DSL 2730B - Intermittent Ping Timeouts To Router
Oct 19, 2011
I have been having trouble with my DSL-2730B router. I am running a home network with a wired desktop connected via ethernet, two laptops, one desktop and three ipods connected wirelessly to the router.The problem is that at seemingly random times during the day the ability to connect to the internet is lost on all devices (wired or no). I also often lose the ability to connect to the router's homepage (settings) and upon inspection have found that when I ping the router I get time-outs (or sometimes destination host unreachable). This occurs on both wired and wireless at the same time and usually lasts anywhere from 10seconds to 10minutes at a time. I have reset the router numerous times including a reset via the web browser, unplugging the router and reconnecting and also have done a factory reset to attempt to solve the problem - all to no avail. As I am writing this I am using a different older router that so far (as of an hour) has not had the same issues.I should also mention that this happens regardless of which devices are currently on the network. I have had this problem with the wired-connection by itself and with my wireless laptop by itself.

I have a router that needs to be reset to get the internet speed back to a usable speed. It is a fairly old router (D-LINK DSL 2730B) and it does get quite annoying. There is allot of devices connected, which may affect the speed, but I am sure it shouldn't change upon reboot. I literally reboot every hour or 2 during peek periods.

So I recently purchased an E4200 to replace my aging and slightly ailing DLink DIR-655 which as served me well for going on 5 years. The part of the DLink that was giving me the issues was the wireless, the routing and switching worked fine however.
I do quite a lot of streaming of media from my home machine outside my network through the internet. Most recently I've been using Kalemsoft Media Streamer on my HP Touchpad, however I've used Zumocast, Windows Live, Splashtop, and a few others. I havent yet tried my PPTP VPN through the router for an extended period of time to see if it reflects this issue as well though.
Since replacing my 655 with the E4200 I've started experiencing a timeout issue. It seems to be semi-consistant and only happens after time of unuse or extended use (I havent timed it yet to see if it always happens after the same amount of time though).
Basically what occurs is this:
I'll be watching some video or listening to audio streaming from my machine and after a period of time (usually a long period of time) it'll suddenly lose connection, requiring me to re-connect through the software, like the NAT translation is timing out or something.
How it USED to work is this: It'd basically work until I stopped streaming.
My setup:
AT&T Uverse set to DMZPlus aiming towards my E4200 WAN port (sitting directly in place of the 655 I used to have)
All machines on the network are gigabit. I have ports 7000 and 7001 open for Kalemsoft Media Streamer on the E4200 per the specifications of the software.
The software understands UPnP so I have nothing specific forwarded on my machine, but I didnt previously either.

I've got an aol engineer visiting Thurs.to examine connection loss (since last Weds). But I'm convinced the problem is with the router. But from the tone of the aol tech questions I suspect he's already briefed his engineer to do his best to represent the problem as being either with my computer or positioning of router/filters/condition of wall-sockets - usual getouts.The talktalk router is neww, issued Feb 12, after my original router, speedtouch, started suffering idle timeouts every day.

I'm trying to connect to an SMTP server using telnet via putty. Not just well known domains such as bigstring, aol, gmail, hotmail etc but also endless amount of not known or not popular ones.The problem is that although nmap says that port 25 is open, I can not establish any connection to ANY SMTP server (it just timeouts).I have tried disabling my firewall and using a proxy, but it still doesn't connect and now I've ran out of ideas. I also tried to disable my avast as well as legally used ip switcher program to make sure the problem is totally independent from my ISP.

I am using this wireless router for connection to internet:http:/[url]...The problem is that in most of the time the router works without a problem then suddenly without doing anything from my side the internet connection starts intermittent and then I can’t event connect to the router. This is a screenshot of pinging the router when the problem occurs.

I am tyring to remotely diagnose a troublesome ASA5505
It is connecting via PPPOE and the original suscpicion was that the PPPOE was going down during heavy loads during the day, i.e 9am and lunchtime. I suspected MTU and have verified the MTU outside is set to 1492
However further troubleshooting doing a remote ping to the PPPOE address indicates that this does not drop at all.
When remoteley connected to the ASA my session dies and any outbound internet fails, then in a few minutes it comes back.
all the time the PPPOE line stays up?
One thought is that although the line does not go down it is being crippled with traffic and just getting so unresponsive it appears it has died.

We recently got a 10 meg dedicated internet fiber connection installed. I connected it to a PIX 501 firewall and everything worked fine (I tested it for a couple of weeks). A couple of days ago I got a new ASA 5505 and replaced the PIX with this device. It works, but every so often there seems to be a timeout when surfing the web whereby I click on a link and there is up to a 45 second wait and then the page loads quickly. I was not getting this before on the PIX so I'm assuming it's not a latency issue with the connection. I am the only one using this connection on the network so it's not to say that it's being bogged down. I want to roll this out to the other users on the network but not when this is happening. The configuration is below:
: Saved
:
ASA Version 8.2(1)
!
hostname ciscoasa

I have a Compaq with XP wired on a Network with a Belkin N600 Router.There are 5 computers on the Network, (4 wired, one wireless) and this is the only computer that I have problems with connectivity. It connects to the Belkin through 2 switches.Typically when I turn the system on it connects, downloads mail, etc. After a short period of time there is no connectivity to the network for printing nor the internet.I may get connectivity randomly again after a while, but you never know if or when you will get connectivity again for sure. I am using Explorer.I had loaded some Belkin software with no luck so I uninstalled it. The other computers have no special software for the router.

[code] 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?

I'm being kicked off my VPN connection back to the home office on occasion, using a Nortel VPN client. The logs show:
4/2/2013 9:58:26.883 [ENGS] -I-VerifyServerIsAlive: ISAKMP had traffic (after keepalive).
4/2/2013 9:58:27.383 [ENGS] -I-VerifyServerIsAlive: Set receivedData FALSE.
4/2/2013 9:58:28.555 [ENGS] -I-Protocol not recognized - message dropped.
4/2/2013 9:58:44.586 [ENGS] -I-Protocol not recognized - message dropped.
[code]....
the common fault seems to be DynamicDnsCleanup causing the trouble.(causes routing table to change, knocking down the VPN....) Is this a function occurring in the router? I can't find search results showing so.

I got a Problem on a customer which is using a Failover ASA 5510 pair with SSM-CSC-10-K9 modules.The clients have to connect to a webserver where they are doing some calculations.If they prepare everything and want to calculate everything what takes a couple of time the session is after about 3 minutes timedout.My first idea was to set session specific timeouts which are a bit longer then the normal but this setting did not work. I created a policy which did not work for me. How to set connection specific timeout's? [code]

I have a web cache server, and I redirect all the HTTP request to it using WCCP.
Everything works without a problem, however I have a monitoring system that every minute tests the access to some customer sites that are hosted inside our infra-strutcture.
As soon as I configured the WCCP the monitoring system complains of timeouts accessing those sites, about 20% of the requests start to fail (timeout).
I don't think it is the fault of the cache because in the WCCP ACL I exclude all traffic that comes from my monitoring system. However as soon as I turn of WCCP the monitoring system never ever gives timeouts accessing those sites.
Is there anything I should do in WCCP to tweak it? I have WCCP configured in my core gateway that is a CISCO 3750.

I recently updated the firmware in my WRT160N V3.Ever since, the wireless signal is intermittent.It worked all day yesterday, and now today it doesn't connect at all.I can't remember exactly the settings I used to have before updating the firmware, should have written them down.From looking at articles on this site, I have the following settings:
MTU Manual 1492
MAC Adress enabled
Network Mode: Mixed

I have a WRT120N router set up with WPA2 security and set to channel 11. Everything is connected via the router (one wired computer, up to a max of 5 laptops but just 2-3 on a regular basis, a wired xbox360, wireless wii and a few cell phones occasionally connect wirelessly). Everything has been working great, been getting at or very close to the 6mbps we are supposed to be getting...until the past 2 weeks. Suddenly the connection drops repeatedly throughout the night. It either shows local only or just "limited connectivity". Normally when this happens my laptop will pick the signal back up when things are normal but I am actually having to disconnect and reconnect for it to work again. It happens again in about 30 min to an hour after that. Also, our connection speeds are showing at .5 - 1.5 instead of 6. I plugged the cable modem (the 660 series sent out by sprint/embarq/century link (or whatever name they are going by today lol) into the computer directly and got 5.7mbps. I have tried power cycles of both pieces of equipment but that doesnt work.

My router has been dropping the internet connection for years. The ethernet connection to the desktop works fine all the time. The problem is only with the wireless connection. About every 1/2 hour or so the router will drop the wireless connection and neither or my 2 laptops can find the network. Unplugging the router and replugging it in solves the problem temporarily, until it drops it again. I updated the firmware to 1.0.4 and that yielded no changes.
Router: WRT54G2 v.1 Modem: Siemens Speedster 4100 (part #060-D141-A12) My two laptops running wirelessly are Macs. The desktop is PC running Windows Vista.

Bought an E4200 to replace my Netwgear router and am experiencing the following problem.One of my wireless boxes serves as mu mail server. I've been running this configuration for years so the only thing that has changed is the router.The neworkd is up and all wireless clients can connect, but after some time, access to the mail server just 'freezes'. I say freezes as the nework icon (i'm using ubuntu' still show a connection. In addtion, there are not error in any of the logs. I just seems that the mail server and the router just stopped communication.

Im running 8.3 on a 5505. We've got a few ssh tunnels originating from inside to some place on the internet. It seems these tunnels are closed every n minutes. I've seen two recommendations for altering the timeout values, and what I am interested in is infinite timeout (0) for these SSH tunnels.
Suggestion 1, alter timeout "conn". Default is 30 minutes, but I suspect this might have a negative impact because no inactive connections would be closed, ever. If it however is recommended to alter, how to set it to "0" (off/unlimited)? timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02
Suggestion 2, enable a ssh class map which explicitely set the timeout for the ssh connection. Is this recommended? How would I achieve unlimited time? And what about random-sequence-number disabled as seen below, is that really recommended?
class CLASS_MAP_SSH
set connection random-sequence-number disable
set connection timeout idle 48:00:00 reset
set connection decrement-ttl

We have recently put in a new 2901 router to be our IPSLA router and after adding 430 operations to it (215 ICMP and 215 UDP jitter) to cover off our state wide sites, it's reporting over half of them as timing out. Over the day, the timed out operations change so that our monitoring system shows the operations as down most of the time and up or warning state the rest of the time.
Some of the remote routers are reporting "SLA_FORMAT_FAIL" errors but I cannot find any references to this error.A ping from the router to the remote site router returns a ping time of 50ms or less and the network links are not conjested so QoS shouldn't be getting in the way. Our QoS policies would mark and prioritise the UDP jitter test traffic and the ICMP would be in the default class.
The 2901 is running 15.2(4)M1 and has 512MB RAM and 256MB flash. It's single homed into our core network switch. I've heard stories of 2900 series routers hosting 1000's of operations so I don't think we're taxing the router. CPU is sitting around 5% and memory is around 20%.
Below bits are for one set of operations.
*******************************************************************************************

I have been having a problem with my router for the past two weeks and my ISP (RCN) has done nothing to fix it so maybe with our nerd power combined we can find a solution!My router runs fine about 60% of the time, I get 20-24Mbps down and 2Mbps up connect wirelessly. the other 40% of the time the download speed suddenly drops to 1.5-2Mbps down and 1Mbps up. There is nothing in particular that I will be doing at the moment it just suddenly dies.Things I have done that have not worked.I have changed my channel to 1,6,and 11.Updated firmware.Factory Reset (New broadcast name/password).Set up static IPs.I have tried disabling WMM Support and this just kills any connection wirelessly to the router.Is there anything else you can think of to fix the issue, or should I just be demanding a new router the next time they come

I recently upgraded my Linksys wrt120n router firmware & had to reconfigure settings. Subsequently, some (but not all) of my apple devices are having intermittent wireless connection problems. Specifically, my ipad1 & ipad2 never lose their connection but a mac book pro (~ 2 years old), iPhone 3g, iPhone 4, older iPod touch & very old i book g4 all work for a period of time (usually 1/2 day) & then lose their connection. When I attempt to reconnect these devices I receive the following error..."unable to join the network xxxxxx....". I also have a Dell laptop (1 1/2 yrs old) that generally does not have the connection problem. Finally, when the devices do lose their network connection all I have to do to reconnect is go to the Linkys router setup webpage & click on save & the wireless connection works again (almost like this is just refreshing the connection for these specific apple devices). I was not having any problem prior to the firmware upgrade & from what I have read the older firmware version is no longer available so going back to the old firmware does not appear to be an option.

I have set up a new wireless network for a customer and they want to use the guest portal for som users.The problem that I am expering is that on a particular site with many small buildings user complains that they have to reauthenticate using the webportal when moving between the buildnings. I have tired extending the idle user timeout on that particular wlan in the cisco 5508, but I still having this problem.
I would actually like if the user login via the guestportal at the beginning of the work day and after say 4-5 hours they have to reautencitcate.And if they loose network connectivity (moving between buildings, iphone/andriod shutting down wifi adapter, etc) they shuld be fine connecting again because they have aldready authecnticated once during the last 4-5 hours.
Is this possible via the ISE?My second question deals with 2.4 and 5 Ghz band.I use AP groups on each of my distribution areas. All groups have the same SSID but diffrenet egress interfaces (interfaces groups). And in some of these I want to save the 5 GHz band for voice over wlan and in others i would like to use both bands.
Do I have to create diffrent wlan profiles with diffrent radio policys and same SSID or could I do this in the AP group settings using RF-profiles?

Just recently we replaced our HQ Cisco-Pix with Cisco-ASA 5510. where we have many branches connecting to our HQ through site-to-site vpn.
Since putting this new ASA5510 at HQ , while we are getting a Remote-Desktop session into our branches clients, and at the time when even a single TIMEOUT occurs on the vpn-link so the remote-desktop session gets completly lost. then we have to re-connect the session.
This issue happens as i said above when a single timeout occurs on the vpn link. What is the issue with the ASA5510. because with pix we didnt have this issue, remote-desktops were never geting lost / reset with single timeout

We're getting "Connaction Timeout / Connection Failure" error messages several time per day. Here is our setup:
Verizon FiOS Internet (ONT Box) --> Cisco ASA 5505 --> EdgeMarc 4500 Router --> Cisco 300-24G Switch --> Dell PE1950 Servers
From past few months, we keep getting Connection Timeout and Connection Failure error messages in our vendor application which connects to SQL Server 2005. Also Terminal Server 2003 keep disconnecting for every few hours.After several days of troubleshooting, we come to know that this Cisco ASA 5500 is not working properly. When I access the ASDM, it shows several warning messages.I know there is a setting option to configure TimeOut, but is there anyway to test and track the ASA 5500 regarding this Timeout issues?

I have reason to be suspicious as to the game's relevance. These spikes are characterized by no packet loss, as measured by pingplotter and winmtr (more specifically, there is packet loss, but I've come to understand that because it does not continue on to subsequent jumps it's not an issue), and latency leaping to between 250 and 600ms across multiple hops, seemingly without pattern or form, for intervals
Here are some summaries of some extended pingplotter sessions. The suspicion that this is not entirely WoW related is recent, so I'm working on seeing if I can get similar results from some other sources.
