The internet experienced significant delays on the PC.
It seems your internet connection has been inconsistent lately. About three days ago, speeds were very slow, and now they fluctuate between 40 down and 50 up. Sometimes it drops extremely low or causes lag during gameplay. This issue hasn’t happened before and is becoming increasingly frustrating. It appears to affect only your PC, while other devices work fine. You tried restarting the computer and reseating the Wi-Fi card, but the problem persists. You also attempted reinstalling drivers for the card, wondering if it might be the cause. Your old antennas have been functioning well for years, so you’re considering whether the Wi-Fi card itself could be the issue.
Use WiFi Analyzer to perform a wireless scan. Capture images from the ‘Analyze’ section on both 2.4GHz and 5GHz bands.
Your internet service provider is likely 5GHz or Ethernet, depending on your connection.
Your ISP is AT&T. It seems you're unsure about switching to 5GHz and don't know if you need to log in online or use an app. You might want to check your router settings or contact AT&T support for guidance.
Your ISP gateway device that supports 5GHz wireless broadcasts should offer a distinct SSID for connection. Remove your current 2.4GHz network and join the 5GHz one using a comparable name, such as ATT7Bk18Px_5G. Use the identical Wi-Fi password.
