[beagleboard] Recommendations for a 5GHz WiFi solution?

Yea I know this isn't really a beaglebone question but thought I would ask here first since we use beaglebone for prototyping. My boss wanted me to conduct some 5GHz WiFi testing so my usually tp-link and TI wilink solutions are no good as they are 2.4GHz adapters only. Anyone recommend any

Re: [beagleboard] Recommendations for a 5GHz WiFi solution?

As you noted it is hard to tell which ones use chipsets that support 5GHz so I order two D-Link DWA-160 and two TP-LINK TL-WN821N. 10-20$ each... I'll post back here when I get them and run some 5GHz tests... -- For more options, visit http://beagleboard.org/discuss --- You received this

Forgot to attach the file! Also note in order to get multichannel audio working with the 3.8 kernel you need to apply these patches that are not in the 3.8 kernel: http://lkml.iu.edu//hypermail/linux/kernel/1302.3/02415.html I believe the newer kernel (3.13?) contains these patches but it broke

Re: [beagleboard] Changing BB-BONE-AUDI-02-00A0 from McASP AXR2 to AXR3

Yep and just to verify I tried it: I tried setting it as 0x02 and it still works! So I get the exact same behavior whether it is: pinctrl-single,pins = 0x198 0x20 /* mcasp0_axr0, INPUT | MODE0 */ 0x1a8 0x20 /* mcasp0_axr1, INPUT | MODE0 */

Does cape support (audio cape specifically) work with newer kernels? Going from 3.8.13 - 3.13. I wanted to grab some /kernel/sound/socdavinci-mcasp.c changes that took place last year. Specifically davinci-mcasp: Add support for multichannel playback. It looks like the current 3.8.13 kernel
