- N800 origin, e.g. Korea, Finland (look at the sticker under the battery), and where it was purchased?
- OS version, if it's upgraded, did you install 56-1 upgrade yourself or did it come with it?
- Brand, model and firmware version of your wireless router/AP, with what security options it is configured (WPA/WPA2, TKIP/AES)?

I even came I even came to extremes of booting to my Windows XP partition today and trying
Nokia upgrade wizard to reflash it again, but that did not help either. I am returning
my N800 on Tuesday. Need to decide however, what's next. I'd love to have
another try, but what are the chances the next one won't fail in the same way?
Since music listening and web browsing is sort of the main intended use for the
box, and I love to do it simultaneously, I'd rather go look elsewhere if N800 is
inherently short in this department...

I will check soon. I am trying to reset this as well. I need to run a few more tests on this.
I purchased this from Nokia and it was already flashed with the recent firmware. I am really annoyed over this, and will call Nokia to see what can be done. Hopfully I can resolve this, as i have installed mplayer and a theme from the previous model. I installed the aim chat package as well as listed from the ok to install - on the 800 series. More later.

Re: N800 reboots when browsing while playing radio

If reflashing the OS doesnot help, then return/exchange the N800.

Re: N800 reboots when browsing while playing radio

Yes, I am planning on calling Nokia Tues. and letting them walk me through the 'procedure' they are required to do. I have flashed the machine and right away tried to browse the web while listening to the streaming media... 10 min. and restarts. I thought it might have been something I installed.

I have read a few threads about these products being made in Korea, is this in any way something to avoid if possible or does this even matter? I love the gadget other than this problem. The browser has crashed a few times with only it running. Maybe I just got a bad one.

Would any settings with the wireless router be responsible? I don't see how this would matter, I am just trying to think of other reasons here.

Re: N800 reboots when browsing while playing radio

Well, my initial thought was also that it might be some of the additional software I had installed, but as I wrote I did reflash it several times and it changed nothing. My next suspect was my Netgear RangeMax 240 router. I've read complaints on Netgear support forum about Intel Centrino wireless chipsets causing laptops to crash with this model. It is mentioned as a fixed bug in the changelog file for the latest firmware I have installed, but you never know what 'fixed' exactly means and what other chipsets may be affected. I also happen to change router's security configuration to WPA2-PSK with AES just before my N800 got delivered. RangeMax has hardware support for AES encryption and I don't know if N800 does, otherwise decrypting in software may put CPU under very heavy load. But I since than tried reverting to WPA-PSK (TKIP), which worked perfectly well with my Nokia 770, and also tried WEP but to no avail. It still locks up and reboots. I wish it's not a common flaw since I love N800 and would like mine exchanged or repaired. So far, looks like only two units affected, it would be interesting to compare serial numbers...

Re: N800 reboots when browsing while playing radio

UPDATE: I am using another wireless connection (D-Link 525) WPA security, open SSID. - All works so far...

Spoke to soon. 25minutes and 2 tries later, same shutdown occurs. I am going to send this back and get a replacement.

Re: N800 reboots when browsing while playing radio

It is somehow related to the connection speed. Reboots only happen when connection is really fast, e.g. full 54Mbit mode 800.11g. You'd probably never get anything even close to that with your cellphone unless you are on some 3G network, even then I doubt. I've tested with WPA already and it still blows up but takes more time to occur, like 30 min initially. After that it however goes on rebooting every 5 min. Looks like a trivial CPU overheating problem to me. Thermal grease not properly applied? I of course have no idea how this OMAP chip is supposed to be cooled...

Re: N800 reboots when browsing while playing radio

Just noticed your latest update AFTER submitting mine. So it's the same - 25/30 min of work initially, then kaboom...

Still wondering how many units may have this fault? You did not check where yours was manufactured?

Re: N800 reboots when browsing while playing radio

Tried WEP (40-bit), it only took N800 10 minutes to blow. Back to WPA2 (AES) and it has already rebooted after 15 seconds of AccuRadio playback. I think I'm done with testing, sending it back.

Made in Korea.

I ordered it the day it was out on the Nokia website. I will call ASAP.
I have also noticed that the internet radio (streaming media) will disconnect and can't find the stream again. Also will not browse a website even though it says it is connected to the wireless router.

This is absolutely frustrating, as I wanted the functionality as advertised. I guess there is a lemon in everything (Rev. A) devices, but I somehow keep thinking positive that it is Ok.

BTW- Do you know how to check the dmesg through using OS X connected to the N800?

Exactly the same behavior here. The symptoms are somewhat connected - sometimes it will just lose connection without any indication (taskbar applet still shows it is connected), the next time it will lock up and shutdown/reboot.

I am still undecided if I should have another try with N800 or wait until I know the issue is resolved. At least next time I will try to get the one assembled in Finland just for a change :)

I guess you have to install xterm on N800 first and become root one way or another (described on maemo.org wiki). You may also install ssh, then you will be able to either open terminal on N800 and run dmesg command from there or login via ssh from your computer (you'll need a client installed on OS X too) and do the same remotely, with the added convenience of being able to use keyboard, cut and paste output to your Mac computer, etc. I am not going to spend my time on this, but will be interested to see the results if you will.
