Cannot connect the default OpenWrt 5g network after connecting OpenWrt router to my ISP router

Installing and Using OpenWrt
4

Another test (on the 2g radio, this time)

  1. Resetting the firmware to its initial state
  2. Defining a specific lan IPv4 address (192.168.20.1), Save, Save & Apply, Apply
  3. Scanning for a 2g wireless network, joining (default options), Save & Apply, I can see the Associated Station (ISP router)
  4. Testing IPv4 Ping from the OpenWrt router : working
  5. Enabling the default OpenWrt Access Point (iface) on that same radio

Then, unlike my 5g first attempt, I am here able to :

  • See that OpenWrt Access Point
  • Join that access point from my computer
  • And browse the web from my computer !

How could that be so different using 5g instead of 2g ? This is what I really don't get for a couple of days now :laughing:
