Title: Finding wifi is unstable in this release Status in linux package in Ubuntu: New Bug description: After a recent upgrade noticing wifi disconnects randomly, speeds vary back and forth from 0.1Mbps to 100Mbps within a few seconds, can be up for a few seconds, or a few hours, not predictable. This might be some relevant information, but I looked through the modules and don't see anything like `rtw_8821ce`, there are `rtw88_*` modules which might be relevant, but in any case I can't map these to any packages as far as I can tell. ``` Distributor ID: Ubuntu Description: Ubuntu 23.10 Release: 23.10 Codename: mantic ``` ``` *-network description: Wireless interface product: Realtek Semiconductor Co., Ltd. vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 logical name: wlp2s0 version: 00 serial: b4:b0:24:d4:d7:ea width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtw_8821ce driverversion=6.5.0-15-generic firmware=N/A ip=192.168.2.52 latency=0 link=yes multicast=yes wireless=IEEE 802.11 resources: irq:33 ioport:e000(size=256) memory:f7c00000-f7c0ffff ``` ``` 02:00.0 Network controller: Realtek Semiconductor Co., Ltd.

Like "Have you tried connecting with just wpa_supplicant (and a DHCP client if needed)?" is way over my skill level. ---- This is the relevant output from `iwconfig`, I had just rebooted, as that sometimes helps for a bit, so the stats might not be representative: ``` wlp2s0 IEEE 802.11 ESSID:"************" Mode:Managed Frequency:5.785 GHz Access Point: 0E:**:**:**:**:0F Bit Rate=13 Mb/s Tx-Power=30 dBm Retry short limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=50/70 Signal level=-60 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:92 Invalid misc:0 Missed beacon:0 ``` ---- And another output a few minutes later: ``` wlp2s0 IEEE 802.11 ESSID:"************" Mode:Managed Frequency:2.412 GHz Access Point: 0C:**:**:**:**:0D Bit Rate=58.5 Mb/s Tx-Power=30 dBm Retry short limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=62/70 Signal level=-48 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:9 Invalid misc:1 Missed beacon:0 ``` ---- And after a few hours, note the speed looks really good, but the connection isn't working.
