[TriLUG] Problem determination help needed

[David Both via TriLUG]

I have tried plugging the cable directly from the laptop directly into the 
NIC in the firewall/router. I still get about 350Mb/s. This takes any 
router issues out of the equation. However, since the router won't do more 
than 400Mb or so, I may just stop worrying about it.



Thanks for the response.
