hi!

just got an iPhone 3 days ago, mistakenly upgraded to 1.1.3, downgraded to 1.1.1 and 4.01.13_G and unlocked with anySIM.
I live in Europe, carrier provides no EDGE and got no WLAN in my village. So had to do that in a town ~20 miles away. I 've got
an XP laptop, with a wireless 802.11g built-in and a cable LAN connection. So I'd like to share my LAN's ADSL connection with
the iPhone using my wireless adaptor as a hotspot. Reading a bit about it convinced me it's possible.

There's two approaches I found. Easier it seems is to set up a DHCP ad-hoc on your wi-fi adaptor and bridge the two connections
on your laptop. Done that, failed miserably. None of the connections work (even after a reboot).

Second is to create an ad-hoc (DHCP or static eg 192.168.0.1) on your wireless adaptor and use Internet Connection Sharing (ICS)
on your LAN adaptor. Using this method I got closer. In the DHCP version I get an IP, Subnet, Router and DNS automatically on my
iPhone, can ping the iPhone from cmd but cannot ping the PC from vt100 and Safari times out - so no Internet although I can see
the ad-hoc and connect to it succesfully. Static version, connects but I'm not sure what to use as router (I guess the DNS servers are
the same as my LAN connection). Anyways, I try both my wi-fi 192.168.0.1 and my LAN IP but none works - same results as above.

I make sure that I have the right settings (ICS, win manage connection, ad-hoc only, pc to pc etc) but nothing seems to work.
Do you guys have any idea how I can get around this? any help much appreciated

try to use OpenDNS on the Iphone

208.67.222.222
208.67.220.220

If that fails

try with MagicDHCP,google for it.

little bit ostic to configure but works!

The second method you are trying is the key.

First setup an ad-hoc connection and then share the lan with the wifi one...

Before I list the steps, make sure your firewall is turned off. That might be causing you not being able to ping your pc from the Term-vt100 on the iPhone.


Let me list the steps which i followed while doing this sometime back...

1. Goto Control Panel -> Network Connections
2. Right Click "Wireless Network Connection" -> Select Properties
3. Select the "Wireless Networks" Tab
4. In the prefered networks, select add
5. Enter a Network Name(SSID) eg adhoc
6. Set the Network Authentication as Open and check the box with "This is a computer-to-computer (ad-hoc);"
7. Click Ok. Go back to the general tab.
8. Select IPv4 and manually set the
IP address: 192.168.1.10
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1

Preferred DNS : 208.67.222.222
Alt DNS: 208.67.220.220

9. Now save the settings and turn on the wifi on both the laptop and the iPhone.
10. Set the IP address settings as static on the iPhone and set it as 192.168.1.11
and rest of the settings as above.

11. Next Turn the firewall down.
12. Select the Internet Sharing wizard then share the connection between the LAN and the wifi.

Hopefully this will work.

Thanks Derter and Razor, it's great to have some backing on this one

I was pretty much trying along those lines with OpenDNS and ICS.

Razor the extra step (12) of running the IC wizard got me a bit closer...
I now get "No route to host - Host is down" when I ping from the
vt100...still no internet though

Derter I tried with MagicDHCP as well...boy this program is complicated!
Anyway, I got it running and got an IP etc on iPhone but still same results
as b4. I guess it's not the iPhone's fault or the wired connection but
rather something related to the wireless adaptor.

Once again many thanks guys...back to the fight now

hmm....seems problem has to do with the router between LAN and Wi-Fi after all...
can ping the iphone even when I'm not connected to the LAN so Wi-Fi and iphone communicate allright. I tried to restore windock in case this was the problem but no luck...I'll let you know if I manage to get it working.

update:

I also managed to connect with Winscp...good connection speeds but after a while I get this:

Host has not answered for more than 15 seconds. Warning: aborting this operation will close connection.

ai, ai, ai ....

fisrt connection with winscp take about 40 second.
if the connection crash you have a firewall running on the router(or xp) that stop connection.
you have to open the port on the router for winscp to work.
I managed internet to work with ics and a bridge + OpenDns.
I also made magicdhcp to work + opendns
try with a static bridge and with a dhcp bridge and always Opendns.
Once you get connection,you can try your default dns.

anyway,if you get it to work the connection result unstable,at least in my case.

I know that you don't wont spend money,but the best solution is to buy an access point,or a dsl wi-fi modem/router.

my bad about the winscp connection...
it turns out it only hangs when I try to copy files from the iphone that it needs for the wi-fi connection. Otherwise I managed to download the whole iphone disk on my PC and upload ~60Mb to the iphone with no problems.

I have no firewall running at all...the problem I thing has to do with the way my wi-fi adaptor communicates with the LAN adaptor. The Wi-Fi to iPhone connection works fine. I also figured that's quite a common problem. I'll give it another shot and try with a wireless router this weekend. If I don't get it to work and I see some light with the router then I'll buy one myself.

For the moment I'll try the bridge solution that you suggested. By the way, on the iPhone do I set the router IP address to the one of my wireless adaptor (192.168.1.10)? Once again grateful 4ur help mate! Cheers

I had the same problem with winscp.

when you open winscp in file protocol select "SCP".

For your internet connection:
Post your lan adapter model.
i'll check if is possible to install a driver with Soft Ap.
So that it will work like an access point.
i did it on Atereos adapter.
