Background (not the question)
I'm not a hacker, I'm a terribly lazy guy who prefers to download 10 GB Virtual Machine (1 click) than to install a few packages to get software running (stuff never works for me the first time).
I'm spending Xmas with my family and I wanted to synchronise Monero blockchain. Monero uses anonymous protocol I2P and as it was synchronising my WiFi was dropping, now it cannot connect at all.
I speculate ISP is observing the packets an does not like privacy stuff and has banned my MAC address.
(phone and another laptop connected to the same WiFi are working just fine)
Question: looking for a powerful external WiFi dongle
Additional use case - 1 hour WiFi limits at the aiport - yes please. I'm not a hacker, so https://www.aircrack-ng.org/doku.php?id=cracking_wpa is slightly outside my technical expertise.
Which dongle to buy?
EDIT / UPDATE: Changing MAC address works like a charm. Now I can connect to my home WiFi. I still want to buy an external WiFi adapter, this time around the main criterium is POWER and readily available external antenna. Use case: I sit in a nuclear bunker faraday cage workspace and have 10m USB extension with my WiFi card attached.
