Re: Slow Cable Modem

Which sites are slow? I recently read somethign about 2.4 having
compatibility issues with certain routers.

For more info, see this link.

The long and short of it is try:
#echo "0" > /proc/sys/net/ipv4/tcp_ecn 

and see if it helps. 2.4 implements something called Explicit Congestion
Notification, or ECN. It's a good idea, but some routers have not bee
upgraded to support it yet. From one of our network engineers:

   PIX and LocalDirector have been the main culprits with ECN issues, as far
   as Cisco gear is concerned.

   ECN support for PIX was resolved via bug ID CSCds23698; for
   LocalDirector, CDCds40921.
