I have a Marvell Yukon 88E8052 ethernet card which they support with an official driver called sk98lin.

On both Ubuntu 10.10 and 11.10 I get the following results on http://speedtest.net when using sk98lin:

120 Mbps down, 100 Mbps up

On 10.10 without sk98lin (just using the Ubuntu defaults) I get better results:

150 Mpbs down, 120 Mbps up

However, on 11.10 with the defaults I can't even load the speedtest.net website. Everything is incredibly slow. The best results I get when using apt-get (for example) are in the 50 kbps range, and that's after I've tweaked my MTU and messed around with a bunch of settings like disabling IPv6 and setting up DNS manually (without the tweaks it's more like 20 kbps). There are no dropped packets, it's just super slow. This leads me to believe it's a problem with the driver, though of course it might be something else.

How can I fix this? sk98lin is fine, but I'd like to figure out what's going on and hopefully be able to use 11.10 with the 10.10 speeds; that 30 Mbps boost over sk98lin is valuable when downloading large files!

@MarkRooney Hardly. I'd still like an answer. –  Matthew Read Apr 8 '12 at 1:09

According to the man page for Oneiric there is an updated driver for your card.

To compile this driver into the kernel, place the following lines in your kernel configuration file:

       device miibus
       device msk

The page doesn't have a date or version that I saw, how can you tell it's a new update? –  Matthew Read Apr 8 '12 at 8:34
    
my mistake i was looking at the different manpage version - did you try and compile the driver into the kernel? –  Mark Rooney Apr 8 '12 at 9:51
    
Not yet, I'll probably get a chance to try it later this week. –  Matthew Read Apr 9 '12 at 3:07
