Internet Connection lost

November 2, 2005 at 12:42:51
Specs: WinXp Pro, 3200+ Athlon

I have a network that works fine but for some reason when I assign a Static IP address to one of my computers the internet connection would die after a few hours for everyone, although everyone can communicate with the network. The only way to get back connected is to unplug the router then plug it back in. Any Suggestions?


Computer: 3200+ Athlon, 1gig Ram, ASUS Deluxe Board, Radoen 9800 etc
The computer is connected via Cat 5 cable to a Linksys Router (WRT55AG). I have enabled port forwarding on the router (for bitcomet) plus I have enabled the same port (TCP and UDP) on my computer to bypass windows (stupid) firewall. Prior to having the computer become static I have not had a problem. I have a cable modem and my ISP uses dynamic IP addresses. This happens day or night, and I can not figure it out. I also noticed this happened more once I added another PC to my network even though he is using dynamic IP addressing from the DHCP from the router. (This last point might not be significant but I thought I would add it just in case).

First off - "die after a few hours for everyone". Who is everyone and what environment is this? Work, home?

98% of the population is asleep. The other 2% are staring around in complete amazement, abject terror, or both.

If you have to reset the router why would you think it relates to your static ip assignment on a workstation?

Sounds like a problem with the router/isp and not a workstation.

This is a home environment and when I say everyone I mean all 4 of "us" at my home.

I think it relates to my static IP because I have only noticed this happens after using a static IP address.

I am going to test this tonight by doing dynamic but this would not help my problem completely.

If you think you have it all figured out why are you asking us?

How, in your mind, do you relate one assigned ip address to killing the connection for all? How do you think this relates?

You aren't trying to assign the same address the gateway [router] uses are you?

I am trying to wonder why you wrote "If you think you have it all figured out why are you asking us?"

I am asking the question because I do not know why my network runs fine (able to browse both network shares and Internet) when I have 4 computers hooked up to a linksys router and all the computers are using dynamic IP addresses, but the minute I assign a static IP address to one of the computers the internet connection drops within a few hours sometimes even quicker (but I can still browse network shares).

I never said I had a solution I was only stating what observations I noticed as I thought that would help with finding a solution!

With regards to why in "my mind" I relate one assigned IP address to killing the network connection is because that is the only change I have made before the problem started. So from a common sense point of view I thought that might be one possible reason.

And no I am not using the same IP address as the gateway router. I am hoping for a suggestion.

Another thing maybe I should have written this "I am going to test this tonight by doing dynamic but this would not help my problem completely." another way. I said this would not help my problem because if it drops then I still have a problem but at least I would know it is not IP related but if it does not drop then it might be IP related. So I am just looking for suggestions or maybe just to know if this makes sense in doing.

I took a different view on your post but clearly that was incorrect. Sorry about that.

What is your gateway address and what is the static ip you are assigning?

there is no difference between a static ip than a dynamically supplied one.

that is as long as they are in the same subnet. A ip address or its assignment won't make a router fail. You can even get the router to assign each pc a particular ip address as if it were static but supplied by dhcp.

now if you assiged it the gateway address you would cause a ip conflict and both interfaces would be disabled.

I take your "although everyone can communicate with the network." to mean that all 4 pcs to still talk to each other but not get to the internet.

If this is the case this means the switch part is working but from that part on something is broken.

Next step is when the internet goes down but all the pcs can communicate, can you get to the routers web interface?

If you can look to see if you have a ip address on the wan interface. It would be either the router or the isp. No ip on the wan interface would point to the isp.

Other tests can be done if we get to this point to isolate the problem.

Ok this is Fine, so far I have gotten the dynamic assignment going and the PCs are still connecting to the internet.
Ok my gateway address is and my static is Now that I am writing this I forgot that I have a computer on my network that I use only for printing (I guess a print server) and this address has always been static ( I also checked my router and I have automatically assign IP addresses from – This makes me now think that it must be something else because this static address has been used forever.
And yes you are right when I say no one can get on the internet I do mean no can get online but they can still talk to one another.
So I am basically going to take you advice and wait for the internet to go down and then
• First check to see if I can get to my router interface
• Double check to ensure that I can communicate with other computers on the network still.
• Check my IP address the ISP (Rogers) gives me as well to ensure it is valid (because I do remember like 1 month ago I saw that the ISP actually gave me a 10.X.X.X. IP address and I was freaking out because I know this is not an external routing IP address.

Thanks for the suggestions will definitely keep this post updated.

Sounds good. I am impressed that you know 10.x is private ip and not public. Good catch. It will be interesting to see where this goes.

Well tonight so far I have not lost connection so I am going to see if this lasts for another night. If it does then tomorrow I will go static and see what happens. I am also interested to see what happens here. Especially being it makes no sense for a static IP address to stop my linksys router from working.

Ok unfortunately my connection died last night (at 2:17am 10 mins after I was using it) without the static IP address but with the dynamic address. What I done when I discovered this out this morning was:
• Tried to Ping every computer on the network and it was successful
• Tied to ping the router but no success
• Was able to browse the network share folders
• Could not log into the router interface
• Could not get onto the internet
• I was able to use remote desktop for another computer on the network (that has a static IP address)
• The IP address assigned to my main computer had not changed it was still
• Looked at the event log and took note of the errors which were as follows:-

This is often caused b by services running as a user account, try configuring the service to run in either the LocalService or Network Service account.

Now I am at a lost for what I should do next. Any suggestions?

The fact you could not get into the router but networking works tells me the router is defective. Switch side is working but the rest is not.

Sorry Quin but it looks like its time to replace it. If still under warranty you could RMA it and get a replacement. It's defective.

Ok thanks I am going to call them today (the funny thing is that this is the 2nd time I have returned the router for a similar type problem). The last time I tried to upgrade the firmware and the router died :(
Thanks thought much appreciated.
