My parents Windows 7 PC has suddenly stopped being able to connect to the Internet. Using the "Diagnose problem" feature in the Manage Network Interfaces panel results in a message claiming that it cannot reach the DNS server and that the connection needs to be reset. Doing so has no effect. It is connected to a DSL router via an ethernet cable.The NIC is set to dynamically receive its IP and DNS settings via DHCP which it obtains from the DSL router. Executing ipconfig from a DOS prompt shows that this is occurring as expected, with an assigned IP of 192.168.2.10. The gateway and dns are set to the IP address of the router, which is 192.168.2.1. Note that I can't even ping the router at 192.168.2.1.I also tried static settings in the available range and tried using open DNS IP addresses.
They also have a laptop which connects to the same router wirelessly using DHCP and it is working fine. Using this laptop, I can log into the router and see both it and the problem PC in the list of connected devices, each with the dynamically assigned IP addresses as seen using ipconfig on each. Unplugging the ethernet cable shows the connection status changing in the list of connected devices in the router. From the laptop, I can ping the router and running ipconfig shows that it obtains the same gateway and dns as the PC and the next available IP - 12188.8.131.52.So this leads me to believe the following:
1- The router, NIC and cat 5 ethernet cable are working fine at the hardware level.
2- The DNS settings in the router are fine, as the laptop works
Perhaps coincidentally, the same day it stopped working they received one of those bogus "This is Microsoft calling" calls claiming their PC was infected, but they had heard of the scam and hung up. Naturally, I started suspecting a virus, but a full system scan using McAffee produced nothing. If it was a DNS changing virus, would I not still be able to ping the router using the IP address?
A Windows Server 2008 r2 with 2 internet ports. One (IP: 10.0.96.132) connected to company intranet and one (192.168.10.1) as DHCP server connect to several PCs (192.168.10.**) through a switch.The problem is the PCs (192.168.10.**) can ping the DHCP server (192.168.10.1) , while DHCP server (192.168.10.1) can not ping (192.168.10.**).How to configure the server so that all these PCs can access the intranet?
I have more than 10 PC om my Workgroup, using DHCP on network, but I have one PC alwaws got wrong IP (auto from dhcp), and can't connect even using static IP (status connect, but can't ping to gateway and other IP)Here "ipconfig /all" on one of PC that work. [code]
My old office uses Cisco 861 as a VPN router, with the WAN side setup to receive a dynamic IP assigned by Time Warner cable. Now we switched to a new office, with TowerStream which provide 4G SLA'ed 10Mbit service with static IP, and I get a Cat 5 ethernet down from it.
So all I did, was to go my "interface FastEthernet4", and typed ip address 184.108.40.206 255.255.255.252.Changed speed to "speed 100" and "full-duplex" (as instructed by the ISP).
I also did "ip default-gateway 220.127.116.11", which is the default gate way assigned by the ISP.I also typed "ip name-server 18.104.22.168" to setup the new DNS, am I doing anything wrong? I can't even use the router to ping google, but if I connect the laptop directly to the outside line, then it works, so I know the outside line is good.
Why can't I connect to the internet? I wasted several hours already trying everything in my book to trouble shoot a supposedly very simple configuration change. Do I need to change something related to NAT when changing to Static IP? My NAT was working just fine before when under DHCP.
The below is my full config (some IPs changed to preserve anonymity):
============================================= Building configuration... Current configuration : 16628 bytes ! version 12.4 no service pad service tcp-keepalives-in service tcp-keepalives-out
I connects to the wireless box and has full signal but an exclamation mark is present.I have run some tests and the IPv4 and IPv6 say they have no internet access.I also run a full test and everything passed except the ping test which failed and it said: no response:default gateway response: dhcp server it suggested disabling security firewall but i'm not sure if that's the correct thing to do or even how to do that!
I need another set of eyes on my config. I am trying to set up my router for a basic connection for the time being. I set my gig 0/0 port to dhcp I see traffic being sent and recieved but I can not ping 22.214.171.124. I am connected to a basic comcast modem from 0/0 I have also tried setting gig 0/0 to 100 full. I do have IP routing enabled. I believe I have my acl's configured correctly. I am wondering at this point if I need a static block of IP's from comcast.
"In the past I have noticed if I have one of my rigs running NAT and DHCP that my ping response times are lower compared to my router DGL-4300, when playing games. Is this due to the PC hardware being superior or is it a software/firmware thing?
Or is there a router out there that will perform better ping response time wise/ lag than my DGL-4300?"
Is this due to hardware or is it software/firmware? My NAT and DHCP box was a windows server 2003 configured with just those roles and my pings were in the 20-30 and I could host/join games no problem and no lag, but when I play through the Dlink DGL-4300 my pings would be 70-90 and some games I had lag issues and host/ join issues, sometimes it would work sometimes not.
I have a PIX 515E that I want to use to as a border between my internet connection and my Cisco AIR1131AG. I have configured the PIX to have the outside interface as a dhcp client which gets its dynamic IP address from the cable modem. the AP is connected to the E1 inside interface. Now I could see the E1 interface from the arp table from the AP but I cannot ping it. From the firewall I don't see the ARP table from the firewall. and i cannot ping the AP. what is wrong with the configuration? side note, i am able to connect to the AIR1131AG from my laptop I was not able to retrieve an IP address.

I have a laptop that works perfectly fine when plugged into a network cable, but the wifi refuses to work. It pulls an ip, and everything looks good when I run ipconfig/all, but it can't even ping the router. All other computers on the network are working fine. I've flushed dns, set static IP and DNS, uninstalled/reinstall device, updated drivers, bios, and firmware, and even created a backup image of the computer and reloaded the os using the recovery partition. The event log doesn't tell me anything, and there are no flags in the device manager. I'm at a complete and total loss. I cannot figure this one out.The laptop is a Compaq Presario CQ50-142US. Vista 32bit OS. Everything was working perfectly fine before it got a virus. I ran through the standard procedures of AVG, Malwarebytes, TDSSKiller, and even resorted to Combofix, but somewhere along the line the wifi dropped off and will not come back.I even double checked the HOSTS file and IE proxy settings to ensure I wasn't crazy; although I know those should've affected the wired connect too.My last step is to either replace the wifi chip (which I don't think is the problem), or wipe it and load the os from scratch, but I don't have an oem disc since it has the recovery partition.
I reconnected my SB after letting it sit powered down for 6 minutes to lose all of its configuration and I was then able to get it to connect to Cox's provisioning site and was able to get online with it, had to then force my router to re-detect the connection and now it is also working.Last night my ISP had an outage, or something, and I was not able to connect for quite awhile, keep in mind that my modem was working all day yesterday.It came back up around 2:30 or 3 am last night but since I was rendering some footage in Sony Vegas I did not check to make sure everything was good. So I get on my computer this afternoon and find that I am not connected to the net and that I can not ping nor connect to my SB5101. Pings all say Request timed out.All of the lights that should be on are on: power, receive, send, online all green, activity solid amber, which is almost never solid usually flashing. So I power cycle it and my router and plug them back in but now the internet light on my router never turns green, just flashing/solid amber.I am able to connect to my router, a netgear WRG3500, through the gui interface just fine. So I connected directly to my surfboard and was still unable to pull an ip address or connect to the gui for it. All pings and address renews resulted in request times out or media disconnected messages.At this point it is looking like my SB has gone bad, but I do not see how that could possibly be. These things usually have downward slides into crappy brokeness, this was immediate without any problems for 2 years.I am connected atm with my old D-Link DCM 202 modem I had before this one, which does not want to talk with my router, not sure why.
I am having problem connecting to my work PC via VPN Cant ping and RDP. I sometimes need to log into my work PC to check out a problem. I connect via VPN and I can access servers (using Citrix and local intranet sites) that can only be accessed once connected to my work domain. So it looks like the VPN actually works fine.
But I cannot Remote Desktop Connection to it. I also tried to ping the PC using a command prompt. Using the command prompt, I ping MyWorkPC And I can see that it tries to ping MyWorkPC.domain.name.co.za. So it looks like it sees the MyWorkPC on the network. But all pings fail.
A work colleague tried to remote connects to MyWorkPC from his home PC and he can successfully connect. So I do believe that the work network and PC is setup correctly. I am running window 7 Ultimate SP1 (32bit) with a 3G dongle in a router. I also have Avast antivirus installed on my PC. I was not sure if the router or the antivirus was the issue so I tried:
1.Removing the 3G dongle and attach it to my USB port on my home PC directly. No luck 2.Some blogs said that the P2P or IM shield on Avast might be the problem so I disable it. No luck 3.Then I uninstalled Avast completely to see if it has any shield that might still block it. I restarted. No luck
In the office we have 3 printers (2 network 1 attached locally to my machine). I can ping all of the printers and no packets are dropped, however I cannot connect to them.I know the printers arent faulty because all of the other staff have no problems printing.I have tried re-installing drivers, disconnecting the printer and reconnecting it etc. and I just cant find what the problem is
I am trying to set up a lan to lan vpn access with 2 asa5505's but I cannot ping, traceroute or connect from either side. I can connect to both ASA 5505's from the internet, and connect to the internet FROM both 5505's, just not one to the other. I can ping the network GATEWAYS to the routers, just not the routers themselves.
Both of these machines have been configured for previous VPNs but that configuration has been removed.
I have two computers side by side 192.168.1.7 and 192.168.1.8 both running xp pro sp3. On 8 I can RDC to the 7, but on 7 I cannot RDC to 8. I can see port 3389 listening on both using netstat -a. But 7 just can't RDC connect to 8. 7 cannot ping 8 either. I have the firewall turned off on 8, I had tried allowing RDC 3389 earlier with the firewall but that didn't work either.I don't have any extra firewalls running.Life will be like perfect, if I can just RDC to 8.Both are on the same wired belkin wireless router, 4' from itl.I tried taking the no ping no rdc computer to work and it didn't work there either.
I got a trojan and removed most of it with Malware Bytes. My computer was still acting squirrely so I read that I needed to delete a ping file. I did and can no longer connect to the internet. It just sits and tries to acquire the IP address. I have reset my winsock and tried uninstalling and reinstalling my network drivers etc..
When I try to ping ipv6.xsnews.nl on either of my Windows 7 computers, it returns "Ping request could not find host". But when I do it on XP, it succeeds. I have tried putting the W7 PC in the DMZ, disabling the software firewall but it doesn't work.
What I think it involves is having ipv6 installed on each. I tried to duplicate the setup of both the XP and a W7 computer, installing the gogo6 tunnel. But apparently it's not setup on this computer because the ping result is the same as on the third computer which hasn't had ipv6 installed. s not setup on this computer because the ping result is the same as on the third computer which hasn
I can connect to the internet after 5mins or so after booting up but after that internet will not respond at all.i need to restart again my PC in order to connect again to the internet i somehow manage to bump with this solution using ping command.whenever i boot my pc i need to open this command and i can surf the internet without getting my connection lost just as long ping command is open.
OLD Dell computer running Windows XP Professional. Just ran a clean install and installed new drivers yesterday. After installing Service Pack 2, I began getting limited connectivity errors. Tried ipconfig/release and ipconfig/renew, but received the DHCP error.
Ran a diagnostics test and failed the Ping test. I'm using the university resident internet. Called the tech place and they said they're investigating their connections and networking thing on their end. Just in case though, I want to know if there's actually something wrong with my laptop rather than their equipment.

I have recently bought two 1800 cisco routers and have tried to connect them over wan serial link, but I am having problems when trying to access resources on the other side. I am a newbie to cisco and I wonder if the problem is with the configuration or the new routers or the serial link between the sites. Below is the show-running config results I have done on both routers; I can ping the serial interfaces from both sides and remotely, but I can't ping hosts or FE from other side.
So I have a client with an ASA 5520 running version 9.0 (was on 8.4) that I am trying to get either IPSec or SSL VPN configured on. I got everything setup and tried to connect. However, I couldn't connect to either. I fired up the real time monitoring and didn't see any syslog messages referring to a VPN build up. I also enabled SSH/Telnet on the outside interface and cannot connect to the ASA outside interface. I can ping the outside interface and can ping the internet from the ASA. I did set up a test ACL on the ASA and ran packet tracer on it and the results came back fine.
There is an IPS in the ASA as well, but I disabled the ACL for that and still am having these issues. Part of me wonders if the ISP has something set up to block inbound traffic. This should be a business class connection.
I have a computer on a school network, i recently set up a WDS server to make rebuilding computers allot easier and faster. I created an image for a Inspiron Desktop 560ST but when i tried to redeploy the image back on the exact same computer while connecting to WDS deployment service i get this error.
<Installing windows>WdsClient: An error Occured while obtaining an IP address from the DHCP server. check to ensure that there is an operational DHCP server on this network segment.
Our default IP is not a 169.xxx.xxx.xxx it is 172.xxx.xxx.xxx so thats obviously not right, and then I try typing ipconfig /renew and it waits a super long time and then i get Windows IP Configuration:An Error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out.An error occurred while releasing interface LoopBack Pseudo-Interface 1 : The system can not find the file specified. This computer is part of a lab of about 25 computer and every other computer has no problems, even if i take the network cable out of this computer and plug it into the computer right next to it(I'm take it right from one computer to another, i'm not touching the switch end) the computer right next to it is fine. So its not the switch or the cable.
My Windows xp computer can't connect to the DHCP server correctly and thus can't connect to the internet. It is connected through an Ethernet cable to a wireless router. All other computers on the same network connect fine to the router, both wired and wireless.This all started after I left my computer alone for a few hours and came back with it not coming out of idle. After shutting it off and turning it back on, it would not connect to the DHCP server.It assigned me the autoconfig address 169.254.189.73 because it couldn't connect to the DHCP server. I even tried a static IP but even that wouldn't fix it. I have tried the same ethernet cable in another computer and it worked fine so I know that it is because of my computer.I have tried renewing and releasing the connection using ipconfig in the command prompt but that did nothing. The settings are all the same as the other computers running through the same router. I have tried shutting down all the other computers and reconnecting the trouble one but again still nothing.The last thing I'm not sure about is the network adapter driver. I have reinstalled it but I'm not sure if the driver is correct. I have an NVIDEA nforce 10/100 Mbps Ethernet adapter. I attempted to reinstall but I'm not sure I selected the correct generation when I downloaded the driver installer. My computer says nothing about the generation of the adapter so I just chose the newest generation. My adapter is integrated in the motherboard.
My XP laptops cannot connect to my TEW-639GR router over wifi. I get the "Limited or No Connectivity Message". The same 2 XP laptops can connect if they are wired without problems.My Ubuntu computer can connect to wifi and wired without problem."Limited or No Connectivity" usually means a DHCP problem in XP. I have DHCP turned on on my router.This problem did not immediately start when I first set up the TEW-639GR. It happened infrequently on my XP laptops initially for about 2 months but now it happens all the time.

I have set up three E4200 routers as wireless access points on our network. They each have a static ip and the same subnet mask and gateway that our pcs have. They also have a local address that I can connect to if wired straight into them.
I cannot ping or remote admin into any of them and I have enabled all the options to do so. The routers seem to work fine as WAPs, providing internet and network access.
I have a need to Remote Desktop connect to company’s employees for support then they are abroad and using Cisco AnyConnect client.Cisco AnyConnect client connection works fine, clients can reach company’s inside network without problems, but I cannot make revers connection, I cannot Remote Desktop connect or ping VPN clients from companies inside network. I cannot ping clients from ASA too.I am using ASA 5520, Cisco Adaptive Security Appliance Software Version 8.4(3) Device Manager Version 6.4(7), and Cisco AnyConnect VPN Client 2.2.0133.
