Public bug reported: [SRU Justification]
[Impact] On the intel ADL-U platform, the rtl8821ce suffers the beacon loss frequently because the driver doesn't received any beacon from AP. It causes the wpa-supplicant to reconnect again and again. [Fix] Realtek release a fix to disable the PCI completion timeout on rtl8821ce so the PCI bus won't get stuck and can handed the received packets to the driver correctly. [Test Case] 1. Connect the WiFi to internet by selecting a internet connected AP 2. ping 8.8.8.8 to check the internet connectivity for at least 5 minutes. 3. Make sure no 'CTRL-EVENT-BEACON-LOSS' event reported from wpa_supplicant [Where problems could occur] Risk should be Low. It's only applied for RTL8821CE to disable the completion timeout capability. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.17 (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux-oem-5.17 (Ubuntu Focal) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Affects: linux-oem-5.14 (Ubuntu Jammy) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.17 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.17 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-oem-5.17 (Ubuntu Focal) Status: New => Invalid ** Changed in: linux-oem-5.14 (Ubuntu Jammy) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.14 in Ubuntu. https://bugs.launchpad.net/bugs/1969771 Title: Fix beacon loss for rtl8821ce on certain platforms Status in linux package in Ubuntu: New Status in linux-oem-5.14 package in Ubuntu: Invalid Status in linux-oem-5.17 package in Ubuntu: New Status in linux source package in Focal: New Status in linux-oem-5.14 source package in Focal: New Status in linux-oem-5.17 source package in Focal: Invalid Status in linux source package in Jammy: New Status in linux-oem-5.14 source package in Jammy: Invalid Status in linux-oem-5.17 source package in Jammy: New Bug description: [SRU Justification] [Impact] On the intel ADL-U platform, the rtl8821ce suffers the beacon loss frequently because the driver doesn't received any beacon from AP.
