Then your posting about having wifi down the street wasn’t really relevant, was it?
WEP was broken by design, it was cracked even before it became "standard" and keysize (64bit or 128bit) didn’t really matter. WAP ("WAP1") uses 128bit keys, but new set of keys per package (Temporal Key Integrity Protocol, TKIP) unless you go "enterprise" with 802.1X authentication, which then also gives you AES and CCMP. Anyways, WPA was meant as a stopgap while "proper" WPA, aka WPA2/ieee 802.11i, was being implemented which made AES mandatory. The idea was that any hardware capable of WEP should also be capable of WPA, while WPA2 would most often require new hardware. Regardless of wpa or wpa2, with pre-shared key (PSK) anyone who snaps up that key somehow, can read all traffic on that wlan, as the PSK pretty much is the master key used to generate the other keys used with all attached sessions, while with 802.1X, each device gets its own master key for that session. The problem for Amiga now is that we are entering into WPA2/WPA3-only wifi access points, and 802.11b support also vanish. So the only "legacy safe" way forward is to have a dedicated VLAN with a dedicated legacy access point supporting old wep/wpa and 2.4GHz 802.11b, keep signal strength low, firewall it from the rest of the networls and monitor it closely.
Come again next week for crash course in IPv6, DNs64/NAT64, 464XLAT, DS-Lite (not the Nintendo) and why it all matters.
For the record, you brought up wep. I never use internet on the Amiga, whats the point.
Thanks for the lovely rambling,
