Comment (by anonymous):
I found something good on this website. I follow the trick to reboot my
router. On the second rebooted the 5G shows up, it works.

5G radio
Wait the 5G radio not working?
Here is the solution.
Sometimes the 5G wifi interface (a separate AR9580 chip attached on PCIe)
will completely disappear, because the PCIE_RC strap bit gets stuck at
‘0’. This can be checked by running “devmem 0x180600b0” and looking at bit
6:
- GOOD: 0x002F055A
- BAD: 0x002F051A
On OpenWRT this causes the kernel to completely ignore the PCIe interface
and everything attached to it, so only the onchip 2.4GHz radio will work.
On the original firmware it may cause the unit to get stuck in a reboot
loop.
If this happens, just power the unit off for about 30 seconds. In fact it
might be a good idea to power cycle the unit before OpenWRT’s initial
boot. See this thread for more information.
