I have connected a Cisco 857 router to an ADSL line. Internet worked for a while, then the connection started dropping. I have tested with a different router (a Netgear) and the connection is stable.
The line is adsl 2+, and I have loaded the latest firmware (adsl_alc_20190.3-0-33.bin) but this has not helped.
I ran the command "show dsl interface atm0" and have attached the results.
Can anyone advise what could be causing the problem?
