~~I'm fairly sure the chipset can do at least 54Mbps.~~ Just checked the local basestation connected clients, my N900 is connected at 54Mbps. In fact I recall that even on N800 the chipset was 54Mbps capable but the CPU could not route network traffic at this speed so in practise speeds were much lower.

154Mbps is not (yet AFAIRecall) real standard even if some manufacturers have similar implementations, ditto for the even higher link-level max-speeds.

Ad-Hoc *might* be limited to 11Mbps in any case.

Any one been able to get this working with Linux? (Arch Linux to be specific, and the wicd network manager).

I've tried now and again over the last few months, with many re-installs and flashes in between, but it never seems to get an IP address, I've tried with encryption disabled and enabled.

If I set a manual IP in my netbooks network settings, it connects for 5 seconds and the disconnects right away.
(IP: 10.39.200.10, netmask: 255.255.255.0, gateway: 10.39.200.1).
All of which seem vaild considering the backend output below:

I have no other machine to test this on, anyone have any ideas?

Don't know if anyone has tested that specific combination, but the issue may be elsewhere.

Can you ping the N900 when you have manual IP set, can you use the arp command to resolve the HW address for the gateway IP. What if you run dhclient manually ?

Mobile Hotspot seems to be a great app for sure but..

...what am I doing wrong when dhcp doesn't work? I tried to connect to network (with/wo WEP) with four devices and none of them are getting IP address. What might cause this?

I had occasion to try Mobile Hotspot for the first time last night. My internet at home died and I tried it. I was unable to get an IP from the N900 on my Linux machine (Gentoo), like others above have mentioned, but on a Windows machine it did work fine and I was able to surf the net.

I'm not at home now so I can't give specific details about it.

I'm also using Windows (XP/Vista) laptops, and S60 phones. Wireless LAN adapter just keeps "acquiring network address"

It seems I need to seriously consider using real dhcpd instead of dnsmasq in dhcp-server mode since many have trouble getting an address from dnsmasq (it might not implement the protocol fully). However those that cannot get address via DHCP, please try manual address (start the backend via terminal to see the IP range it chooses) and report results (and if it doesn't work all the way to internet try pinging at least the N900)

The network manager does show it connected briefly, but I don't believe it actually is: where it shows the connection information, normally looking like so:
Connected to <SSID> <IP ADDRESS> strength: 95%

When I connect to the N900, the strength is reported strange it says:
Connected to <SSID> <IP ADDRESS> strength: ??

I've never seen my network manager do that before.

While it is briefly connected, I am unable to ping the N900, or any other LAN/WAN device.

I'll try the other suggestions you mention shortly and report back shortly.

Thanks.

In Ad-Hoc mode the "signal strength" is not actually meaningful in any way so by convention it's not shown.

Hi, I have the following error:

Code:

DEBUG: executing insmod /lib/modules/2.6.28.10power37/nf_contrack.ko
DEBUG: Command output: insmod: can't read '/lib/modules/2.6.8.10power37/nf_conntrack.ko': No such file or directory

I have the power user kernel (and overclocked to 850), and also I noted that the error reports a file named "nf_conntrack.ko" while the command states it's loading "nf_contrack.ko" so there's a "n" of difference.

What can I do?
