wget bad address when yeeloong install

[Sebul]

I have 8089D http://www.lemote.com/en/products/Notebook/2010/0310/112.html
I tried gentoo install on it.
I referred http://www.gentoo.org/proj/en/base/mips/yeeloong.xml
and I made my desktop an tftp server and put netboot-yeeloong.img on it.

PMON> ifaddr rtl0 192.168.11.5
PMON> load tftp://192.168.11.4/netboot-yeeloong.img
PMON> g
...

mke2fs /dev/sda1
mkswap /dev/sda2
mkfs.ext4 /dev/sda3

Mount it

mkdir -p /mnt/gentoo
mkdir -p /mnt/gentoo/boot
mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
Good. But when
wget http://gentoo.osuosl.org/experimental/mips/desktop-loongson2f/desktop-loongson2f-hardened-20130124.tar.lzma
says
bad address
How can I solve it ?

Check your /etc/resolv.conf. It appears you used an unusual DHCP method, so the resolver was probably not configured.

I wget desktop-loongson2f-hardened-20130124.tar.lzma file to other PC, and save it to USB. and mount USB to my 8089D and copy .lzma file to /mnt/gentoo
and proceed next step.
and before reboot
I copy vmlinuz to / directory.
My gentoo installation success.
