Note: This was originally written at least a month ago, and somehow, It never got posted. I started up Evolution this morning after not using it for a while, and apparently it had this unsent message in it's queue. I guess my network setup wasn't working very well at all when I wrote this.
I've generally been annoyed that Network Manager in Ubuntu doesn't give you the option to save a dynamic DNS configuration when you save a network configuration that uses DHCP. Also, I'm unhappy that Network Manager doesn't save the Gnome proxy configuration as part of the configuration. But these are minor gripes. I have recently found out that while Network Manager will let me configure my wireless for a static IP, the resulting configuration will not actually work. At all. I can get associated with the access point, and the routes and other network configuration looks fine to me, but I simply cannot send or receive anything. (And in troubleshooting this, I found that Network Manager doesn't save your WPA password between invocations (when you have a static setup), so if you do something like change the configured IP address, you need to remember to also re-enter the WPA password, otherwise, it will happily forget it.)Anyways, I ended up having to figure out wpa_supplicant (which is surprisingly straightforward), and reconnect to the access point manually. Now things work, but with the general amount of polish Ubuntu has been showing lately, I really didn't expect to find something this integral to the system as this unfinished. It just makes me sad. I've seen some reports that Network Manager 0.7 fixes the static IP issues, and that's coming in Intrepid Ibex. Anyways, that's enough pointless complaining. I'm going to do something productive. And perhaps after I move, I'll find enough free time to see if I can help fix some of these problems with Network Manager, because it really is my biggest pain point in Ubuntu these days.
