+# Unstable connection
+We get some bug report about unstable connections and different weird issues. Before reporting a bug, please check:
+* is it working with other (shorter?) cable? This HW seems to be picky about cable quality, so check it.
+* is it working with powered USB hub? People had issues with some specific usb controllers. Test on other HW if possible, or at least find some cheap powered usb hub.
+* is it working with LED disabled? LEDs are triggered from host over USB. Looks like some host controllers don't like it. Use this command "sudo bash -c "echo none > /sys/class/leds/ath9k_htc-phy*/trigger""
