[Bug 1349572] Re: Wireless network disconnections on Dell XPS 13
Hi Seth,
I had no disconnections, now for a 3h period (a fabolous improvement!)
Speed seems to decrease, at least with a speedtest:
http://www.speedtest.net/my-result/3668258447
I know, it is not a valid test, but maybe is a reference. I tested it
with various servers and seems a limit at about 5Mbps.
Firmware is 22.24.8.0.
With this versions I don't get an strange phenomenon where "System Load
Indicator" showed equally separated peaks of infinity connection
download speed.
Is there a method to know if there was a disconnection? I mean some kind
of "dmesg | grep xxxx"
Tomorrow I'll try it at other locations.
