I have been trying to get switch config'ed for my net
first thing it caused was my isp gave me a new ip address
got that fixed ,next thing I could not ping IP from outside of net
got the latest firmware upgrade for router first flash failed
cross fingers reset router to default 2nd attempt worked
now I can ping from outside ,but the router and switch both show blinking lights when the modem shows no activity
I have looked into all the log files looked at services and firewall info
going crazy this thing is using 10 to 15 % cpu time before when idle only 0-2%
and connection is slower now
 
I have a adsl modem going to a linksys router going to a intel 8 port switch 550t
when I first set it up lights only blinked when there was communication
the intel manual says green: off 10mps solid 100mps ?
after config of the ports to full duplex and fixing the router
this is what started to happen
I added tcpview software and cannot see why this is going on
my firewall software only shows outside normal activity when I go to a web address
the blinking starts from right to left with the router port connection goes to last port and cycles over again
 
Try it without that Intel switch, i.e. PC --> Linksys router --> ADSL --> Internet
The switch might be fux0red.
Or try straight PC --> ADSL --> Internet
 
just the thought of that scares me silly
open up my pc to the web, the router has builtin firewall
my mcaffe is't the greatest for stopping stuff
I may try to open the port 80 for a time
the switch is brand new ,put old d-link back on and it also does the same thing
