    Wirelsss usb stick cant connect but OS sees it

    I have a Samsung wireless Usb LAN stick.

    I just installed Kubuntu 17.04 KDE Plasma 64 bit

    And when I plug in the stick KUBUNTU sees it. I can see available connections , I can connect to my home Acces point.
    However when it connects it will time out and say Connection deactivated?

    I use this same stick on the same machine (OPTIPLEX 755) using UBUNTU MATE and ELEMENTARY LOKI os's and it works fine.

    Ethernet connection has no issues.

    Can anyone help?
    It seems something is blocking the the connection?

    Do you (or did someone or something) set up a proxy? I've seen browsers & their plugins set up a "localhost 21320" proxy connection that then results in a msg claiming that the destination "rejected the connection". In fact, this morning (!) I was removing a bunch of adware, two trojans and redundant anti-malware from a friend's Win7 and saw a msg at the bottom of FireFox stating "Connecting through a proxy ...". When I removed the proxy setting the msg went away and Internet response increased significantly.

      I did not set up a proxy. I use FIOS internet connection provided by Wireless router ISP. I use firefox as web browser on KUBUNTU. Will Firefox set up proxy with out me doing it?

        The proxy on my friend's computer was setup without his knowledge or approval. He suspects it may have been due to either the AV product or a visit to a particular website. Windows is so promiscuous, you know.

            sudo netstat -tunap

            Netstat will give a listing of IP addresses (w.x.y.z) followed by a number (w.x.y.z:631 the number is the port) and followed by the program that is "WAITING" or "LISTENING" on that port. 21320 is a common port for a localhost proxy. I've posted a list of ports below:

            Also, you can use wget:

            My IPv6 connection to Google.com is via port 80. If you get something else besides 80 then you may have a proxy setting. If you don't have IPv6 then you will see something like this: 192.168.1.104:80
