Why can wifi conflict between android and ubuntu?

Question

Android

facts:
There is a tablet LG G Pad 8.3 on android.
The whole family also has a bunch of phones on the same android in the house.
I work as a proger, so I often sit under ubuntu on a laptop.
At home, wifi is distributed through the zyxel router
Problem:
When ubuntu is turned on on the laptop (Windows is in parallel and everything is fine with it), wifi does not work on the tablet. IP receives, connects successfully. It just doesn't get a response. All other devices are functioning normally. In any other places / networks, the tablet works fine. Only at my house, and just when the know under ubuntu is connected to the network.

Answer 1

Solved the problem myself. There, in general, there was some kind of problem with 802.11 b / g / n, I changed it to b / g and it worked. Ridiculous, but I did not find another solution

Answer 2

Looks like an IP address conflict. Do you happen to have static registered in Ubuntu?

Answer 3

try to configure statics for these two devices in dhcp of the router, and see what happens

Answer 4

Show ifconfig output in full (of all interfaces) with ubuntu.

Answer 5

Damn, but the task was interesting, the guys attacked, and he stupidly decided. No, let's return it as it was and we'll fix it.
To begin with, I would not including ubuntu look at which ip the tablet is working on, then in ubuntu, it is very likely that this is the case.
