N900 as a Wifi Hotspot, part 2 - Page 21 - maemo.org

Corso85 | # 201 | 2010-07-05, 12:58 | Report

Hi all

I've done something stupid and updated to 1.2. Now MobileHotspot does not work anymore :-(. The one app that was stopping me from selling the n900.

Anywayz. I tried the following:
1. Installed from extras-testing. rebooted.
2. Followed the instructions on http://mobilehotspot.garage.maemo.org/ and rebooted.

in Both cases it didn't work. What happens is:

It connects to 3g. then after 2 or 3 seconds it says Hotspot failed to start.

Nonetheless, I can see the access point from my iPod and laptop and when I connect to it. I get an IP. but I don't get an internet connection. like nothing opens.

Launching it from terminal gives me this error:

ERROR: dbus.proxies:Introspect error on :1.79:/com/nokia/icd2: dbus.exceptions.dbusexception: org.freedesktop.dbus.error.notsupported: unsupported interface or metho.

HELP. Thanks

This error is irrelevant.

However first install the power kernel and reboot then try again running from terminal and post full ouput (remember to change WEP password first).

The iptables package installation is somehow broken, try (in terminal, as root) "apt-get install --reinstall iptables".

"apt-get install --reinstall iptables" didn't work. It said iptables cannot be downloaded.

So I went with:
dpkg --purge mobilehotspot
dpkg --purge iptables
apt-get install iptables
apt-get install mobilehotspot
reboot

It's working now. yay! Thanks.

It pro'ly isn't configured to scan Ad Hoc connections. Android isn't either.

On Android you can change that if you have root access.

edit /system/etc/wifi/tiwlan.ini to read:

Code:

WiFiAdHoc = 1
dot11DesiredSSID = N900AdHoc (or whatever)
dot11DesiredBSSType = 0

edit /data/misc/wifi/wpa_supplicant.conf to read:

Code:

ctrl_interface=tiwlan0
update_config=1
eapol_version=1
ap_scan=2 (tells wpa_supplicant to scan hidden networks)

You're gonna have to root around in PS3 to find similar files... As you can tell, I don't know a dang thing about PS3.

the new update of mobile hotspot works for me where the previous 1 didnt!! yay
but is it possible for it to act as a gateway for my router
as i have set my router as a repeater meaning it can pick up wifi signal and distribute through the lan and create a new wifi signal to distribute over
