I checked the router name and it was this:
Asus RT-AC68U Dual-band. ( It says fully compatible with 802.11b/g/n.)
I'm sure it is caused by: ( Not yet checked the old laptop more because working all time and tired 😉 )
1.) Buffalo Wireless Client Manager (Maybe wrong version or such ?) which asks all kinds of settings when logging to home network:
- Like "encryption key method" or was it "network password encryption" or such.... there are like 5-6 of them to select in the drop down menu.
- The software of the old PCMCIA Wifi card is puzzling and not as straight as plug and play USB Wifi adapters.
2.) No antenna.
3.) Windows 98 SE.
[4.) WPA2 see below.]
Also when using the PCMCIA card the Windows 98 SE startup slows down.
I believe in this 1998 laptop the 32mb(16mb x 2pcs EDO So-dimm 5V) memory is a bottle neck to the Wifi card and software.
When I tried to play a racing game= Lotus III(3) 1993-94 it said "not enough memory" and did not start. 😊
This one has the same card but does not show any software:

One commented the youtube video
"Will not work with WPA2 encryption. You'd have to downgrade your router to WEP, which isn't very secure and some routers don't support, or run your WIFI open with no encryption. It's easier and more secure to use a LAN adapter. It's pointless anyway. There isn't a modern web browser that supports Windows 98 and part of the reason is"
Is there any WPA2 PCMCIA 16-bit 5V cards ?
