I purchased my Nokia 8 at the end of last year (December 2017), it has been working perfectly until a few weeks ago. I recently had to replace my modem and router and hence changed the network details. For some reason ever since the change my phone will randomly freeze for a few seconds before restarting. It does this often at home when I'm using it or even when it's just charging. I have tried factory resetting but to no avail. It's an extremely weird issue as it has only occured when connected to this network. Any reason as to why this might happen, or is purely a coincidence. The only different in WiFi networks (old and new home setups) is that there is now a space in the wifi network name as well as two question marks at the end of it. Other than that it's a perfectly fine network with all my other devices working perfectly. I'd appreciate the help or whether anyone else has experienced different issues.
Thanks in advance
