MB Pro A1286 early 2011 wi-fi dead - board level problem
First time I see this... wifi won't initialise/work.
Tried 2 known working wifi cards+cables, tried a different chassis completely.
Still, no wifi, no 'no hardware found' message, it's like it's there but not functional as I can see wireless in system report.
Another odd thing - Kingston UV400 SSD would have 400+MB/s write but read speed was lower and on next run, it would halve that under 250MB/s
Goes to say it is inconsistent, not running at same parameters at all times.
If anyone has got any feedback on this - board level issue which may cause this rather strange behaviour, please let me know.
Wifi: A1286, early 2011 and late 2011, also all wi-fi cards from A1286 2010-2012 are compatible. Installed wifi card from another machine then I simply moved the board from its own to another unibody 15'' - and still same symptoms - hence trouble is on the board. no signs of damage to connectors, cables wifi-mobo are fussy but with 3-4 tried, it is obvious.
The 'no hardware installed' message comes up when wifi card fails or ribbon cable goes bad, which indicated trouble on the logic board.
SSD: Kingston UV400 480GB - has just Sierra installed on, just pulled from packaging. Building a couple of A1286 'on steroids'.
Need a 2012 A1286 for Raid 0 ssds...to drag race the retina on speed :)
SSD sits in the hard drive bay as it's SATA III / optical bay sata II in 2011...
Is this a good question?
