This is likely to be a basic question for many and so please bear with me.
I understand that 2.4GHz signal has a longer range and better ability to penetrate solid wall, compared with 5GHz signal.
My RT-AC87U sits in room A, sending out both 2,4GHz and 5GHz signals. In room B, I find that the 5GHz signal is stronger than the 2.4GHz one. In a straight line, the router and client is about 10-12 metres apart. And there are 2 concrete walls in between.
This surprises me as I expected the 2.4GHz signal would be stronger in room B. So, what might be the reason(s) for this?
Could it be the 2.4GHz band is having a lot of interference from other 2.4GHz networks of my neighbours? Could this kind of congestion degrade the signal quality?
If this could be, then what router setting(s) can be adjusted to improve?
Currently, the settings are default settings as per Merlin's 378.55.
Ie
Channel bandwidth = 20/40 MHz ;
Control Channel = auto
I imagine 'auto' channel will have the router to choose automatically the best channel to avoid interference and congestion? If this is the case, in what scenario would a manual choice of channel number would bring a benefit?
I am a novice in this and appreciate any help.
Thank you.
