Just got a new netgear 802.11n wireless access point, works fine on the laptops in full 802.11ng mode but the iphones (4S's) wont connect unless I drop it to 802.11bg mode.

Anyone else come across this issue?

As far as I was aware the phones would connect at g in 802.11ng mode if they didn't support n (which I believe they do).

i phones dont work to well on N due to interference.
