We have a fairly major problem with some of our Cisco 877 units (5 in all). All are running 15.2(2)T2 in order to make use of zone-based firewalls and virtual reassembly, and all are exhibiting the same problem. When our ADSL line drops this si shown in syslog

The "no retrain. sleep 20 seconds" messages continue forever more until somebody power-cycles the router - which is a bit inconvenient as two are 300 miles away. Surprisingly, our event manager applet isn't triggering the reload either, which defeats the object.
i have a problem with my adsl line connected on a HWIC-ADSL on router 2901 it was working good until yesterday the atm interface is down but the interface dialer is up .i connected this line into home adsl modem and the line is working good?
ADSL line do not activate. Telco Confirmed Like is Okay . They have tested no issue observed. Router replaced but did not work. Supspecting Firmware not compatible with telco . Not sure how to confirm on this.

Site A, site B, site C, site D is connected using leased line each other. We are using Cisco 1800, 2800 and 2900. Each site also have Internet connection using ADSL connected to firewall, we are using pix 501 and ASA 5510.My question is, can i use the existing ADSL line to be use as a backup line if the leased line is down on any of the site??
And i want it to trigger itself, once the leased line is down, the firewall UP the backup line? something like that..
I have D-link 2640U ADSL2+ modem. Now I have 12Mbps / 1Mbps internet connection. I am planning to move to 24Mbps /1Mbps intenet connection and I want to know if this modem is enough. What is the best modem so I get the full 24Mbps[CODE]
Is there a way to find in a remote branch the adsl line number in a cisco router 886VA.
When giving show controllers vdsl 0
we can see the upload/download speed but there is no information about the line number. We need this information in order to troubleshoot adsl line problems with our ISP's in remote branch offices.
I do have a question, is WIC-1SHDSL-V3 able to support ADSL line?
We have WIC-1SHDSL-V3 module used for SDSL line, due to few site need to bring up with ADSL line with 1841 model, but HWIC-1ADSL module already EOS. The replacement model EHWIC-VA-DSL-A is not compatible to 1841. My architect suggest Symmetric Module like WIC-1SHDSL-V3 could be able to tweak the config to support Asymmetric purpose. I did google but do not found such related topic. Can any expert on this area to advice me?
Our church has 1 phone line, we run BTBusiness Broadband at one of the building where we have a couple of charities based. We have the phone line connected to an extension at the other end (where the Church is) >80m away. Any way of running a second concurrent router on the extension so I can set up an office with a VOIP number, pC's printers etc there too? We use Devolo ethernet over mains and wireless for the main building, but the church itself is on a completely seperate mains power supply so I can't use that. I could run 100m Cat 5 and locate a switch on that, but any way of achieving something similar over the phone cable which is already in place.
Can I install 2 ADSL routers on one telephone line with SKY. If I can does this mean that if sky give me 20mb connection, I can get two lots of 20mb using the two routers.
I have a broadband router (Linksys E1000) which I've flashed with a DD-WRT firmware. After doing so I realized that this router doesn't have an interface for ADSL port(RJ-11). How can I use the Linksys E1000 for my home network?
I've heard that I can use ADSL modem(not a router) & plug the RJ-11 to it & take from it the Ethernet & plug it back to the E1000(in the WAN port) would that mean that I can get just a modem and not a hybrid?
Note: Also, I have to mention that my ISP is using PPPoA & DD-WRT is not supporting it, but i googled & they said that the ADSL modem cab be the rescue. Can I pick any ADSL modem for this specific scenario or am I looking at a specific model?
Secondly, can I use my old router to do the job instead of buying a new ADSL modem ? & is it a good approach ? or should i buy a new ADSL modem ?
Update i turned my DD-WRT router(E1000) to act as access point, since this is the only way that i can use it with the DD-WRT feature. & i think this is better than have nothing :) I can now have the DD-WRT functions ;)
I have ADSL router Linksys X3000, but I have an issue with it. I have configured it properly (based on internet provider's manual), repeatedly checked it, but router still says that ADSL line is down. I have also another router from Zyxel and it works perfect with same wire and configuration, so I guess the line is fine.

Is the ADSL line interface on Cisco 877W not initialising a known issue? This interface on my router has been in this state for more than one month, with the rest of the router seemingly operational. The interface was connected directly to my ADSL broadband and worked well for two years. But then, about a month ago, the interface went down. I saw the exact moment this happened recorded as a syslog message. The only information was that the interface status had changed to down.
Initially I thought this was a matter of reload the router and all will be well. Did not happen. Then I thought my broadband connection was to blame. However, this option was quickly ruled out. So I went on to exhaust all troubleshooting options, including reflashing the router with the saved image and totally changing the configuration. Still no change. I have had to go back to my old BT home hub for internet access. In terms of speed this actually works a lot better than the Cisco router. But I would still rather have the router connected to my broadband line. What can I do to bring the ADSL interface back to life?
On my old router I could access the line stats on the home page giving me Attenuation and SNR margin, this allowed me to keep an eye on line quality, there seems to be no equivalent info on the X2000. Is this on a hidden page like the advanced wireless page.

Within a property without an available adsl line I'm simply trying to network a wireless laptop with a wireless printer. Both devices recognise the router, etc, but problem sending file for printing to the printer. (laptop does not detect printer). Is the lack of an internet connection the issue or simply a configuration issue?
We have a remote site connected to ADSL line with a Cisco 887VA router attached. This has been working fine for the last couple of months. However, recently, the site have started to complain of performance issues (network slow, applications disconnecting, etc)Looking on the router, we can see evidence of packet loss/timeouts from a simple ping to the internet e.g. [code]
However, we have logged the fault with our service provider and they return all line tests as clear but what is particularly strange is that they also report “and the SNR Margins are well within threshold levels (Upstream 11.5 and Downstream 15.0)” which, unless I’m misunderstanding something, seems to be completely different from what the router itself is reporting.Is there a reason why the service provider’s stats for Noise Margin would appear to be so different from what the router is reporting?
I've moved a Cisco 887 router from a site where it was used to dial up on an ADSL line to a new site where we have a EFM circuit which terminates at a Cisco 1841 router managed by our ISP. I therefore need to re-configure our 887 router to work as a conduit from our servers back to the Cisco 1841 as its gateway.
I have asked from our ISP and they told me that i need to configure the 887 to use IP address 176.35.140.65 255.255.255.248 and its gateway should be 176.35.140.70. That's great advice in theory but I don't know how to configure this correctly
Our internal network is using subnet 192.168.42.XX which will need to be retained for local devices.
I can connect to my router but not to Internet, it seams that ADSL line "disconnects" my LAN/WLAN this issue is with Inalambrico 6867R router an other router, TP-Link is working great
I have bought a WAG320 & ever since I've had it the ADSL line keeps dropping every few hours. The LAN network is fine & I have 7 computers connected to the router wirelessly. When I press the re-set button on the back of the router everything is fine for a few hours then it starts doing it again?
I have been using a Cisco 877 router at home for more than a year and I've always been quite happy with it, but I've stumbled upon a very strange issue after an IOS update. I was using IOS 15.0(1)M until last week, when I decided to configure the router as a VIN server (both for PPTP and L2TP/IPSEC) in order to be able to connect to my home network from outside; then I realized that IOS has a nasty bug on PPTP VPNs (it just ignores the ppp encrypt mppe auto instruction), so I updated it to the latest 15.1 release I could find, 15.1(3)T1. Everything worked.
Until I launched E mule with some heavy download, and the connection dropped. And didn't come up again, even after a clear interface ATM 0: only rebooting the router solved the problem. Which, upon launching E mule again, again happened. The problem seems to be related to opening lots of connections at the same time; "simple" heavy load (like downloading a big file at full speed) doesn't do any harm to the line, and configuring E mule to use a smaller number of connections and opening it more slowly seems to mitigate the problem, which anyway keeps happening after a while.
The strangest thing is, this is definitely related to the IOS version. It didn't happen before the upgrade, and I confirmed it stops happening if I reload the previous IOS on the router. Out of curiosity, I also tested some other IOS releases: 15.1(1)T, 15.0(1)M5 and even 12.4(24)T5. It always happens, only 15.0(1)M seems to prevent it... but it also seems to hate VPN encryption. And let's not even start talking about 15.1(4)M: I tried it and I wasn't ever able to successfully authenticate a VPN connection. Of course, when tried different IOS releases, the router's configuration always stayed the same. Here is it (stripped of personal details):
no service pad service timestamps debug date time local time service timestamps log date time local time service password-encryption!host name [Code] ....
How can I fix this without reloading the buggy IOS I was using before? If you need any debug information, feel free to ask and I'll provide it. This is the current show version:

DSL: Training log buffer capability is not enabled. Also, any suggestion at fine-tuning the router; I can currently reach 7M/512K top speed, on a very stable line.
[code] My connection is ADSL with 2Mbps broadband. Using speedtest.net for testing the speed I got almost 2Mbps, that is ok, but this is connected directly to the modem. The problem is when I use the router, when I connect it the speed downs onward until it achieve a stable value of 512kbps, that is 4 times less than my contracted speed. I have tried with four different D-Link routers (DIR-280, DIR-600, DIR-600 N150, DIR-615), four ones give the same problem.D-Link tech support people don't have idea about what is happening just like tech support people from my Internet provider. I think the problem is not the modem because I get 2Mbps from it connected directly (without the router).I do the speed test in an interval of 3 minutes between each test, with just one device connected and only doing the speed test, all programs that use Internet access are closed.
Always is the same, after a time the speed drops down, from 2Mbps until 512kbps. The router has the QoS disabled, I have tried changing the MTU value, I have tried some values 1492 (this is the official from the Internet provider), also I have tried some lower numbers 1400, 1200 but the result is the same. The router has as security only wpa2 and it has a static public IP, the modem is configured as bridge. I have also tried unplugging the phones, connected to the splitter, keeping away the wireless phones, moving away the router from the modem for electronic interference, modifying the WAN speed from auto to 10 and 100, I have disabled the firewall, change the channels and power TX. I do the speed tests using the wireless and wired interfaces.
The reason is i want to know the difference between the leased line and the DSL line. The whole thing behind the confusion is, We plan to have a high speed internet connection in our office. We will don't have a branch office or some thing like that. I preffered to have high speed internet in our office. I found in some website that Lease line will have high speed connectivity(Upto 10Gbps). Can i use the lease line or DSL is enough for our office. Our office contains of 82 user who will use internet.
One of my branch offices is connected to an ADSL line as well as a VDSL line.Since I really don't need the ADSL line I came up with the idea to use it as a backup line.So I searched google and found this nice little article URL. I wonder if the router will switch back to the primary ISP if the primary line comes up again?
I was working on a problem the other day and came across something that I had seen before but never given much thought. I had a router with a switch connected to it and the interface was showing as Ethernet0 is up, line protocol is down. The problem in the end turned out to be a cable that had fell out because it was not connected correctly, but I was able to replicate this interface status on a router (FastEthernet0/0 is up, line protocol is down), and NO cable was attached to the interface.I've had a look on the internet but cant seem to find a good answer, so does anybody else know why this status is shown on the router? Remember, NO cable is connected to the interface so it isn't a speed or duplex problem
I ran across this today on a 7200 that when all the vty lines are filled, and dont release, you enter clear line vty x and it is supposed to release the line. Well in some versions it doesn't work.
Here is the work around I found. clear tcp line vty x
how to bring this interface back up? It's a 1252 with 80211.n.I started configuring it with CLI and then was using the web interface. I made a change on the web interface and it caused the AP to hang. I rebooted it and can access via Hyperterminal, but I cannot ping the IP address nor bring it up in the web interface any longer.I tried the "No shut" command in the BVI1 interface.
we have one OC-24 private line between our data centers. we are looking to get best throughput but we get max. avg throughput of 300Mbps with peaks of 800Mbps throughput. i.e. we transfered 2TB of data over this link and we got average throughput of 300Mbps with peaks of 800Mbps.
we should at least be getting 800Mbps throughput since we have OC-24 (1244Mbps) private line. we contacted our ISP but they said there isn't any problem in private line from ISP side. what can we do to increase average throughput?
I'm facing an issue since 2 month now , no one is able to tell me what's going on. The line goes down suddently for 2 or 3 minutes and this happens everyday at the same range (~2 or 3 hours) of time . I don't have any scheduled task to cause this. ISP in his side has also made some tshoot but found nothing and is convinced that the problem is coming from our side :
We have a barn that is quite a difference from the house and would like to add a router out there also, since all our animal sales are done from that point. We just have one phone line for the house and for the barn.
