hello all
i have a flashed ds lite with SC lite micro SD
my router is a proprietary french "freebox"
configured this way
wep on
dhcp active with ip limited from 192.168.0.1 to 192.168.0.5
my DS MAC adress associated to 192.168.0.3
i cannot have access to any router log


if i use regular game (like mario kart) no problem to connect
if i use dsftp 2.3 it stop with error connecting
cannot have a regular ip from my router (dhcp request seems to fail)

if i use the wifi_lib_test,
using WFC config cannot connect
on upper screen i can see:
sgip_dhcp_start()
arp: request ip from 0200A8C0 to 0500A8C0 but not 0300A8C0 (hex of 192.168.0.3)
lower screen ASSOCSTATUS_ACQUIRINGDHCP

using manual config with wep on and correctly filled
dhcp and dns auto
no connection with ASSOCSTATUS_ACQUIRINGDHCP
and no arp request on upper screen

using manual config with wep on and correctly filled
dhcp auto and dns correctly filled
same as previous

using manual config with wep on and correctly filled
dhcp and dns filled by default:
192.168.1.139 / 192.168.1.1
Connected!

using manual config with wep on and correctly filled
dhcp and dns correctly filled
192.168.0.3 etc...
Connected!

if it can help for correcting bug and adaptation to various router
dswifi lib is great anyway

anyway if someone can help me to use dsftp which is unable to pick an IP through DHCP request, you're welcome

If you still can't connect because it can't acquire youre dhcp do the following.

Found the solution

In a wifi game you need to go to the settings and enter the settings manually for your connection.

so you need to enter the wifi settings for your connection and select no for auto-obtain ip address.

Now to find this info if using XP

click start > run and type in

cmd /k ipconfig /all

and press enter.

You will need to enter the IP Address of the DS - this will be the same as the IP address shown by doing the above but change the last number to anything between 0 and 99, i used 5 so my ip entered is - xxx.xxx.x.5

the subnet mask is under the ip address in the command window

Gateway is under the subnet mask

Then the Primary and Secondary DNS should be just below.

Now to run Beup or any other wifi app you need to start a wifi game.

For example mario kart, connect to the ds wifi and then reset your DS. RESET, do not turn it of or it wil not work.

I have a supercard so i press the button combination.

Now run BEUP or any other wifi program.

It should connect.

I only have one so I entered the same for both and it worked fine.

I've noticed that resetting Mario Kart DS with the supercard software can corrupt the upper screen. (No it's not broken.) I mean that it could not show the upper screen correctly with beup or win2ds or some apps.

You need to connect with tetris ds and then softreset, then the screen would stay normal.

Try this!! It works for me.

Thanx Hansie
in fact, in the meantime i found the same solution as yours
