Mac OS X as the DHCP server seems to be a problem for OS 2007/8 (bug #2478).

Everyone else - do you have QoS enabled in the router/access point? This has caused problems in the past with Belkin wireless routers.

Another thought on this matter, while logging into my Wireless router to check connections I noticed that the N800 connection shows "(null)" as the Client Host Name.

Could this be a reason why some WiFi access points are not letting us connect?

When I did the initial setup on my N800 it asked for a device name, but evidently this device name is not getting sent along to the Access Point as the Client Host Name.

hostname inn xterm reports:

Nokia-N800-50-2

Does this string cause problems on some routers?

This is a theory and you can take it for what its worth

I have two wireless routers - Linksys WRT54G w/hyper wrt and Netgear WGT624v3

Have N810 for a week tomorrow - always connects to linksys but netgear was iffy - got the (unable to retrieve ip) error a lot lately. Just updated firmware on netgear and problem went away - at least for now.

So the question is - Has this occurred on other than netgear? seems like a lot of reports of netgear problems. Just a thought.

This started happening to me last night on my home router, although it had been trouble-free for a week.

After turning the N810 off and on, it connected fine again.

Hi guys! I'm newbie, it's 3rd day as I got my N800(with 2008 OS).
At home I have router Tp-Link and it works good but in the office, where are about 10 networks I get 'Unable to retrieve IP' with each one.
Help, please.

1. Are these "open" (unencrypted) links?
2. If they are, do you have a key (WEP/WPA/WPA2)?
3. Perhaps the networks you see are using MAC-based authentication (i.e., if it doesn't know your MAC address, it won't let you through.)
4. Maybe they aren't really Access Points? (Unlikely that all 10 are ad hoc, but...)

There are definite steps you can take to troubleshoot this problem. It is non-trivial for us to help, since we aren't there to see what is going on. The points above should give you a push in the right direction, though.

sorry im just newbie and got the N800..i flash both OS2008 n ipv6 kernel that i get from Anemone IPv6 Website...when i do cat /proc/net/if_inet6 i can see link local address fe80:XX:XX:XX when i connected to ipv4 only network...which means my N800 already ipv6 enabled..but when i try connect to IPv6 only network, there is Internet Connection Failed. Unable to retrieve IP address. My question is it problem with the software configuration?? because when i attempt to connect to IPv6 network and do cat /proc/net/if_inet6 , i can see 24XX:XX:XX:XX:XX which mean i can get the global IPv6 address..somebody could point me to solution..thanks in advance ya..

Oof. I'm having this problem now, and it's disturbing to see that there doesn't seem to be a general solution.

I upgraded to OS2008. The problem didn't start immediately; wi-fi seemed to work as well as ever for weeks. (I am not connecting to a home router. I'm just connecting to free wi-fi connections.)

A couple weeks ago, though, I began getting the "internet connection failed" message with increasing frequency, using connections that had worked perfectly well before, including connections I could pick up from home. Today it stopped being able to connect to my office wi-fi, which permeates our building, and shows up as a full bar of signal strength on my n800.

These are unencrypted wi-fi connections. They all worked for me before. Now I get a connection very infrequently, if at all. I am at a loss.

Thank you!

I get this issue with the city's public wifi unless I'm close enough to the wireless transmitter.

I got this problem as well, what's the solution?
