Random Disconnection from Internet

Greetings.

I've been having trouble the last couple of months, but it has been stuff I could live with. Now it starts to get really annoying.
- Every once in a while, my computer will disconnect from the internet and network. I try to reconnect to the network, but as soon as I press connect, it gives me a message that says it cannot establish a connection to the network. This happens for 30 seconds in a row before it finally works fine again. This occurs in spikes every 10 minutes to 6 hours in spikes of 2-4 times.

I have a suspection that this might be caused by my wireless network card, as I have 2 other computers on the same network, both using wireless network cards, that can connect just fine. I tried finding and downloading drivers for my network card, but as I'm running Vista 64bit I wasn't able to find any - only for 32bit!

I have:
802.11n Wireless PCI Express Card LAN Adapter
Intel® 82567V-2 Gigabit Network Connection

Also I'm running Vista 64bit, if you didn't notice! :)
And don't hesitate to ask, if you need any kind of information about my specs or details about thing's I've done or things I need to try.

I hope you can help me sort out this problem, 'cause it is really starting to drive me nuts.
Thanks in advance,
Rasmus

as I have 2 other computers on the same network, both using wireless network cards, that can connect just fine

when you get the disconnect - the other machines work fine on wireless - correct

can you post make and models of routers/modems/PC etc

I tried finding and downloading drivers for my network card, but as I'm running Vista 64bit I wasn't able to find any - only for 32bit!

Did the wireless card come with the PC - did you try the PC manufacturers website for drivers

can you do the following tests - ipconfig and two ping
1) when connected all OK
2) when disconnected - make sure you labell which is which


{ipconfig /all}
We would like to see the results from ipconfig /all

-> Start > run {search bar in Vista} > cmd > ipconfig /all
post back the results here


TWO Methods to do that - if you cannot access the internet with PC, then use method 2 to copy onto a machine that can access the internet and post results here

Method ONE -------------------------------------------------------------
start > run {search bar in Vista} > cmd > ipconfig /all

rightclick in the box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Method TWO -------------------------------------------------------------

Start> Run {search bar in Vista}> CMD to open a DOS window and type:

IPCONFIG /ALL >C:\RESULT.TXT

Open C:\RESULT.TXT with Notepad and copy/paste the entire results here.

----------------------------------------------------------------------------

{Ping Tests}
Start> Run {search bar in Vista}> CMD to open a DOS window and type:

Ping google.com
Post back the results

rightclick in the box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Ping 209.191.93.53
post back results

Hello Etaf,
I'll reply as well as I can - I know it's been some time since your reply, but I've had some difficulties reaching the topic.

First of all, I did search the manufactorer's website, where I would only find drivers for Vista 32-bit and Windows XP.
Secondly, my stationary computers are wired, but I have a laptop that can run on the network, no problem.

WITH CONNECTION:

As I'm using a Danish OS, I'll try and translate as well as I can:
The Ipconfig /all:


Hostname: Oppe
Nodetype: Hybrid
IP-routing activated: No
WINS-Proxy activated: No

Wireless LAN-card Wireless network connection:
Media condition: disconnected
Description: 802.11n Wireless PCI express Card LAN Adapter
Physical Address: 00-22-5F-75-DB-CA
DHCP activated: Yes
Automatic Configuration activated: Yes

Ethernet-Network Card LAN-Connection:
Media condition: disconnected
Description: Intel(R) 82567V-2 Gigabit Network Connection
Physical Address: 00-24-8C-5C-AE-89
DHCP Activated: Yes
Automatic configuration activated: Yes

Tunnel-Network Card LAN-Connection:
Media condition: Disconnected
Description: isatap.{25610CEF-4ED6-461F-AFA0-26C2DA3059DE}
Physical Address: 00-00-00-00-00-00-00-E0
DHCP activated: No
Automatic Configuration activated: Yes

Ping results:
Google.com:
Ping statistics for 74.125.45.100
Packing: Sent: 4. Recieved: 4. Lost: 0.
Calculated time for circulation in milliseconds:
Minimum: 141ms, Maximum: 152ms, Average: 144ms

For Ping 209.191.93.53 it was the exact same results with exception of the milliseconds to reach the IP.

I have a suspection that it might be the network card's communication with the router, as I have lately recieved a message, saying that the capacity of the network card doesn't meet the requirements of the network.

I will post a report of the same information when disconnected ASAP!
Thanks in advance,
Rasmus.

the ipconfig /all does not look right - everything is disconnected

another ping to do is the IP address you get from ipconfig /all for the default gateway

I just did a ipconfig /all while being disconnected from the network, no changes to it from the one above. The ping resulted in perfect connection while online with the network atleast.

I just did a ipconfig /all while being disconnected from the network, no changes to it from the one above. The ping resulted in perfect connection while online with the network atleast.


You have a disconnected ipconfig /all but you are able to ping and get a reply

.... mmmmmmm ..... confused now

I'm not really sure, what you mean, but I'll try and answer with what I think you want.
Two computers wired to the Modem, a laptop working fine on wireless and one (the one with the problem) on wireless with the router.
Suddenly, bam - network connection on the wireless stationary computer goes off. I can still see the network when trying to search for networks, but I can't connect to it for half a minute. Then I can connect and everything is working fine until next disconnect (usually happens every 40 minutes, if not in spikes of 5-10 now).

Also I recieved a message yesterday, when searching for networks while being disconnected. On my network it said:
'This network card's memory capacity does not match the network's requirements.'

If you meant something else, please endepth it to me :)

I'm getting more confused, thanks for your patience,

Two computers wired to the Modem, a laptop working fine on wireless and one (the one with the problem) on wireless with the router.


Can you provide the make and model of the Modem
Also provide make an model of the router

Confirm configuration
Two PCs connected to the modem via a cable
Two Laptops connected by Wireless (which is via the router )
One laptop connected with wireless gets intermittent disconnects
All other 3 machines PC / Laptops both cable and wireless continue to work ok

Is that correct – if not please correct
Also
Sounds like you actually have two routers, one for cable. Which is a modem/router and one router used for wireless.
Is that correct
If not please correct

On the machine which keeps disconnected
When its all connected and working fine on the wireless
I would like to see the ipconfig /all and the three pings results

Ipconfig /all
Ping the IP address from ipconfig for the default gateway – should be something like 192.168.0.1
Ping google.com
Ping 209.191.93.53

Now when the machine disconnects
I would like to see those results repeated for the disconnect status
