I am definitely having wifi issues that are specific to the N900. But, man, when it works- it works very well!

I also notice that if I leave the option to automatically switch to wifi if available, that cause connection issues too. A lot of times 2G will not even connect to the web- even when wifi is not available.

Since disabling the automatic wifi, the connections seem to be a little better. But nowhere near as good as my G1 or the Droid. Ironic and sad- hope they send an update out
