The equipment used by UA for wifi does not impact the AMEX reimbursement for WiFi fees.
There is a thread in the AMEX forum,
https://www.flyertalk.com/forum/amer...s-ua-only.html that addresses your query directly and the answer is yes.
Will move your post to the AMEX forum where you can join the discussion there.
