Slow Net via Ethernet but not through Wifi

[smogsy]

Im confused.

my Internet was slow on all my machines, (macbook MP Vista Ipod) (has been fine for 5 months)

after 5 hours or so they all fixed themselves expect for the MP when im talking slow 0.6kbps download speed

I thought what the hell ill reinstall it should fix it. No luck, i then tried Wifi on the MP & it runs fine 2.3mbps on ubuntu downloads fine.

so any ideas on why MP via Wifi is Fine MP via ethenet is very slow.

i've changed the cables
changed the port on the router.

the only thing i can think of is AppleTalk has died on the router or MP Ethernet ports are dieing?

also
Vista Pc with ethernet - fine
Macbook via wifi - Fine
Macbook via ethernet - slow
MP via wifi - fine
mp via ethernet - slow

I have your ultimate solution: use wifi.

Are you using the same ethernet port on the router? May be a bad port, bad cable...

hows using wifi a solution? its slower even 2 foot away from the router. plus i want to know the reason.

after all my mp is a £3700 machine if its a H/W issue i want it fixed!

ive used 3 cables & 4 ports on the router

Try turning off IPv6 under network preferences (Network-Ethernet-Advanced-TCPIP). If that doesn't solve the problem, you can adjust the Ethernet settings manually (write down existing settings first, so you can revert back).

macbook - fast with IP6 & without
Mac Pro - Slow on both.

So the Macbook doesn't have the problem anymore on Ethernet?

Did you try any manual settings? Or try connecting MP directly to the modem's Ethernet connection?

What are you using to test the speed of these machines?
