Slightly odd one this - we had a series of issues with a client who was using a number of Dell XPS laptops, with Windows 11 and USB3 <=> Ethernet adapters based on the Realtek chipset, where the large downloads kept failing. Worked fine over Wi-Fi and with USB adapters which did not use the Realtek chipset.
To test this out seriously we needed a script which attempted to download a large file and write the result to a log file. This is it.
# Script to run in Powershell to download test files of various sizes
# DKM 2023-04
# DKM 2023-07 added logging function
#
#
# Source files from http://xcal1.vodafone.co.uk/ - see which for alternatives

#
# Function to write log
$Logfile = "C:TempDownLoadTest_$env:computername.log"
function WriteLog
{
Param ([string]$LogString)
$Stamp = (Get-Date).toString("yyyy/MM/dd HH:mm:ss")
$LogMessage = "$Stamp $LogString"
Add-content $LogFile -value $LogMessage
}
# End of function to write log
# Run Dowload
$GetInfo = {
Invoke-WebRequest -OutFile testfile.zip -Uri http://212.183.159.230/100MB.zip
#
# Write result to log
WriteLog "Downloaded…."
#
# Wait and then loop
Start-Sleep -Seconds 10
# "Files are successfully downloaded in $env:computername" | Out-File -FilePath C:TempFileDownLoadLog.txt –Append
#
.$GetInfo
}
&$GetInfo
and this is a typical log:
