WiFi no longer connects on startup for Realtek chipset adapters #53

Open brandon-arnold opened 6 months ago

brandon-arnold commented 6 months ago

At some point in the past month, the Linux MiSTer distribution stopped connecting to WiFi with the MiSTer Addons WiFi + Bluetooth Adapter. This is a common Realtek Chipset rebrand.

After witnessing this on one system, I performed the same udpate on another outdated system with the same model WiFi dongle. It also is no longer working upon reboot, so I feel confident I could downgrade and that would fix the issue.

Here are the listings for both adapters

# ls usb | grep 802
Bus 001 Device 008: ID 0bda:818b Realtek Semiconductor Corp. RTL8192EU 802.11b/g/n WLAN Adapter
Bus 001 Device 006: ID 0bda:c820 Realtek Semiconductor Corp. 802.11ac NIC

Kuro Houou pointed out that upon starting from the system completely powered off, WiFi will connect if the Ethernet is plugged in first (confirmed using ip addr, showing both adapters getting IP addresses). I have confirmed this for both adapters.

I/O boards tested and confirmed: Jammix MiSTer Ironclad+ Retro Castle dual-ram

Here are various versions I have today, after updating: MiSTer v240110 OS v231108 Linux MiSTer 5.15.1-MiSTer 1 SMP Wed Nov 8 16:41:16 CSG 2023 armv71 GNU/Linux

the same thing happens to me with 2357:012d TP-Link 802.11ac NIC [Realtek RTL8812BU] before it always worked perfectly but now it has stopped working. https://www.amazon.es/dp/B07M69276N?psc=1&ref=ppx_yo2ov_dt_b_product_details
