[Bug 1418077] Re: After connection drops, mobile-data takes ~5m to re-connect
** 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
