Ubuntu laptop creates ad hoc wifi and Android can't connect

"I think this is more related to your card - this laptop is fairly old from the research I did on it (~2006-2008?) and it probably shipped with a Dell Wireless card, which Dell does a lot of the time on consumer models. I wouldn't be surprised if this is a chipset problem.

My advice would be to replace the factory wireless card and try your luck from there (Intel is recommended). A lot of Dell's first party wireless cards are nothing but trouble outside of Windows, even if a good chipset vendor is used (My DW 1506/AR9485 seems to be the exception to the rule). Your laptop is old enough to be from the time period when Dell used Broadcom, so I would run ""lspci -nn"" and make sure you are right about this being an Atheros/QCA card. Judging from my research on Parts People a lot of the Dell branded cards are Broadcom."

"@pccheese , your first problem is using Ubuntu 17.04 ;-)

That may be way too bleeding edge for what you are trying to do.

16.04 is LTS, meaning mainstream support for the next 3.5 years, where is 17.04 is experimental and abandoned after a year or two.

Anywho, before I hear it from @nick, to each their own is my retort.

Your problem is you need to either use the Gui to create an Internet connection share, or if you really want to do it via Terminal, you need to use IP tables to forward packets from one Interface to another.
