Re: N900 as a Wifi Hotspot, part 2
 

I have been able to get Mobile Hotspot to work with my laptop but there are problems with the connection. Hotspot uses "Celluar data" APN instead of the T-Mobile Internet APN that I normally use. This "Celluar data" APN also does not appear in my Connections in Settings. This causes my laptop to direct me to the T-Mobile website and says my data plan requires an upgrade.

How can I get Hotspot to use my T-Mobile Internet APN instead since that seems to be the problem?

Re: N900 as a Wifi Hotspot, part 2
 

I think I had tried that but it didn't work for some odd reason... but its possible that the drivers did install. ;)

Re: N900 as a Wifi Hotspot, part 2
 

MobileHotspot uses whichever internet connection that has been configured on your device (via the IcD subsystem), you cannot select APN or such values directly via mobilehotspot (only the connection name to use, usually there is only one GPRS type connection...)

Do you use fmms ? It does some twiddling with the data connections' settings, so make sure your device itself is set to use correct APN etc, then re-select the GPRS connection name to use (just to be sure).

If all this is ok and it still doesn't work then your provider is doing some sort of packet inspection to detect connection sharing/tethering; one or both of which might be against the TOS (terms if service).

Re: N900 as a Wifi Hotspot, part 2
 

Rambo, you've really got your **** down. I really appreciate all your support.

How do I uninstall those drivers since i couldn't get fcamera to install to begin with. :( :confused:

Re: N900 as a Wifi Hotspot, part 2
 

Has anyone tried connecting to DS wifi using this, and it worked?

Re: N900 as a Wifi Hotspot, part 2
 

it should be possible to uninstall them via the app manager, if not try (as root) "apt-get remove fcam-drivers"

Re: N900 as a Wifi Hotspot, part 2
 

FYI. Just started MobileHotSpot and was unable to get an IP via DHCP from my son's iPod. I ran up an X Terminal and became root so I could run ifconfig. Wlan0 has an address of 10.212.123.1 with 255.255.255.0. So I manually configured the iPod and bingo! Runs perfectly.

So it seems there may be an issue with serving DHCP on the N900.

Cheers

Re: N900 as a Wifi Hotspot, part 2
 

End user here, so apologies, trying to install mobilehotspot and am told I need application package: wireless tools. is this available via app manager, cant locate it... thanks.

Re: N900 as a Wifi Hotspot, part 2
 

Hey guys, I need some help. I've installed mobile hotspot and iptables by following the directions but yet to be able to get it all to work. How can I troubleshoot to find the problem?

When I try to connect to the wifi signal with my Nokia N82, I get "no gateway reply".

Re: N900 as a Wifi Hotspot, part 2
 

It's not in user/ cateogry so HAM (Hildon Application Manager) does not show it, but will install it as dependency so no problem there (install the powerusers kernel and reboot first to be sure).

The backend does start normally though (via terminal run "sudo mobilehotspot_backend start" to see output) ? Does your N82 get IP address from the DHCP server on N900 (I have no idea how to check on that device so you're on your own with that), what happens if you set the IP manually (see earlier in this thread for details about that) ? Does it work with a laptop ? Does N82 have some sort if ping utility, can you ping the N900 ?

First of all thanks for the reply.

I have started Mobile Hotspot on the backend and it starts up but i have no idea on how to read all the processes going on. I have also tried the connection on my laptop and it does connect but stops at "identifying" and never actually connects.

I would post my xterminal results when I start it from the backend if I knew how...

Re: N900 as a Wifi Hotspot, part 2
 

Hey there rambo,

I'd like to ask a few questions about mobile hotspot :
1. Is it possible to get some logs / counter about actions being performed in the area of "DHCP Requests, Leases, Wireless peers connected, etc"
2. Can this information be viewed in a file?
3. Can it be added to mobile hotspot?

Why?
Lets say I connect some device via wifi, and something goes bad with DHCP, I'd like to be able to check why this is happening.

Cheers mate,
Eitam.

Re: N900 as a Wifi Hotspot, part 2
 

DHCP leases etc I think not, at least without swithing from dnsmasq to full dhcpd.

Wireless peers and (per interface) data counters should be possible as is.

Packet capture (to see DHCP requests [in case dhcpds logging is not enough]) would be possible but is kinda overkill to support in mobilehotspot itself, if you need it you know how to do it from the terminal.

So the information is sort-of available but it's spread around. List of wireless peers is the only thing I'm at the moment planning on adding to the frontend at some point.


Are you using encryption (if so try disabling that first) ? once you post the output I (or someone else) can explain what the lines mean.

What OS and version ? Once you post the hotspot backend output and we know the IP your N900 gets you need to try with manual IP configuration.

There should be a "cursor" icon next to the ctrl, tab etc (if not try swithinc to/from fullscreen), activate it and paint everything, now in the top menu there is option to copy.

Remember to change your encryption password (if you're using encryption) before doing this, otherwise anyone reading this thread can see it.

Re: N900 as a Wifi Hotspot, part 2
 

Hey mate, thanks for the answers.
I do get multiple times where I try to connect my N95 to the N900 via wifi, and there is no internet, most of the time I have to reboot the N900 for it to start working properly, this is the main reason i'd like to see for example a log where it will indicate a DHCP request arrived, and ip x.y.z.c has been given, Now I can open the terminal and try and ping my N95, or oven open a tcp session to it.

Is switching to dhcpd possible? is it installed by default / installable on n900?
Can you give me some directions?
Will mobilehotspot work with dhcpd in the backend?

Cheers!

if you need one with a laptop connected i will post another log but i already spotted an error...

Re: N900 as a Wifi Hotspot, part 2
 

That is not an error that troubles the hotspot (this always heppens the problem is that icd DBUS api lacks introspection support [which sucks in many ways but does not prevent the API from being used]).

This is the important line, here you see the IP N900 uses (10.179.203.1 in your case) and the IPs it should hand out via DHCP 10.179.203.10-10.179.203.100 to setup IP manually set N900 as gateway and DNS server and choose ip with last number between 2-9 or 101-254.

Re: N900 as a Wifi Hotspot, part 2
 

Sorry for asking so many questions, but how do I manually set my N900 gateway and DNS server? I dont know too much about linux or maemo..

thanks for your patience with me so far...

Re: N900 as a Wifi Hotspot, part 2
 

Can't this thing works without Kernel Power?

Re: N900 as a Wifi Hotspot, part 2
 

Short version: no.

Long version: It requires netfilter support from kernel which the stock kernel does not have. If you compile your own kernel then you can use that (see the project homepage for some instructions [they're bit old, I stopped compiling mobilehotspot specific kernels when titan added netfilter to kernel-power]).

This depends on the client device, unfortunately I haven't ever used windows newer than XP (and that I only use very occasionally for gaming or testing with windows only software) so I can't write step-by-step instructions. Basic idea is that somewhere is a place where you configure network connections, there switch from DHCP to "Manual" and as the router/gateway and DNS server address use the N900 IP (as seen in the output of the backend script) then as the client address you any address in the range (except .1 which is the N900).

Re: N900 as a Wifi Hotspot, part 2
 

Does anyone else know how to switch from DHCP to "manual" and how to set the DNS server address? I dont want to start a new thread and clutter the forums. Please feel free to chime in if you have any idea.

Re: N900 as a Wifi Hotspot, part 2
 

In case I was not clear, this is the Vista manual IP configuration, Google is your friend: http://tinyurl.com/275poof

Re: N900 as a Wifi Hotspot, part 2
 

That clear things up a bit for me, rambo. Would I have to do this for every device that connects to my n900? Is there a way to make changes on my n900 so other device can connect to it without having to change any settings?

Re: N900 as a Wifi Hotspot, part 2
 

Well the dnsmasq in DHCP server mode should serve DHCP (automatic IP configuration) just fine and in many cases does, however there are some cases where the client devices don't like the flavor of the dnsmasq DHCP and require manual configuration (or there might be some other issue, I haven't encountered this problem and establishing the root cause with certainty will require fairly extensive knowledge in networking fundamentals).

In some cases manual configuration does not help either (but the "physical" wifi layer claims there's a link), then it get's really hairy to debug.

Re: N900 as a Wifi Hotspot, part 2
 

Installed Titan's kernel yesterday to get Mobile Hotspot working, and after a little playing around I'm extremely impressed. It connected to my brother's N97 Mini, and was giving excellent speeds at a distance of up to 15 metres! I have noticed iPhones and iPods seems a little reluctant to connect to the network, but once they have it works fantastically. I now plan on buying a wifi only iPad to use as a laptop replacement in conjunction with my N900 and Mobile Hotspot for university next year. Nice work Rambo! :)

Re: N900 as a Wifi Hotspot, part 2
 

Hi,
I bought Joikuspot when it was first released but recently got tired of the problems and moved to Mobile Hotspot. I have 2 problems

a) After about 20 to 30 minutes of using mobile hotspot I lose connectivity. When I restart mobilehotspot my phone crashes and reboots. The crash causes the OS to not load Titan when it comes up so I need to then reboot again. What's going on? Joikuspot also died after 20 minutes or so but the phone was super hot and I had to wait until it cooled before I could use it. Is there anything I can do?

b) When I loaded Mobile hotspot I added a shortcut to my desktop. The desktop icon is gone but the Desktop still thinks its there so I can't add it. How do I resolve this? I guess I can remove and reload but was curious if there was a fix. Thanks.

Re: N900 as a Wifi Hotspot, part 2
 

You probably mean the message where it says the saved (overclocking etc) settings were not loaded, no need to reboot you can load the settings from terminal http://wiki.maemo.org/Kernel_Power#C...ltage_settings

Are you running the kernel overclocked and if so how much ?

This crash too sounds like a heating issue, running both radios at full throttle (Ad-Hoc does not support the various WiFi powersaving extensions anyway and cellular will be loaded with traffick) will take plenty of power which equals plenty of waste heat.

There also might be a "crash log" in /dev/mtd2 ("cat /dev/mtd2" in terminal), if the kernel had time to write it before hitting the ground.


I Don't know what's the problem with desktop shortcut, someone else reported that they cannot add one at all, haven't had time to look into it, it's probably something small with the .desktop file.

If someone could try editing the .desktop file on their device and figure out what needs to be changed to get this working I'd be happy.

Re: N900 as a Wifi Hotspot, part 2
 

That's the only problem I have; I can't add a desktop shortcut at all (not an option when selecting Add Shortcut from the edit desktop menu).

Re: N900 as a Wifi Hotspot, part 2
 

Just to 900 MHz. I only over heat using Joikuspot, not with Mobile hotspot. My issue is that Moble Hotspot crashes my phone.

I didn't see anything relevant at the end of my /dev/mtd2

Re: N900 as a Wifi Hotspot, part 2
 

Can i use mobilehotspot with usbnetwork (dummy network) ?

Re: N900 as a Wifi Hotspot, part 2
 

Only bug I've noticed is that Mobile Hotspot will "fail to start" whilst the wall charger is plugged in. Needs to be plugged in once the connection has started. Otherwise, again, worked flawlessly for an hour with an iPad.

Re: N900 as a Wifi Hotspot, part 2
 

You mean having USB network connection via desktop and than sharing that connection over WiFi ?

Not with mobilehotspot per se (you can only select GPRS connections in the frontend) but you can make your own script for sharing the USB connection, it's actually really simple when you don't need to take any general cases into account. Check the thread linked in first post for some examples of early scripts.

Re: N900 as a Wifi Hotspot, part 2
 

I seem to have the exact same problem here. Devices connect fine to the hotspot, and everything just works. However, every time I'm using it, the connection just mysteriously dies at some point. And by 'dies' I mean that nothing goes through, even though devices still claim to be connected and have their IP addresses. The time interval is completely random. Sometimes the connection survives only some minutes, sometimes several hours. Doesn't even seem to depend on the number of clients connected, nor the 3G signal strength. It's not like the device gets hot, either. At this point, stopping the hotspot will reboot the device. Unlike the parent, though, I haven't over clocked even though I have Titan's kernel, so it loads fine after the reboot. Go figure...

Re: N900 as a Wifi Hotspot, part 2
 

Interesting... there was a crash problem related to the IPHB module that some smart guy worked around (need to check the earlier thread) and a bug in the wireless adapter module too (ditto: people smarter [or at least more experienced in kernel debugging] than me worked around those). So it might be that you're somehow unlucky enough to trigger something similar.

In those cases /dev/mtd2 was showing something that helped debugging (AFAIRecall).

Re: N900 as a Wifi Hotspot, part 2
 

I cant get it working, same as joiku, the connection is there, i am able to connect with the ipad, but then im not alloed to surf... Why ?

(i do have the titan Kernel) Thx in Advance

Re: N900 as a Wifi Hotspot, part 2
 

Can you ping the N900 from the iPad (I have no idea if it has or if it's possible to even install the required tools to debug this, much less give step-by-step instructions).

It's also possible that your cellular provider not only forbids "tethering"/"connection sharing" in the contracts but also does packet-inspection on traffic to enforce this (it's possible to detect NAT by examining TCP sequence numbers etc).

Re: N900 as a Wifi Hotspot, part 2
 

Hi, thanks for ur help :), okay i can connect to my n900 from the ipad. But when i want to surf/or use the appstore, the ipad says "no connection" (but i am connected at all). I reflashed my n900 to factory settings and tried Joikuspot, i wondered cause it worked straight away. then i installed MobileHotspot, which worked after all either.After that i started with my own installprocedure...and guess? ^^ nothing of them both worked anymore, so i guess it depends on a/or more certain programm/s which block/s it. One i found out was the Ip-Widget. ah and from the laptop side, i were able to connect too before installing the other apps, even with encryption (only tested WEP)

My Provider didnt locked my connection, i have extra chosen a contract where my ports arent closed, but thanks for the reminder :)

Re: N900 as a Wifi Hotspot, part 2
 

it is a joke? i mean is it for real that in order to have an working application i have to do something with the kernel, and write a script than i have to build up a whole operation system than hack it twice?

i am a regular user. i never even typed in a command or else. i just want my n900 to share the hot spot.

I thought it is enough to buy the phone than follow the installation window. Thats what i did and it does not work.

wonder why should it be so complicated...

Re: N900 as a Wifi Hotspot, part 2
 

Well, then the n900 is the completely wrong phone for you :D

Re: N900 as a Wifi Hotspot, part 2
 

Looks like a troll but I'll bite.

Joiku will be happy to have your business then (not that they have a perfect track-record either but that's never been my problem).

You don't need to write any scripts unless you want to change something the UI does not yet handle or do something the mobilehotspot backend script does not support at all.

Custom kernel is a requirement since the stock one lacks support for something called netfilter (Joiku works around this in "interesting" way).

Frankly the big WARNING about custom kernel is supposed to scare away people who refuse to do a little bit of debugging themselves in the case the things don't go according to the instructions.

Re: N900 as a Wifi Hotspot, part 2
 

was piss easy to install, and works waaaaaaaaay better than joikuspot!

The big start button made me laugh too ;)

If you don't want to risk installing the cutom kernel then do as Rambo says and get joikuspot.
