cannot access web interface

[allsorts]

In theory the Avast problem is fixed from Avast program version: 17.5.2302 (build 17.5.3559.0). This was released at the begining of June. I say "in theory" as I'm having trouble with Firefox and the signals display freezing aftera few tens of seconds, the clock stops, changing pages doesn't happen, eventually the controller reboots and everything is alright for a while. I shall disable Avast's webshield and see if things get better.
