I'd like to add, that I have tried switching between the mac80211 rtl8781 driver to the ieee80211 r8187 driver, and still no luck, it took a little more time to freeze like 5-7 minutes. I even tried to do it at another network and no luck it froze at #Data 8xxx, sth like 2 or 3 minutes.
I own two chipset with injection capabilites, AR9285 - lspci:
And rt2561 - lspci:
03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
I do exactly the same procedure, exact conditions, and I can decrypt my own WEP key with no problems at all.
02:09.0 Network controller: RaLink RT2561/RT61 802.11g PCI
I already talked to a vendor that sells the ALFA AWUS036H, with the same chipset RTL8187L and says that it is full compatible "out of the box" and no issues like this one won't happen. What do you guys think?
