Metro ESP32-P4 wifi issue/packet loss

The report names CircuitPython 11.0.0-alpha.2 on the Metro ESP32-P4 and shows intermittent ping, DNS, and HTTPS failures, but it does not identify a failing source file or test. Start by locating the ESP32-P4 Wi-Fi driver and its networking tests, then compare connection and request behavior with the ESP32-S2 results in the issue. Done when the cause is isolated and the reported network operations work reliably on the Metro.

CircuitPython version and board name

Adafruit CircuitPython 11.0.0-alpha.2-22-gbe6f0a678b on 2026-10-27; Adafruit Metro ESP32-P4 with ESP32P4

Behavior

the Metro is able to connect to wifi, but when it tries to fetch data it throws errors or can be extremely slow. here is the result from our usual circuitpython wifi test (the two networks are my local ones):

My MAC address: ['0xd4', '0x5', '0x92', '0x9', '0xc', '0x8c']

Description

i also ran the same code on a feather esp32-s2 and got these results (same location, router is right outside open office door)

Done

i also tried an adafruit io example (https://learn.adafruit.com/pico-w-wifi-with-circuitpython/pico-w-with-adafruit-io), replacing sensor data with ints and timed how long it took to fetch feeds with time.monotonic():

connected to io
now: 184.887, from start: 0.004974366
feeds created
now: 357.666, from start: 172.784

was also seeing the same OSError: (-29312, 'MBEDTLS_ERR_SSL_CONN_EOF') from the IO test or a timeout error

Additional information

i did try switching between my 5ghz network and 2.4ghz iot network, same results. also turned off web workflow to rule that out.
