I have a server (Windows Server 2003) that randomly looses connection with the default gateway and anything on the outside. When this happens, the server cant ping the gateway (A Juniper SSG5 firewall/router) and the gateway cant ping the server. But the server still can ping anything else on the network and everything inside the network works fine with it. The most reliable remedy is to reboot the router. Rebooting the server or resetting the network card sometimes works. I have tried both onboard network cards and a separate PCI network card on the server. There are no router log entries that correspond to the problem. This server is used as a Terminal Server for a remote office and as a file server.
When I start a VPN-session my server looses internet access. The server is host for a few virtual machines and they have internet access.using 5505 and asa is version 8.4(2). [code]
I dont know why this keeps happening, It was a problem last summer and now its happening again. My modem looses connection and only a few lights are on. Im using comcast in the DC/Metro area and Im using a telephone modem.
I can connect to the internet via wireless just fine, and everything will be hunky-dory for a while. After a while, however (this varies anywhere from a day to a week), there will be a small hiccup on the connection, and then something fails in the Acquiring Network Address stage. My computers will get an IP, but they will not get the default gateway or DNS server.I have tried a plethora of fixes, from simple computer reboots to fiddling with all sorts of settings, and nothing works to reestablish the connection. My father has also tried fixing it, to no avail. I have to go and reset my router, which also interrupts TV service, because it is through AT&T U-Verse. Needless to say, this does not make other people in the household very happy, and I really shouldn't have to be resetting my router every couple of days like that. My PC uses a Netgear WG111v3 adapter and is Windows XP. My laptop has on-board Wifi and is Windows XP Professional.
Our company has a Cisco 1841 router which provides our connection to the outside world. We also have a windows server which provides our DHCP and DNS services. Our workstations which also get their lease from the server (using DHCP) do have a connection to the outside world.
when we connect a new computer or other device to the network we can only ping as far as the inside interface of the router. But when we assign the ip settings staticly we do get a connection, even if we configure it with the exact same ip as a lease it got a few seconds ago.
I have a wireless router which is connect to a DSL modem. Everything was working fine but now the wireless router looses connection often and if i remove the RJ45 check from my wireless router and plug it in after few minutes it works but again it looses connection.
My new RVS4000 (2.0.2.7) connects the WAN via PPoE with dynamic IP which is held at DynDNS and normally I see the RVS4000 via a router-to-router-VPN. That works fine so far, but every "some" days the router looses WAN connection (and with ist VPN). When this happens, last DynDNS-update is hours ago, so it didn`t reconnect. Looking on the routers site, the LAN is fully functional for clients that have got their DHCP-Information. New clients don`t get DHCP-Info (IP-address, DNS), both do not have internet access. The router`s WAN-summary shows, that it thinks to be "CONNECTED" but with empty WAN-IP and DNS entries. Klicking "DISCONNECT" and then "CONNECT" again solves the problem so far. The loss of connection is not the periodic break from the IPC, which is correctly identified and reconnected as configured. I wanted to trace the problem with the log, but there is also a bug. It stops logging at some time completely - neither email-log nor local log, so I never happend to be lucky to hit the point of loss of connection. Also the local log provides a first and next pages, but the next pages are always empty - not really useful.
I have a WES610N in my office connected to a E4200 @ the cable modem in the family room. ~30'.The connection is fine and works well when working.Connected to the WES610N I have:
-Polycom VOIP phone -HP Mediasmart Windows Home Server -Desktop -Multi-Function Laser Printer
I have two issues.
1) The Polycom does a random reboot that I have traced down to it loosing it's IP 2) The Windows Home Server looses it's IP requireing a hard reset.
I have enabled QOS for the polycom and that just worked with managing data. However both devices seem to loose their IP regularly. The desktop might also be having the issue but because it is Vista I suspect Vista is better equipped to deal with IP issues.
I recently started having trouble with my VPN clients loosing connection.I can create the conenction, work with it for a while, and then loose connectivity.Timing seems to be dependent on the activity over the connection.More activity, the conenction stops working sooner.
The cleint doesn't disconnect, I just can't access anything from the client.Disconnecting and reconnecting the client fixes the problem, temporarily depending on how much data I'm transferring.This works 90% of the time.The other 10% if I wait 30-45 minutes, and try again.. It works...with the same results...
It was originally isolated to a Win 2003 server that I was using as the client.It is now happening on my Win XP client as well.I'm using the AnyConnect client ver. 2.5.2014 with the VPN service on the UC520.Which I beleive, is similar to the ASA 5500 series VPN device.I am running ver 8.1.0 on the UC 520, and I can't remember if this started after upgrading to the new software.
Region : UnitedStates Model : TL-WR1043ND Hardware Version : V1 Firmware Version : 3.13.12 Build 120405 Rel.33996n ISP : AT&T
Every 5 to 7 days my router loses connection with WAN (ISP modem) but connection over LAN is fine. It seems that 1043ND tries to connect to DSL modem from AT&T by username and password (that does not exists) instead of doing Dynamic IP. I understand that AT&T modem is of type of PPPoE but there is not a password or user id and connection must be dynamic. Page 192.168.0.1/logininfo of modem complains that I was trying to login with incorrect user id password. Every time I have to
1- connect the modem directly to my computer so the modem resets.
2- I have to reset 1043ND to factory default, reboot, and connect cables back how they were, Then go to WAN page do a release and renew to get connected to WAN again.
i have a WUSBF54G that will connect to my router just fine. Right when the device is first plugged in there aren't any problems. I can ping my router, I can ping google.com. The browsers all work correctly, etc. But after a while, maybe 30 minutes (it varies) I lose the connection to the internet. I can still ping the router. I can ping other devices on my network. But I cannot ping any websites by DNS name or by IP address and any browser I use won't display any websites. I have other wired and wireless connections on this network that don't have any problems. I even unplugged this adapter and plugged it into a different computer and had similar results. The device is relatively new (maybe a month old, but only used a few times within that month, and the use that it did get is mostly from trying to troubleshoot this issue.) Both computers I have installed the device on are running Windows 7 Ultimate. Both computers have the latest drivers installed from this site:

I have a netopia 3000 router and I have checked to see if the problem could be caused by this router but there is nothing out of the ordinary there. All of my troubleshooting has been using the Win 7 "network and sharing center" to connect. I couldn't get the linksys connection tool to work and actually, I noticed after reading this forum that the linksys wifi connection tool doesn't work with win 7 after all so I don't think using the built in win 7 wifi tools would cause the issue. Also, just to clarify, in an attempt to resolve the issue I have tried dynamically assigning an IP address for this connection and also a static IP address. Either method seemed to yield no results. It is a frustrating problem to say the least. I don't want to believe that the adaptor is faulty. As I said it is relatively new. Also, as I mentioned, when I first plug it in it will work correctly for about the first half hour or so before it will stop reaching the internet. I then have to physically unplug the device and plug it back in in order to correct the issue. I was thinking of creating some kind of script that will automatically disable the adapter every 30 minutes and then enable the adapter. I ran into another issue here though. If I disable the adaptor (either from device manager or from "Network Connections) the device will change status from "Not Connected" to "Disabled." So far so good. But then, when I go to enable the adaptor again the adaptor disappears from the list. It's as if it isn't plugged in any more. The only way to get it back is to physically unplug the device and physically plug it back in. How to "Enable" the device without it disappearing from the network adapter list.
I am now on my second E4200... But still the same failure.. It looses the internet connection 5-6 times a day, and then I have to switch it off and on to get connection again.
Updated firmware was installed and settings were reviewed. Intermittently the E1500 looses its ability to connect only to our Android devices and "Cisco Connect" displays that it has lost Internet connectivity. The PC hard-wired to the E1500 and another PC connected wirelessly both work fine when this happens, despite the Cisco Connect message. The Android devices show the presence of the network, but they never "connect" - find the IP address. The problem can only be resolved by re-booting (powering off/on) the E1500. The loss of connectivity to our two Android devices and the Cisco Connect error display always are concurrent. E1500 looses connection to Android devices
we do have 2 Rv042, one in my office and one in my house.. in the office we do have static ip and at home none.. question is can i connect the two RV042?
I upgraded my Linksys from 160n router to 4200V2 router. I configured 3 wireless Linksys webcams and they work fine. After 24hrs they i cannnot connect the via HTTP and webcames IP addresses disapear from the DHCP client table. If reboot the webcames the it works fine for next 24hrs. I did not make any modification to any settings and the setting looks just like i had on the 160N router
I rdp into our server 2008 via IP. This is a router on ip 0.1, this is forwarded to my server on IP 0.3. This server was setup with DHCP default gateway of 0.1. We added a new outside connection on IP 0.2. I was talked through the changes so that internal DHCP requests went to gateway IP 0.2 but RDP still used 0.1. I plan on getting rid of 0.1.Where is the setting to change the RDP to use default gateway of 0.2?
I have been having some trouble with my internet for awhile now. It fine one second and than it will get really slow and eventually stop working. When I troubleshoot to see what the problem is it either gives me DNS server is not responding or default gateway is not available, sometimes it will give me both. It says it fixes the default gateway problem but it will show up again 5 minutes later.

I am looking to add remote sites that will authenticate with the Windows Server using VPN via Cisco rv042 routers in a gateway to gateway setup.My main concern is the placement of the server to the router and what would be considered best practice.In my mind, option 1 seems to be what I want - however, this would mean disconnecting the WAN feed to the server (my ip is static and tied into the MAC address of the server). While option 2 doesn't look right to me, it would leave the existing configurations in place which would minimize my downtime (I think)
I Connected two connection on my computer. One is LAN connection that is my Office network connection, and another one is USB Wireless device. I was using those two connection on the same computer. Now i office Network admin came and changed the Setting from the LAN Propertied. he removed the default gateway of my server IP address from DNS Server and he gave that ip address to the Default gateway in the LAN Propertied tab. After which i cannot access the wireless. If i change to ip address to the DNS Server my wireless is working..what is DNS Server and Default gateway..... Also i want to know the diffrence between that..
In my office environment, my machine is configured with an IP address, Subnet Mask and a Default Gateway. The Default Gateway does not allow internet connectivity but is configured to provide us with connectivity to some server based tool.
Now in order to provide us with the internet access, a proxy server is configured via the LAN settings in the IE. The problem here is the Proxy is restricted for some sites that I need like certain technical blogs and all, which it filters out in the blogs category and does not load.
I do have another Gateway server address that I can use in Local Area Connection IPv4 Properties as Default Gateway address which removes this restriction. I thought that this should be configurable to the LAN Settings as a proxy as well. But when I do so, I lose the connection to the internet.
I am not sure if all Gateways can act as proxy servers. Or is there anything that I am doing wrong. I am using the default port 8080 in LAN Settings.I can ask this from the technician but I am not sure if he would be able to answer that as he is just a first level guy. I thought of figuring it out myself.
I am trying to learn more about networking and system administration. I am practicing allot on VMs i am running here at home. I am not sure if it is allow to ask beginners questions on this site but i will try my luck anyway.
ipconfig /all reports one of my three DNS servers as 192.168.1.1. My Default Gateway and DHCP Server are also reported as 192.168.1.1. This is from a recently installed Valet M10 updating an old Linksys router. The Linksys reported the three DNS servers octets independent of the router's ip and other default settings.JK
FiOS gave me an Actiontec router that every other day is getting into a state where it refuses to give out IP addresses via DHCP. I have to reset the router to get it to work again.This seems ot have started in the last year, I assume due to some piece of equipment I added, or perhaps the VPN software or Windows 7 installed on my work laptop. I've not been able to figure out what is tripping up the Actiontec router, so I decided to try moving the DHCP function over the WRT610N that I have. I basically had the WRT610N setup without DHCP enabled, no NAT and no RIP, so it was basically just working as an access point. I left the Actiontec at 192.168.1.1 and assigned 192.168.1.2 to the WRT610N on the LAN side, while the WAN side is left disconnected.
I disabled DHCP on the Actiontec and enabled it on the WRT610N. I also set the DNS server to 192.168.1.1 so it would go to the Actiontec for name resolution. Using nslookup from a command prompt on a PC wireless connected to the WRT610N, I can see that names are indeed getting resolved. However, it looks like the WRT610N is setting itself up as a the gateway at 192.168.1.2. When trying to ping something out on the net, I get a message back saying that 192.168.1.2 is reporting the address as unreachable.
I assume this is because the WRT610N is handing out its own address (192.168.1.2) as the gateway. Is there anyway to get the WRT610N to hand out a different gateway address than itself? Optionally, is there a way to get the WRT610N to route requests coming to it over the Actiontec?I suppose I could just ditch the Actiontec altogether, but it seems a bit easier to use to setup port forwards and the like for various servers we have running. It also has a coax MoCA interface which I believe our FiOS set-top boxes use for their internet connectivity, so I don't want to lose that.
I've recently installed a new WRT610N router onto my small business network. Previously my network was as follows: Modem - Server - LAN where the server acts as a gateway using routing and remote access.
The addition to the setup now has the router between the modem and the server itself. After configuring everything - and DISABLING the router firewall and as last resort opening the server to the DMZ i'm having serious issues opening specific ports but not others.
To be specific - the server is sitting in the DMZ open right now. In my routing and remote access any port that I have being forwarded over to another computer is open from the internet with no issues. The problem lies with ports that need to be opened on the server itself with 127.0.0.1 where i'm getting a "connection timed out" from canyouseeme.org.
Why the local opening of ports is having issue? Before the router was installed everything worked great - however the router is needed for wifi and it cannot be configured as an access point only.
I used the Cisco Configuration Professional to add an Easy VPN Server to my 3825. I'm able to connect when remote but I can't ping the default gateway of 192.168.1.1 which is in the same network as the VPN DHCP pool. I can access every single other device on the VLAN segments but not the default gateway which means when i connect I can't look at my router. And there's more, I cannot ping anything offnet (ie 75.75.75.75).
Attached are some images which show some details from the client during the VPN connect and a few from the router (i had to use the lan switch as a jump host). If you can figure this out before I go back to the coffee shop to test this tomorrow I will send you a cake.
I have a Gateway 818gm desktop pc and the wifi stopped working after I reformated the hard drive. I can not figure out where the wifi card is in this PC.
I am using a RV016 (192.168.1.2) as a router and DHCP. It automatically assigns its own IP which is 192.168.1.2. I can not set my RV016 to assign a Default Gateway IP of the server. The workstations will connect to internet via this server (192.168.1.1)
When I create a virtual switch on hyper v, i lose network connectivity and the default gateway is missing I have to manually put the default gateway in and disable and re enable the network adaptor each time the server restarts in order to get network connectivity. I am running windows server 2012 Hyper V Virtual Ethernet Adapter loses default gateway server 2012
I have a RV042 router. The problem that I am having with it is that the DHCP is giving out the wrong Default Gateway and DNS Server. There is no option to change the DHCP server IP on any of the settings pages on the router. I am begining to think that there might not be a way to do it. I see that there is an option for the DNS under the DHCP page but the Public IP that is being handed out is not the one on that page. I also have 2 WAN connections hooked up as well a DSL link and a Cable link (the cable link is the primary one).
The following information is provided in an effort to resolve this issue: IP of Router 10.0.0.2 IP of DHCP Server (the one that is being handed out):10.0.0.1 IP of DNS (the one that is being handed out): 10.0.0.11
What I want to it be. IP of Router: 10.0.0.2 IP of DHCP 10.0.0.2 IP of DNS 10.0.0.2
I'm trying to configure ACS 5.2 so that should it loose connectivity to Active Directory it chooses the local authentication, however I can't seem to make this work.Within ACS 5.2, Access-Policies, Access Services, Default Device Admin, Identity,
I have a single rule configured for any device that matches tacacs to use the identity source of Active Directory, If authentication failed: Reject If user not found: Reject If process failed: Drop
The ACS can not access Active Directory, when I debug TACACS authentication on any 65k or 2921 device I get "Received Authen status error".
I have copied my computer's time in the router time setup under Time in the "tools" section of the router setup. After a few days of the router being up without a hard restart, it has lost 10 minutes somehow. I went to the logs and cleared them out and then looked at the entry showing that the log was cleared and looked at my computer clock and the time stamp of the log entry, and it was 10 minutes slower than my computer clock that I had originally set it from. I have a clock plugged in by the computer, and my computer always matches the clock that it plugged in, so I know it isn't my computer loosing time. What is going on here? Why does the router loose the correct time after it has been up and not unplugged or rebooted at all? I know that the router will loose the time if you unplug it, but this isn't the case here.
