The Wireless Network controller: Qualcomm Technologies, Inc QCNFA765 Wireless Network Adapter (rev 01) in my t1g3 has not been working well for me.

I think a fwupdmgr upgrade might have helped, but I’m not sure. I’m on the latest firmware:

        New version:      0.1.52
        Remote ID:        lvfs

        Urgency:          High

Slow with latency

Can never seen to get higher then 50 Mbit/s whilst my Mac M1 Pro can easily get 300 Mbit/s and above.

Noticed my @archlinux T14 wireless ping times are 2x that of my Mac pic.twitter.com/vqe0o5u073
