Cannot see 802.11G-only or 5GHz networks #3

I have a Linksys E-3000 running Toastman Tomato-USB firmware (http://toastmanfirmware.yolasite.com/) had it set on the 2.4GHz radio for 802.11G only. (Both B and N were disabled in that band.) My laptop was unable to see the network and attempts to join it as a hidden network also failed. I've had to either enable B and G or use the firmware's "N only" option. While the firmware says "N only" iwlist claims 802.11bgn. I'm not sure if the firmware's UI option is misleading or if there's a bug in how the driver is interpreting the capabilities of the network.

Additionally, the chip cannot see the 5GHz network I have enabled.

The 8723 chip has no 5 GHz radio. It is single-band only. AFAIK, the only dual-band chip that Realtek produces is the RTL8192DE for PCI, or the RTL8192DU for USB.

Is there any output in /var/log/messages that would shed any light on the problem of connecting to an 802.11G network?

I just pushed patches that implement dynamic changed in the debug level. Could you please do a 'git pull' and rebuild the driver and test?

Loading with a simple insmod should produce minimal log output. Using 'insmod ... debug=8' should flood the logs.

Thanks,

Larry

Good to know that the 8723 is 2.4ghz-only... I had been wondering about this since iw list shows the PHY as being 5ghz-capable, although the hard-coded rtw_wireless_mode = WIRELESS_11BG_24N; in os_dep/os_intfs.c clued me in that 5ghz isn't supported.
