Above is a link to ethereal. It is an excellent tool to analyze the packets sent and received by your machine. It is very interesting to look at and extremely helpful to diagnosis of problems in general.
There is a slight learning curve for how to use it well. But if you are of the type that would be interested in this kind of thing, I trust you are also of the type that can use it well.
For instance, you can see all the traffic on your local lan and what your computers are saying to each other. You can see how your router calls out to your machines to ensure they are still on the network. Lots of other cool things.
You can see when you start up certain software that they are trying to "call home" which many people find they do not like at all.
Play around with it some and you may be glad you have a new tool at your disposal. You could use it to capture all packets sent and received, for many different purposes, from any specific adapter. Perhaps you want to see what your computers are doing while you away or while another is using? Alright, that's a little shady though, heh heh.
I have a peculiar issue where I would need to have "Network and Sharing Center" open to be able to see that my my laptop's wireless connection. I would see the signal bar and also see the dreaded red x.Even when I have it open, I can see it refreshing each second; like its losing connection and reestablishing.My internet connection is working and has no issues.

I'm having difficulty trying to get my new Windows 7 pc set up to share files across my existing home (wired) network which consists of 1 desktop pc running WinXP and 1 laptop running WinXP.I want the 'C' drive on each of the 3 computers to be shared. I've had the 2 Windows XP computers set up and working like this for several years without a problem but I can't seem to get the 'C' drive on the Windows 7 computer to do the same.All 3 computers have the same workgroup name and none of them require passwords to log on to Windows. There are no problems with the firewalls on any of the machines.On the Windows 7 PC when I right click on the 'C' drive and select the 'Sharing' tab, I have set this up to be shared and when I click on the 'Advanced Sharing' button there is a tick in the 'Share this folder' box, the 'Share name' is 'C'. If I then click on the 'Permissions' button, this shows a 'Group or user name' 'Everyone' and this group has Full Control, Change and Read boxes ticked. As far as I can see there is nothing more I can do.
However from my Windows XP computer, when I go to My Network Places and double click on the icon for the Windows 7 'C' drive, I get the message "\Computername is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.The network path was not found"I've subsequently set up a sub folder (of the Windows 7 'C' drive) for sharing by right clicking on the folder, choosing 'Share with' and then selecting 'Specific people'. I then set up a group called 'Everyone' with read/write permissions. Now I can navigate to this folder from my 2 WinXP computers.
My rig uses a Centrino Advanced-N 6230 wireless mini half-card. It reports the correct name except within the wireless network list. Instead of 6230 it reports 6320. I searched the registry to see if I could find the error, but nothing found. It's only a nuisance, and a minor one at that.
Unable to see home network computers in Windows Explorer Network screen.
I have a home network with 2 laptops and 1 desktop. The desktop I use as a "file server" in that all work done on the laptops is stored to the desktop. The desktop computer name is HAL. One laptop is fine and sees the network. The other just stopped seeing it; rebooted the laptop; rebooted HAL; did a number of refreshes without any luck. I opened EXCEL and found a worksheet that was listed that I knew was saved on HAL. Was able to open the file and when I tried the SAVE AS I could navigate through all of HAL just as normal. Went to Windows Explorer and still no HAL listed as a COMPUTER on the NETWORK. I have a internet connection so I know I am making it to the router at least. And when I check NETWORK AND SHARING CENTER it shows an active home network. The laptop is running Windows 7 Home Premium Service Pack 1 Build 7601.
This sounds really noobie of me but is it possible to improve local network transfer speed by adding a 2nd network card. I was planning to connect one exclusively for lan transfers and another one hooked to a separate wireless router.
Right now only a maximum of 3 users can stream SD videos off the PC before it gets a little choppy.
The pc in question runs on windows 7 and it's board has built in gigabit, I happen to have a spare gigabit card.
Home network with Wifi and ethernet. Using 3x Notebooks and 3x workstations. One of the workstations (W7 ultimate) keeps changing between Public and Home. When this happens, the internet connection dies. I cannot see other workstations either when on public network. Workstation using wifi. Does the same on cable. When it changes to Public, it disconnects from the internet and I cannot get to the router even though it has the workstation has an IP(DHCP or static). Default gateway and subnet is correct. TCP v4 is being used and nothing else is enabled.
Why is this happening? - I have tried DHCP as well as Static addresses - Reconfigured NIC(Netgear WG311T), uninstalled and reinstalled it. - Removed Wifi connection and re-added it. - Changed auth type, encryption type and keys to connection
Have I covered everything? The only thing different is that I installed a new router - Duo Plus 300wr. It cannot be the router because all the other notebooks connect to it wireless and so does my iPad, Android device and tablet...so it rules that out?
My problem is windows 7 hangs and freeze when access 2003 server Enterprise edition. This is not a small network, one of the biggest network.i have doubt on individual users on domain. before 2 months we had department wise users mean, for example Accounts@domainname.local. But after we created the individual users like john@domainname.local to all users. this is i believe the cause of problem. When we acess the server via the software it freezed for 5 seconds and then repeat to normal state. And after some time it hangs for 2 minutes.
I disabled my network adapter then restarted and now the adapter is no longer showing up in my network connections. How in the world do I get it back? I have looked at other options (like under the registry which was suggested on a couple of places). I have never seen this happen before. I even reinstalled my drivers and still nothing. How do I enable it again?
how do i keep microsft explorer from trying to surf and find other providers and stay on one instead of showing every provider it can connect too ant2twon@yahoo.com
Today, I managed to redecorate my bedroom; where my computer sat on top of a shaky, wooden desk. That desk is now gone, caput, and replaced by a much bigger, sturdier and prettier glass replacement.Before I dissasembled the computer to re-decorate, I was able to browse the internet at ease. There were no problems at all...However, after the new desk was setup - and all wires replaced in their correct slots, I find that I am unable to connect to the internet, or even the house's network! For the past year, I have been wired to the router using a RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC. It was plugged into an extension cord, in my room, into the Ethernet port in the back of my computer. Downstairs, it's twin was situated no less than 2 feet away from the router - plugged into the first port.Now, when I boot up the computer, the network notification presents the following message: "Unidentified Network. No network access", and sometimes presents a yellow ! next to it. So, I am reduced to typing on my mother's laptop - which has no problems connecting to the network.I am able to use the ipconfig /release command, but unable to use the /renew - it hangs in the command prompt, then tells me that the DHCP server cannot be located. The IP, beforehand, was reverted to 169.254.223.117 - before all of this, I was 192.168.0.5?
I have a linksys usb600n (v2) using the Windows 7 driver from linksys. It installs and is displayed correctly in Device Manger - BUT it doesn't appear in the Network and Sharing Center as an adapter. This same device and driver were previously working just fine in this system - but I rebuilt the OS (clean install) after testing a number of security products out.
The initial install went fine - no problems that I remember - just plug in the adapter and install the drivers obtained from Linksys (Ver 3.00.01.0). I tried the same thing on the re-build and it looks fine until I go into the Network Center and can't set up wireless networking since the adapter does not appear.
SIW shows TWO (2) linksys USB adapters under Hardware/Network Adapters, but does not show the network adapters in the Network Information section.
Installed Windows 7 on two home-network computers. Everything appeared to be good, including networking, but I could not access printers (linked through each computer) with the opposite computer. Windows update offered an update for the Broadcom 802.11n network adapter, but when I installed the update I completely lost the network.
I had to revert to the old driver in order to reastablish the network. But the printers still are not recognized. The network adapter on the secondary computer is a Linksys WMP300N. I did try turning the router off for ten seconds with the updated driver but that had no effect.
I want to add additional icons to the 'system32pnidui.dll' file. That's where you pick which icon you want to represent the active named network in the Network And Sharing Center. I did a search in this forum on 'network icons' but didn't find anything. Aside from all the permissions restrictions what app can be used and what kind(s) of files will work in W7? I have lots of .png images that I would like to use if they will work. Lenovo T500 W7 Pro-64 Current Updates.
New windows 7 Home Premium desktop that can print when the printer is directly connected but can't print when the printer is connected to an XP pro pc. It can see it but we're getting a "driver cannot be found on the network" flag.
Recently when I try and connect to the internet my wireless connection network says it is an unidentified network with no internet access. This never happened before.
Okay so I've installed windows and everything is working okay except i can't connect my laptop to my computer via LAN because it won't let me change it to a HOME NETWORK. It is just gets set to an unidentified Network. any possible suggestions?
Also I've look at removing this from the services but its not running it when i go under task manager, unless it somewhere else.
How to change network type to private network in networking and sharing centre with out showing UI to the user and it need to be done pro-grammatically.
(the bytes sent and received). It seems skype calls and watching in browser videos shoot them up into the billions after a few hours +. Upon googling around i am quite alarmed. Why did my network randomly change to "network 3"? A few weeks ago it just said 'network'?
I have 2 different laptops. both running Windows7 and connecting to the internet wirelessly. within a few days of each other they both began to display "Currently connected to: Unidentified network No network access" and they will not let me get on the internet. It is not my router becuase It shows the same thing no matter where I try to connect. I have tried my gym and a local restaurant that I have always had success connecting to before. Furthermore my WindowsXP desktop is directly connected and is connecting to the internet without any problems. My laptops are both running AVG for antivirus.
For boxing day, I bought myself a new Computer case, a Cooler Master HAF 932. After setting it up and booting my computer, without any problems, my Internet would not work.
I attached the Network & Sharing Centre screen to show you what it says. I've tried many things, switching cables, direct input from modem (I use a router), and all sorts of guides that have similar problems.
Windows did not show any network connections in the network connections window. I tried everything that I could find online but nothing worked. As a last resort I decided to reinstall the driver for my Intel 82566DC-2 Gigabit network connection. I uninstalled the old driver and then installed the latest drivers but now I get code 31 (cannot find the driver software) in device manager and the connection doesn't work.
5 month old Dell XPS 8500 Win 7 64 bit Pro as main computer connected by Wired Adapter, Upgraded Gateway 5632E also running Win 7 64 bit pro as second connected by Wireless. Both running Kapersky successfully. no network problems for 5 mo.
Both were successfully linked using homegroup. Had to take Gateway to a remote location to do a business demo. While there had to link to a local public WiFi. While connecting made mistake and left homegroup.
When Gateway returned to homebase a few days later it was fine, had no problems finding wireless but could not see or rejoin Dell machine homegroup. It would let me set up a new homegroup.
Went to Dell box and found 1) homegroup no longer existed, 2) router and network and wireless printing no longer found - Red X on the taskbar) even though internet was still working fine.
Took nearly a week of trying differernt fixes, on adapter- off adapter- different adapter reboot network, router, even updated router firmware (Yes I went through every ipconfig reset, renew, redecorate etc. I've used netsh functions to try to get evrything to reset. Changes services.msc settings per other posts. Finally in desperation, deleted every sub key in the registry related to network locational awareness and got the Dell to find the network, let me set it up as a "home" network and then even see the invitation to join the Gateway's homegroup.
Then I hit a wall- when I try to join- Win 7 says I can't join the homegroup because the network is not a "home network". Of course troubleshooting is useless and goes into an endless loop. Have searched in desperation for any way to make Win 7 return to a clean slate so it can sense that it really is on a home network without success. Applied the fix-it and hotpatch for when Win 7 gets stuck in public mode. No joy. Deleted the hide wizard subkey as suggested elsewhere. No Joy. Gut feeling says problem must lie in the NLA or peer networking somewhere but where?
Does anyone know of a method or set of steps (short of a clean reinstall of Win 7) to completely clear every thing the OS knows about my network and force it to acknowlege my network is a home network? Is there a registry hack that will clear the problem?
I know I could abandon the homegroup and do conventional file/print share but I am concerned that using that solution won't last as whatever is screwing up the homegroup could eventually screw regular sharing and then I'm back to reformating/reinstalling. I'm just about ready to join the Apple folks so I never have to work on Windows again.
I am using Windows 7, when I startup I get my network and a public network with no internet availiable. I only get internet access when I disable and then re-enable my network connection. I have tried to disable this public network permanently, but without success as the same problem occurs after reboot.
I just got finished building a new PC and the network is locked saying "unrecognized network/public network" and I cannot change it. I do not connect to the internet and I also do not get an IP address from my router (DHCP, the address given to the adapter is a 169.x.x.x address. This PC is sitting on a small workgroup here at my office. I have tried to disable the adapter and re-enable, I have reloaded drivers from the original CD. Here are some specs on the hardware and software.
Windows 7 professional x64 Asus P7P55D-E LX motherboard Intel I5 760 processor 8 Gb DDR3 1333 memory
No other software loaded at this time. This is a brand new build, after windows finished loading I loaded the drivers from the Asus CD provided for the motherboard.
I have a lan connection and when i connect it to my laptop, it tries to identify in the begining and then says "unidentified network, no network access", and when i ran up windows Diagnostics, it says "Local area connection does not have a valid IP configiration".
Additional information: * I dont have bonjour or anything to do with apple installed.*My firewall is off and i uninstalled macfee security.*Laptop model: Dell inspiron 1501.Iam really getting fed up with this, seeing that i have some really important documents i have to send via the internet and this problem happening suddenly?
