The new build is from CyanogenMod, back in the old days (before last November) they used to do an automatic build nearly every night for download & call it a nightly build. Then they had server issues. Now they've collected donations & got a new server. That is the first Blade CM7 nightly build since.
No idea about your wifi. Logs might help. Have you tried GSF? Does your wifi work on that? Does my 22nd of Feb CM7 kernel work after full wipe & reinstall of rom? http://forum.xda-developers.com/show...2&postcount=61
I don't know about GSF...no clue what it is.
But wifi is fine on burstlam and targetbsp.
Btw, I've disabled all screen animations and dithering in performance menu and I'm using on-demand cpu scaling.
I admit that only wiped cache and dalvik cache between builds/kernel changes (which kept wifi going fine with burstlam's build + your Feb 22 kernel; but not with your last build or other kernel from 3-4 days ago). I will try a new clean install eventually...
--> So if I got that right, there are no stock sbfs available for the Blade? I couldn't do a real clean install starting with full sbf flashing? Although, i do reallize that there is no real advantage in doing so with an unlocked bootloader...just an old habbit...
