I'm having this same problem.
I can save and forget networks as long as the wifi module has been set to active with m552 S0, but not with S-1 or S1 modifiers. When I try to check the status of the wifi module with M552 by itself, I consistently get "wifi module is changing modes" until there's an SPI timeout message like the one at the bottom of the excerpt below.
I've successfully reinstalled wifiserver.bin twice (i'm doing this over USB with pronterface and a 24vPSU for the board), but this has yielded no changes in anything. If I just let it sit, it'll eventually give me a bunch of these in a row:
WiFi module is idle

Error retrieving WiFi status message: SPI timeout

Failed to change WiFi mode: SPI timeout
Once the SPI timeout message(s) come, m552 reports that the wifi module is disabled.
I know it's not a poor signal issue, as I've tried within a foot or two of the router.
Here's my m122 if it helps:
