Greetings,

Welcome back to the forum.

I am not a HP employee.

There are many different HP 255 products ranging from G1 to G7 Notebooks. 

80 packets sent and nothing back means you are not connecting to the network.

I don't know if this is a ethernet or WIFI problem.

You have multiple failure points.

The ISP

Ethernet or WIFI drivers

The modem

The router

You had a unknown update. Could you connect to the net before this update?

Your problem is very hard to diagnose.

Regards
