Hello. So, since I moved into my new house in October, my internet has been crap. After several months, I decided my router might be the problem (an old model I literally dug out of the trash a couple years ago). So I bought a new, expensive router and now it's worse than ever. I get a couple of minutes of good internets and then the whole thing starts crapping the bed. I can't stay on XBox Live for more than about five minutes and have to constantly run network diagnostics. Here's my setup:

-NetgearR6300 router
-Motorola Surfboard SB6121 modem
-XBox plugged directly into router
-Laptop and tablet using WiFi

Definitely the router since my laptop is plugged into my modem right now and it works beautifully. So far, I've unplugged everything and plugged it back in, updated all the firmware, changed the MTU size to 1400 (I don't even know what that means), and checked the channels (mine's the only one on channel 1). I am out of ideas. I would do a factory reset but it was like this out of the box. Any ideas??

-Motorola Surfboard SB6121 modem
a PC directly connected by cable to this modem works perfectly with no issues

can we see an ipconfig /all from that PC when connected to the modem - see how below

When you connect the router to the modem , devices connected by cable to the router no longer work correctly , are the issues just intermittent disconnections ?

with a PC connected just by cable to the router and router connected to modem - and only the PC connected
would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
A few tests - so please make sure you also indicate on the reply which tests are for what condition.

Please make a note of the status of the lights on the modem and on the router when working normally - post that light status here.
Now when the internet disconnects make a note of the status of the lights for the modem and router here again. also note which have changed.

ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply
Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the infomation above those entries

We would like to see the results from an ipconfig /all - post back the results in a reply here.

This should work for all windows version, XP, Vista, W7
Hold the Windows key and press R
For Windows 8
to open a Cmd Prompt or an Administrator Cmd prompt from the Desktop. Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.

then type CMD

then press Enter to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results into notepad and then automatically open the notepad and display on your screen.

Now all you need to do is copy and paste those results into a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will now be highlighted
Next
From the notepad menu - choose Edit - Copy

Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
The results from the notepad should now appear in the forum reply.

For your information only
these tests will check various stages of the connection, the first ping test, ping default gateway checks to see if you still have a connection to the router.
The next two Ping google.com & Ping 209.183.226.152 tests the connection to internet. google is to test by name and the ping test using a number is checking that a connection exists without DNS.
these tests then confirm if there is a dns issue on the connection.
