I want to setup mesh network in my home on 5 GHz band.I am using ath10k-firmware-qca988x default firmware and driver(no CT) kernel 4.9.129.I am facing issue in 5 GHz where mesh link is creating very easily and fast but i am not getting L3 connectivity(IP,ping and trace route,etc) even RX is nill in both access point.I followed https://wireless.wiki.kernel.org/en/users/drivers/ath10k/mesh with wpa_supplicant and with iw too.The same thing happens quickly in 2.4 GHz band mesh ssid with L3 connectivity. There is not delay or loss in 2.4 GHz band.
Please help me. I have also configured by Luci with 802.11s option.
I've had just the same problem today.
I fixed if by using the ath10k-ct driver and the board.bin and firmware-5.bin_10.2.4-1.0-00025 from https://source.codeaurora.org/quic/qsdk/oss/firmware/ath10k-firmware/plain/ath10k/QCA988X/hw2.0/
Next edit /etc/modules.d/ath10k-ct and change its contents to
ath10k_core rawmode=1 ath10k_pci
After a swift reboot mesh worked just fine.
