WiFi data rates on Beaglebone Blue

Hi,

I have been using the BeagleBone Blue for a few days now. I’ve noticed that WiFi performance is sub-par when compared to the BeagleBone Black with a USB WiFi dongle. The signal strength has been eliminated as a factor. My speeds over scp have been consistently below 2MB/s. Is this normal? What sort of data rates have you guys been getting over the WiLink1835MOD on BeagleBone Blue?

That's 20Mbit/s, which is perfectly respectable for a 1x1 interface in
a 20MHz channel.

If you've plugged both antennas in, you can switch the chip to 2x2 mode
by creating a file /etc/modprobe.d/wl18xx.conf with the following:

  options wl18xx ht_mode=default

This should roughly double the throughput, but only if both antennas are
plugged in.

Hi Juliusz,

I have both the antennas plugged in and will try it out with the changes you mentioned. I’ll post the results soon.

Thanks and Regards,
