Internet connection stops working every few days

[IhateVISTA]

So, I'm on a comcast wireless setup. Then, one day, I am able to use IE and Firefox to access the web- but I can only hit on Google sites (I assume this is because I have Google desktop which I suppose acts as a tool) and no other sites will load. My signal is high and my computer is POSITIVE that my connection is fine. So, I shut down firewalls, disable programs, shut down windows defender, do a system restore and even call comcast and make them come out and replace my router. Once they replace it, I'm back online again! Full access. That was yesterday. Now, I'm plugged into my router because it's pulling the same ol' $#%^ again. I go through all the same things again. The only thing I can think is that my neighbor sharing my connection has something to do with it (although this doesn't make sense since we've been sharing for months and never had a problem till now), or some new bug is going around, or Vista is burping again.

If any of you guys have any clue what to do, I'd appreciate it as well. Take it from someone that's tried EVERYTHING.

Till then, I'm wired and still hate Vista.

I still suspect network sharing is the culprit. This article may have an answer if I could understand what they are saying: http://support.microsoft.com/kb/927168

They have horrible technical writers at microsoft. They assume I know what "receive side-scaling" is or even where to locate it.

Last night I lost all access to the internet. I am really thinking that it is a networking issue. My computer will work and then if someone else gets on on a different computer then I can't get on again. This is all theory as of now.

I have had cox out here over and over again.. We've replaced the modem, the line from the box to the puter, the line to the alley, and the line DOWN the alley. I truly believe this is just more of M$'s bedevilment. Not enough have this to make it worthwhile to fix it? I have trouble believing that also. More like they have figured out that the next version is more worthy of their time and trouble. Kind of like ME.. Heaven forbid that they fix it... or offer the poor suckers a copy of the next version in recompense. My internet connection still drops twice a day (and no.. I am not filesharing, and my vista is legal) However i am lucky. I can simply reboot my modem from the laptop and keep going. Now and then I get some crazy message about trying to find a wireless connection though... then i need to reboot.

Within the last 2 days my ie has decided it does not like to do files on my computer either. So I hope this does not mean you have more to look forward to. I am bed-bound and about ready to cry over this whole mess

IF you are using a router, and it is set to automatically assign IP
addresses, and doesn't have enough IPs allocated...and your machine loses
it's connection and another machine connects, you would not be able to
connect until the other machine disconnects.
That may or may not be the issue, but worth looking at.

I took some time to check for Microsoft support and to start my
Vaio and check for the "Internet Connection Sharing" service ...
which is not started (Inactive).

Well I also tried today to open multiple Explore...

Hummm, after about 50 explorers opened, I have the same
problem as with IE7 (quite normal if we consider that both
are similar). Once my vaio reaches about 990 Mb memory
(around 1 Gb), out of 2 Gb nothing else can be run on my
laptop.

I got a message on one of my try :
- Not enough available memory ... (Task manager shows
990 Mb used out of 2 Gb !).

Well, I will now close my explorer windows and stop again
my Vista for the next 2 months ...

The most likely root cause of your problem is that your internet connection just ran out of memory, and stops working. This can easily happen if you use P2P where you maintain thousand of connections. The problem is easy to fix. You can do any of these, or all of them (in increasing order of difficulty):
1. Reduce the number of connections. Don't use the queue to hold the next 100 items to download.
2. Configure your P2P client to limit the number of connections it maintains.
3. Reconfigure TCP/IP to allow more memory to be used.

The limitation might not be in your PC, it might as well be in your router, so (3) might apply to your router as well as your PC.

If you use equipment from for example Cisco, you will not have this kind of problems in your network, so then it will be in your PC.

I have certainly seen the problem originating from both the PC as well as a router.

Often, if this happens, the equipment has some kind of a timer that will reset the connections, and it will start to work again by itself, and after some time, again fail.

Good luck
