** Description changed: + If the mobile data connection drops due to signal loss or modem reset ( + eg. changing radio technology, setting 3g slot, ... ), there's a delay + of 5m before NetworkManager attempts to re-connect. + + The original bug pertained to changing the radio technology ( which + causes the modem to unregister and then re-register using the new + technology ), however the problem is more generic. The steps to + reproduce focus on this case, as this is the easiest way to get the + modem to drop the connection for long enough for the problem to occur. + + Forcing the modem to disconnect via wrapping the device in tin-foil + should also trigger the problem. + Steps to reproduce: 1. Confirm cellular data (disable wifi) 2. Change TechnologyPreference on online SIM 3. Confirm no cellular data 4. Wait ~10 minutes - 5. Confirm cellular data + 5. Confirm cellular data What happens: Changing something on the modem causes cellular data to disappear for 10 minutes What should happen: It should behave as before, i.e. cellular data should come back immediately current build number: 97 device name: krillin channel: ubuntu-touch/devel-proposed alias: ubuntu-touch/vivid-proposed last update: 2015-02-02 12:48:25 version version: 97 version ubuntu: 20150202 version device: 20150128-5379bdb version custom: 20150202
