Problems uploading files and editing configuration in browser

I have been having problems uploading files and making changes to config.g in the browser since I started using my Duet2 WiFi and they seem to be slowly getting worse. I applied the latest DuetWiFiServer firmware, just in case that had anything to do with the problem, but it has not had any effect.
I also tried swapping out the provided 4GB class 10 microSD card with a known working 8GB class 4 card. This had no effect.
I just went back to the original card after making sure that the contacts on the card and in the socket were perfectly clean with some blotting paper and isopropyl alcohol. After the Duet had booted, I checked M122 on the console and then uploaded a 4.7MB g-code file.
The upload seemed to go OK, but looking at M122 directly afterwards shows SD card related errors:

Have you also updated the DWC to 1.22.6?
-60db signal strength isn't too bad, but it's not great. If you can improve the signal strength by moving the router or printer, even temporarily to test, that may be a cause.
Try formatting your SD cards with https://www.sdcard.org/downloads/formatter_4/ with 32kb or 64kb cluster size.
Also, clear your browser cache, etc. Or try a different browser to see if the same thing happens.

All firmware is the latest versions from GitHub.
The fact that both the card supplied with the Duet, and a known good spare both exhibit the same problem would probably excuse the card, but I will give it a try with a brand new, straight out of the packet card, just in case. The Duet is certainly not having any trouble reading from either card as I'm having no problems printing files from them.
The router is no more than 2.5m from the Duet, which has the WiFi antenna sticking up out of a slot in its plastic housing. The devices are in sight of each other, so If -60db is too low then I suspect there might be something wrong with the Duet's WiFi board. I'll try removing the Duet from the case. I don't suspect green PLA to have any strange properties like completely de-tuning the WiFi board's antenna, but you never know with microwaves!
