I've ordered a MR3220 on the special which is going to be used for an OpenWRT project for work. I see there is quite a bit of information on the OpenWRT site, but was hoping to get some feedback here on builds, issues and performance from those that have taken the plunge. I seem to getting conflicting reports on webgui for the MR3220, mostly due to memory constraints, yet it looks to have the same as the MR3420, which does support webgui?
