Cisco WAN :: 2921 Dropping / Ping Time Out In The Connection?
May 14, 2013
I have a cisco 2021 router and I configured firewall and Site to site VPN on it, but recently Ism experincing and issue with, I have dropping in the connection and this issue, this make the VPN connection to have a slow performance and some time disconnection.
I bought a e4200 router about 3 weeks ago and after a power outage it decided it didnt like being connected to the internet anymore. So i got on the phone with cisco they determined the router was no good, mind you my laptop would connect wired. So they sent me a "refurbished" one, so i set it up. The new setup was wonky because it said the same message "Your connected to your router but..." then after trying to get the connection its self and failing it came up with "congratulations you are now connected to the internet". That lasted 3hrs and 45mins then died, so i went upstairs to power cycle it, it decided to connect with the old settings. That lased 25mins then died, so i reset it and reconfigured the router. Wouldnt connect, i checked my mac address and it was using my wireless one and kept turning on my wireless connection durring the install. So i cloned my wired mac address and got the internet for roughly an hour... then it died. So i reset it again and kept the wifi off got it going and decided to go to sleep. I wake up and its still working after 8hrs, i go down stairs with my tablet and i dies again. This time it refuses to reconnect, refuses to reset back up just doesnt want to work.
My Latitude D630 has been dropping internet connection all the time for the past three days. I looked up similar problems on this blog: a) cleared the DNS cache, b) downloaded windows XP- service pack 3, & 3 network software recommended for my laptop by Dell from the website and updated to the Intel PROSET/Wireless WIFI connection utility, d) ran ipconfig/all from C prompt and know the ethernet connections are disabled, e) called and checked with our local ISP and cleared the connection from their end. To sum it, I have tried everything I know and am still not able to maintain a steady connection to the net using WIFI. However I am able to connect using the cable to the router, so my net provider said the problem is with the wireless connection on the laptop. I didnt have this problem before.
Is the WAG320N iPv6 compatable ? ,or could it be with a firmware update ?.Is the X2000 in the same boat in iPv6 terms as th WAG320N ?.Is there a way of retrieving "UPTIME" / "DSL connection time" information from the WAG320N and also line attenuation stats etc.Wouldn't need the above but poor isp needs keeping an eye on.
I have a cisco 7609 running IOS version c7600rsp72043-advipservicesk9-mz.122-33.SRE0a.bin with the following modules..
sh mod Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 3 20 7600 ES+ 7600-ES+20G3CXL
The circuit has been tested as clean , so for the moment we have to assume that it is not a circuit issue We also have another idential 7600 in another POP with similar config that does not display the same problem

I'm having to reboot what is now my 2nd router every 1-2 days in order for all connections to resume working. My 2nd router was working great since Saturday afternoon, and just now I needed to reboot in order for my laptop to connect to the network.Now that it seems pretty clear the router in general isn't faulty, I suspected that the issue was IP lease related, so I was looking at DHCP settings and changed the lease time to 2880 (max setting), from 120 (default). However, this should only prolong how often i'll need to reboot the router. So, what is it that's causing my devices to disconnect or not being able to connect to the router for a prolonged period of time?
We recently upgraded to Windows 7 at work and my laptop was part of the first deployment. Laptops are imaged so that all configurations/software are already set and done. My problem is as follows, my laptop is part of domain, when I am at work I can ping anything just fine (network computers, printers) BUT when I am at home, I can't even ping my own PC. It returns back with the same address over and over. No matter what I ping when I am at home, it returns back with the same address. I can ping blah and it will display same address over and over. The weird part is I can ping websites no problem, but if i ping random names it will format as follow.Lets say I want to ping lost, below is what i get (I made changes to hide domain and IP)
Pinging lost.domain.com [188.8.131.52] with 32 bytes of data: Reply from 184.108.40.206: bytes=32 time=57ms TTL=50 Reply from 220.127.116.11: bytes=32 time=58ms TTL=50 Reply from 18.104.22.168: bytes=32 time=57ms TTL=50 Reply from 22.214.171.124: bytes=32 time=58ms TTL=50
Notice how my domain always shows up? When I am connected to the VPN at home, I have to log onto our intranet using the IP, I can't use the name, it wont direct to it.
I'm working as a network engineer for a service provider, and we had just gone through a pretty large scale upgrade throughout our network and service.But not long after the upgrade (or maybe ever since the upgrade, we can't confirm this because we probably missed it out due to many other links to be tested), we met a peculiar problem.Everything seems to be running fine most of the time, but there has been some weird 'ghost-like' activity which have been causing inconsistent network disruptions. At times, certain portions of the network can't communicate with other subnets.And most obviously is the problem with a continuous ping and a traceroute simultaneously. Ping is usually normal, but until a traceroute is attempted, it times out at the same time as tracert fails to obtain the route.Besides, performing a ping from the 2nd closest hop address, 10.250.253.251, which is a cisco layer 3 switch also has problems, the results shown are as belowType escape sequence to abort[CODE]
They time out however I can connect to google/ect on my browser.

I have newly deployed network. I have two ASA5520-AIP20-k9. both connected to ISP and configured as Active/standby failover. the ASAs were working fine at first but later on, the internet connection becomes very slow. the ping reply i am getting from my next hop(ISP router) varies during the peak hour is some times in 2000 msec or above but during off hours, the ping reply time is 1 and 2 msec. when I directly connect my laptop to the link that comes from the ISP its ping reply is 1msec and 2msec. I thought the ping reply of the ASA5520 to the ISP gateway should be constant and should be 1 and 2 msec regardsless of the traffic passing through the firewall.
My customer has various Cisco switches but only cisco 2950 switches has the problem of ping timeout or reply time is too long(average more than 2 sec). It will cause I Network Mangement software alarm always.
I have a fresh out the box asa5510 with 8.4 on it.I have built these before but for some reason cannot get this one to work. I am consoled on, have applied the following config but can still not ping to or from, can not asdm, cannot http/s. Arp table shows device it tries to ping, but device trying to pping it has incomplete arp entry. [code]
I have a brand-new WRT160N router (just installed FW v3.0.02) that I am using in mixed mode, 20MHz only, Channel 11, not filtering anonymous requests, beacon at 2306, RTS at 2307, fragmentation at 2346, MTU at 1400.
These settings bring the response from a simple ping command over the wireless network down to approximately 6ms on average, which is good. However, when I still noticed inconsistency with my internet response over wireless, I decided to do a test.
By simply running the "ping" command on 192.168.1.1 (the router address) over the wireless network repeatedly (approx 3 seconds between commands), I can see that approximately every 65 seconds or so, router response time increases to over 100ms for a few seconds, then decreases down to 6 ms or so for another 65-70 seconds. See the chart below. The interval looks pretty consistent to me, with the exception of one stretch where it goes for over two minutes without a spike. I see this pattern regardless of what else I'm doing over the network. I do not see this behavior running the same test when physically wired to the router (ping response time is a flat line at 0ms).
I would like to know if it is possible to make a solution with Anyconnect where remote user´s PC start an automatic VPN connection via Anyconnect as soon as the users enter their Windows Login and password on their notebook.
I was thinking of using computer certificate for this solution so it is completely transparent for the user which is the requirement for this solution.
currently I have a Cisco 2921 router and I have one active site-to-site VPN connection through the internet.my question is; how I can create another Ipsec site-to-site VPN connection ? I have to keep the 1st VPN connection active.
i recently purchased a D-link n300 DIR-632 (wireless router), i ran the setup wizard and it seems to work. HOWEVER. for some random reason the data transfer will cut out for around 30 seconds or so and all activity is halted. I have looked in the routers Settings however i am not comfortable with messing around with to many settings incase i completely screw up the network. Is there a setting that i have to change so that my network will run more fluently. It is a 300mbs data transfer and there is a maximum of 3 devices running from the network at any one time. I am trying to play online games and the network will lag and freeze the game causing it to crash and have to be restarted. ALSO i would like to note that this router is LAN enabled too. The main computer running on this network is connected by a LAN cable and is still having the same data issues as the wireless devices....
My lan conenction keeps dropping on my desktop, we have two other Pc's attached to the same router (bt business hub) and they are always working, however my Pc runing win7 64 bit says its connected to the router and assigns an ip but its not connected to the internet? ( until i do a restart)
Ive fixed the IP and DNS- still dropped reinstalled drivers for NIC- still dropped Restored machine back to a few months- still dropped, checked the cabling and changed- still dropped
I could understand this if it wasnt finding the router or IP and if the other PCs showed the same symptoms, however thats not the case and its reallt confusing.
I have a TG782T Thompson Gateway, and a few months back we had a lightning storm where it hit the ground fairly close. Ever since that storm, on a regular basis our DSL connection on the router keeps dropping out. Also the phone that we had at the time was shorted out and we had to buy a new one.
I have noticed a few times over the last month that my PC would not load pages due to connection problems. If I hover over the Network icon, it say that I am not joined to a network but within minutes, it reconnects itself. I use http://www.scan.co.uk/products/zyxel-pla-4201-500mbps-mini-powerline-adaptor-twin-pack power adapters and they "appear" to work well with good speeds as I download and game online alot. I have noticed that today the problem is really bad. It loses its connection every 5 or 10 minutes and then reconnects itself as if nothing has happened. I tried using my iphone on the wireless and it also seemed to have dropped out on connection. I have tried resetting my router too but with no joy
Recently I have been having problems on my home Wi-Fi connection. Every so often, I drop my connection. It happens many times during the day, and it is really starting to annoy me.On the Wi-Fi connection, are 3 other laptops than mine connected to. About 3 months ago, the problem began for me, only recently have the others also gotten the problem. As we stand now, we are all craving for an explanation.
My atheros ar9285 wireless network card continuously drops my connection, now I've seen other topics about this put there solutions dont work. I hear McAfee can cause problems? It is on a asus k5dij laptop and my wi-fi is provided by bt using a bt home hub 3 type b. Find attached my Xirrus screen shot and my cmd ipconfig when i learn how to get it on to this website.
For the last couple of months we've been having problems keeping a connection to the internet. The green light turns red and everything loses connection while it cycles back on. I've tried everything I can think of and am at a total loss as to how to fix this.
The ISP has been out twice to check and replace all the lines and install a cat 5 line to no avail. I thought it might be an ip conflict dropping the connection so I assigned everything its own address and that didn't solve anything. I have a brand new netgear n300 router/modem that replaced the Actiontec one the ISP provided because I thought that might be failing, no change. The next thing I tried is to turn off and disconnect everything from the network except my laptop to see if it was a certain device causing the problems. It seemed to be going well for about an hour when I lost connection again. The next thing I tried is to hook it directly to the router and turn off the wireless to see if that worked any better, connection still dropped. When the guy was over here replacing the lines, he mentioned that he had just come from another house on our block having similar problems so now I'm thinking maybe they have to fix the lines on the poles. It seems to me that the most likely thing is that the connection is dropping from the ISP to the router, what I could try before I called them up to tell them the problem is definitely not on my end.
I have had comcast for 4 years and for the last two years my comcast connection had been dropping. At the time I didn;t take it as a big deal because I have bad connection but not it's way too frequent to ignore. I have gotten a new router and exchanged a modem from comcast. Basically at a random time of the day internet just goes off. To fix it, I have to go up to the router and disconnect and reconnect the router. Even sometimes it doesn't fix the connection so now to fix the dropped internet everytime I do the following procedure: Unplug ethernet cable from modem --> Unplug the modem --> unplug the cable that connects the modem and a Y-extension for TV and internet
I'm looking to improve my connectivity,as the internet drops out a few times a day.Let me explain - I hope I'm correct in my assumptions.Every few hours, my PS3 will have a DNS error, and upon checking my iPhone, I notice that it's switched from wifi over to 3G and there seems to be a loss of connection. I cannot reconnect to the internet until I've restarted my router, or 'forgotten' and rejoined the network.
Additionally, we have an Apple TV, and connection drops out about 3 or 4 times every hour, which is very frustrating when trying to watch a movie.
I've had it for a little over a year and its always been really good with internet connection, strength-wise and speed, never dropping below 95% and just a Megabyte or two off from my corded computer. I have a high end d-link network card in two other computers as well and they each experience the same problem. So something is up with the router. Frequently, when I connect this specific computer to the internet, it drops wireless signal completely and won't connect for any computer for a couple minutes. Then suddenly, out of the blue i'll regain connection. Also, i used to always get a strong 35 Mbps on wireless, which I still do on corded, but now i only do on rare occasion. Most of the time i'm stuck at 12 or 14 and even more often, it drops to 1 or 2. Very unstable. I have reset it it multiple times, along with my modem, still same old problem persists...
My WOW internet connection keep dropping out. I recently went form AT&T dsl to Wow but as I surf my internect connection drops out. Could I have some software conflicts in my computer since I converted from At&t connection to WOW. I used a At&T Gateway 2 wire router before installing WOW. I don't have a router connect to WOW at this time. I am directly connected to their modem.
I changed my ISP (I don't know if that has anything to do with it).I have my network setup so I have a seperate modem (tp-link td-8616), which is connected to my router (asus wl-520gu) and do most of my computing from my computer (running Windows 7 64 Bit Home Premium, wired network). I had installed tomato firmware onto my router, which was working fine with my first ISP. I changed companies about a week ago, and noticed my connection kept being dropped. At first, I thought it was an issue with my ISP, so I called them up, and didn't find a solution.
Afterwards, I started doing some trouble shooting on my own, and noticed my modem was still connected (via the WAN LED, at least), even though my router disagreed. So, I tried connecting directly to my modem and my connection would be fine without any issue at all, so I thought I'd trouble shoot the router. I switched back to the factory asus firmware, connected it back to my modem, and after a while, it disconnected my LAN connection again. My router comes with this somewhat annoying interface that tells me the issue is "You have set the wrong dynamic or static IP address for your wl-520gu." So, I investigate that, and here is the setup:
My modem is statically 192.168.1.1 when I directly connect to it, so I left that setting alone.My router is also 192.168.1.1, but this was how tomato worked, so I'm not sure that this is the conflict, so I tried setting it to 192.168.1.2, which does not seem to fix the problem.My DHCP settings are set so connecting computers are 192.168.1.100-254, which should avoid the conflicts.
