What WIFI chipset for AP+STA combinated ?

Post by ffvc@free.fr » Thu May 07, 2020 5:01 pm

Hi Hardkernel forum team, i have bought some HC1/XU4, very fine boards, thank's, but have a wifi AP+STA pb.

odroidhc1 / kernel: armbian 4.14 / wifi module 3
lsusb -> Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter ).
lsmod -> rtl_usb 20480 1 rtl8192cu

After rebuild hostapd (to suport nl80211)/AP + wpa_supplicant/STA runs fine but not simultaneously (when wpa_supp connects in STA (AP shutdown, etc..)).
In fact that seems normal because in iw combination is not supported.

What 's the best chipset you advise me (rtl8812, rtl8814, rt3572/5572, mt7601, atheros, cypress) which supports AP+STA at SAME TIME.

Thank's for light.
Have a nice day
Frederic

I've just seen WiFi module 3 RTL8188CUS can support the concurrent mode once you build the device driver with a simple configuration change.

Hi, solution provided generates too pbs. Even they are workarounded, at the end solution don't runs oups.

Any suggestions are welcome

I have no idea if you successfully built the customized device driver.
I hope other expert users can help you.

BTW, do you need a 5Ghz+2.4Ghz simultaneous AP+STA transceiver?

Yes I have succesfully build some drivers and hostapd and create 2 virtual interfaces to test.
No problem I go to other solution, too instable solution and ! portable.
Thank's odroid.
