Héllo All, I made some few tests on EspressoBin-Ultra from GlobalScaleTechnologies, because of problem with the WiFi. I have done some quick tests on all the firmware of PCIEUSB-8997 using the pcieuart8997_combo_v4.bin on OpenWrt 21.02.x Here is a summary of the tests : - W16.68.10.p159 = KO - W16.68.1.p195 = KO - V16.68.1.p145 = OK - 16.68.1.p140 = OK - 16.68.1.p133 = OK - 16.68.1.p97 = OK - 16.68.1.p70 = KO REF (and all details of tests) : https://github.com/NXP/mwifiex-firmware/issues/1 Broken firmware : Version |W16.68.1.p195| of |pcieusb8997_combo_v4.bin| was included into linux-firmware repository by this pull request: https://lore.kernel.org/all/CA+5PVA5yQbjg3vaT7F8120B6ngLn7+sZC0OWt0KoUiQR9hS4FA@xxxxxxxxxxxxxx/ <https://lore.kernel.org/all/CA+5PVA5yQbjg3vaT7F8120B6ngLn7+sZC0OWt0KoUiQR9hS4FA@xxxxxxxxxxxxxx/> And latest version |W16.68.10.p159| of |pcieusb8997_combo_v4.bin| by this pull request: https://lore.kernel.org/linux-firmware/CA+5PVA5on7+CRtEV7tThPxgucwt3W9i-tEXm4cgH-AmMB-Jrtg@xxxxxxxxxxxxxx/ <https://lore.kernel.org/linux-firmware/CA+5PVA5on7+CRtEV7tThPxgucwt3W9i-tEXm4cgH-AmMB-Jrtg@xxxxxxxxxxxxxx/> Olders looks to works better. In quick tests, they allow more than 1 clients at a time ! I am still testing the V16.68.1.p145 and report the results after some longer use... Hopes it will help...
