Windows 7: ISP or Networking Issue? 30 days old and counting problem..

ISP or Networking Issue? 30 days old and counting problem..

So let me explain this:

about 30 days ago my internet started cutting in and out. What I mean by that is sometimes the lights on my modem go out sometimes they don't but either way it interrupts my connection and sometimes it will stay offline anywhere from 30seconds-30minutes. The only solution I myself have found is to power cycle the modem when this happens but that only fixes the issue for a short amount of time before it occurs again. ALSO sometimes the internet won't even go offline but the download speed will be less than 1mbps (I'm suppose to get 15mbps)

So...
I called my ISP to figure out the issue and I have had 10 "technician's" out here in the last 30 days. They have replaced all the cords going to my home and inside my home, replaced the modem and router 3 times, and I'm still having the problem.

Today...
They came out here again and replaced the modem/router with a Motorola modem, and a netgear router. All worked fine for about 2 hours and then they called me and told me they were seeing some problems and said since they have done everything that it must be a device on the network. They told me to do this:

"Unplug the router from the network and just leave the modem connected to your hardwire PC for 8 hours, then unplug your hardwire connection and just use the wifi with the separate devices and we will see what happens. I honestly think this is an application you are running that is taking up so much bandwidth which is either causing you to lose connection or get really slow download speed."

Now...
I'm about 7 hours in and I started seeing the same problems and the only thing that was running at the time of the problem were these following applications

League of Legends
Teamspeak 3
Google Chrome

The odd thing is I have had all 3 of these applications running before with no problems...

Ultimate Question..
Is my ISP screwing up or do you think there is something wrong with my desktop that is causing these "crashes"? I appreciate any help you can give me because I am an MLG player and web designer so my work consistently involves being on the internet.

Thank You,
Cael

The thing they need to check if they can access your modem while you don't have connection on your pc. If they can then its something to do with your PC.

Do you have any other PC that connect to it?

Have you tried visiting the manufactures website for NIC drivers?

Can you post an ipconfig /all output from the command prompt
Click start
In search box type cmd press enter
In command prompt type ipconfig /all

well the thing is its both....sometimes they say the modem is offline and sometimes they say it isnt so maybe its both? Here is the ipconfig all!

EDIT: apparently the main thing the network analyst guy I was talking to was talking about is that my network goes through a high amount of packet loss?

Thanks again

You can tell which programs are using the network resources by going into task manager and look in the network processes.

I must say that the extra IP's listed in your DNS are rather strange and suspected as a potential problem.

It looks like somebody entered a few incorrect DNS addresses into the IPv4 properties.

Are you certain that the modem is plugged into the WAN port on the router?

And your DHCP server is a different IP than your default gateway also with an unconventional LAN address. I'm not sure why anyone would want to set up a router in this fashion. It looks like something isn't connected or configured correctly.

This certainly isn't a class of router that I'm familiar with and it's no surprise that you are having problems. Hopefully parman can figured this one out.

Is there anyway I can just reset everything?

Is this with the PC directly plugged into the modem or the router?

I you said that the ISP replaced your modem/router with a modem. Did they also supply you with a new router or are you still trying to use the modem/router as your router.

Let me know these then we will dig deeper.

yes this pc is hardwired straight to the modem currently....I have a router that they gave me but it is currently not connected to the network

EDIT: the router is normally connected to the network whenever I have the issue though and I can try to reconnect it to see if it will help it at all

That explains some of the address.

Lets check some things.
Click start. type network connections in search box press enter.
after dialog box opens right click on your adapter, and select properties.
Scroll down the list and find Internet Protocol Version 4 (TCP/IPv4) and select it.
Choose properties and verify that both IP address and DNS are obtained automatically.

yes they are both selected to obtain automatically.

Here is a screen capture of what is going on with the network from the task manager is this normal?

Next let check network usage.

Go to start menu.
Type resource monitor press enter.
On the top you will see tabs. overview, cpu, memory, disk, network. Select Network.
Let it run for a minutes then post a screen shot of Processes with network activity and TCP connections
