take a look at http://ubuntuforums.org/showthread.php?t=2283277 so far After spending some time with my problem i can say the following:
On Ubuntu 16.04 x86_64 with kernel 3.16.0-30 - it works both edimax 1.1 (at this time on edimax site ) linux kernel (it seem to be identical with the 2.2. mediatek driver on mediatek site ) and http://hprath.com/2014/06/cisco-link...-driver-patch/ The main diferences are (and apply also to 4.x.xx kernels !) : 1. the edimax driver complain about not finding RT2870.dat file (not 2860.dat file that the driver provide ). Also, after feeding with correct file, it can be used somehow. It require: modprobe mt75xx.ko (load kernel module) at this time if you issue ifconfig ra0 you will see NO HWAddr (mac) on the ra0. next ifconfig ra0 up at this moment, it will complain about RT2870.dat (see dmesg complete path) if you feed with hprath provided RT2870 config file but if succesfull you will see the mac on ifconfig ra0 in order to be able to build the driver without error you have to fix __DATE__ and __TIME__ macros and also a fs security struct which is defined fsuid /fsgid (just search for fsuid in the source tree ) and need be replaced from int to kgid_t (and also kuid_t for fsuid) like this (file include/os/rt_linux.h) typedef struct _OS_FS_INFO_ { kuid_t fsuid; // in original driver file is int kgid_t fsgid; // in in original instead kgid_t mm_segment_t fs; } OS_FS_INFO; 2. with hprath will work from the begining and also 3. Neither will work on vbox guest ubuntu 14.0.3 on windows host - both complain about not being able to load firmware. ERROR!!! NICLoadFirmware failed, Status[=0x00000001] You have to deal with os/linux/config.mk settings in order to find best build options in order the adapter to work with wpa_supplicant and NetworkManager. Do not forget to make clean before make Take a look also bellow (important). On the 4.x.xx kernels (original kernels for 16.04) you can compile the but you have to deal with more problems: like EEPROM 0x02 must be 0x01 also, neither drivers won`t load RT2870 file because of a strange error "no file read method" (https://gist.github.com/moutend/cb35a37297910c99d3e2 can provide more suggestion in order to fix this ) if you issue, after ra0 up, iwpriv command, the adapter will work, but the connection will be very slow iwpriv ra0 set WirelessMode=8 //iwconfig will show 5Ghz after that instead on 2.5Ghz on some more NetworkManager restart may be required. Please note that an ath9k will show IEEE8... on iwconfig - strings that are missing from iwconfig ra0 No need to restart Note: if you feed the driver with wpa_supplicant -ira0 -c/some_wpa_config -Dwext some strange things happens including usb device disconnect... maybe more things to investigate -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1427587 Title: Missing driver for EW-7711ULC USB wifi dongle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1427587/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
