I get all my internet thru a 4G wifi hotspot with a sim card installed. No cable. No modem. No fiber. No satellite. No router. Just the hotspot.
Laptop wifi stops working when I connect an external USB connected spinning HDD. Started happening about 2 or 3 weeks ago, maybe longer back. Has now gotten much worse. Any ideas about possible causes and solution?
Same issue when I try to connect to the hotspot on my Android phone.
Forum search and google search didn’t reveal anything relevant.
I saw this article (it’s for a guy running Windows 7 but it sounds very similar). The suggestion was that the USB device is causing interference due to improper shielding. Does your laptop have a metal body? Is there a way you could try a different USB cable?
