mine? I have 2 V1G0R5G and V1G0R2G. and I use wpa2/psk security

Okay, not that then. Someone suggested that 'spaces' in SSID names can confuse iOS!

Nope - exactly the same, so I've now wasted the cost of postage now! Just been sent a further beta version of the firmware (3.7.4.2_RC1b) but that still exhibits the problem.

I'm starting to loose patience with this now.

I see a problem where the WiFi itself is stable (this is 2.4GHz n), but traffic gets lost for about 20sec every 3-5 minutes.
I'm testing this by running a continuous ping to the 2760n+, which shows that there is no reply for 20secs every 3-5 minutes, while the connection remains stable and up.
We have various other APs on the premises, none of which exhibit the same problem.
I've gone through all (!) possible settings and combinations thereof, and there is absolutely no difference in behaviour.
Btw: I didn't see this on 3.7.4.0, but I do see it on 3.7.4.1 I hear release 3.7.4.2 rc 5 will be available tomorrow from support if you email them.

Switching channels and angling aerials makes absolutely no difference - what a nonsensical suggestion.

tobythetenor - this is exactly the issue I'm seeing. You only notice it when streaming etc, or at least something that requires constant downloading while monitoring. Apple TV for example, or a PS4.
