    Hello everybody.
    I have this cisco modular 1721 router with a wic adsl card. I am on BT broadband. Everynow and again the connection just droops, I got now IP address asigned to my dialer1 interface and then it comes up after like 1 or 2 minutes. What I noticed also is that my router every now and again is rebooting itself and as I was just creatting another setup file for it next to the terminal window I saw it crashing and rebooting.
    This was the message I got:

    I'm no Cisco expert (at all!) but part of that message suggests that the part of flash that holds the crashinfo is full and needs clearing? If you did that you might get more info?

    Hello hbroomhall.
    You are right about the free space on my flash.
    I deleted all the crashinfo files and they do apear as deleted but it hasn't cleared any space on the flash.

    I'm not too familiar with the 1721 but I think you need to do a "squeeze flash:" to recover the deleted file space.

    I think the 'squeeze' command depends on the IOS, maybe..

    Judging by the contents of your flash, the router's been doing this since 2nd October?

    Try using the SDM, and see if anything crops up there?

    I just went straight to a erase flash ans nearlly lost it when getting my IOS restored back using rommon mode with the tftpdnld comand.
    Tooke ages just to realise that the minimum settings that we need like ip_address was just not working cause of the lowercase. Done it ussing UPERCASE IP_ADDRESS= and it worked go figur.
    Anyway guys bellow there is a screen of what now looks.
    The router hasn't yet crashed but lets see if it does it again. What I also noticed latelly is that my internet connection drops quite frequently for a while now even using BTs homehub, I wonder what's causing it. The phone line is noisy, it didn't use to be noisy but all tests performed by BT say that the line is free of errors.
    Internet is also slow since we got a call d#from BT asking us if we'd stay with them for another year and by doing so they would drop the price by £2.00, I think that not only they have dropped the price as they also dropped the speed.
    Thanks guys

    Sorry mate but could you please be more specific as I got no clue about what do you mean with the filter.
    Thanks

    On a DSL line you either have a filter built in to the faceplate from BT (the original and more reliable method of doing it)

    Or you have an inline filter, which is a little tailed adapter that you plug your DSL connection in to one port and the phone in to the other.

    if the phone line is being noisy it usually indicates either a failed/failing adapter (most common) or the standard BT faceplate is failing (happens rarely)

    Usually replacing the tailed inline filter corrects the problem

    Sorry mate but I was miles away from that, I thought you were talking IOS commands. I have totally misinterpreted your post.
    I have one inline that was already replaced when all this started and the line is still noisy.
    Can the noise be the cause for the router to crash?

    Ok... After a full reinstalation of the IOS image ( after erased the whole flash) my router still is crashing.
    Here's a more detailled information of the crashing file attached.
    It has crashed 3 times yesterday and 4 today.
    What is going on here? Is my router faulty? The thing is even my BT HomeHub is rebooting itself every so often as well. It all started around the same time, Is this a coinsidence?
    Thanks

    Have you tried booting it without the WIC to see what happens?

    Hello BosonMichael.
    I have taken the WIC card out and I am now using my old BT home hub for now.
    I will leave the router on all night and day tomorrow till I get back from work and then see what does happen.
    It took me quite a while to have this router setup to go online and it only started to crash when I managed to get it up and running online so it might be related. Also as I have said before, the line is a bit noisy and it didn't used to be like that. The weirdest thing is that even BT's home hub restarts itself every now and again.
    I can see while watching a movie all the lights all of the sudden flashing and you hear it click as if it just restarted.
    I'll keep you guys posted tomorrow.
    Much appreciated for all your help.
    Cheers,
    Albert, C

    Yes if it is really bad, I had a really noisey line once and I tried three different manufacturers before discovering the socket was at fault not the line, filter, or the equipment.

    I think there is another thread around here somewhere with a similar problem.

    I would check your master socket and any extensions

    Phone BT faults whilst you have noise on the telephone plugged in to the socket that way they can hear the noise as well and cannot dismiss it after a line test.

    You could try replacing the master phone socket if you have tried everything else

    Teebor,
    I guess it won't hurt buying a in wall built in adsl filter and have it put in place.
    I have had BT checking the line and they have found nothing, including one of CF members works for BT and he personally have done a line check and also found it to be ok but, I shall follow your comment.
    I will ring them. After all it does make sense the crashing as so their BT home hub also crashes.
    The router still hasn't crashed since yesterday as you can see bellow...

    One more question. Do routers come with a built in battery so that it can keep the time correct? Reason why is that my router is always falling behind on the time.
    I have purchased it on eBay brand new sealed in the CISCO box with the Cisco approved seal hologram sort of thing.

    Cheers mate,

    Most things usually loose time one way or another (look at windows PC's)

    Best thing to do would be to google search for "public NTP server" and then use the NTP command on your router from config mode to set a server. When connected to the internet the router should then make sure its time is correct

    If it is of a concern to you and want to set it that is

    As for the NTP command mate my router’s IOS don't have it. Not to worry much I just thought that the router would have a battery sort of thing.

    I am now going to insert the wic card into the router again but in the other bay and see what happens.

    Thanks everybody.
    I'll keep you all posted.

    Thanks mate.

    Anyways, just after a good night sleep here I am just to find out that my cisco router 1721 has crashed yet again. I must say that it has only crashed once on the other WIC1 slot which is rather less than than the other WIC0 but this might be just coincidence.
    What to do? I am lost.
    It is a nightmare when your accessing your bank account or any online secure server and all of the sudden your internet connection drops.
    Anyone, anymore ideias?
    What can be done?
    Cheers everybody.

    It might be worthwhile posting the running config ( blank out your IPs and passwords ). I found some references on the Cisco website to crashes in similar routers caused by QoS commands.
