Same LAN Laptops Disconnected And Cannot Regain Connection?
Aug 26, 2011
I have a small network, about 35 computers.There is 20 LAN PC computers (they use dns, active directory, dhcp), and there is 10 laptops. They connect on same D-Link wireless router( radius server authentication).After most of laptops is operational(connected on wireless router and on domain ), same two laptops always disconnect, and they can't regain connection . All laptops also get their ip addresses through dhcp.I tried all kind of wireless router configuration, I don't think it is dhcp or dns server problem, remote access policy is also very simple
Someone tricked me by sending false email and gained control of my email address. I tried to log on and change my password but I cannot. How can I regain control. I am not experienced with computers. I would also like to learn more about computer basics to start.
I'm running Windows Vista on an ACER Aspire M1610 with a connectivity issue. I was running a static IP address before the connectivity issues. I tried overriding this issue by manually inputting an IP address. I found the IP address the router uses since I currently have multiple computers connected to the same router. However only one computer only have the connectivity issues. The cmd prompt reveals in ipconfig that my IP address as 169.254.14.118, started having problems when a hardware froze my PC and had to reboot it. i uninstalled it, resetted my router and modem, and still have connectivity issues. How do I regain connectivity?
Is it possible to regain the PSK from the security tab from a 5500 controller in clear text?I need to check the current used password without resetting it, but I fail to find the password in the configuration (CLI & web interface)Obviously I do have admin access to my controller.
I have 2 Laptops connected wirelessly, 1 Vista, the other Windows 7. The Vista laptop seems to be dropping the connection,when I look at 'Network & Sharing Centre on the Vista laptop, it's telling me signal strength excellent but with a red cross indicating there is a break between me and the internet. HOWEVER, the windows 7 laptop (on it now) is working perfectly OK!!
I just installed the free vpn client spotflux. The connection works fine, but after I disable the vpn again windows 7 seems to not use my "normal" ethernet connection anymore. I'm pretty sure that it will use that connection if I deinstall spotflux again but how to configure windows to use the normal connection when the vpn is not connected?I've attached a screenshot of the LAN connection settings and the priority list - but still it doesnt seem to work. What am I doing wrong?

We recently acquired an internet connection. Connecting via LAN works fine for me but not to my room mates. We're all using Windows 7. Windows troubleshoot it and says "Local Area Connection doesn't have a valid IP configuration" on their laptops. What should we do?
my computer is a laptop and its about 3 years old. Ive been experiancing problems with my internet connection...It seems that it is fluctuating between local and internet to just local every 5 minutes or less. Usually I fix problems with my software no problem this time
I have brought a broadband connection from a local ISP called YouBroadband. (I am from India, if you are wondering.) For the first month of my plan, I was having internet connection without any issues. But since 2nd month, I am experiencing a very strange problem. When I turn on my PC and connect to internet by entering my password, I do so without any problem. But after a few mnutes of connectivity, I loose my connection. Even stranger is the fact my Windows 7 Ultimate edition does not recognise this. It still shows connected sign in the notification area. But I am not able browse any more using any browser. to solve the problem, I start network troubleshooting, which in a few seconds shows, resetting 'Local Area Connection 2' and then I am able to log in again. At times this solution also doesn't work. All i can do at that time is shut down my PC, wait a few minutes and restart again. To my extreme dismay, this keeps happening over and over again. I connect, get disconnected, reconnect and again disconnect. This is terribly disturbing and annoying.
I have searched on Google with no success. I tried changing DNS server settings and put Google open DNS address as my preferred DNS server but that didn't solve the problem too.( I received this tip from a friend of mine.) Here's what I get when I type ipconfig/all in Command prompt-Windows IP Configuration[CODE]
I have 2 older xp pro tough books that connect to my domain via a pair of versa vx 400 access points. automobile technicians use these computers to communicate with cars via a separate wireless card and WiFi device (SPX MVXI) that broadcasts a wireless signal.they always connect just fine to the network but sometimes they drop there connection and don't rejoin which screws up my scheduled tasks (nightly upload). They will reacquire the connection every time if i select it again manually in the windows wireless config.here is what I have done so far
1. set up exclusion range in DHCP distribution on my DC
2. set the laptops up with static IP's within the exclusion range.
3. configured the laptops to auto connect to the network even when its not broadcasting
4. set the access points on channel 7, and the devices on 1 and 11.
I have done a lot of research on this issue, a rep from versa told me that Intel proset wireless isn't very compatible with there product which i this is BS since it does the same with with the netgear WiFi PC cards.
Me and my girlfriend moved into our new flat in September and since then we've been sharing my laptop as her laptop refuses to connect to our Wi-Fi, we are with Virgin Media and I have had literally no connection problems whatsoever but hers gives us various errors like 'No Internet Access' 'Local Connection Only' and sometimes it will connect for about 4 minutes and then just disconnects again, the only Anti-Virus she has running is AVG. It has also happened with friends who have brought there laptops over.
I have a US Robotics 5462 router and a D-Link DCM-202 cable modem on Comcast. I've had this router for years and initially configured it for wireless access using a Windows XP system (this router requires you to configure it via Ethernet and 192.168.2.1). That computer stopped working last year, so I got a new computer running Windows 7.When I first got this new PC, I could not connect to my router via Ethernet (just like I can't now), but I was still able to connect to the wireless network I had previously set up, so I was satisfied.
A year went by, and last week I was suddenly unable to access my wireless network, so I did a factory reset on the router, erasing my previously configured wireless network and requiring me to connect the router to my computer via Ethernet to reconfigure the router. I tried to do this, but despite all of the correct LEDs being lit on the router, I could not access 192.168.2.1. A little poking around on my control panel revealed that my LAN was being labeled as an "Unidentified Network" and there was "No Internet Access." I tried to make it a private network, but that didn't fix the issue.
I searched around for a while and read some advice to try running ipconfig. When I did that, I saw "Media Disconnected" for my LAN adapter. I've tried a few of the possible solutions already with no luck. With the same computer and the same Ethernet cable directly connected to my modem instead of through the router, I *CAN* get online. That's how I'm connected right now. Also, I have no problem accessing any wi-fi networks.
I have been searching forums for the last 2 hours and trying to figure out how to make this work. I tried to release/renew and it told me it couldn't and got the media disconnected message. I tried the TCP/IP and Winsock renew and that didn't work either. My internet was working OK and then all the sudden it stopped working. [code]
I have three laptops (running ubuntu with different kernel versions) with wireless adapter Intel Corporation PRO/Wireless 3945 ABG. Laptop A ----- Laptop B ----- Laptop CI created an adhoc connection in laptop A with: Essid: 'ad_hoc', IP address: 10.42.43.1, Subnet: 255.255.255.0, Gateway: 0.0.0.0, Now the laptops B and C can see the wireless connection 'ad_hoc' and I can connect to them after setting IP 10.42.43.1 and 10.42.43.2 respectively. So, I created the adhoc connection between 3 laptops. Now, I wanted to check the bandwidth between the different paths. The tool iperf was what I used for TCP bandwidth calculation. The bandwidth between A and B was around 4.5 Mbps , between A and C was around 4.0 Mbps but the bandwidth between B and C (B being server) was 677 kbps whereas C being server was 3.99. I don't understand how can the bandwidth drop so high when B was made the server. The system adapters are identical.
I have a belkin wireless router/modem running our home network. We connect using 3 android devices, a wii and wireless printer with no problems. However, when connecting using either a windows 7 or windows XP laptop the internet connection is lost after a couple of minutes. I can't work out the cause of the problem but resetting the router gives a couple of minutes of browsing before it goes again. I have tried using static IP addresses for the laptops but this hasn't worked, furthermore I have tried a winsch reset.
Is there a way for me to connect my desktop PC to my laptop, & use the laptops EDGE/GPRS modem in the PCMIA slot of the laptop to access the Internet? I also have a wireless router that is not being used for anything, however, I use the laptop to get online, & I'd like to share that connection with my desktop at home.
I had to reboot my Dir 655 because my 2 wireless laptops wouldn't connect to the internet. Once I reset all of my static IP settings in the dlink admin tool the wireless laptops work fine. The problem now is that I can't connect to the internet on the computer that is hard wired into the router. I recall once before having to adjust the TCP/IP settings in the Network settings, but don't remember exactly what it was the I had to do.
I have battling this issue since I bought this router, at least 2 years.

DIR-615 PC XP Wired 2 Acer laptops Vista wireless All DHCP reserved Security using wpa_psk
Not sure what other router info you need. All are connected to the internet, but can't see each other on the LAN. We can see each other from time to time. Sharing is allowed. Passwords are shared. I can power off the router and the network will be fine for about a day, then gone again. Workgroups are the same.
I have a laptop - Lenovo E43 in which i tried to connect with wifi, when wireless nework connection is opened, it is showing No wireless networks were found in range. and when IPCONFIGured, Media state...:Media disconnected is displaying under the Ethernet adapter Wireless Network connection.
I just installed nVidia Nforce drivers for my Asus 750i motherboard, I show I have internet connection, however I can not get windows to pull up a site. TRIED everything reset modem, router, checked all settings. When I pull up the networking system information, it states connection status: disconnected via the Nvdia controll panel. Reset everything back to factory defaults still nothing....IT was working, I intalled I tunes, and then it stopped....I uninstalled Bonjour thinking that it might be the issue....nothing
I leave on one of my computers on all the time, an Acer desktop with Windows XP. I also have two laptops. I have Verizon DSL and a linksy wireless G router. When we have a power outage the Acer desk top loses it's internet connection. Trying to reconnect the connection takes hours. Even when we finally get it back we have no idea how we did it. The laptops which of course were off have no problem.
I have two laptops which connect to the router via wireless. This router is wired to the modem. I can connect each laptop to the router then make an internet connection. This works fine. But if one laptop is connected to the internet, then the other cannot. I have to disconnect the first laptop then reconnect with the second.
I have had this scenario working in the past and can't remember what I have to do to enable both laptops to use the internet connection at the same time.
I have a 5520 ASA running 8.2(1) and ASDM 6.2(1). The ASA has been running for 223 days without issue. Today it stopped showing real time status on the Device Dashboard from within ASDM. All of the graphs state "Lost connection to Firewall."I try to manually reconnect but it will not. I have tried on a couple different computers and cannot get the monitoring connection to work.It is a very busy firewall and I will have to schedule for a restart (which I was thinking of doing) even though I do not see a memory issue as per snip below. I don't want to restart unless it is the best option.
Recently our ACS loss connection to AD. Notice following error message (collect from show tech):
Dec 9 00:05:31 OasPrp-Lvl07-ACS01 adclient[24514]: INFO <bg:ageBindings> base. bind.healing Lost connection to myhqkul990003s.simedarbygroup.com. Running in di sconnected mode: KDC refused skey: Preauthentication failed
[Code]....
However we manage to restore the connection by reset password of the AD account that used in establish connection between AD and ACS.
I have a Cisco 1811W that after several years in service suddenly stopped allowing any wireless connection to laptops on the domain. It allows hard wired connections and devices that are just using the wireless hot spot like iPads and Iphones but not devices on the domain. These same laptops connect wirelessly without issue at our other facilities which use the same hardware.
Here is the config file of the router in question...

I want to share PC internet (PPPOE connection) on my linksys wireless router (E3000)Problem : When i directly connect internet wire in router, pppoe connection frequently gets disconnected. So what i wanted was to share my pc internet on router.I have two lan card on windows 7 installed PC, 1st lan card is connected to internet cable and i can access internet on pc, second lancard is connected to wireless router. So basically what i want is to share pc internet ( PPPOE ) on wireless router through DHCP connection type.
I just got a new modem with built in router. and for the first few days i had my internet running pretty perfectly until recently when i just keep getting disconnected from it and then reconnected. i try to troubleshoot; it says that i DONT have a fixed DNS. i am pretty bad at networking.
