Hello,
So the problem i have is that when i freshly start up the router, first 30s uptime with wireless node i have a -40dBm signal but after that it drops to -59dBm.
I know that the signal is still good but why does it show different levels at the first 30s? Even my phone from that spot can get to -56dBm so shouldn't it be higher than -59dBm with that antenna anyway?
The problem i encountered might not be a problem but a glitch but either way i want to know what exactly is going on because i couldn't find any similar information or issue on web.
Hopefully someone will know the answer to my weird question.
I also don't know what exactly is going on behind the router operation. I may be wrong but my guess is wifi system is an adaptive system, i.e. it will check the receive signal strength and then adjust the transmit power accordingly. That is why people always said Tx power setting on the router is for maximum Tx power that the router can transmit and not necessary that it will transmit at that power all the time.
