Esp32 firmware 1.17 with spiram WIFI issue

[eldstado]

Hi
I've been using firmware 1.14 with spiram build on IDF 3.x and its been working fine on esp32 wrover-b.

After updating to v 1.17 build on idf 4.x there is some problems using WIFI. if router uses default DHCP_LEASE time (7200 secs) the board looses connection exactly every hour(half the lease time) and reboots(my code)

if I set another dhcp_lease time, it works okay. For example if I set lease time on router to 3600 it works as it should.

Any idea why?

Still same issue om v18. Nobody else seeing this problem?
