I have a old linksys wired router connected to road runner service. Then I have a brand new Linksys 16 port switch. The pc's in my network are connected to the switch. When connected to the switch the internet is very slow.
I first connected my labtop directly to the cable modem. Ran a test through http://www.speakeasy.net/speedtest
. Test came back fine 6880kbps down and around 500kbps up. So the isp connection is fine. I then connected the modem to the router in the Wan port. then the labtop to a normal port. Again the test runs fine, same results as above.
Then I connect the 16 port switch to the router and the labtop to the switch. I have tried two different ways with same results, first through the uplink port on the router, then second just a normal port to the switch. Both ways results in very slow internet speeds. Test results vary, averaging aroung 3300kbps, the upload is always ok.
My first thought was the cables themselfs. I ever found some info that says the minimum cable length is 2.5m or around 8 ft. So I made new cables and for good measure made them 10ft. This did not help.
I then tried an old 8port 10/100 switch I had that seems to work ok. The test are better, but erratic and still no where near 6880kbps.
Sorry for the long post but I'm stumped. As far as setting the devices to auto or full duplex, I am not fimiliar with how to do this on a router or switch, the labtop is set to auto. My thought we be to replace the old router.......
