wifi stop woring on my ipad air after IOS 11.4 upgrade
I have an ipad air wifi 2013 which worked fine till last april when was asked to upgrade to IOS 11.3 infact WIFI bottom became grey and stopped connecting internet, I went to Apple genius bar ppl they turned me down saying that my old ipad had hardware problems, my wifi antenna was damaged and nothing could be done. But after few weeks I started it up and it was working fine, must probably as ppl here on the community mentioned IOS 11.3 had a bug which was eventually fixed. Then I forgot about this problem .
Last week was asked to upgrade to IOS 11.4 so I did and suddenly same problem came up wifi button turned grey and no more wifi internet connection. So I went again to Apple genius bar ppl who turned me down again with the same issue, my hardware wifi antenna was broken, again I should throw away my old ipad and buy a new one. I insisted reporting what happened back in april but could not care less. So I start searching how to fix the antenna, found the place where to buy a new one, opened my ipad, i replaced the antenna, put back everything in good order but again my ipad wifi bottom remained grey failing to connect internet.
So today i fixed an appointment and met Apple genius bar again to whom I show the new antenna fixing, so they started saying that now is a motherboard problem. I told them that my ipad worked find till IOS 11.4 upgrding, that it mut be a software bug which should be fixed by them and/or they should downgrade such bad IOS to an earlier version, they reply is that APPLE is not capable to return back with downgrade, that I should change my old ipad and left me without any solution.
Pity to see that such an important company like APPLE has so cheap people who could not care less about problems created by APPLE software, they are only interested to SELL new products disregarding my reason that I do not want to change a fine working machine like my old ipad air wifi 2013 ....
I wonder if at all the so much acclaimed IOS 12 will fix the issue, but in any case I would like to know to whom I should write my solid claim as above ??? thank you for any help you can offer. Best regars, Paolo fm Italy
