IP block is an event generated by you or any other user simply trying to log in to the router. It monitors failed login attempts to block unauthorized access in case a number of login attempts is exceeded.
Switch events indicate state, speed, duplex mode negotiations between connected devices, used ports.
None of these should influence mobile connectivity.
I would like you to attach a troubleshoot file to your question. Please, replicate the issue, then access router's WebUI, go to System -> Administration > Troubleshoot section and download troubleshoot file from there.
