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.

View 1 Replies View RelatedMy 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.
View 3 Replies View RelatedI 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.

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.

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

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.

View 13 Replies View RelatedSomething strange is happening to my Cisco 1941W. Every time I reboot the router i loose the running configuration of the service-module (Access Point module). The weird thing is that the router's configuration remain the same. I made sure i save the configuration by issuing the wr command on the service module console but still happens. My router's current IOS version is 15.0(1)M1 and my AP's is 12.4(21a)JA1.
I also did another test by making sure the startup-configuration was identical to the running configuration and when I reload the router still happens.
I have a DIR-655 Rev B1, FW 2.01 (I will probably upgrade the FW tonight to the latest.)
I have at least 20 items that connect wirelessly to this router (2 PCs, 2 Laptops, 2 Tivo Box, 3 Game Consoles, 3 Cell Phones, 2 Tablets, 2 TVs, Printer, AP Gateway, and some other projects) It's been a solid connection to everything for the past couple of years.
I bought a new Dell Inspiron 15r SE laptop (uses the Intel Centrion Wireless-N 2230 Wifi Solution.) After anywhere from 2 - 10 mins of browsing/watching a video/downloading files the access out to the internet simply stops.
At this point I'm still connected wirelessly to the router, and if I go to the router address I still have access and can login and see the router settings. I check and there's plenty of time left on the lease (days.) Still not getting internet access. Eventually my Laptop will disconnect and reconnect (or I do it manually.) I've performed hard resets of the router, I've had my laptop Forget the network and then reconnect, etc. Nothing has resolved it.
I thought it may be my laptop, but I've taken it to Starbuck, Work, Neighbors WiFi, etc and I don't have any problems staying connected on their networks.
I've had Dell on the line, we connected hardwired, and there solution was to force forget and reconnect to the router, which worked for the 10min he was on the line with me, but then failed soon after, and back in the same connectivity hell

View 1 Replies View RelatedWe have some 1242 LAPs in a two 5508 controller setup working fine. All LAP are configured to obtain address from DHCP. After first join we usually change some configs like HOSTNAME, AP GROUP, PRIMARY AND SECONDARY WLC. After a software restart or a complete power off/power on the LAPs joins the primary controller and all configuration still there. We now add a 1142 LAP and is does not retain the configuration after a power off/power on cycle, but after a software restart there is no problem. The only way to retain the config is setting the AP with a static IP address.
We use WLC 7.0.116 and we see no errors in the LAP console.
I have an e4200 with the latest firmware 2.1.39. I just upgraded the firmware due to connection issues with my DSL. I now have the same issues with disconnects but I believe they are being caused by a different issue. When I try and log into my router through the IP address it wont let me, it says it can't find the router. Eventually after getting in the first time by using the default password, I have twice found out that all my settings are gone. This has happened twice this week and only happened after upgrading the firmware but I can not tell if firmware is causing it or if it is hardware related. I now reboot and restore saved firmware but that is a hassle and am pretty sure that is not the way it was designed to work.

I have an EA4500 router. It's the latest in a long line of Linksys routers I've owned and I'm pretty familiar with setting one up and making changes. But the EA4500 seems a bit more picky than previous routers. Last night I tried to enable port forwarding for ports 53, 80, and 88 for my xbox. I already had port 3074 forwarded. When I did that and applied the change, I lost all Internet connectivity. I tried cycling the power on the router with no luck. I finally got connected again by going to 192.168.1.1 and disabled those ports. The status page then said I had Internet connectivity but I really didn't at least right away. It took a couple minutes before I was actually able to to connect to the Internet again. What else should I check when it says I don't have internet connectivity?

View 6 Replies View RelatedI 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 have Roadrunner Turbo and when it's online it works fantastic but after a couple hours or a days the modem loses it's connection for 30 minutes to many times a whole day or two.
When it loses it's connection I've tried disconnecting the modem and the router, waiting a minute and plugging it back in. I've tried reconnecting the cable wire and nothing works. I've even tried going to the TWC center and replacing the modem with a new one and it still happens.
The router I have is a WNDR3700 and it works great. We never lose connection to the router but the modem will lose its connection for when this happens the router's usual lights are on and we are all still connected to the router but the modem has only 2 solid lights and 1 blinking one.
