Hi @dylandoesp30722
Best option is to replace the antenna assembly (supplier example only- search for Alienware 17 R4 antenna assembly to find suppliers that suit you best)
Here's the service manual for the laptop. Go to p.78 to view the necessary pre-requisite steps and then the procedure to remove/replace the antenna assembly.
Hi @dylandoesp30722
Not 100% certain but I think that the original WLAN card in the laptop is a mini PCIe card and the newer WLAN cards are all M.2/NGFF type cards so it won't insert.
If there's room available, you could always try using a M.2 to Mini PCIe adapter (explanation link only). Note the difference between the adapter and the M.2 card shown in the link. The "key slots" in the connectors have to be compatible between the card and the laptop's WLAN motherboard connector so that the card will plug in.
