X4S File copied over the network fail MD5 checksum and are corrupted
I have the X4S configured as an access point. I have a PC connected to the X4S via ethernet cable. Files copied over the network consistently fail MD5 checksum. I've searched and found a related pos...
by the way for a test you just need to disconnect you cable from internet port and to attach it to the internet port. two seconds. and i beat you will not have such md5sum problems anymore.
The manual states to connect the X4S Internet port to the LAN port of the other router which is how it is/was configured. I take it the "Internet" port is what you reference by "WAN" port. Is there reference that your method should work?

Maybe the error is in the manual. Would it be reasonable to use the second configuration and run a test?

"copied" how, exactly? From what to what (computer systems, storage
devices, ...)? Have the source and destination files the same size?
Are the file data simply passing through the router, or do you have a
USB storage device connected to the router, or what?
Even for Netgear, corrupting data on the fly seems like the kind of
bug which might be caught in even minimal testing.

Not really.

Or, maybe not. On modern Netgear routers with a one-step "AP Mode"
option, the WAN/Internet port is reconfigured as essentially another LAN
port. On a router without a one-step WAP option, the WAN port is on the
wrong side of the LAN-WAN boundary, and is not used.
There should be no harm in trying another LAN port instead of the
WAN/Internet port. I wouldn't expect much to change, but that's what
experiments are for.

devices, ...)? Have the source and destination files the same size?Copied file with Windows Explorer, TeraCopy and RoboCopy. The file sizes are the same when properties are checked using Windows 10 properties dialogue. Copies from one computer SSD over the network to another computer's SSD, HDD or USB HDD resulted in corruption. Files failed TeraCopy and QuickHash MD5 checksum verification
Are the file data simply passing through the router, or do you have a
USB storage device connected to the router, or what?No USB attached devices, just router configured as AP
Even for Netgear, corrupting data on the fly seems like the kind of
bug which might be caught in even minimal testing.Corruption became evident on video and audio files as video had intermittent tearing, pixelation or freezing. Audio file would occasionally have drop outs, clicks or pops. It took awhile to rule out all other possibilities leading to the router. i.e. RAM, Bad HDD/SDD Sectors, configurations, etc... I hadn't transfered and used executables

Or something else changed at the same time.Nothing changed...I did a few copies over the network, verified MD5 checksums failed. Replaced router configured as AP with another router configured as AP, ran the exact same copies and all MD5 checksum passed.
