connection ok, but no working internet (possible 5GHz mode problem) #136

Open ghost opened 8 years ago

ghost commented 8 years ago

Hi! I have been using your script for a long time, worked flawlessly, but now, I am staying at a hostel, where I study for faculty, and I encounter a problem: the connection works fine after sharing the eth0 internet through WiFi, but after I connect my phone, for example, there is no working internet at all. I discovered a clue: when I use Connectify in Windows, it sends me a warning: "5GHz mode. Some devices might not be able to connect.". Will this be the problem in Linux? It does not support 5GHz mode sharing? What should I do to make it work?

~$ lspci -k | grep -A 3 -i "network"

Give exactly the create_ap command you are running and it's output. Also give me the iw list, iw dev (after you run create_ap). What phone do you have?

The command I use for creating the AP and its output:

My phone is a Samsung Galaxy S2 (GT-I9100). I also tried with my roommate's Iphone 5, and it also doesn't work.

UPDATE: I have no idea what I have done. It works now! I don't now why! I didn't do a thing... Hmm, that is very weird... Thank you for your reply! I guess we can mark it problem solved? If it happens again, I will notify you :)

oblique commented 8 years ago

Maybe the channel had a lot of noise? If it happens again, try channel 6 and 11.
