Problem is that 2.4Ghz is very polluted ie plenty of devices.
And with 40Mhz you are asking to double the bandwidth, which you usually do not have available in the 2.4GHhz area.

2.4Ghz got 3 none overlapping channels and you are basically asking to use 2 of those 3.

5Ghz got lots more channels, I do not remember the exact number, but there 40Mhz works better.

EDIT : 23 Channels in 5Ghz

Sorry but I',m not clear on this at all !]]> http://www.dslreports.com/forum/Re-ZyXEL-NBG416N-firmware-v500-v600-unstable-on-PPPoE-fix-27980295 Tue, 05 Feb 2013 07:14:47 EDT http://www.dslreports.com/forum/Re-ZyXEL-NBG416N-firmware-v500-v600-unstable-on-PPPoE-fix-27980235 Only exception is if your alone in the 2.4GHz band :)

These new firmwares proved to be highly unstable so I reverted to v5.00 (rock solid with 40Mhz WLAN off).

After upgrading to v6.00 / v7.00, you can't downgrade without doing a special firmware flash procedure.

Details are here: »Zyxel NBG-416N firmware recovery

My tips for this flashing procedure:

To use tftp cmd line in win 7, I had to install it from the Windows features in control panel.

I then let it through windows firewall.

Stupidly; I tried several times without result before realising I was pushing on the wireless pin button and not reset !

Now back to V5.00 and all is good.

The needed recovery files are in the link given. Once you downgrade it's possible to upgrade back to v4 or 5 . ]]> http://www.dslreports.com/forum/ZyXEL-NBG416N-firmware-v500-v600-unstable-on-PPPoE-fix-27980121 Tue, 05 Feb 2013 01:54:23 EDT
