Cisco VPN :: Disconnecting On ASA 5505
Feb 21, 2011
I configured site to site vpn between asa 5505, in one site it is static ip and the other side is dynamic ip.my issue is the the tunnel is automatically going off maybe 30 minutes time, if it is idle again if i initiate from dynamic side it ll comeup.and my setup is like this,in the static ip side i am having ADSL line , so i connected to the adsl router and the adsl local network is outside network of asa 5505.like dual nat is there in the vpn connection.

My company has a DCS network that was previously segregated with a layer 3 switch and a handful of access lists. However, there came this big push to segregate all DCS networks with Firewalls, so I purchased a 5505 and duplicated my simple access lists on the firewall and everything worked. There is no NAT, just explicitly permitted traffic out and explicitly permitted traffic in. However, there are some applications that connect and work fine for a few hours, then disconnect and the user must exit out of the application and go back into it, then it starts working again. Previously with the Layer 3 Switch/access lists, this never happened. Since I put the firewall in place, it has happened 3 to 4 times a day every day for the last week.

I got a new gigabit router to up grade my old one in my current home network. The old router worked with everything including the problem PC. The new router works with everything (wired and wireless) except one PC.
To narrow it down I connected only that one pc with a wired connection to the router, removing all other devices. The problem still exists, so it's either a router or pc issue.
The pc will connect fine and I can access everything on the LAN and internet for about 5 min. Then I get limited connectivity and I need to do a release/renew to get the connection back.
While the PC is dropping all other devices that I connect to it work fine with no interruptions (wired and wireless).
I tried reseting the router, reinstalling NIC driver, setting a static IP, and messing around with the speed and duplexing options on the NIC. I plug in the old router, the pc connects with no issues.

After hours of testing and configuring I can say it’s not the same issue as discussed in the link above. I have the same problem as mentioned at the beginning.
Our set-up: We have Mac, windows and mobile clients and Cisco networking equipment. We would like to use the WAP4410n as our access point. However, 10-20 minutes after connecting to the access point, the connection doesn’t work anymore. It happens randomly and not only during large file transfers. It also happens when I’m not even using the computer. After disabling and enabling the wireless interface on the client I get back the connection (for the next 10-20 minutes).
I not only tried to change all different settings on the access point (channel, encryption mode, ssid, channel bandwidth, ...) but I also changed settings on the Mac (disable IPv6) but it’s still not working. Of course I also tried older firmware’s.

So far I have tried doing a factory reset, power cycling, upgrading my firmware, and changing my channel [even though there weren't any interfering networks on the same channel in my area].
This problem started a while ago and has been going on for several months now. I will lose access to the internet for a brief period of time [1-2 seconds], but this is very annoying. I will exit conversations on MSN, downloads will stop sometimes, and it is virtually impossible to play online multiplayer games since I keep losing connection every five minutes or so.
The connection works just fine when I connect my modem directly to my PC.

internet won't stay connected for more than 2-4 minutes at a time. I recently got a new modem, as recently as two days ago. It connects fine but within 2-4 minutes it disconnects then reconnects itself within 20 seconds. It's a plusnet modem and in the corner of my screen I have a little computer screen with 3 signals coming out if it which flash. It's called Wireless Network Connection Status. Beside it are 4 bars not too dissimilar to mobile signal. They too are green and when I click into it it's called Dell Wireless WLAN Card Utility.

Haven't been here in a while after going to grad school. My internet keeps on getting disconnected, and I keep having to unplug the power cord, wait 10 seconds, and then it works again. But this has been happening quite frequently. Is it because I need a new router? It is Linksys SRX 200 router it says.

i recently bought a wireless USB adapter so i can connect to my router as my older one broke. The one i had before worked fine and was easy able to connect to my router with high connection, but with this new adapter i can still connect but have pretty low signal like 2 or 3 bars and whenever i try downloading anything or try watching films or just surfing the web for like 10 minutes it says limited access with a yellow exclamation mark on the signal bar and the only way to reconnect to the internet is to first disconnect and reconnect every time.

nic shows disconnected every second, shows "no cable connected" Windows 7 pro, PC next to it (same model, same settings) works fine, switched cables and the one I am on works just fine on either cable. Updated drivers, ran diagnostics, no fault found. DHCP; tried changing link speeds, tried EXACT same settings as PC I am on. Domain settings correct; PC will connect on a different subnet.

I've recently had this trouble where whenever I'm playing a game [such as Sims 3] my Laptop Internet connection suddenly disconnects and I am unable to reconnect to my Internet since it doesn't come up on the connection list, so In the end I have to restart and it all happens again if I start playing again.

My HP home vista keeps on disconnecting.I use dial up. The IPS service provider said to plug the computer directly into the phone jack without using the splitter which is a plug that has two openings(1 for phone and 1 for the computer in the event that the splitter is bad) I tried this and as soon as a connection is made about a minute later I'm disconnected again. Any ideas as how to resolve this problem? Also I was told that if I have DSL that this wouldn't be a problem

We are using Cisco router (1941W model) and our the WAN interface keeps going down randomly (sometimes happened twice within 1 hour, sometimes worked fine for 2-3 days before getting disconnected). After getting disconnected, if we unplug the cable that connects our router to the fiber terminal and then plug in back, everything works fine immediately.
We had asked our Internet Provider to come 3 times to check the network line, renew the fiber terminal and do some investigations, they said there should be no issue on their side. If it's true then there must be something wrong with the router.
We also enabled ip accounting on the router and saw very low rate of small packets coming to WAN interface.
During the downtime, LAN interface still worked fine.

Since few days the WLC 2100 series controller and 3x LAP1131AG are getting disconnected and the controller gets offline via the local ip address. At that point I have to reboot. To get anywhere and after I connect wirelessly to the AP before I know it it disconnects. It worked for 3 years straight no fuss. And now nothing. I reconfigured the WLC 10times and no diffference.

We have an ASA 5510 running 9.1 and the latest 3.1 AnyConnect package for Linux. The problem that i am having is that the AnyConnect VPN will drop after maybe 30 seconds or less of connection. It will connect fine. I can ping my remote servers. Then it will drop and go into a "Reconnecting State". Of which it will not reconnect. I have to close AnyConnect and then try to connect again. Then I'll get the same results. We have about 25 employees that use the AnyConnect VPN all day on Windows 7 machines without any problems. The issue appears to be isolated to my Ubuntu laptop. I have gone so far as to completely reinstall Ubuntu, both 64 and 32 bit versions but end up with the same results.

For the past couple of weeks my internet has suddenly disconnecting on almost a daily basis.Windows troubleshooting the problem always fixes it in seconds and I usually have no further problems during the day but it's getting annoying and I'd really like to know what the issue is and how to fix it.It happened again just now and Windows Diagnostics found the following problem: "Local Area Connection" doesn't have a valid IP configuration.I'm running Windows 7 and using an ethernet cable, no wireless connection.

I have had this problem for a week now. We have a desktop, PS3, and 3 laptops connected all at the same time. No problems with the desktop, PS3 and one of the laptops so far, but my Asus A53E and the HP Pavilion keep getting disconnected every few minutes! I recently installed a Linksys router (just to try it out) and it didn't really do well so I returned it and switched back to our old router which is the DLink DIR-625 router. It was doing okay for a few days and then suddenly it just started going crazy. Both the desktop and the PS3 are connected to the router through cable, but the other laptop (Dell) is not. I don't understand why it's just the Asus and the HP that get disconnected a lot. I already tried updating my drivers and reformatting my laptop, but still nothing. I don't want to call our ISP (Shaw) and D-Link because the internet works fine on the other 3.Additional Information:
-Modem
-Microsoft Security Essentials (on the Asus)
-avast! (on the HP)

I have a Netgear Wireless USB Adapter (WNA3100) for my PC. The router is in the other room (approx 5-6 meters away) connected to my flatmates laptop. The adapter worked fine for almost two months, but at the past 2 weeks it keeps disconnecting in every 2-15 minutes, for 1-3 minutes. I have Windows 7 and I'm not familiar with networking issues so the only thing I did was to reinstall the driver and update it, but this didn't work.

About 2 weeks ago my router began acting up. It disconnects when I'm just browsing, downloading or streaming a video. I tried everything! I changed the channel on the router, resetted the router numerous times. I connected the ethernet cable from my pc directly to the modem to see if it was in fact my router and not the modem. My pc never disconnected once while connected to the modem. In order for me to download something or stream a video I have to connect my pc to the modem and it is becoming a pain!

I recently bought my new Alienware laptop and it would connect to the wifi but no internet. Sometimes it works for a second or 1 minute. Now it's just a triangle with an exclamation mark saying it has no internet access. I already tried the power management. I am using a router; the other laptops in my house is fine. Could it be because the router couldn't support the internet of the Alienware? I remember seeing routers saying "Good for gaming!" something like that. I've been having this problem for 2 days now.

Happens every few hours, but is fixed by reconnecting my router. Although this is inconvenient because I run an IRC chat and a small web server. I'm not sure if those would cause such a problem, but I hope not

Some of you may remember my name from the PS3 posts I had a while back. I completely abandoned the PS3/internet connectivity issues due to it going unsolved for about a year now, I just moved to a new house recently. I can understand that it will take a bit for the family to set things up like reliable internet connectivity and what-not. But perhaps there is something that I can do relatively quickly to fix this. Perhaps it is problematic software on my computer? Here's what is happening: The internet disconnects. A lot. Sometimes it's once per 7-minute YouTube video, and just recently it was a record-breaking sixteen times within 20 minutes. I read some things about it being a problem with Adobe Flash player, because most disconnects happen during YouTube videos, but I can't get an update for it... the internet does not co-operate.

I am connected to the router with a cable , a router which my internet provider supplied me with.The problem used to happen before , occasionally , but the disconnecting has drastically increased lately , and these days it has become unbearable , it occurs at least once every hour , especially when i'm playing a game online or so.The disconnects last very shortly , or until i reset my router or disable/enable my network in network connections.I have 2 more laptops in the house , connected via wireless , and they've had no issues with this.The first time these problems occurred i was able to fix it just by doing the windows troubleshoot, which lead to an error saying "Default gateway is not available".I found a lot of threads on the internet regarding this issue , and tried all of them but none seemed to work.
I tried downloading newest drivers from my motherboard site first , then from Realtek's site, then deleting old drivers via DriverSweeper aswell , just in case , but it did nothing.I tried changing the Speed & Duplex to 100mbp/s Full Duplex , which has solved the issue for some , but again it did nothing.I called my internet provider , was told to use static IP address and type it in manually and if it didn't work to try plugging the cable into another slot on the router ,And after all those things , i feel like the problems is even bigger now. I now no longer get the "Default gateway is not available" error , and the only solution is to reset router or disable/enable network , which leads to the network being "unidentified" for some time before it connects.
