Title: Wireless card with Intel AX200 chipset downloading very slow on Ubuntu 20.10 Status in linux package in Ubuntu: Incomplete Bug description: Hi, I've recently bought a wi-fi card based on Intel AX200 chipset and it is extremly slow if compared with same network performances on the same ssid (and at the same distance from router) on other devices. These are the details of my network sudo lshw -C network; lsb_release -a; uname -a *-network description: Wireless interface product: Wi-Fi 6 AX200 vendor: Intel Corporation physical id: 0 bus info: pci@0000:04:00.0 logical name: wlp4s0 version: 1a serial: 8c:c6:81:19:40:65 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=5.8.0-31-generic firmware=55.d9698065.0 cc-a0-55.ucode ip=192.168.100.8 latency=0 link=yes multicast=yes wireless=IEEE 802.11 resources: irq:16 memory:febfc000-febfffff *-network description: Ethernet interface product: AR8121/AR8113/AR8114 Gigabit or Fast Ethernet vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: enp2s0 version: b0 serial: 00:24:8c:37:c6:3c capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=ATL1E driverversion=5.8.0-31-generic firmware=L1e latency=0 link=no multicast=yes port=twisted pair resources: irq:17 memory:fe9c0000-fe9fffff ioport:dc00(size=128) *-network:0 description: Ethernet interface physical id: 1 logical name: virbr0 serial: 52:54:00:50:fd:ef capabilities: ethernet physical configuration: autonegotiation=off broadcast=yes driver=bridge driverversion=2.3 firmware=N/A ip=192.168.122.1 link=no multicast=yes *-network:1 DISABLED description: Ethernet interface physical id: 2 logical name: virbr0-nic serial: 52:54:00:50:fd:ef size: 10Mbit/s capabilities: ethernet physical configuration: autonegotiation=off broadcast=yes driver=tun driverversion=1.6 duplex=full link=no multicast=yes port=twisted pair speed=10Mbit/s No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.10 Release: 20.10 Codename: groovy Linux mirko-P5QL-PRO 5.8.0-31-generic #33-Ubuntu SMP Mon Nov 23 18:44:54 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux I've tried many of the solutions found on the internet: - setting the option 11n_disable=1 (slightly improved but still slow) - setting the option 11n_disable=8 - edit /etc/nsswitch.conf commenting the line "hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4" and adding the line "hosts: files dns" - disabling IPv6 support But results are still the same and connection keeps being slow (no more than 15 MB/s vs. 300+ MB/s on my smartphones using the same network). I hope you can help. Thanks.
