I've had a Lenovo G51 with realtek 8821ae wireless lan 802.11ac pci-e nic
My wireless is always painfully slow until I open the Device Manager and then Disable and then Enable the network adapter. Then my internet runs fast for around 30min-1hr, although sometimes less, until I have to cycle through the Disable and Enable. (I have confirmed the issue is from my computer as I have this issue no matter what network I'm on, and no other devices have similar issues on my current home network).
I've tried several things to fix this:
Taken off power save modes
Turned off virus scans
Checked for corrupted files
Updated driver software
Nothing works. I've got a feeling it's just that Lenovo put in bad hardware and there's nothing I can do, but maybe someone has a fix I'm missing? Thanks in advance

Thanks for using the Lenovo forums.
Try to download the Chipset drivers for the unit from the support page.
Make sure to reboot.
Try to run an LSC scan, and see if that can find any errors for you.
1. Please click on the following link
2. Under the section ‘Download’ select the relevant Hyperlink dependant on whether your Lenovo is running Windows 7/8/8.1/10 32 bit or 64 bit.
3. When prompted, select save and browse to a drive and directory in which to save the downloaded files.
4. Navigate to the folder where you saved the installation file, lscsetup_x86_26001.exe.
5. Double-click the installation file icon to start the installation.
6. Follow the onscreen instructions via the installation wizard that will install Lenovo Solution Centre on your system.
7. Once installed you will have a ‘Lenovo Solution Centre’ icon on your desktop please click to open this.
8. Once solution center is opened please select ‘Checkup’ then ‘Hardware Scan’ and ‘Full Scan’
9. This will take up to 20 minutes, see if this can find any errors.
Hope this helps, let us know how you get on.

Thank you for your reply!
I attempted to download and install the Chipset from the following link:
It statated that it could not complete the install because I do not have the requisite hardware requirements. I have a Lenovo G51, Windows 10 64bit....so not sure what the issue is here.
I already have Lenovo solutions center, and scans have not found any issues.
The problem is still persistent.
