Someone here recommends an Intel replacement for the Broadcom.
https://www.ctrl.blog/entry/replace-broadcom-wifi-with-intel.html
Those are tiny tiny looking connectors. No wonder they
regularly get squashed during install.
https://www.amazon.ca/AC1200-Wireless-7260NGW-7260AC-Network/dp/B07VCBRB4B
They make RP-SMA cables, but on a laptop there would hardly
be room to fit those on the chassis.

My consistent cable connectivity on speed tests on other hardware in Mbps is ~ 200 down and ~ 12 up. On the Lenovo, no matter whether the OS is Win or linux, checking 3 different speed test sites, the performance ranges 40-80 down, 12 up. Its ethernet is reported Realtek RTL 8111/8168/8411 PCIe gigabit ethernet controller using r8189 driver in linux. The topology is the same for the good results as the poor ones, to a gigabit switch on a gigabit router to the cable modem. -- Mike Easter

First thing I would check is _any_ nic errors.
ifconfig enp3s0 | grep err
RX errors 0 dropped 0 overruns 0 frame 0
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
I had poor performance with single digit number here and there.
after playing around with iperf I changed out the cheap ethernet cable
to a higher quality and got much closer to my gigabit lan speed.

That test/check is OK. -- Mike Easter
