Internet Disconnects randomly

[gstratto]

Im back, and i've had sleep! So i have checked everything I can about this issue.

Internet disconnects a lot, I get the yellow "Searching for connection" icon down the bottom right on my network icon in the system toolbar. The Dsl light goes out on my modem, Siemens Speedstream 4200, and im getting some strange error messages in event viewer.

I've checked my memory settings in Task manager and I have plenty.

Im running Windows 7 Build 7600 with 4gb of ram.
I am the main computer on my home network and another family member has a Windows Vista 32bit PC that is wired to mine on the lan and shared through ICS on my machine.

Any help would be awesome, if u need me to post any logs at all i am prepared to put them up.

Thanks in advance,
Gstratto.

Looks like an ISP issue, give them a call and see if there are outages in your area.

I would say this may be the case, had it not been running perfectly on Windows XP pro, a few days ago before I installed Windows 7 Ultimate.

I have phoned my ISP and there has been no outages in my area, I even got them to do a line test and they say its all fine from thier end.

I can only conclude, from reading other forums and seeing that many users are having similar, if not the same problems, that it is Windows 7 Network Related.

Although I did find this just now, looks like a DHCP lease error.

Any ideas?

In fact ive been through event viewer and these are the events that happen every time the internet resets and i lose all my connections.

1. Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded.

2. Name resolution for the name www.msftncsi.com timed out after none of the configured DNS servers responded.

3. The DNS proxy agent was unable to allocate 0 bytes of memory. This may indicate that the system is low on virtual memory, or that the memory manager has encountered an internal error.

4. The browser has forced an election on network \Device\NetBT_Tcpip_{03B8A046-1B0E-4F98-A347-23D2E40DD9A0} because a master browser was stopped.

5. DHCPv4 client service is stopped. ShutDown Flag value is 1

6. The ICS_IPV6 failed to configure IPv6 stack.

7. The DHCP allocator has disabled itself on IP address 169.254.53.179, since the IP address is outside the 192.168.137.0/255.255.255.0 scope from which addresses are being allocated to DHCP clients. To enable the DHCP allocator on this IP address, change the scope to include the IP address, or change the IP address to fall within the scope.

hope this helps?

Whats your virtual memory set too? should be 1.5 times your physical memory, Its under Control panel>system and security>system>advance system settings on left > advanced tab> performance settings> advanced, there youll see virtual memory, I was disconnecting with RC build but when i updated my drivers and changed this had no disco's, so one or the other fixed mine.

 

[gstratto]

Its at 4094

 

[Urbwolf]

Thats your physical memory im talking about virtual memory, Follow the steps to see what it is set at

First question for me with all that you have done, would be.
1. open all connections from the outside box.--check for tightness on connections.
2. ( I have in the past - removed ea wire and polished with fine emory cloth. helps make a good contact.)
3. once every connection to your MODEM is (in your opinion EXCELLENT.)
4. find an replace FILTERS.. a filter can go bad at any time...
(personal feelings..Win7 is much more sceptible to noise than XP or Vista.)
5. In your system do you have the ability to run a noise ratio check.

Noise is a killer -

I ran all new line from the ISP connection to my MODEM, and speed increased 1.50 x and disconnects stopped all to gether.

 

[gstratto]

Same currently 4096

 

[Urbwolf]

You have 4gb of ram change your virtual memory to custom, initial size 9000 and max 12000 and see if that helps

Good point i will clean up all my connections and get back to you a bit later. Thanks.

What do you mean by Filters? If you mean the filter the isp puts on line you cant remove those (well can but can be fined by law) or do you mean the Splitter? Your internet connection should be off your first drop with your cable going straight to modem with no more splitters in-between. If you have already called your cable company and they can see no disturbance in noise from there end to your modem i doubt that is the problem, usually they have your internet running at the highest db in line strength because of it nature.

 

[gstratto]

Done will reset and see how it goes till morning.
Thankyou for all the help people.
Will report back if its crashed while im sleepin.
Cheers,

I think he means the line filter also available as a splitter(if you have a phone coming off same port) that you plug into the phone socket so it cancels out noise from house phones etc

 

[Urbwolf]

Ahh a dsl line sorry thought you were talking cable connection.

Disable IPV6. Could be killing your router.

 

[gstratto]

I disabled IPv6 on both lan connections earlier, but it still disconnected after that. seems to be going ok atm though.

 

[Urbwolf]

Did you change the virtual memory

 

[gstratto]

I did

Also I have woken up to find that my Machine has not Disconnected once through the night.

Usually its sitting on the login screen from recovered from a serious windows error.

So knock on wood, it looks to be fixed. I will post back in a few hours of gameplay and networking to conclude

Random DC today

Heres what the event viewer looks like.

I dont get it
DNS error tells me im out of Virtual memory, so We upped that.
System tells of a IPv6 error so we disable that.

and still the errors.

This is the Warning at 4:47:55
Name resolution for the name messenger.hotmail.com timed out after none of the configured DNS servers responded.

Im beginning to think that Windows 7 has more bugs than vista.

On top of this. IE keeps crashing and recovering tabs of sites that i am going to. I watch a movie or something through Mediaplayer and it crashes 10 mins through, getting a lot of application hangs and not responding errors on msn, MSoutlook 2007 and other programs.

Also the killer is it updates and reboots when it wants. right in the middle of stuff. Im sure this can be set to not auto reboot. but between the errors and the reboots.. i guess im hoping a update will actually fix the OS. Come to think of it.. all these problems started after the first or second lot of updates after original install.
