I recently added an Archer T4E adapter to my setup and have experienced ping fluctuations reaching up to 3000 ms. These spikes happen when connecting from this PC to the internet (such as testing google.com) and also when communicating with the router I’m directly linked to via Wi-Fi (my TP-Link AC1900). The spikes aren’t seen on any other device on the network, whether wired or wireless. They seem to appear only after the computer powers down and then comes back online. A restart resolves the issue temporarily, but it’s not a lasting solution. I captured a screenshot of the ping command showing irregular gaps between spikes—sometimes over 20 seconds apart, other times every few pings. I’ve installed the latest driver, tried reverting to an older version, and even updated Windows Update settings, but the problem remains. The driver I downloaded from TP-Link is the newest available, though it was released in 2018. Changing power management options for the card didn’t help either. Using a wired connection eliminates the issue, confirming it’s a local Wi-Fi problem rather than a network-wide one. Sometimes restarting the WLAN Autoconfig service helps, but only intermittently. The most dependable fix is rebooting the PC itself. Any advice would be appreciated, as I’ve looked for solutions without success.
