Intermittent internet connection, sometimes for hours sometimes seconds.
ISP has serviced site 2x, changed port 1st time, separated cable tv and broadband 2nd time.
Modem receive power was -2.5 to 2.9, now 10dBmV snr 36 to 41 dBmV.
Drivers are all up to date. I have pressed ISP for an engineering response. They are brutally slow to respond. Problem 30 days old at the moment. My gut tells me it is ISP issue at router bank but speculative. Any help out there?

is this a company setup

can you describe how you are connected to the internet all devices make and models of the modem and router ?

you seem to have a DHCP server address -
if company then a little outside my knowledge - but other members will need the above information anyway

would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
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 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 here again. also note which have changed.

What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, kaspersky or Mcafee or any free security suites like zonealarm, AVG , Webroot etc

ipconfig /all
Three Ping tests

------------------------------------------------------------------------
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.

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.

This should work for all windows version, XP, Vista, W7
Hold the Windows key and press R

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:
all the text will now be highlighted
Next

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.

Note: This the 1st time gateway has shown drops, on previous tests it only showed time variations from 7ms to 375 ms
Note: when operational Modem lights on are power,cable. Flashing lights are PC, data receive and data send.
Note: When down lights on are PC, Cable, Power. No flashing lights
Note all this info is duplicated above with the exception of the gateway data which had been done but not included as it did not show consistent issues. Thanks for your patience.

i would re-install the Atheros AR8151 driver - NOT an update but actually install the driver
whats the make and model of the PC
you should be able to get the driver from the manufacturers website - preferred option
or from here

http://www.atheros.cz/atheros-network-drivers.php

You need to look down the page for your particular adapter model and then look across the columns to find your windows version.
Now click on the blue tick mark in the column under your windows version.
This will open another page for that particular adapter and that windows version.

To install the driver you will need to do the following

then

> Start Globe
> Control Panel
> System and maintenance
> Scroll down to Device manager
> network adaptors, click on the + >
> Right click on the AR8151 Adapter
> click on Update Driver Software...
> click on Browse my computer for driver software
> let me pick from a list of device drivers on my computer
> Have Disk
> click on the Button Browse...
> Locate the folder you extracted the zip folder and highlight the .inf file
you should see files with .inf

No help loaded new drivers per web site but no joy. Also have dvd with drivers sent with asus mainboard and windows itself declared i had the most current driver. Will leave it for am to see if it helps any then. Thanks for your efforts I am becoming convinced that the fault is at isp but as yet cannot point with certainty to their issue.

As Seen On
