I have this same issue in my Ram. I ordered the same AR7552 4G card from the link that
@Tallus shared. The card that was sent to me was definitely used and did not work. I confirmed this by removing the card from my 2023 Jeep Wrangler JLUR and placing it in my Ram. The card from the Jeep worked perfectly in my Ram and I immediately saw full satellite signals. I left the card from the Jeep in my truck for two days and it worked perfectly! I then tried the card I received from eBay in both the Jeep and in the truck again and it did not work. Just to make sure that it was the air card that failed in my truck, I then tried the faulty card (that was originally in my truck) in the Jeep and it did not work, as expected.
The eBay listing states that it is "refurbished". The one I received from the eBay seller did not work. I wonder how the seller is "refurbishing" these cards? To me, that would mean replacing the module (chipset) on the card. The card I received did not appear to have a new chipset as it looked pretty faded. I wonder if the seller is even testing these before he sells them on eBay? I tried contacting the seller twice (May 13th and 18th) with questions about how he is confirming the cards work before he ships them, but he is not responding. I went ahead and initiated a return.
Not taking anything away from
@Tallus as we are very appreciative of him guiding us in the right direction to get this issue resolved
Just wanted to give a heads up that the item in the eBay link is a gamble and may not work when you receive it. The most aggravating part about receiving a faulty card is the time it takes to install and uninstall from the truck
This
eBay Link has new modules, which I assume is the component failing on these cards. Does anyone here know how difficult it is to change one of these modules on the card yourself?
I found another eBay seller who has brand new cards for sale. I guess I'll give that a shot. At least I now know for certain that the only issue with my Ram is that the air-card just stopped working (after 5 years) and thanks to this awesome forum, I have a path to fix it. Thanks everyone!!!
