How to stop broadcast service in Linux?

Connected to network, no internet access, address is ipv4 only, how to fix?

• My network does not have ipv6 capability, which is the norm in my area. Sometimes I can't get internet access and other times I can. The routers have been replaced several times, but we are stuck with the ISP's routers for the internet connection, which we can then extend from with routers of our own. The reason why we are stuck with the ISP's routers is because they double as the modem for the internet service. It's a never ending struggle to try and keep a connection because on some occasions the issue is solved by resetting the router, and other times the solution is unknown.... it just gets fixed somehow later one when I try to rewire the network again or switch (again) to yet another router. I've done driver updating for routers, network cards, and the OS, disabled and enabled the wireless and networking cards, manipulated Windows services, changed the IP settings between manually setting them and telling them to automatically detect, restacked the TCP/IP protocol, reset the IP address, released the connection, reset the routers, and switched between them. I have ended up getting 3 different connections between 2 ISPs, just to try to maintain internet so I can keep looking for information on fixing this issue. On some occasions, I have been able to connect and get internet access with my Linux system at times, when I would do the same with Windows, but get no access. This is not usually the case, though. The computers that are directly connected (wireless works almost as well and wired, doesn't have this problem nearly as much, but a direct wire straight into the ISP router goes through without any failure) don't seem to have any problems getting through to the internet, but when I try to get a connection from the rest of the network, I can get a connection for a few hours at the most. I've done ping testing to see how far the connection can get, and apparently I can get to my routers, but sometimes I can't get a response from the ISP routers. When I can get responses from them, the connection can never get past them onto the actual net so I can just have a decent connection and not have to worry about always being plugged into an ethernet port. Now I have a new weird thing happening, not that it helps any, I'm connected to the wireless router, and I have a wired only hub that goes to the other connection. Connecting wirelessly to the router gives me no internet connection, but I get network access. Connecting to the hub while keeping the wireless connection gives me a connected to the internet reading on both at the same time, meaning that all of the sudden the wireless reads "connected", but when I unplug the ethernet from the hub, it goes back to no internet connection. How can I fix this so I can finally stop working on this network connection so this can finally be a resource, and not a project?

• Answer:

  The one thing I did not see in your post was anything about DNS. 1> Check to make sure your computer is set to auto detect IP addresses, and DNS addresses. As long as this is supposed to be the way things run, then do a ping to a domain name. If that does not work, find a site with a known IP. If you CAN ping the IP but not the domain name...it is a DNS issue. Could be on your computer, your router, or the ISP side. It could be some other things, but this is the first I would check.
