Title: Wifi intermittently stops working since 15.04 upgrade Status in wpa package in Ubuntu: Incomplete Bug description: Since upgrading to 15.04 a couple of weeks ago I have been finding that sometimes my wifi completely stops working. Restarting network manager doesn't help, nor does removing and reinserting the wireless driver. I can get network access through an ethernet cable. Another, possibly related problem I have been experiencing since upgrading to 15.04 is that sometimes wpa_supplicant starts hogging CPU, up to 100% on one core. When I kill it, the replacement instance of wpa_supplicant continues to hog the CPU. I am not sure whether this is caused by the same fault that is causing my wifi to fail. As I send this error report, my machine is in such a crippled state with no wifi and wpa_supplicant slowing everything to a crawl. I noticed that wpa_supplicant was misbehaving only after I had tried removing and reinserting the wifi driver, so I don't know whether the wifi failure problem caused wpa_supplicant to go bananas, or whether it was the fact that I had messed about with the driver.
