[HELP] N900 Not picking up internet connections
 

I've had my N900 for just over 1 year, I've overclocked it to 850mhz for about 1 month so far, and just recently (couple of days ago) I used the NSU to reinstall the operating system, but after a couple of days can't seem to connect to any internet connections. Whenever I scan for access points I always receive this message 'No connections available'. I just tried re-installing the the OS again but unfortunately the same error still remains.

Does anybody have any solutions to fix this issue?
Thanks,
Agilan

open x terminal and type
sudo gainroot
iwconfig wlan0



let me know what you see



edit what MODE is wlan0 at if you see anything

Damn, just realized I don't have rootsh installed anymore because I reinstalled the firmware. However, when I open up terminal I get this

'-sh: /home/user/.bashrc : line 5: cannot create /dev/cgroup/cpu/user/1939/tasks: nonexistent directory'
'-sh: /home/user/.bashrc : line 5: cannot create /dev/cgroup/cpu/user/1939/tasks/notify_on_release: non existent directory'

I just tried connecting the N900 to my computer, it's not showing up :confused:

Re: [HELP] N900 Not picking up internet connections
 

do it without rootsh

the error is connected to speedpatch you have it installed right?



IMPORTANT TRY A DIFFERENT USB PORT

IF YOU DONT HAVE ANY VALUABLE DATA REFLASH THE PHONE

Re: [HELP] N900 Not picking up internet connections
 

those error on x-term is a result when you installed speed patches or battery patches on your device....

Re: [HELP] N900 Not picking up internet connections
 

Yeah guys, that was the other thing I installed speed patch and battery patch before. Could you tell me how to install rootsh without an internet connection on the phone?

I'm thinking of trying

'apt-get purge speedpatch'

Re: [HELP] N900 Not picking up internet connections
 

reflash the phone already!!!!!

Re: [HELP] N900 Not picking up internet connections
 

remove speed/battery patch from your device to solve error on x-term....
as for internet connections why dont you use 3G/2G connection to install rootsh rather than using wifi...

Re: [HELP] N900 Not picking up internet connections
 

I just reflashed the n900 using this image 'flasher-3.5.exe -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f -R'

Problem is still occurring, the speed patch errors in the terminal are still there too.

Re: [HELP] N900 Not picking up internet connections
 

Hey, I'm getting no connections at all, not even from 3G/2G connections :(

Re: [HELP] N900 Not picking up internet connections
 

enable private messages i will help you i promise this evening

Re: [HELP] N900 Not picking up internet connections
 

UPDATE: I have reflashed my phone fully(emmc and combined) , but I am unable to connect to the internet, the speedpatch error is gone, xterminal is normal now.

Re: [HELP] N900 Not picking up internet connections
 

Perhaps you could try with another sim card.

Re: [HELP] N900 Not picking up internet connections
 

Just tried it, same internet connection error still occurring,

Re: [HELP] N900 Not picking up internet connections
 

Get rootsh here http://repository.maemo.org/extras/p..._1.5_armel.deb , transfer it to your N900 via bluetooth or external microSD card and click it in the HildonFileManager. HildonApplicationManager should pop up and install it for you.

Re: [HELP] N900 Not picking up internet connections
 

Could this error have anything to do with speedpatch/batterypatch or overclocking?

Re: [HELP] N900 Not picking up internet connections
 

Could this be a hardware issue? If you can connect to 3G/2G, but not wifi ?
Is the 3G/2G card the same as the wireless one?

Re: [HELP] N900 Not picking up internet connections
 

go to xterminal and without rootsh do a
iwconfig wlan0

Re: [HELP] N900 Not picking up internet connections
 

I would like to test iwconfig on my N900 but when I tried the command I have an error message:
/bin/sh: iwconfig: not found
Do you know which package I need to install to have this command ?
Does-it work with 2G/3G network ?

Thanks

Re: [HELP] N900 Not picking up internet connections
 

its the package wireless tools
root
apt-get install wireless-tools

and i dont think it works with 2/3g

Re: [HELP] N900 Not picking up internet connections
 

Thank you, works great.

Re: [HELP] N900 Not picking up internet connections
 

iwconfig is part of wireless-tools package which is available in the nokia (standard) repository and maemo.org {tools,sdk} repository.

To install this you will need to run (as root):
It does not work with 2G/3G network because it does not comply with 802.11 wireless protocols. You will however see an interface but it will show up without wireless extensions. If you want to see useful information from your 2G/3G network interface you may want to try using ifconfig instead. From memory I believe 2G/3G network interface is known as phonet0.

Back to the main topic, Agilan can you paste your dmesg output?

Re: [HELP] N900 Not picking up internet connections
 

Thanks tuxsavvy, everybody at maemo is being very helpful, really appreciate it :)

I have my n900 in a container of rice at the moment, just a safety measure. What command would I need to use to provide a 'dmeg output'?

Re: [HELP] N900 Not picking up internet connections
 

Agilan, you need to run this in X Terminal:
The file kernel.log should now be in your eMMC which can be accessible via USB Mass Storage Mode and transferred to PC for instance with copying and pasting all the data.

If you're going to paste it here, I suggest you to use pastebin.

Re: [HELP] N900 Not picking up internet connections
 

Tuxsavvy thanks for helping me!
This is the result of the command
Dmesg

Re: [HELP] N900 Not picking up internet connections
 

This is my result for
iwconfig

[ 2.900695] UBI: number of bad PEBs: 1

the only error from dmsg i can spot is a bad block on NAND flash
it is automatically corrected and you will be fine if they stay <20

Re: [HELP] N900 Not picking up internet connections
 

oh spotted something else as well


smc91x: not found (-19)


this is a panic message it means it cant find a device (maybe wlan0)

SOMEONE ELSE WHO KNOWS PLEASE HELP



edit iwconfig wlan0 is just fine thats why I cant tell whats wrong :confused:

Re: [HELP] N900 Not picking up internet connections
 

Apologies, I almost forgot about this thread.

I had a look at your dmesg output, it seems to be incomplete. A more complete looking dmesg output should look something like this.

I'm not saying your dmesg output should be exactly like that but notice how on mine with the ticks (indicated with square brackets followed by numbers) starts with 0.000?

Anyhow, you do have a wireless interface which may mean that there's nothing wrong with the wireless chipset. Have you tried manually scanning? this may not necessarily work in managed mode (note from your pastebin from iwconfig) though you can do something like this:
If you fail to get results when you normally could before, try using something like kismet or aircrack-ng to turn your wireless interface temporarily into monitor interface and see if it picks up APs.

Now before you wonder why I am making you fork out wireless penetration testing tools, these two tools are using other ways to pick up APs from where your device is placed. If either or both of these tools could pick up APs as opposed to using the aforementioned command with iwlist wlan0 scan then retry scanning again with managed mode twice (give a few seconds in between the testing in managed mode). If it fails your chipset may have issue.

Both kismet and aircrack-ng can be obtained from extras-devel repository. kismet can be started via:
The specific tool from aircrack-ng that needs to be started (yes, aircrack-ng is actually a suite) is (as root):
Ctrl+C usually makes these programs exit as it sends an interrupt signal. To get back to managed mode do (as root):
This is not a foolproof method but it might be a way to test and see where the potential culprit maybe.

Do note that overclocking may have damaged internal components of your device. You were forewarned about the risks with overclocking, this could be one of the end result.

Edit: andreas.k: If you want to see a screwed up wireless interface (no wlan0 interface that is) in a log, have a look at this. This came from a person I was helping before that encountered this fault. No idea if the result of this was due to overclocking or what.

Re: [HELP] N900 Not picking up internet connections
 

When I try I get this error

'wlan0 Interface doesn't support scanning : Network is down'

Re: [HELP] N900 Not picking up internet connections
 

i get the same error dont bother.... And i dont have a problem. please try the other steps

Re: [HELP] N900 Not picking up internet connections
 

try (as root):
The interface needs to be up before you can scan, you can't scan because the wireless chip cannot communicate with the rest of the devices due to firmware not being loaded. So you need to have the interface up either way.

Re: [HELP] N900 Not picking up internet connections
 

Thanks, will do. I installed aircrack-ng, how do I install kismet?
this isn't working for me?

Re: [HELP] N900 Not picking up internet connections
 

When I try 'ifconfig wlan0 up'
I get this error 'ifconfig: SIOCSIFFLAGS: No such device'

I'm not sure what this means?
