If he puts you on a 7330, it may solve your issue. But If you stay on a stinger, the only way to "fix" it seems to be a IPTV profile.

It won't, same thing happens on 7330s unfortunately.

Changing the MTU might be a temp fix, but there's still an underlying issue with either the firmware, or the chipset itself.

You've heard of people on 7330 having this issue ? As far as I remember, I didn't had any issue when switched to a 7330.

FWIW, I monitored two sites for several days, one 7330 and one IKNS, for ICMP packet-length sensitivity. The results were similar.

It would be helpful to get more clarity on questions such as:

1. Which hardware is affected? -- 7330 and/or IKNS
2. What symptoms can we measure when the problem state is acute? -- can ping (reference host), but cannot do (what exactly).
3. What symptoms can we measure when the problem state is not yet acute? -- can ping short packets (eg 84) but not longer packets (eg 85) to reference hosts.
4. What interventions end the problem state? -- resync, but not re-PPP.
5. What fixes are known? -- IPTV or Interleaved.
6. What is known about the failure mechanism? -- MTU? Timing? Software "side-effect" errors?
7. How can the problem state be produced, easily, quickly, reliably?
8. Rigorously confirmed, reproducible, documented data on the above.

All of the above are perfectly amenable to collaborative efforts.

Yup. My friend (also a Bell tech) just did his own 50/10 install and was having the same sync-no-surf issues. He gave himself a FibeTV profile and it hasn't happened since.

There is a regular vdsl interleaved profile without having to use a fibetv interleaved profile. Interleaved profiles will reroute packets the are dropping and solve the sync no surf issue but interleaved isn't a fix all solution when there is a physical problem causing the packets to be dropped or lost. But it would probably fix your problem for now.
