FVS388 VPN Suddenly Dropped
Mar 3, 2012
Yesterday while at work our VPN suddenly dropped. We have a site to site VPN that is connected by a Sonicwall TZ180 and a Netgear FVS388 on the other. I power cycled the SMC Comcast modems on both ends, along with the Firewalls too no avail. The odd thing is both the TZ180 and the FVS388 IPSec has been established, but for whatever reason I can not ping either local host and no data is being sent or received. I verified no settings had been changed on either modems or firewalls. This setup has been up and going for a year plus with zero issues.

2 days ago I turned on my pc, went off to the internet and boom. It's slow. I thought that maybe its about my provider. No it's still slow. Weirdest thing is that my torrent dl speed is still about 100kbps. But when i want to download something with my browser(s), speed is just about 20kbps. And surfing on the internet is slow too. I'm using windows 7 32-bit. And i use wired connection. And since I have XP installed aswell, I tried the internet there. I was having no problems with it there. But I use win 7 and I need this problem fixed. I have even scanned my pc for viruses. Nothing.

2 pcs connected with a TPlink modem/switch. wired connection.One pc running win7 64, other xp sp3. Both home pcs..Used to get about 10mbs transfer speed. ( I know its low, but was more than happy with it as I never use it to transfer large files.But suddenly transfer speed changed to just 8kbps. Its kind of a speed limit activated.I can just browse files and folders but cannot copy at 8kbps.

I bought a new system case, installed everything from the old case added 2 additional fans and now my wireless network speed dropped from 150 to 54 aand I have no clue why. New case has a bottom mounted PSU and old had a top mount so netcard sets about 4" higher then it used to but other then that nothing has changed. Also when I brouse thru things I noticed this "LocalSystemNetworkRestricted" allot of places and do not remember seeing this before, I have used a different system to check out my router and it is same as always.

They are all on the same domain but some of these users are getting dropped from the Internet, and email. Once they restart there PC it works for a couple of hours than it drops again. We also tried updating the network driver after doing that it works ok for a couple of hours after that they start lossing connection to the Internet and email again. We have tried several different things but have not being succesful in finding the issue.

A few days ago I sent my ISP an email and a few days later they called my house and talked to my mom about the support issues I had addressed with slow speeds. They directed her to www.att.com/speedtest and our internet speed was reading 6MB/s down and 512kb/upload as it should be.The problem is, outside that test I am not seeing the performance. Let me put it to you like this, right now the internet is so slow that Speedtest.net consistently gets errors when trying to connect for a test. Any website that isnt text based like say Reddit, takes ages to load. Youtube videos? Streams? Forget about those, 240p buffers as slow as 720p.When I finally manage to get Speedtest.net to do a test after numerous internet resets I barely crack 1MB/s down IF AT ALL, and .12kb/s upload IF AT ALL.
Its maddening. Its actually affecting my siblings college work as their online tests have been failed due to disconnecting.Something I should have mentioned earlier is that I do have a router. Its a Linksys WRT54GS with the latest firmware. Something that is also annoying is that when I plug my internet directly into my computer, it wont work, but if its plugged through the router it works just fine. This has never happened and its making me draw a blank.AT&T support suggested the we upgrade our Modem to one of the newer ones that are a modem/wireless router combo which we plan on doing. Right now we have a Speed stream 4100 that weve had since we got the internet in 2006 and I guess they don't even make them anymore.

I have a Dell Latitude d810 laptop that has XP Professional and an Intel PRO/Wireless 2200BG driver. It has been working fine for nearly 3 years. Recently I changed it from a domain to a workgroup and now the internet connection drops after about 5 - 10 minutes.When I say "drops", I am referring to the browser can no longer display the webpage. The internet connection still shows to be "Excellent". I even tried pinging www.google.com and it can still ping the website but the browser just stops working. I have tried Firefox and IE.I updated the DNS to use the default primary DNS suffix. The only way to get the browser to re-establish a connection is by rebooting the laptop.[CODE]

where my internet dropped alot while playing ps3.i switched from my horrible d-link router to a DIR-655 Since i bought it, i've never dropped but my connection speed is an issue when playing my ps3.I use a wired connection through my router.some periods during the day it's 2 mbps download.. that's really slow considering my computer has 20 mbps download through wired connection.some periods during the day it runs fine @ 4 mbps - 5 mbps download (this is fine for gameplay but it lags a bit)if i directly connect my modem to my ps3 - it goes 20 mbps download (amazing fast speed)I called d-link technical support and did everything from port forwarding to turning on DMZ and putting my ps3 IP in there. I have a 2 part question: is there anything i can do to boost my ps3 connection download speed as high as it would be if it was connected straight to my modem while using a wired connection to my router? if that's not possible, is there anyway i can keep a stable download speed @ 5mbps?

Despite all the drama regarding the DIR-615, I've had the B2 revision since around late 2008 or early 2009 (can't remember exactly, most likely late 2008) and it had been working flawlessly. And I do mean that. I never once had a problem with this router and highly recommended it. Back then I was on a 24/1 connection, and had been up until recently.
Now I'm on a 100/10 line, and things haven't been looking too great. The internet is stable for the most part, and I am getting full speed, but the router has been starting to drop its connection a lot. I've had to release -> renew (or simply restart the router) quite often now and it seems to be happening at complete random.
weaking with settings, updating firmware, etc but no luck. All connections in question are of course wired, not wireless.

Router is running with IOS 12.4(24T) and we are having problems like file download stalls, some emails not being send or received. CBAC is enabled on this router with default values. MTU is also the default value. This problem has started all of a sudden. seeing lot of errors in the logs as below:

yesterday at 6:30 am my internet was working fine.yesterday at 7am it quits working.the computers through the house are 2 desktop PC's, one netbook, and one laptop.the 2 pc's connect to the router via a switch.the netbook and laptop use the wireless router.the wireless router is not specifically just a wireless router, it goes both ways (hardline and wireless)after 7am, the netbook still had connectivity to the internet via wireless even though my laptop did not.the internet is still connected to all of them, browsers like google chrome, firefox, and IE7 do not work. but just like a browser, steam's store will not load.here's the funny part, the netbook still had browsing ability until 7pm last night.we checked all the ip's and MAC addresses on the computers to make sure nothing was conflicting.nothing was.packets were coming in and out at normal rate but none of our browsers worked.we do have comcast, and my father told me that comcast gives you norton for free for using them.i have read on here that removing norton magically solves the problem but 3 of the 4 computers does not run norton. and i also do not see the logic behind this.we have also recieved emails from comcast exclaiming that they have reports of "bot emails" coming from our I.P.'s could this have been an attack on our network or some network virus?

The computer in question is one of 30 computers in the same office that is not currently experiencing this same thing. All connected though the same switch, patch panel, etc. Testing has proven that the switch and line is fine.We have a server set up for all of the multifunction printers on property and we simply map the printers through this unit.We have an exchange server for email.File server... for... files. Okay, here is the situation. This IBM desktop will be connected to everything, able to print, email, connect to files, etc etc.Then, or so it seem, will just lose its connection. no email printing etc. She is asked to put in her network credentials again. and usually this works. (it seems that the network dropping out may take up to 3 minuets to fully restore and she tries to put in her credentials too soon).After each event she is able to restart her computer or type in her credentials and get back to work.. after mapping the printer again.

we got a Sonicwall router and we have been having stability issues. Every 1 minute the TCP connectio is dropped as well as UDP packets. This router is connected to a T1 connection and its requesting a DHCP lease every couple minutes as well. We originally had two WAN connections, and we have disabled the second one because someone thought it was that, but obviously it has to do with the internal network. This is a dual WAN router.

My DIR-655 drops WiFi connections every few days. All wired connections are fine. Rebooting the router fixes the problem at that time. Cable modem works perfectly fine. [code]
I'm sure I'm missing some devices, but that should give you the general mix of wired/wireless devices that I use. I'm single with visits from my son every other weekend, so network traffic is not that high at my house. I've had this router for a couple years now and didn't use to have this problem. I've been updating the firmware, and I suspect this problem happened after on one those updates. I just don't know which one. Also, I didn't use to have any neighbors with Wireless Routers (that I could detect), but recently there have been 2 who have gotten them. I was hoping this was a problem that D-Link was aware of, but that does not seem to be the case. I would hate to have to go out and buy a new router (not D-Link).

When I bypassed the router and connect my pc to the cable modem directly, my download and upload speeds are over 20mbps/10mbps. But when I connect my cable modem with the router, it reduced dramatically to under 10mbps/5mbps.So the bottleneck is with the router. How can I troubleshoot the router to remove this bottleneck?

one last try before boxing up my new DIR-655 and taking it back to Microcenter. I've opened a case via email and got the standard response, below.I have a Dlink DP-300U print server that works fine with my 'old' Belkin router, a F5D-7230-4 wireless unit. Nothing wrong with the Belkin, I'm just getting some service drops from my lousy AT&T ifitl 1.5mbps ISP and thought a new router might work. I actually read the manual (!!) before installing the DIR-655 and even followed it. The print server just isn't visible on the network. Everything else is, though. The 'suggestions' from Dlink tech support below are very useful. If I could 'see' the print server to verify its IP address, we wouldn't be having this conversation. I've rebooted everything, several times and even reinstalled my old Belkin router (which always sees the print server.) And Dlink, no...I'm not interested in paying you $32.95 for up to a half hour to maybe fix a problem caused by your new device. And dropping my call after almost 15 minutes on hold is not cool, either. With reference to the issue you are facing, we suggest you to kindly ensure that the IP address assigned to DP-300U print server is in the same network range as that of your DIR-655.
NOTE: The default IP address of DIR-655 is 192.168.0.1 Once it is done, try to ping the IP address of DP-300U using any of the wired / wireless client connected to DIR-655.note the DP-300U is not currently supported in North America. D-Link offers a premium fee based support line that will be able to support any issues you have with this product.

I have some remote locations that connect to my ASA 5510 cluster (Aktive/Passive) using the Cisco VPN Client, from which the connection gets disconnected at random intervals (could be 5 minutes, but sometimes after 15 minutes). However, some other remote locations do not have this problem. All locations have the same VPN client configuration (distrubited by pcf file).
I already disabled isakmp keepalive on the ASA but this did not work. If I read it correctly, the Cisco vpn client logging shows that the ASA initiates the ending of the connection.

I am using WAP4410N access point to connect 5 computer to the network. Recently the wireless network is very bad; pakets are often being droped, very high reply times. I have upgraded to the latest firmware tried to change configuration with no use i even tried the default configuration. I assumed that there's interference. I tried another AP ( linksys one) and things seems to be okay. what would be the problem with AP?

I am truly struggling with the changes after 8.21. I am trying to get a VPN up between two sites. This is the B end, I am sure there are a bunch of problems in the other end too. Eg. the tunnel NAT does not have the right priority 1.when I establish the tunnel I get this:

So I have an asa 5505 running ipsec and anyconnect and it has been working great for months. I have not made any changes to the config, but suddenly all of my anyconnect traffic is being dropped. The vpn uses the same subnet as the LAN. I tried putting a rule in to allow all traffic from the LAN subnet on the outside interface. Now I just get the WEBVPN-SVC Action-Drop in packet tracer.

I am using Windows 7 Home premium SP1 (x86). I can connect fine and after a (seemingly random) amount of time the connection will drop (at least according to windows). I can also easily reconnect without a problem, but it will not pick back up the connection automatically, which is a problem because I use programs that need to access the internet and Often leave large files to download while I'm sleeping or not home. So If I'm not sitting at my computer to manually reconnect, then whatever i'm trying to accomplish doesn't get done.I'm using the ALFA AWUS036H USB wifi adapter. I had previously been running windows XP and this same thing would happen (though, much less often) but when it happened in XP it would automatically reconnect in a few seconds. I downloaded the drivers from ALFA's website incase the ones on disk were not up to date, and I tried both of them (they have a "normal" and "power control driver" option) and the problem remains. Also, I've never used an external wifi adapter before so I'm not sure if its supposed to work this way, but there are 2 "signal strength meters" in the system tray the standard windows one that you can click on and see available networks or go to windows "network and sharing center" and then there is the ALFA one that you can click on and it takes you to the ALFA wireless LAN utility, where you can also get a list of available networks.According to windows there is a problem with the connection, however according to the ALFA wireless LAN utility, the connection is fine (green bars means good connection, red bars means no connection)When clicking on the Windows "signal strength indicator" in the system tray, it shows 1 of 2 different problems (notice the differences that I've highlighted with red boxes). No matter which one happens I can NOT access the internet. Despite the "problems" shown above, the ALFA wireless LAN utility shows that its still connected (while windows is showing a connection problem)To reconnect I switch to the "profile" tab (which is just a list of neworks that i've previously connected to) and double click on the network. In this case it will be Enotria Public.... the same one that (according to the ALFA wireless LAN utility) I'm already connected too After clicking on the network, the ALFA wireless LAN utility "signal indicator" in the system tray will briefly turn red (signaling NO connection) while it "reconnects". Then it will turn back to green, and Windows network manager/signal indicator (whatever you call it) will proceed to reconnect as well. After this happens, all is good and I'm reconnected and can access the internet.
As you can see in pics above the ALFA wireless LAN utility is always connected, and it never drops the connection but even so, the internet will not work when Windows drops the connection. However, When reconnecting I can access the internet BEFORE Windows reconnects. (I still have to reconnect as described above, but after I do so I can access the internet before windows FINISHES reconnecting) The tab shown in this picture was a web page that I loaded BEFORE Windows ever reconnected, and it is a page that I have NEVER viewed before, so its not just loading it from cache.

ISP - Comcast Cable Internet Modem model SMCD3GNV wired/wireless combo (2 pcs connected 1 wired 1 wireless)When the connection is online, the speeds are fine- the issue is the 2-3 times a day when the connection drops off. The error that we are getting is "cannot connect with primary dns server" however in our attempts to restore the connection we have: [code] is there some issues in the area that we are not aware of? being that the signal levels are within range what do you think the problem resides in? FYI, both connections, the wired and wireless connections both have connectivity issues equally.

My computer is one that I built with windows vista, and for the wireless connection I am using a USB adaptor. I am not too sure what other info I need to put here.My connection used to drop frequently (around every 5 min) and I would have really slow speeds (10ish kb/s). Recently, for some unknown reason, the dropping has stopped, but now I am getting speeds of around 9-15 kb/s.
The thing that has me COMPLETELY stumped is when I plug my laptop into the router, the wireless speed on my PC speeds up to, according to speedtest.net, 5.8 Mbps. If I unplug the laptop from the router,the speed on my PC slows down to .25 Mbps, yes - POINT .25 Mbps.I have attached the tester .

I've been having a number of issues with performance on my DIR-655 with streaming media, internet connection being dropped and random reboots. Over the last couple of weeks it has been getting worse, to the point where I'm about to act out the printer scene from Office Space but with my DIR-655! It has been rebooting, completely killing WiFi networks and Internet Connection, almost every 20 minutes when I'm watching DivX over the network. The relevent information about my network is as follows:
-Hardware:
-D-Link DIR-655
-Hardware Version: A3 (US) , Firmware Version: 1.34NA
As an experiment I reconfigured the DSL-380T into PPPOE mode and set the DIR-655 into DHCP Client. This was over 2 hrs ago. So far - no random reboots, no jittering on the Media Center Extender playing videos, no internet drop outs..It seems to me that the DIR-655 doesn't cope well when it has to do the PPPOE network protocol as well as the routing, WiFi and other basic functionality that it should be able to cope with.I'll leave it running as it now is and report back later, but from the dramatic change in behavior I'm hoping that I've finally cracked my perf issues with the DIR-655.
