Hi, Am I correct, that your computer's IP is 192.168.0.19 (you can check it with *ip addr*)? It doesn't seems so, since there are no ARP replies from (presumably) your router. If it is, then for starters I would suggest to find the guy who sends UDP broadcast on port 75. To do this you can use *netstat* and check for any suspicious activity*:* *# sudo netstat --all --udp -4 --program*
Also, check that your computer doesn't run dhcp server, that could misguide other clients. At home you can try to run wireshark to find out what happens with HTTP requests or you better follow some basic network troubleshooting guides like this <https://ubuntuforums.org/showthread.php?t=25557> one or this <http://searchnetworking.techtarget.com/tip/Wireless-network-troubleshooting-Connectivity> one, or, maybe, this <http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch04_:_Simple_Network_Troubleshooting#.V-pukXV95vA> one. -- Pavel вт, 27 сент. 2016 г. в 10:05, Taeer Bar-Yam <[email protected]>: > Okay, I got wireshark.
