Any updates?

[moataz960]

We have the exact behavior with another panasonic module: PAN9028

[jerin-omcare]

In my case disabling the auto deep sleep by setting mwifiex.disable_auto_ds=1 fixed the issue for now. Don't know if this is the right solution.

@jerin-omcare Which firmware version/revision are you using?

@jerin-omcare I am not sure which firmware corresponds to this version: 15.68.7.p189 as I do not find this version anywhere. could you please share the exact firmware revision?

[jerin-omcare]

@moataz960 Extremely sorry for the confusion. That was for a different module. Please see the correct one:

And turning off deep sleep is not an option since power consumption will spike too high and cause elevated temperatures.
