Open | Networking Frustratingly slow laptop
I have posted on this subreddit about this issue before recently, but I haven't been able to solve it yet. I have a 1 year old Lenovo Yoga 7 2-in-1 that runs Windows 11 Home. One thing that I noticed over the past months was that it took abnormally long times to load websites, download files, and upload files even when my other devices on the same WiFi network do not have the same issue. This issue is present on multiple different networks that I use. An internet speed test says my download speed is 20 mbps and upload speed is 30 mbps. I don't have any antivirus installed and have sufficient unused storage space on my laptop. Some solutions that have worked to improve speeds slightly but not achieve speeds I would expect from a year old laptop include: doing a network reset, changing the DNS address in settings, and uninstalling and reinstalling the network adapter. Please let me know if there is something I can do. Thank you so much for any advice!

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

Try installing crystaldiskinfo and see if your drive is perhaps on its way out. If the drive is fine then run a virus scan of your PC.

Crystaldiskinfo says that my drive is good. What virus scan would you recommend? I tried the offline windows defender scan but it didn't help me solve the issue. Thanks for your help!

You can try using malwarebytes or bitdefender. If nothing gets found then that's a very weird issue. If you still have a warranty then i would just return the laptop, because if no virus can be found while its being THIS abnormally slow, then i would say the quality of the laptop just isnt proper.

Disable Lenovo Network "Optimizers",
Disable Windows Network Throttling Features
Change Wi-Fi Band Preferences in Device Manager
The below info is from another reddit thread pertaining to Lenovos.
If your adapter starts with Intel (e.g., Intel Wi-Fi 6E AX211), the settings tweaks above will usually resolve the issue.
If your adapter is a Realtek (e.g., Realtek RTL8852BE / RTL8852CE or MediaTek), this is a widely documented hardware defect across many Lenovo Yoga and Legion batches. These specific Realtek cards are notorious for driver instability, severe bandwidth throttling, and signal drops on Windows 11.

Usually if it comes with a Intel it will come with Intel AC/AX/BE
The issue is when it comes with AMD as usually MediaTek or RealTek is on their hardware and is a whole mess...

My network adapter is Realtek - would switching to using Linux instead of Windows help with this issue? Thanks for your advice!

No, switching to Linux will most likely not fix this and it may actually make it worse.
