Why Wifi webgui cannot connect most of the time?

[dony71]

I'm using latest release ESPEasy 20191208
Wifi is connected and I don't see any strange in serial log but why webgui cannot be reached most of the time?
I have erase blank flash memory and reflash, but problem still exist
Router is behind firewall, but is it matters since I just want to connect device locally
Anybody experience the same?

From the router, I notice device connected at TXrate and RXrate 1Mbps all the time
Any hints why?

It is just guessing, but you may want to check the following:
- Orientation of the WiFi module (its antenna) compared to the antenna orientation in the access point
- Metal (or water like a finger) in the neighborhood of the ESP antenna
- Force the ESP module in B/G mode
- send pings from another host to that node (will prevent the ESP going into sleep)
- Check stability of power supply
- Change WiFi channel on access point
- test other node. (there is some serious crap out there, sometimes even between batches from the same seller)
