Cisco 877 ATM interface "hangs"

I have a number of 877 routers used for ADSL backup, intermittently the ATM interface hangs cannot access the internet at all, the only way to start the ATM again is to do a "Clear int atm0" command

the Versions of IOS running are ADVSECURITY 124-4.T3, 124-6.T6 , and 124-6.T7

relevenent part of config below

Re: Cisco 877 ATM interface "hangs"

Hi, please upgrade ADSL firmware:

ftp://ftp.cisco.com/pub/access/800

The one you want is 3.0.x, there is a doc on how to install it.

Hope this helps, please rate post if it does!

Ok . I had started to download later IOS anyway, but just upgrading the firmware saves a bit of time
