Unable to access certain websites, sometimes

[SkyBillPayer404]

Good evening. For a few days I have had difficulty accessing some URLs, at some times, including being unable to reach the router via IP address. One of the connected devices is currently experiencing sever problems, and has been for the last few days. I have rebooted the router both through the IP address, and physically with the router, but the problem persists. I have also tried diagnosing IP address issues through Windows Command Prompt, to no avail. Please advise, thank you.

Good evening, 

I'm adding to this as it still has not been resolved, and has now worsened on one of the connected devices. 

I have tried altering DNS settings on that device to both Google and Cloud flare, and even utilised CMD.exe command prompts, to no avail. 

Moreover, I cannot connect to the router via the affected device through ip address directly, but can by connecting my phone, turning on its hot-spot, and then going to 192.168.0.1

• Can anybody please help, or point me in the right direction, as this has been going on for about a week, now.
