MB Pro A1286 early 2011 wi-fi dead - board level problem
Hi,
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.
Thanks!

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?

WiFi: First, are you working with two systems which are part of the same series?
You talk about swapping parts around between the two systems. Do the parts from the questionable system for in the known good system?
Please clarify what you have done and if one or both systems are not working here and are the SAME series.
SSD: Can you explain your drive config, is the SSD sitting in the HD bay or the Optical bay? How much free space do you have and what is your OS version.
