Report on Wireless status on Ubuntu 8.10 beta

Not much sense to read the rest as I could solve the problem by adding my internal card to the wireless MAC filter of my router. stupid me!


Ubuntu Wireless Problem solved. Brain refreshed

This is what bothers me on the new Ubuntu 8.10 beta on my Thinkpad R52:

  1. Now with a Ralink card (RT61) also this connection is resetted all the time. On reconnection every time the card that never worked with WPA (Intel 2200 BG) is used. The bug has expired (I set it to ‘new’ again) and it was always just commented to update the driver. So nobody at Canonical seems to care if Intel 2200 BG works or not?
  2. Related is the fact that I mentioned above that Network Manager never remebers which card and connection works. So if there is a internal card which cant connect he will ALWAYS use this, even if that has never worked. I reported this months ago and nobody cared., too. What the people working on wireless network do not seem to realize is that not every hardware works with every access point. So remembering what works and what not is so essential! Actually I alwys thoght that was what NM was all about. But it seems they only remember the password/key which has worked  and not how it worked. I guess this is trivial feature to add so again I dont understand why this has not been changed. Or why a card that never worked is even displayed and takes 80% of all entries, while the working card always switches its position (upper or lower end of the other card) – I would guess it would be important to display the most used and working connections at the top – also depending on the location. Come on guys, NM is not that new any more. So please fix those minor issues – I dont see any sense in listing 30 wireless networks in my range that I never use and will never use. What exactly am i supposed to do with them? This is only a distraction.

So my situation now is that not only the internal card is still not working but now the external PCMCIA card is resetted every five minutes or so. Which makes Ubuntu quite unusable for me – and its already Beta time. I had thought ipw2200 drivers would become really much better with newer kernel > 2.6.26, but 2.6.27 I still have the same bugs. So everybody having same type of hardware should stay back from Ubuntu till I can report that things are working.

Here is an example log. As you see wlan0 (rt61) comes up and then eth2 (ipw2200) interferes:

Oct 7 14:44:02 cine avahi-daemon[4897]: Registering new address record for on wlan0.IPv4.

Ubuntu vs. Community?

On Gregs remarks about Ubuntu not giving back to the community and the reactions to it: Funnily I just did organize this SFD and just wrote that Ubuntu/Canonical is the ony distribution which gives out free CDs, although its the smallest distribution. Maybe Ubuntu should hire one or two high profile full time kernel developers – but if I look at what Gregs says in some Google tech talk , I wonder why doesnt he bully Google for not being number one on the list? Google is making the most money out of Linux today and it chose Linux as the basis of its Android platform. Or what about Amazon, Ebay etc.? Does Greg really think Kernel development is only the business for classical distributions?

I think kernel development is a whole different business today. Development is happening at a very fast pace – so you cant say that nothing is happening here and that we desperately need more input. On the other hand many other parts of Linux are in a bad shape.

The number one issue for desktop users as I see it is that you still do not get viable status information for printers. This in fact means that you never quite know whats wrong with your printer when you use Linux. There is no real progress in this area – at least nothing I have seen despite some industry people saying they want better drivers etc. – if one takes this more heartly one could say that this means you can not use printers on Linux. Thats not quite right – you can – but you may need to throw away full ink cartridges of one color because you can not test if its full or not. Nobody really sees that as a big problem. Its not a big thing but I could understand if somebody would dismiss Linux for this reason only. The only good solution would be printers with web interfaces or similar. I guess those are still more expensive.

Other issues on Linux still are power saving modes, Xorg, GNOME, KDE, OpenOffice.org. On GNOME I think Canonical has hired a lot of GNOME people and also a lot of GNOMERs work on Ubuntu for free. Undoubtedly Ubuntu was a breeze of fresh air when it came to the market. It still has its problems – like there is no graphical setting of the screen. There is a program called ‘displayconfig-gtk’ – but thats not part of any System menu – so its hidden – and its usability is awful – and it does not work most of the time. OTOH Ubuntu was the distro who contributed this application to the general public as something like this is not yet part of the GST (GNOME system tools). Other thing is missing is a DSL configuration interface as part of the network configuration. This of today only supports modems, ISDN and ethernet cards (more or less). But DSL or cable is a quite frequent setup.
