Subject: Issues with rtw88_8821cu Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Precedence: bulk List-ID: X-Mailing-List: linux-wireless@vger.kernel.org Hi, I'm seeing some issues with a BrosTrend AC650 adapter (rtw88_8821cu). I have all the recent fixes, up to and including commit 4a267bc5ea8f ("wifi: rtw88: use RTW_FLAG_POWERON flag to prevent to power on/off twice"). 1) rtw_8821cu 1-3:1.0: Firmware version 24.11.0, H2C version 12 rtw_8821cu 1-3:1.0: failed to download firmware rtw_8821cu 1-3:1.0: failed to setup chip efuse info rtw_8821cu 1-3:1.0: failed to setup chip information This first issue is related to USB errors. Generally, it starts with the "failed to download firmware" followed by an assortment of other "failed to" messages. At this point the adapter may show up in iw, but is unusable until unplugged and replugged. 2) The second issue is unusably low Rx signal levels on the 2.4 GHz bands. The scan results report about 30dB to 50dB lower than adjacent adapters. That's if the 8821cu can even detect the beacons. 3) The third issue is that, in IBSS mode, the adapter cannot receive any packets or see adjacent IBSS nodes. iw station dump shows no results, unless also running a scan. Even so, ifconfig shows 0 Rx packets, and the adapter is not able to receive. This happens in either noHT, HT20, or HT40 modes. Where do I begin getting these running? Alex
