Having spend a day or two setting up my Ultra 10 on my wireless broadband
connection I thought I'd post my info here, so the next poor shmuck who
tries it doesn't waste as much time/hair as I have.

Basically everything worked, but with very poor throughput. I have a D-Link
Wireless ADSL Router, model DSL604+, it's an all in one box and includes a
built in ADSL modem.
(80 quid at Expansys.co.uk - your mileage may differ...)

I have a PC running windows and a Suse 9.0 box connecting to 2 of the 4
wired 10BaseT ports. So far so good. My Ultra 10 is in the garage as it's
too noisy, I've a Netgear ME101 wireless bridge plugged into the motherboard
based 10/100 LAN on the Ultra, used to work averagely, I've never been too
happy with that item. Bought a Linksys WET11 wireless bridge, this works
much better on the various devices I've tried it with (Slimp3 player PC
etc.) regularly get 300 - 600 kps FTP throughput.

Both of these performed poorly on the SUN box, ping times of 30ms, 40KB/s
FTP speeds, X runs like a dog. Network card shows it's set to 10MB/s Half
Duplex on Autonegotiate.

I dragged the SUN box into the house and tried it on the router with a
wired connection after a reboot it shows 100 M Full Duplex and is as fast as
a fast thing.

Remembering grief with autonegotiate I've had in the past I tinkered with
forcing the network card to various speeds. The WET11 will only recognise
(and light the LAN LED) at 10 MB/s, it will also let me force Full Duplex
at 10MB and runs great.
Ping times are down to 3ms from 30ms, and FTP throughput is up to 600 KB/s
and that's while I'm downloading the latest patch cluster from Sun.

Used /usr/sbin/ndd to check the LAN settings.

Modified /etc/system to force the card to the optimum setting:

        set hme:hme_adv_100fdx_cap=0
        set hme:hme_adv_100hdx_cap=0
        set hme:hme_adv_10fdx_cap=1
        set hme:hme_adv_10hdx_cap=0
        set hme:hme_adv_autoneg_cap=0
