Re: Request for assistance with Verizon FIOS connection

[Matt Corallo <nanog () as397444 net>]

OP indicated they've tried both a direct laptop connection as well as another router. That seems to 
meet the requirement for having ruled out his home-made router, though obviously I agree one should 
attempt to rule out any possible errors by doing transparent packet sniffing analyzing the problem 
carefully before escalating an issue. Hopefully everyone on this list knows the value of the tech on 
the other end of the line's time :)
