I'm a new Ubuntu user trying to get my wifi working properly.

How do I install a downloaded driver?

After changing some configurations in my router I'm able to get 5Mbps on my laptop (but +100Mbps on my smartphone)

I've also followed this whole itsfoss tutorial but I'm still not getting the full speed.

Recently I've found the proper driver on intel.com.

I've copied the iwlwifi-1000-3.ucode file to /libfirmware

But I guess my wifi is still using the generic driver.

$ lshw -C network

  • Are you using a USB dongle or a built-in PCI device? Why do you thiing you have an Intel device? There is absolutely no information about your device in your question.

  • Sorry, guys. My mistake. I'll update with lspci -knn | grep Net -A3; rfkill list. And the right part of lshw -C network Commented May 12, 2020 at 22:41

Sorry, guys! My mistake.

By executing: $ nmcli dev wifi list

1. I've realized it was a router configuration.

It was only 802.11b (limited to 11mbps).

I've changed to 802.11n (up to 130mbps).

2. I've also realized that

There is a bug on Intel Support for Linux Page. The Intel® Centrino® Wireless-N 1000 firmware versions are switched between Kernel versions 3.2+ and 2.6.30+.

Then I've followed this steps:

$ tar -xvzf iwlwifi-1000-ucode-39.31.5.1.tgz 
$ cd iwlwifi-1000-ucode-39.31.5.1/
$ sudo cp iwlwifi-1000-5.ucode /lib/firmware/
