running Windows 7 Home Premium. It's strictly for Steam
games that just won't run well under emulation and so on. Anyhow, like
all Windows machines I've ever used, it is an absolute nightmare as
far as networking. Even when it was connected directly to the primary
network by an ethernet cable it would not let me access any SMB shares
or access my Chromecast. It still won't. Of course every other device
or computer, running Mac, Linux, Android or iOS will see and access
the shares just fine, over wireless or ethernet.

I actually tried using WDS to no avail. Now that I know the security
mode may have been the hindrance I might give that a try again. Maybe
Windows will like that better. I'm not holding my breath.

Ya I kinda like it the way it is. The less Windows can access my
network the less harm it can do. It is good for modding and playing
Fallout, that's it :-)

I'm curious tho, how would I bridge wireless to ethernet without a
second router? Wouldn't I need some sort of separate device?
