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
