I'm using a WRT320N not only with an iPad and MacBook Air per this TomatoUSB thread, but also with the Google Nexus S. The Nexus S is capable of 802.11 N but in the 2.4 GHz band only. Specifically am using on the WRT320N from 30 November 2010:
So I configure as follows:
2.4 GHz, N Only, WPA2 AES, broadcast SSID disabled, MAC filter, 40 MHz channel width, channel Auto
In the Nexus settings for WiFi it states:
XXYYZZ Not in range, secured with WPA/WPA2 PSK
where XXYYZZ is the SSID of the WRT320N.
When I enable broadcast of the SSID, the Nexus S reconnects. Why is this? There seems to be an issue with devices not being able to maintain a persistent connection to the WRT320N with TomatoUSB when the SSID is not broadcast. Wherein lies the problem? It strikes me that this is either WiFi hardware device problem (the WRT320N) or a firmware (TomatoUSB) problem (though it could be a device problem such as Android / Samsung / iOS / Apple) I am kind of doubtful that both Apple and Google would get this wrong. Any thoughts?
