Got this to extend a BT Home Hub 3 in our Church presbytery - 300 year-old building with 18" thick internal stone walls. Set-up is a doddle via WPS & it works sufficiently well for us to connected downstairs diagonally opposite the router in the office upstairs.
I've got a Nissin Di466 flashgun on my Nikon D90 & these wireless flash triggers won't work with it. They work fine as a wireless shutter release but not as flash triggers. I've tried everything I know & can't get them to work & I'm waiting for both Nissin & Yongnuo to confirm they're not compatible.
