broadcom cards connection problem
My clients (mainly DELL XPS) with Win10 and Broadcom wifi cards (DellWifi 1560, 1820A) reported random 2-3 times a day rejoins to AP. They was connected to R700 AP with ZD1100 22.214.171.124.218 . So we do upgrade to latest ZD1100 126.96.36.199.29 . But now they are completly out - they cant connect to EAP 802.1x AES network anymore. Windows drivers was not changed but they cant connect. changing drivers up/down versions doesnt help too.
Clients with XPS but other vendor cards (intel,killer...) are ok.
On internet there are lot of issues with win10 and broadcom cards, but with previous ZD fw it worked (with disjoins but worked ).
Is there something specific issues/recommendation for Broadcom cards ?
Thank you for any advice for specific broadcom tuning my ZD.
