Hi,

Try this, I believe the upgrade strips out some firewall settings that maybe crucial for the browsing the internet.

Got to Settings → Tools → Firewall - > Customize → Packet Rules

Make sure you have the following entries.

PING OUT - Allow - ICMP(1) - Out - ICMP Type 8
Traceroute OUT - Allow - ICMP(1) - Out - ICMP Type 30
PING IN - Allow - ICMP(1) - In - ICMP Type 8
Traceroute IN - Allow - ICMP(1) - In - ICMP Type 30

Make sure they are enabled
Click OK

Test connection :wink:
