I have a one-year-old Lenovo Yoga 7 2-in-1 running Windows 11 Home. Over the past few months, websites have taken unusually long to load, and file downloads and uploads are much slower than expected. Other devices on the same Wi‑Fi networks work normally, and the problem also happens on several different networks. I've already tried resetting the network, changing the DNS servers, and uninstalling and reinstalling the network adapter. Those steps helped a little, but the laptop is still much slower than it should be. A recent speed test showed about 20 Mbps download and 30 Mbps upload, with a best result of around 60 Mbps. The laptop is slightly warm but not overheating, has plenty of free storage, and does not have third-party antivirus installed. What else should I check?

Storage space probably isn’t the cause here. Having 382 GB free and seeing a blue drive bar means the disk is not close to full. If the problem continues after checking background processes and drivers, run Lenovo’s hardware diagnostics and test the Wi‑Fi adapter in another way, such as with a USB Wi‑Fi adapter or Ethernet. That can help determine whether the built-in wireless adapter or its antenna is failing.
First, check whether anything is consuming network or system resources. Open Task Manager with Ctrl+Shift+Esc and look at the Performance and Processes tabs while running a speed test. Also check the CPU uptime. Windows Fast Startup can leave the system running for a long time instead of performing a full shutdown, so try restarting rather than just shutting down, or disable Fast Startup to see whether that helps.
The speed-test results suggest the issue may be specific to the laptop rather than the internet connection, especially since it happens across multiple networks. Check Task Manager during the test for heavy CPU, memory, disk, or network usage, and look for background programs or Windows updates using bandwidth. It’s also worth installing the latest Wi‑Fi and chipset drivers directly from Lenovo’s support page instead of relying only on Windows Update.
The uptime showed 21 hours. I wasn’t sure whether that was unusually high, so I’ll try a full restart and check whether Fast Startup is enabled.
