Hi
I have an issue that I cannot seem to work out, wondering if anyone has experienced this before. We have an ADSL2+ line from a WIC in a 1841, everything has been fine for the last few years and then the last few months the connection going down. When checking the interfaces the ATM0/0/0 is up up and the same for the dialer interface we are using, they are both up/up, but this still needs a reload of the router to be functional again, shutting the interfaces does not bring the connection back up.
I am not an expert on ADSL lines, I have never really had a problem with anything previously. The router was running Netflow to a network monitor wondering if this or logging was causing an issue with entries in the buffer??
Here is an output of show dsl int, would anyone recommend changing the firmware, it has been fine all this time before though we are running IOS 12.4(24)T1 advseck9-m, as far as I can seen from our ISP the config for ADSL is all correct, completely stumped if anyone has any ideas that would be amazing!!
Thanks

You should try updating firmware, however you also have high attenuation, check if telco can move you to a different pair.

Thanks for the advice I will give the firmware a try. I will mention the high attenuation see what they say, that is something I would not have picked up on.
I know this sounds stupid but does anyone know where the firmware is, so far I have had no luck finding it with our Cisco login, searching for our HWIC-1ADSL, I did read firmware can be stored in the IOS, is this correct I can't remember if this was just for an 800 series router? Looking up the Router under downloads certainly doesnt seem to display the correct WAN Interfaces for ADSL WIC.
Thanks again

Firmware is under 877 downloads, but a support contract is needed for downloads.
It was also on a public ftp before, now it seems that is gone also.

Many thanks will give this ago our contract will get us access to that firmware.
Thank you gives me some things to look into!
