LUA Wi Fi module doesn't survive Wi Fi channel change

I'm using the latest LUA built with the latest SDK. I've noticed that LUA Wi Fi module doesn't survive Wi Fi channel change. Basically it looses network connectivity indefinitely. Is there a way around that?

I've noticed that other devices such as Android tablets or Linux boxes do survive channel change and shortly after re-connect to the network just fine on the new channel.

The LUA Wi Fi module is very good in re-connecting if the Wi Fi disappears for example and it comes back. However this channel change business is where I see a problem which I am hoping to solve -- yes I know this isn't common, who changes channels, etc but let's get beyond that and do embrace the use case at hand and assist me with some good ideas!

Thank you!

If you can confirm this to be a bug then please report it at https://github.com/nodemcu/nodemcu-firmware/issues

It may help improve the distance on some of these devices I also had another wonder if anyone soldered an SMA connector and threw an antenna on their board as well to improve the signal quality as well?
