I am very new to linux and very new to the CLI. I am running Ubuntu 14.04 LTS. When I was running from disk my wireless worked fine. Now that I have installed the wireless connection works intermittently, and when it does work the speeds are not good. I am currently tethered to my cellphone, and have a pretty good connection. I have run the following commands:
lspci > ~/hwinfo.txt lsusb >> ~/hwinfo.txt lshw -C network >>
~/hwinfo.txt
And here is the
result:
lspci > ~/hwinfo.txt lsusb >> ~/hwinfo.txt lshw -C network >>
~/hwinfo.txt
And here is the
result:
