Just over a week ago this forum helped to resolve a problem whereby a Cisco 857 could not connect to the internet following an upgrade to ADSL2+
The router was working fine, then dropped the connection. The router is no longer connecting, yet when it is swapped for a Netgear 834, it connects straight away.
Can anyone recommend any tests or settings I can check. Nothing has changed in the configuration, and as far as I know, nothing has changed on the ADSL line.
