My problem that I haven't been able to figure out for almost a month is that my dhcp lease time expiring every hour. It obtains the lease when i turn my computer on and expires exactly every hour after it was obtained. My problem is that after that hour it kicks me offline for like 10 seconds then comes back on but it disconnects me from everything im doing. I also think that it is only affecting me when im on my pc not on my phone or anything and my isp said everything is fine on their end. I dont know what the cause of this could be maybe someone can help because this is super frustrating and i use my isp modem and router. if you need more info let me know ill try and provide what you need.
