I have two laptops (both wifi enabled) and a wireless router. I want to use one of the laptop on a robot and other laptop to SSH into the first one. My question is that is it possible to connect the two pcs even if I dont have a modem or internet and just use the wifi router? If so how to do that?
There is a main WLAN-router/modem which is connected to the internet and serves the lower floor with WLAN. Now upstairs I have a second WLAN-router/modem (I will call it router two from now on). A normal ethernet cable is plugged in in router two in one of the four ethernet ports and also in one of the four ethernet ports in router one.
I have a number of mobile devices including iPhones, an iPad, and Kindle Fires. All of them can connect to my wifi network fine, and get Internet connectivity. After being idle for a variable amount of time (sometimes very short e.g. less than a minute) they lose Internet connectivity. When this happens, they maintain the wifi connection itself.
This is a long ongoing problem. Maybe someone has an idea. I have an ordinary dsl router with wlan at home. I cannot use the wlan under Linux. nm says I am connected (see screenshot), but there is no internet access. I have never been able to connect to the internet using the wifi at home under Linux. Works fine under Windows, but I hardly ever use Win. Recently I got an Android phone.

Yesterday before I went to sleep, I still connect to my wireless access point, this morning when I start my laptop I don't see it in the list - there are some neighbors listed but not mine.
The WLAN is green, with my old N
