Previously, my connection was stable. Now internet drops on all devices, both wired and wireless. Browsers and network settings show the DHCP server unreachable. I’m using an Arris SB8200 modem and a TP-Link Archer C7 v4.0 router, with my desktop hardwired to it. I’ve tried several fixes—restarting router, connecting directly, switching router, changing modem—but nothing resolves the issue. A new modem worked for a week before failing again. ISP and technician checks found no problems during their visit; cables and grounding were fine. The problem seems to reappear after brief downtime. What should I do next? What might be causing this?
The output of the `ipconfig /all` command shows the network configuration, including IP addresses, subnet masks, and gateway settings. During normal operation it displays active connections and DHCP lease details. During outages, it may show errors or missing entries indicating connectivity issues.
It often occurs very quickly, leaving little time to investigate. I'm certain I've previously managed to reach the router or modem's web interface, but now it seems unavailable.
It occurred once more, and I successfully executed 'ipconfig /all' before and after the disruption. The results remained the same.
