I don't see any gprs connection there. How does your N900 connect to Internet?

3g with t-mobile

I use it regularly with my laptop using BT DUN. I was hoping it would be just as easy with these honeycomb tablets.

Android is not (yet) comparable to PC in terms of connectivity. People has to wait til Android 3.x (Honeycomb) to have Bluetooth PAN profile included in the connection settings. (and good luck with DUN) Before that, people used to root and tinker to get Bluetooth PAN/DUN work. So, consider yourself lucky to have gotten a honeycomb, otherwise you might have to root yours like others. ;)

Back to your issue, the script is enabling your N900 to supply Internet to PAN peers. So at least you must have an Internet connection on N900 before your peers could make use of it.

I just re-check the script and it should prompt you for Internet connection first. Was it failed to connect to Internet on N900? Please check by browsing with your N900.

I tried it again enabling the connection first & this is what I get & it never prompts me for a connection to choose. Internet browsing within the phone works.

I spot errors in creating the device bnep0 which did not happen in your previous output you posted at #149: http://talk.maemo.org/showpost.php?p...&postcount=149

In #149:
Code:
+ ifconfig bnep0 down
+ ifconfig bnep0 up
+ ifconfig bnep0 192.168.3.1 netmask 255.255.255.0 up
In your last post:
Code:
+ ifconfig bnep0 down
ifconfig: SIOCGIFFLAGS: No such device
+ ifconfig bnep0 up
ifconfig: SIOCGIFFLAGS: No such device
+ ifconfig bnep0 192.168.3.1 netmask 255.255.255.0 up
ifconfig: SIOCSIFADDR: No such device
Now the gprs0 appreas in the routing table while bnep0 is missing.

What have you changed since #149? Say, have you paired up the devices first?

Restarted the n900 & started the 3g connection before connecting the tablet.

Trying pair again before connecting.

What were the problems you got in #151 and #155?

Not sure. Most of this linux stuff is above my head so I'm just trying different things following the steps best I can. The tablet is connected but isn't getting an internet connection & has no IP. One of the posters here somehow got it to work with his xoom but it's confusing to follow.

I considered wifi tethering, but n900 only does adhoc & Honeycomb tablets don't even see those networks w/o some workaround. Why did google have to make this so difficult?

It'd really help if you could feedback the problems you encountered in details. Nevertheless, you've done correctly on N900 in view of the output in #157.

Have you triggered the "Tethering" under "Bluetooth Settings" on honeycomb's side?
