I've been getting unknown devices connecting to the wifi for example: Generic Brand Vendor: HuiZhou Gaoshengda Technology Co.,LTD, Generic Brand Vendor: Gigabyte, and multiple ARRISGro and Quantenn devices. I was wondering if these devices are trustworthy or I should deactivate them. Thanks in advance!
Those things are typically Smart Home / IoT devices, and your own gateway device. What you can do if you like for a test is to block them one by one and see what devices on your home network no longer function.
