all my large downloads are corrupt when using fdm on Wi-Fi. I have upgraded the router no luck. reinstalled fdm. If I download regular in chrome the file is fine.

Hello,
Any details? OS version? FDM version? Any examples of such downloads (URLs)?

problem fixed, not sure what the exactly the issue was. I Change the router, change my virus scanner from Kaspersky and also change the setting in my network adapters to not allow Wi-Fi to go to sleep
