I haven't attempted to apply the .chk file because the extension description suggests that the file may have problems. It is not a .img file.
For unknown reasons, Netgear uses both .img and .chk as file extensions for firmware.
These are both open to confusion because there are other types of .img and .chk file – .img is a disk image and seems to confuse macs in particular while .chk is also a Windows "recovered file fragments" file.
Firmware for the WNDR3400v3 is, indeed, a .chk file.

How do I manually upgrade firmware to my NETGEAR router? | Answer | NETGEAR Support
Also, the manual shows a screen shot of the page where there are options to check online or upload from PC, but it only describes the check online option, which isn't working.You need to read a bit more of the manual. It also describes the manual process in the section Upgrade the Router Firmware. But it wrongly tells you to look for an img file. That's what you get when you copy and paste between manuals.
The manual may get things wrong, but the update process will protect you and prevent you from applying the wrong firmware.

Successfully updated firmware. Now to see if that has resolved the intermittent connectivity and audio issues I've observed...

That's good news.
But don't expect a lot. The WNDR3400v3 dates back to 2014 with the first version in 2010.
According to Netgear's manual for this device, not always the most reliable source of information, the LAN and WAN ports support only 10BASE-T or 100BASE-TX. That makes it slower than many newer internet services and most modern network hardware. This may not matter to you, but be warned that it will hobble you if you ever sign up for faster Internet. It also slows down whatever is going on in your local network. Newer devices support at least 1000BASE-TX.
