Home network correction

I have a new house that I believe my alarm system has changed my network design so that it does not work. The way that the low voltage contractor was supposed to setup my network was that one of the network outlets in my office was to connect to my router. From this connection all the other network outlets was supposed to work. I have Direct TV setup on three of my five coax cable connection and one of the connections goes to Cable Company for high speed Internet. My alarm system was supposed to work on my telephone line but I was getting my telephone from my cable company. I believe that my alarm system has changed my network connections to telephone connections. Any suggestions on what I should do to design this system like I need?
I want to have not only a wired network connection but I also want wireless router for our laptops. Any suggestion on how I should configure this? Do I need a switch, patch panel or hub? How should I set these up? I have attached a picture of what is inside my box.

Looking at your wiring there it seems that all your network connections have been converted into telephone (RJ45 vs RJ11, 8 cables vs 2) by twist tying the relevant two cables from each CAT5 cable.

You would need to check the other end too (the socket boxes around the house) to see if they only took 2 cables and cut back the rest (makes this job harder).

You would also need a switch inside that heap of cables to bring it all back together.

It is not really possible to analyze from pictures of cable (no network diagram)

Two things:

1. Try to make a basic diagram of what you want and post it here.
2. I really suggest you get the alarm company back and have them change to what you had. If you change it AND there is an issue, the alarm company might not be liable.

Make a diagram and call the company back.

I no longer have that alarm company. If I could make a basic diagram of what I want I would not be asking this question. What I want is to have a wired and wireless network in my house. So, I need to know what should I do make this happen?

I thought that they had been converted to telephone lines. Would the connection at the wall also be changed to just two cables?

Hook up a Cable to the ISP Modem.

Hook up your main router to the modem and ONE computer by Ethernet to the modem. Make sure it all works. Do not have any other connections to the router. If your router is Wi-Fi, then set up Wi-Fi.

If you have a separate Wi-Fi router:

1. Hook up a LAN port on the Wi-Fi router to a LAN port on the main router.
2. Give the Wi-Fi router a static IP on the main network.
3. Turn DHCP OFF on the Wi-Fi router.

This is how I do it and it works.

Now deal with the alarm.

This is what I think my network should look like. I am not sure if I need a switch or hub to split the internet signal to each network cable.

Route the COAX to the MODEM. Make sure it comes off a splitter and then what you do with the rest is really up to you.

Once you have the MODEM attached to working COAX, then proceed as I suggested above.

Thanks.

There is no need for it to come off a splitter. My television connections are coming off a Splitter from a Direct TV input. The cable coax comes directly in and it is my internet input. From that I am going to connect it to one of the coax cables that is going into one of my rooms. In that room I will connect my modem to that cable. Then I will connect my router to the modem. Next I will connect my router to the network cable that is going into my box. In my box I will have a switch or a hub that will disturb the signal to all the other network cables. Does this sound correct?
Which one would I need a switch or a hub?

I had a friend who just moved to Texas recently that had exactly this issue.  They had capped the wires together just like I see in your photos, but they also, at the wall jacks, pulled the two cables they needed for telephone out of the wall and cut the cable back all the way to the back plate.  He now has to run new cable through his new house to get network because there is not enough room to even put on an extension.

I agree with John, use a switch not a hub.  A hub broadcasts over all ports every packet, a switch will figure out which port requires the traffic (using arp table) and send it only out that port.

You probably have to ask your Secure alarm company for an "IP alarm" system.
The one that does not require phone line.
