BTW, the IBM connects to both the 5G and 2G networks with either adapter.
I got a used computer (HP) to replace a Thinkcentre (IBM), Win 7. The HP is more robust - more memory, faster processor, Win 10, etc. Each has a usb wireless network adaptor. No matter which adaptor I use on the HP, it won't connect to the 5G network and it only gets 6.xx download speed and 5.5 upload. The IBM gets 49.xx and 7.9 respectively. What can I check/adjust to see where the issue is?
