I don't think it is only router related? I never noticed this problem (or it wasn't severe enough) prior to my purchase of N800. With 770 I *think* I had some mysterious WiFi disconnects or network slowdowns before, but it never got as bad as with the N800. Now it is very consistent that *any* WiFi connection seem to suffer if Bluetooth is turned on. It is just more sensitive with higher channels like 11. However, my desktop or laptop do not seem to be disturbed about the BT at all. (I have external BT dongle on my desktop and I use BT mouse with my laptop when working without docking station.)

Based on my knowledge (which may be wrong...) the N800 as well as 770 use the same antenna for both BT and WiFi. Therefore the "interference" signal for each other will be significantly stronger than if the antennas were separate.

Ah, interesting. I was looking at the active BT dongle on my laptop sitting just inches from my N800, but if the problem is more likely to appear at the wi-fi router end then there's a good reason I don't see any problem -- I'm located fairly far away from the router, the BT signal wouldn't be at all detectable there. If so, the problem could possibly be reduced by moving away from the router.. I seem to recall several postings pointing out that they had a problem with wi-fi even though the wi-fi router was up close. Obviously the simplest thing to test first is to just switch off BT..

They use the same antenna, but the signal is multiplexed -- that is, it doesn't transmit both at the same time. wi-fi/BT/wi-fi/BT.. (this is from what I could gather from those FCC papers that made us aware of the upcoming new N800).

I'm not saying it's ALL router-- but we're troubleshooting so every factor needs to be examined. I'm just tossing out my own experiences in case it triggers an idea in someone. In my case, if I have trouble with one wifi device in my house I have trouble with them all (1 laptop, 1 770 and 3 N800s). I realize my situation doesn't necessarily translate to everyone, but IMO every angle needs to be examined. tA-t3's point about the possibility of being too close is worthy of exploration I think.

I played with this thing little bit more tonight at hotel. What I can say that with my N800 the WiFi and Bluetooth are absolutely NO-NO to use at the same time.

I'm starting to wonder if my N800 is somehow defective? Anyone has similar symptoms that with Bluetooth on (such as MaemoMapper running and searching GPS receiver, actual GPS receiver was not powered on) your WiFi connection gets very erratic?

The hotel AP seem to be on channel 6... so this does not seem to be related to channel 11 as I previously though.

Maybe it doesn't work with BT enabled... but it doesn't even work with BT disabled.

I love my N800 at home works like a charm... But I have never - ever been able to access the internet through a open wifi on the road. Tried several places, ... even at my parents place (where i know how the wifi router is configured) ... no go.

This bug ,or what should I call it, really makes the N800 worthless out of the house. I'm practically sorry i bought it. Because that was the main reason i got it.

Hope Nokia diggs in to this because it doesn't do the main thing it's build for!!!
What use is a Internet Tablet (for the road) that doesn't connect to the internet. Sorry but this is something that must be fixed asap otherwise I can't see any future in the internet tablet device.

Maybe we should start listing what type access points we're using. I know it's going to be difficult to figure out this for public hotspots, but..
The one I'm currently using is a D-Link Airplus extremeG, works like a charm. Roaming too. (I had local IP problems in the past but it was resolved when we figured out one of them hadn't been updated when we changed essid). I'll be able to test a couple more types at least (later).

I realize I may take heat for doing this again but... I don't know how pervasive your experience is. I *am* able to get on other networks outside my house-- unless I don't have the security key.

It's normal for a person to think their unique experience translates to the general populace, but until I see data supporting such a case, I'm going to keep assuming this is either router issues (including interference) or a hardware problem unique to your N800. In the latter case, I'd return it and try again.

Oh, and to TA-t3's suggestion: I've successfully used Linksys WRT54GC and Netgear WNR854BT. Netgear was more stable. Linksys occasionally needs rebooting.

Hi,

My (linux) experience isn't that great, I myself would say I'm a linux newb. Besides some ubuntu experiments.
But it would be great if you didn't need to be computer expert to use the N800.

Back to the topic:

Is it possible to connect to open non secure WIFI networks?

I was able to connect to multiple WEP secured WIFI networks (that I installed for some friends)

But open non secure networks don't seem to work for me... Am I doing something wrong?

Sure. Public access points are always open, even the ones where you have to pay - that part is taken care of by redirecting you to an https: page the first time you try to set your browser to some web page.

Good, then it works.

Are you sure these are open, public networks? If they are merely without WEP or WPA protection, they could still have MAC filtering on. Try in some airport, hotel or Starbucks - you should at least get a valid IP address.
