I am currently searching for answers from Intel and Lenovo support communities, since there seems to be no more troubleshooting to be done in terms of networking. It is strange that a phone's WiFi6 adapter is outperforming these brand new Lenovo laptops. ... View more

Running Iperf again with your recommendations, top is TCP test: I managed to get my hands on another Wifi 6 client (a Samsung Galaxy S20 FE). Speedtest manages to push ~700 mbps dl ~350 up, interestingly enough. This may be an issue with the Intel WiFi 6 AX201. I will attempt to upgrade firmware on the Meraki. Power as shown in Meraki dashboard is: 12.01 W / PoE 802.3at. We have 2 MR56 APs that have both been tested identically, with similar results. ...

Was running latest Lenovo provided: 22.0.0.6. Recently installed Intel's generic driver: 22.40.0.7. No improvements noticed. Moved to a clean channel - no improvements noticed. Here are results of Iperf testing on local network, first is wifi 6 client to wired server. Second is wired client and server:           ... View more

Thank you, I will attempt those suggestions, I did not see any option in power settings for WiFi performance and assume it was removed in a recent release. As for the channel width, it was selected automatically by the AP. I will attempt to lower it to 40 MHz and see if that helps. ... View more

Meraki MR56 AP Speed Issues

We have recently purchased and installed 2 new Meraki MR56 APs on top of our existing network, and are finding we are having performance issues when clients are connected. We have a 1gbps dedicated fiber connection, and WiFi 6 clients are only getting top speeds of ~280 mbps (Meraki/Ookla speedtest). Device: Cisco Meraki MR56 Firmware: MR 27.6 Upstream devices: Netgear GS324TP switch, SonicWall TZ500 Client device tested: Lenovo Yoga 9i, Windows 10 Pro, fully updated (Intel Wi-Fi 6 AX201 adapter) There is currently only one client device connected to the AP for testing. The AP connection to switch is recognized as 1000 Mbit full duplex. It is running in bridge mode. Set to 5Ghz band only, channel width 80MHz, minimum bitrate 12.  Meraki dashboard reports acceptable utilization on current channel (~10%). Signal strength is good (~35dB). I have checked our SonicWall firewall settings and I am able to get ~900mbps when directly connected to it, we are not using VPN or DPI. I am also able to get ~900mbps speed directly connected to the switch. Connecting AP to same switchport with same cable, top speedtests are around 280 mbps. If I'm not mistaken I understand WiFi is half-duplex so I should at least be seeing speeds of closer to ~400-500mbps for our WiFi 6 client, correct? Any advice or tips to optimize our performance would be greatly appreciated. Thank you! ... View more
