Nighthawk(R) X4S R7800 MD5 Verify Error
Getting an MD5 Verify error when trying to install new firmware. I saw some old posts about this but nothing recent. Any advice appreciated.
Wooohooo! Mine worked correctly. And BTW I did NOT have to do any sort of reset, just went to the update and it worked fine from a Chrome session connected wirelessly.
I'd tend to think that using a hardwired connection for the manual update is safer than using a WiFi connection, because in that case the.img firmware file has to be downloaded on your PC first, then uploaded to the router via the web interface. AFAICT there's no MD5 verification in that case, so if the firmware file gets corrupted during the transfer, this might pass unnoticed by the router, which would then proceed with the installation and might end up in an unbootable or non-functional state.
I guess that using a WiFi connection to trigger an automated update check and installation is less likely to cause such problems, as indeed the firmware download takes place directly on the router and in that case is followed by an MD5 verification.
that would be crazy if it doesn't run that same MD5 check on the manual upload just like the automated update. virtually the same thing, it gets the file in storage and runs the update process. But yeah if it doesn't then a hardwired connection wouldn't be a bad idea for the upload to the router.

I was assuming it doesn't because the MD5 verification error seems to only happen when using the Firmware Update Assistant, and not when updating manually. If the firmware file and the corresponding MD5 hash come from the same source in both cases, that's pretty strange. But indeed, I may have jumped to that conclusion too quickly.
- Yeah hard to tell which it is but my guess is the repository the auto update pulls from isn't the same as the Netgear websites support downloads. They probably put up a corrupted file in the auto updater dir but the correct file in the support site. Who knows though
