I have the same router on our local set-up. It's not in regular operation yet,as we're waiting for the internet connection, but I looked at the firmware and it's 3.something !
As soon as I can, I'll do the test, - we have no security turned on at the moment (no need as it's hardly ever switched on except for testing, and we're a pretty remote area anyway. I suppose if somebody really WANTs to park on top of the wadi and point a cantenna at me . . .
).
Just makes me wonder how long it's been sitting in the shop's stock with firmware that old, and we only bought it a couple of months ago!
I'll let you know when I check the security on the old firmware (probably works, and it was the mods that brought it up to 4.whatever to fix other problems that caused the security hole!)
