Hello    

I really need HELP!


I have a Cisco1801 connected to ADSL. All was working fine but one day there was no more ADSL synchronisation !

I contact a lot of times my provider: no problem

I try with Cisco877, Speedtouch modem and Zyxel 660: ADSL sync OK

I try with 2 others 1801: no ADSL sync !!!

I upgrade IOS: no ADSL sync !!! c180x-advipservicesk9-mz 124-9.T4 to 124-11.XJ4 to 124-15.T13

I try to modif atm parameters: not better !!!


If somebody have the solution ...

Looks like you will need to upgrade your ADSL firmware. Would be easy if you have a contract with Cisco.
