That's not the case always. My first cheap thinkpad worked great, but the 2nd expensive one (T440p) has bad driver support for Wifi (on current and last Ubuntu LTS). Connections are unstable and throughput is ~0.3x of the dongle I use (both 2.4Ghz 802.11n). Hardware - Realtek RTL8192EE PCIe.

Always opt for Intel hardware. They have Linux device driver developers on staff. Sometimes the newest chips are not supported, but they always release something within a few months.

Yeah that's what I wanted too but unfortunately the supplier for my company did not have one.

What dongle do you use? I've got a Clevo laptop that otherwise works great w/ Ubuntu, but the wifi is pretty bad.

In case anyone is reading this from a search, I thought I should clarify, the wifi sucks in Ubuntu or Win10, so it doesn't appear related to linux.

Oh OK. My setup is dual boot but I've never had patience enough to spend enough time to test on Win. Just crappy hardware/drivers from Realtek then!

I use a TP-Link TL-WN823N. Did not require any 3rd party driver installs, just plug and play.
