Got a problem with my connection, it keeps disconnecting every 10 minutes or so, usually at the same time every day. Lasts for a few seconds but does not show as an interruption to the line's uptime, nor is there a warning sign in the system tray (like what usually happens when there's a disconnection).

-ISP says they do not see any problems on their end
-Updated router firemware, no dice
-Router is a Netcomm NB6PLUS4W modem/router
-Tried with both wired and wireless connections, same problem.
-I keep getting error 400 bad request while browsing the router setup page.

Any ideas?

Is this the only PC that disconnects - do other devices connected work OK

it keeps disconnecting every 10 minutes or so,
buts just for a very short period and logs straight back in and works again - you dont need to do anything to get it to work again - correct
-I keep getting error 400 bad request while browsing the router setup page.
are you using internet explorer to access the router - I know some can be fussy

try this program
http://code.google.com/p/internetconnectivitymonitor/
and ping google.com - that should show if a discconect occurs

we could use ping -t google.com -but this is a free program and can just run on the PC

Unfortunately i have no other devices to test with. But i just moved into this apartment and my internet worked fine in the old apartment.

Correct, i do not need to do anything to reconnect.

Im using firefox to access the router setup page.

What do i do with the program? Just run it? Or do you want me to paste something?

put in the address www.google.com and also the time and then it will just continously test the connection to google and see if it disconnects

then we need to try an ip address of a site
and see if that works OK and if thats ok ,then its a dns issue

i would suggest yahoo.com - to find out the IP address

Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

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.

Type the following command
Ping yahoo.com

make a note of the IP number you get back - and then use that in the application


post back some screen shots


To post a screen shot of the active window.
1) hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
OR
2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.

I ran the logger but it doesnt detect any disconnections even though i was getting disconnected from IRC, i had my downloads interrupted, etc, etc.

I then tried the yahoo IP and here are the results :

have you downloaded the driver from the manufacturers website and installed - not just do an update

also that IP should reply OK
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, Mcafee , AVG , Webroot etc

yes, but still needs to be removed, last year we saw issues of trailware Norton, which had been uninstalled in 2007 still cause issues and the removal tool is needed.

No, i haven't tried downloading any drivers, what drivers are yo ureferring to?
the network adapter drivers

whats the make and model of the PC
can we see an ipconfig /all
------------------------------------------------------------------------
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.

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

This should also work for windows 8
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:
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.

I haven't installed any trialware between moving out of my old apartment and into this one, and the problem only started occuring at this apartment
we have seen unrelated changes, that have suddenly meant an old version on the PC and part of the pre-installed software - suddenly cause issues - so its worth looking into

we are looking for the driver for the
Broadcom NetLink (TM) Gigabit Ethernet
adapter

the driver is here
http://support.lenovo.com/en_US/downloads/default.page?

three versions on the site for different windows version

XP =
http://download.lenovo.com/UserFiles/Driver/en/Downloads and Drivers/Y460pY560p/XP/IN8ETN04WW1.exe

W7 64bit = http://download.lenovo.com/UserFiles/Driver/en/Downloads and Drivers/Y460pY560p/IN3ETN41WW6.exe

W7 32bit =
http://download.lenovo.com/UserFiles/Driver/en/Downloads and Drivers/Y460pY560p/IN3ETN41WW5.exe

download the file and do an installation - dont use the update facility on the device manager - adapter - properties screen

look in programs for things like

Norton or Synamtec, Mcafee, Kaspersky = are the most common security suites that are supplied and running on the PC
others to look for would be

AVG,
Webroot,
zonealarm
trendmicro
