Since the summer break, we are losing the main internet connection increasingly often. The Experia10A box goes to red, and after 30-60 seconds it switches back to green (no other colors in between). Wifi keeps working, but there is no connection to the internet during such an event.
The TV is also losing connection (303 error code) lately, need to switch off & on the unit to get back to watching.
Working from home (telecons and videocons) is really getting hampered by the frequent losses. Earlier we had a very stable connection, also thanks to the glass fiber optic setup.
I have tried to restart/reset the modem, it does not seem to make any difference. The DSL link is down (not sure if this is per design or a symptom).
Any ideas what can be done to stabilize the internet connection?
