Network Connection Drops When Downloading

[DroppedHonda]

Every so often while i am downloading a rather big file my network connection will just drop out. When this happens i have to go through the process of clicking on network diagnostics and it will reconnect telling me my default gateway was not available. I am running Windows 7 64bit and using firefox, it is all on a wired connection.. If you need more info ask,, thanks in advance

Please supply the following info, exact make and models of the equipment please.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
Make and exact model and hardware version of any other network equipment, like a repeater, a booster, hi-gain antenna, etc.
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.
If wireless, encryption used, (none, WEP, WPA, or WPA2)
Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
The Internet Browser in use, IE, Firefox, Opera, etc.




Please give an exact description of your problem symptoms, including the exact text of any error messages.

• If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
• For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
• For wireless laptops, have you made SURE the wireless switch is on?
• For wired connection issues, have you booted in Safe Mode with Networking to see if that changes the symptoms?
• Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
• If there are other computers on the same network, are they experiencing the same issue, or do they function normally?

On any affected computer, I'd also like to see this:

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

Type the following commands on separate lines, following each one with the Enter key:

PING 74.125.45.100

PING yahoo.com

NBTSTAT -n

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

OK, so the computer doesn't know it's disconnected.

Let's expand that and do some pings next time it disconnects.


Try these simple tests.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

Do NOT include the <> either, they're just to identify the values for substitution.

IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 74.125.45.100

PING yahoo.com

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. (For Vista/Win7, the IPv4 Address)

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

That almost appears that the NIC is dying.

When it stops, are the connect lights on the NIC and the router port still active? Have you tried a new cable and a new port on the router?

[DroppedHonda]

No i havent tried that,, but i will. Thanks for the help
