Lenovo X1 Carbon Gen 7: Upgrading WWAN from 4G LTE to 5G
My laptop, a 2019 Lenovo X1 Carbon, was ordered with the optional WWAN interface. At the time, the state-of-the-art was a 4G radio which I added to our Mint Mobile account. I only need to use mobile data occasionally, but it has proven very handy.
Several months ago I noted that it suffered very poor performance at a meeting off-site. This even as my mobile phone was working much better.
Earlier this week, while I was taking Stella to an appointment in another part of the city, the laptop reported being completely offline. It was wholly unable to connect via 4G. I looked at my mobile phone, which reported connected via “5G UC.”
