My GL-MT300A 256MB does not give me the wireless network at one specific geo location!
Usually when I power on the device the red/orage led turns on after a while. At that one specific location the red/orange led never lights up and the wifi network never becomes available.
I have been using this device many times over the last years without problems but now I have a strange problem. At one particular location the device does not boot to the point where it exposes the wireless network. If I walk away 100m from that location and try again the device boots correctly and I see my network.
The location is a large building with many floors and 50+ wifi networks visible, so that could be a cause for the issue. When I test the device is right next to me (not on another floor or in another room) and still I do not see any network.
Question: What can I do to troubleshoot and solve this issue?
I am at this location only once every few weeks, so any tests you suggest might take a while to complete…
