Mac OS X traceroute not even reaching router gateway
I am on M1 Cable (residential) broadband in Singapore.
I have an intermittent problem routing to some sites from my MacBook Pro—often Google-related sites (arduino.googlecode.com and ajax.googleapis.com right now, but sometimes even gmail.com.) This prevents StackExchange chat from working, for instance. Funny thing is, my iPad can route to those sites and they're on the same wireless network! I can ping the sites, but not traceroute to them which I find odd.
That I can get through via the iPad implies the problem is with the MBP. In any case, calling M1 support is... not helpful.
I get the same behaviour when I bypass the Airport Express entirely and plug the MBP directly into the cable modem. Can anybody explain a) how this is even possible and b) how to fix it?

The traceroute from the iPad goes (and I'm copying this by hand):
10.0.1.1 184.108.40.206 172.20.8.222 172.31.253.11 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52
From the MBP, I can't traceroute to any of the IPs from
