Title:
Intel Wireless AC 7260 WiFi: no data transfer on Linux with Dlink AP
(iwlwifi, iwlmvm)
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have a problem with a Wireless connection over a Dlink router using an Intel 7260 rev bb chip (802.11ac speed), or rev 0x144 according to iwlwifi. Another access point has worked well, but this one is not working. If I enable an access point on my Android 4.4.2 device Motorola Moto E (Qualcomm Snapdragon 200), it is working, but it is a mobile connection with limited volume.
On the same PC I have a Windows 7 SP1 64 Bit installation, and am using the full featured Intel driver Wireless_18.11.0_s64.exe. On Windows, I have absolutely no problem with the WiFi connection over Dlink router. Excellent signal strength, and 72 MBit/s speed (WPA2-PSK, AES, 802.11n).
I am using Linux Mint 17.2 which is based on Ubuntu 14.04.2 LTS and uses a 3.16 kernel. I have installed the Linux firmware update and iwlwifi 7260 firmware 14 additionally to test out some newer kernels from ppa. No kernel works, but here is the table of my experiments, referring to https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi and 'modinfo iwlwifi':
Kernel Documented FW FW used (modinfo) FW used (iwlwifi)
3.16 9 9
4.0.9 12 10
4.1.7 13 12
4.2.0 14 12 25.30.14.0 op_mode iwlmvm
4.3.0rc1 14 12
On Linux, the signal strength is much lower than on Windows, about 50%. And I get no data transfer, DNS resolution already fails. The connection seems to be established.
I hope that the functionality of the Windows driver can be transferred to Linux, because it works so well. But it is quite new, from August 2015.
I have seen new uploads for linux-firmware, until firmware 16. Is there a kernel or driver to test it? I could compile it and give a feedback.
I have used the WiFi connection in Germany with an AVM 7490 router
successfully, and am now in Ecuador. All tests have been done in
Ecuador. Setting the regulatory domain to the correct value with "sudo
iw reg set EC" leads to repeated disconnects, so I assume "US" is
working better, it is automatically set according to dmesg dump.
Here is a filtered dmesg dump of the 4.2.0 kernel test:
