Hi everyone!
I bought this usb wifi adapter, b/c i wanted to make an ad-hoc network with my Ipad, so i can watch Bluray (1080p) w/o a problem.
I've got a pci adapter (bcm4327) and it works, but soometimes the image freeze. It is an abg adapter, so it's not fast enough. The usb one is bgn.
I can set alright the card to ad-hoc:
| Code: |
ifconfig wlan0 down
iwconfig wlan0 mode Ad-Hoc
iwconfig wlan0 essig gentoo channel 11
ifconfig wlan0 10.42.0.1/24 |
the network seems to work
ifconfig wlan0
| Code: | eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

And yes, i tried switching eth0 off and removing the module (or backlisted it) and the same.
No device (ipad, smartphone) can see my network (gentoo).
I searched a lot and i really don't konow what to do.
Am i missing something or the advertised ad-hoc is a big fat lie. |
