Dear Techies,

I keep loosing my internet connection every 1 - 5 mins. Was hoping someone could help triage me through what is causing this annoyance for me. What are the trouble shooting steps?

Thanks,
-JOHN

What computer are you using? I've had a problem with Dell Optiplex 755 which resulted in them losing LAN connectivity every 5 minutes, this was remedied by updating the BIOS to the latest version

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

What country are you located in.
Name of your ISP (Internet Service Provider).
What is the expected Upstream/Downstream speed for your ISP Connection?
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
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)
Make and model of your computer.
Version and patch level of Windows on all affected machines, i.e. XP-Home (or XP-Pro), SP1-SP2, Vista, 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?

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 to open a command prompt:

Type the following commands:

PING 216.109.112.135

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.

Hi JohnWill,

Thanks for your reply.

I am in USA. I am not sure what is expected upstream/downstream but I can tell you at this moment it is 3500kbps download (5200kbps when connected physically) and 2300kbps upload. Broadband modem is Motorola Surfboard SB5120. Router is Netgear WGT624v2. I am connected wirelessly, one computer is physical, other in house are wireless - I am the only PC facing this difficulty. Not exactly sure about type of encryption, but under "security options" there are 3 choices of (1) Disable, (2) WEP (Wired Equivalent Privacy), and (3) WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) - (1) is selected. My laptop is Gateway MT6705. I have Vista Home SP1. I usually use IE, but sometimes use Firefox too.

What happens is that I loose internet connection every 1 - 5 minutes it seems. I do not notice connection loss while using IE, but it does happen when I use the following programs - Skype will drop calls every time, AIM will log me off then on automatically, any internet gaming will close due to connection losses. When connection is lost, my PC auto-connects again. On a rarity, it will not auto-connect back to the internet - when this happens I restart the modem and router and then I can connect fine, but will go back to the loosing connection thing again. No one else in the house has this problem with their PCs.

On a direct connection I only lost connection on Skype I think - every 10 - 15 minutes. Couldnt tell on AIM due to AIM sometimes being smarter and acting like it is online when disconnected.

Here are the results from command prompt:
