XDA11s WiFi Problem

Hi
I have a WiFi network at home (802.11g), the network does not broadcast a network name and also has 64bit WEP security active.
When I turn on Wirless Lan On I cannot find my network.
When im out and about and turn Wireless Lan On, I can connect to any network thats available.
Has anyone got any ideas how i can setp up my PDA to work with my Wireless Network at home?
Many thanks

internet access through ad hoc wifi connection?

hi, im not able to connect to the net with my wizard.
i dont have a wireless router so am connecting directly to my laptop, the ad hoc connection i have made works fine for file tranfers, but not for activesync or connecting to the web in either PIE or minimo.
i know activesync isnt possible but surely i should be able to use the broaband from my laptop?
any pointers would be greatly appreciated. software? settings?
its a t-mobile uk vario with qtek test rom.
also anyone know of a remote control utility, i use logmein but would like something a little more menu/macro based for control of media.
cheers

Try turning on Internet Connection Sharing (ICS) on your laptop; that'll make your laptop act a bit more like a router, providing NAT services to the Wizard.
yeah i've tried that, and i've just tried bridging connections (dont really know much about that) but that hasnt worked either.

My configuration
Me too, I use ADHOC connection for my WLAN.
PC configuration:
ADSL connection shared
Adress IP:192.168.1.1 Mask:255.255.255.0
PocketPC configuration:
Adress IP:192.168.1.55 Mask:255.255.255.0 Gateway:192.168.1.1
DNS:80.10.246.2 for Wanadoo
Your problem is certainly the DNS.
You can put 192.168.1.1 too.
so it is possible? cool!.......but im still having problems.
i cant figure out how to enter these settings, not to sure where to put them,
iv tried puttin the DNS in the -> connections -> vpn
and -> network cards -> networks adapters -> SDIO WLAN Wireless Adapter
sorry to be a pain, but could you point me to where to get each address and where to put them?
also is there anything particular you did to set up the adhoc network? i just used the Windows XP wizard and then ticket the AdHoc option after.
my laptop is conected to the router and the router is connected to aol adsl.
the ip address of my laptop is showing as a simple 10.0.0. number on the LAN but "Autoconfiguration IP Address. . . : 169.254.235.147" for the WLAN
none of my setup has a static ip address, could this be causing the problems?
thanks

It's more hazardous without static adress but it's can work.
My PC has directly access to the Internet with a ADSL modem.
It's here (network cards -> networks adapters -> SDIO WLAN Wireless Adapter )
Apparently, it's ok for your PC and the Ad-Hoc mode.
Maybe, you should have your adress IP WLAN on the same network adress of your router.
I GOT IT WORKING!!!
I started again from scratch.
set a new WLAN. added new setup to the vario, added the DNS etc to the vario.
the problem i was having was the way i was sharing the internet connection, i was trying to shared the internet from the wireless to the lan rather than the internet from the lan to the wireless (if that makes sense to anyone!!!). i also ticked all the connection sharing services to allow them, just need to go through them and see which i dont need now.
thanks for the help guys

(its showing my transfer rate as 11Mbps, although i think iv done the G tweak and my laptop says its got a G card. what speeds should i be getting?)

Internet access via home WIFI network

I am having a seriously senior moment.....
I have a GPRS connection on my Hermes 300 running WM5 which connects to the internet OK, and I have a WIFI connection on it which connects to my home network OK. My home network also works through an ADSL wireless router / hub to connect to the internet.
How do I arrange my Hermes WIFI connection to access the internet via the ADSL router? my mind is totally blank on this

AT&T 8525 Internet Sharing to Wireless Router?

I am getting ready to head on vacation and I want to use my 8525 as my "Gateway" as there will be 5 of us with laptops and I want to share my 3G connection so here is what I did. I connect my 8525 to my Laptop via usb, I start internet sharing on the 8525 and in my laptop (vista) under network connections I see Local Area Connection 6, remote NDIS based Internet Sharing Device. I right click this connection and select Sharing, and enable internet connection sharing on it. Then what I did was took my router (linksys) and disabled dhcp, but enabled wireless and didnt set any wep or wpa. I connect from my laptop to a port on the router (not the internet port) and then goto another laptop to see if I have internet. I dont, I can see the ssid, I can connect but I do not have internet access. Should I use a crossover cable? What do I have to do so that all of us can have internet thru my phone? Oh, my laptop does have internet (from the usb connection on the phone). I tried to setup the router so that dhcp was enabled, but then I kept getting an ip conflict error, so we cant do that. Also I am not getting an ip on the wireless, it has an ip of like 169.254.177.12.
Any ideas?
Thanks
Jim
There a software which you can install on 8525 and turn it into a wifi internet sharing but I don't know if it capable of handing up to 5 laptops. You might be able to use this software and get a router with some custom firmware which allow bridging then set it up to have router access the internet from 8525 wifi and share it among the 5 laptops but I am not sure if you could bridging and do wifi AP on the same router if not then you'll probably need to have 2 router one to bridge from 8525 wifi and then connect cable to another router that will be an AP for the laptops.
That would be my best guess of doing this unless one of the laptop can do AP via wifi when 8525 is plugged into usb slot.

HD2 as wirelss usb device?

Hi, I got a laptop without a wireless card for internet connection. So I've been using my HD2 as a USB wireless device, which gives me internet everywhere. THat very nice, and it works extremely well, however I got a question. WHen at home and at work I would like to connect to the wireless router, and not to my mobile internet, is that possible?
Because even tho i connect without problem to my own router at home, I cant really make my HD2 use that for my computer. Is it even possible?
nope... and that is the whole purpose of a wireless card, to pick up wifi signals from a router
It is possible.
Use ICS Control:
http://forum.xda-developers.com/showthread.php?t=377047
Setup should be as follows:
public interface: BCMSDDHD1
private interface: RNDISFN1
Connect your HD2 to WiFi network, click "Start ICS" and plug the cable in to your PC. Should work If you have XP, you should kill Active Sync process first.
Thank you, however I'm not sure that I do everything correctly.
There's quite a lot of settings in that pieve of software, is all I have to edit really the public and private interface drop down boxes? Nothing else?
And when connection to wifi, shall i then just minimize ICS controls, go to phone settings and connect to wifi there?
Thank you
What you want is for your phone to connect to the internet through wireless connection, not your phone's data/internet connection?
If so, then it's definitely possible. Not only at home and work, but also at many wifi spots throughout the world. How you go about it depends on some things.
Does your home and/or work wireless router connect straight to the internet (such as a connection from the wireless router to a cable modem, etc.) ? If so, you only need to know how to connect with the wireless router and your phone should default to that connection for internet when your phone's wifi is turned on. You can always turn data connection off when you turn wifi on to make sure it goes through wifi.
If your wireless router does not connect directly to the internet but one of the computers on the router's network does, then you'll have to use Internet Connection Sharing (ICS) on that internet enabled computer as posted about above.
I want my phone connected to the wifi router, simple yes. However, then I want my phone to share the internet from the router, with a computer connected to the phone via usb cable.
So my phone will actually work as a wireless usb device, connecting to a wifi router.
WMWiFi Router provides following options on the phone:
1)3G converting to WiFi
2)3G converting to USB
3)3G converting to BlueTooth
4)WiFi converting to USB
5)USB converting to WiFi
