Hi,

I found a hotspot my Aquaris E5 (Ubuntu 15.04 (r3) - in other words, 
OTA-4?), as well as my Ubuntu 14.04 computer, can't connect to. It's an 
unencrypted g hotspot at a hotel. Everything else connects (OS X on the 
same computer, iPhone, Android phone, PS Vita, you name it).

It's really annoying, especially as I'd been really looking forward to 
playing around with OTA-5 this week on my holiday. :-(

I have until this Sat to debug it, as that's when I'll be leaving. Do 
you guys think we can make Ubuntu better in that time? :-)

It's hard to get info off the phone without internet, so here's _some_ 
of what syslog grepped with NetworkManager spits out:

Activation (wlan0) Stage 1 of 5 (Device Prepare) complete
Activation (wlan0) Stage 2 of 5 (Device Configure) complete.

(wlan0): supplicant interface state: disconnected -> scanning
(wlan0): supplicant interface state: scanning -> associating
(wlan0): supplicant interface state: associating -> completed
(etc)

Desktop Ubuntu does a similar thing: sending out DHCP requests and 
seemingly never receiving a response.

Any ideas how to debug this in more detail?

Thanks,
