Does the QCA SoC comes without heatsink?
If that is true might be an indication of > 1GHZ when OCed?

lspci gives this:
root@OpenWrt:~# lspci -v 01:00.0 Network controller: Atheros Communications Inc. Device 003cYou are correct. I was referring to the revision of the 5GHz PCIe card.
According to your lspci those cards should be supported by ath10k. 003c is found in source code.
#define QCA988X_1_0_DEVICE_ID (0xabcd) #define QCA988X_2_0_DEVICE_ID (0x003c)
I'm fairly savvy with linux and with command line stuff, but source code is not my strong suit. I'm sure I'm not the only OpenWRT user like that as well. Any way you could share a walkthrough on how to install the Ath10k drivers?
Or is this just a waiting game for the new kernel to be developed?

Hmm? I thought the mailing list said 1.0 will not be supported?
By 1.0 shouldn't it be refering to this?
#define QCA988X_1_0_DEVICE_ID (0xabcd)
Did you click on the link and read the email ? 
http://lists.infradead.org/pipermail/at … 00021.html
Soon I will change qca98xx hw1.0 support to ath10k as unsupported and
later on I will remove hw1.0 support entirely.

Archer C7 does not have heatsinks

I think that waiting is a better idea for most ppl because:
- stability issues & functionality issues & speed issues (see bugs on ath10k mailing list, commits in git)
- development stuff (which ath10k stuff is in openwrt?)
Example dev stuff: There is a package compat-wireless that is used for wireless drivers. mac80211 in svn tree
compat-wireless (its called backports now) is from June (but uses linux-next). ath10k mailing list + ath.git was set up in July - obvious difference etc
complicated versions ...
ok all makes sense. only thing that confused me was this closed bugreport on OpenWRT development that seems to say Ath10k is already implemented. I wouldnt be surprised if I'm just reading it wrong tho

Cool. I'll just hang on a little longer than. I don't need 802.11 ac today but maybe by end of this year.

When I try to use the method in post 63 to flash my tl-wdr7500 I get the error code 18005 "Upload file version does not match with the models." Is there any way around this?
Hi, I'm don't have a TL-wdr7500, I have a TP-Link Archer C7.
You should try to upload your firmware with TFTP.
Greetz,
Kris
.... just for the thrill of it I flashed the original TP-Link firmware using LuCI and it worked without any problems.
Hope this information is useful.
#jayrock
be very careful not to flash a firmware that contains bootloader (if it will ever exist..)..

May someone help me, i locked myself out and now i cant login neither via webui or telnet, i figuered out that no failsafe mode is possible?
What do i do, exept to knock my head against the wall every damm second...?

If youre locked out and failsafe mode is impossible, you're probably going to need to try the serial route. The hardware page for the Archer C7 has a few pics of the pinout on the board
looking forward to a build that could be flashed to WDR7500 via official web GUI
hi, Guys, may i ask what your /etc/config/network is? after i compiled a image by selecting ap135 board, the system can successfully boot. but the wan port cannot get ip from upper link and the lan ports doesn't give any ip to the clients. Looks like the router is working like a switch, because the lan clients can get ip from upper link instead from the router. In the first place i though that the dhcp server is not running on the router. but when i connect through wifi, the wireless clients can still get lan ip from the router. the following is my network setting:
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fd40:798a:7adb::/48'
config interface 'lan'
option ifname 'eth1'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
config interface 'wan'
option ifname 'eth0'
option proto 'dhcp'
config interface 'wan6'
option ifname '@wan'
option proto 'dhcpv6'
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'switch0'
option vlan '1'
option ports '0 1 2 3 4'
config switch_vlan
option device 'switch0'
option vlan '2'
option ports '5 6'
and my wireless settings are:
config wifi-device radio0
option type mac80211
option channel 11
option hwmode 11ng
option path 'platform/qca955x_wmac'
option htmode HT20
list ht_capab LDPC
list ht_capab SHORT-GI-20
list ht_capab SHORT-GI-40
list ht_capab TX-STBC
list ht_capab RX-STBC1
list ht_capab DSSS_CCK-40
config wifi-iface
option device radio0
option network lan
option mode ap
option ssid OpenWrt
option encryption none

vubvub, check post #38.

Thanks for your help.
i tried the method in #38, however, the br-lan is always 192.168.1.1,
the eth0 can get an ip (192.168.0.100) from the upper linked router, the lan client also get another ip(192.168.0.102) from the upper linked router.
seems to me that all the switch ports are through.
HI, Guy, I am new to openwrt, it will be nice if you can share your network and wireless settings. Thanks
Has someone allready made a ssl / openvpn Benchmark / Performance test?

It seems the problem is not from the settings. In the boot log, i don't see the loading of ar8327 driver. IF anyone know how to add it in menuconfig? I have already tried to add all Atheros drivers in there, but nothing changes. Thanks please give some help.

I did some experimenting and now I am a little bit confused with ath10k ...
1. update wireless driver package
package/kernel/mac80211
from compat-wireless-2013-06-27.1.tar.bz2 to
to (project was renamed) backports-20130712.tar.bz2
DL - see: http://drvbp1.linux-foundation.org/~mcg … backports/
updated the package ( see wiki, involves program "quilt" )
removed 300-pending.work.patch (afaik these are other fixes upstream or not yet commited in older versions of backports or openwrt exclusive patches i dont think they are affecting ath10k)
2. created,flashed archer c7 firmware image
ath10k isn't loaded per default : entries in modules.d are missing
insmod ath10k_common - no problem
manual loading results in Kernel Oops
insmod ath10k_pci.ko

Shouldn't MSI be enabled because of :

Another strange Log entry - is it related ?
[ 0.080000] ar724x-pci ar724x-pci.0: PCIe link is downIsn't this a PCIe card that other devs removed from their router and put to use with normal PCs ?
The wireless card in archer c7 is a V2 (168c:003c) and it should be fully supported with ath10k
Edit: ... some time later ...
I did have a look at a diff of ath10k git and the backports source of ath10k.
I searched for pci.c - because the "pci sleep" stuff was part of the Oops message.
I found:
+static void ath10k_pci_device_reset(struct ath10k *ar);
+static int ath10k_pci_reset_target(struct ath10k *ar);
+static int ath10k_pci_start_intr(struct ath10k *ar);
+static void ath10k_pci_stop_intr(struct ath10k *ar);
(and other stuff relating to intr(..) functions)because the Module init has no MSI-X or MSI it gets to default to INTR before it crashes so those missing stuff might fix it ...
There could be a new backports release but the git tree of the maintainer:
https://git.kernel.org/cgit/linux/kerne … ports.git/
is currently at 3.10.4 when stable is at 3.10.7 since yesterday. So that road could take a little while longer

If this works,I want to put it to some actual use.Where is the driver of qca9880 for windows? ：）
I wouldn't trust the PCI ID to identify the hardware version. My Archer C7 v1.0 definitely has a QCA9880 v1 despite a PCI ID of 168c:003c. I'm pretty sure that TP-Link has to make a new hardware revision of Archer C7 if/when they start to use QCA9880 v2, since it will also need a different router firmware due to a different chip firmware. I think I'll try to return or resell my unit...
How can you detect a QCA9880 v1 board ?
I just noted differences on the chip itself :
QCA9880-AR1A NFH090.002C 1251 - Archer C7 my unit
QCA9880-AR1A NFH090.001C 1251 - Archer C7 ( http://forums.overclockers.co.uk/showth … p=24424655 )
QCA9880-AR1A NFH089.00C 1248 - TP-Link WDR 7500 ( http://wikidevi.com/wiki/TP-LINK_TL-WDR7500_v2.x )

Hello,
I just got this router (C7) and started experimenting with it. Since I have no use for the ac-wifi card, I wanted to replace this with a mini-PCIe CDMA modem using Qualcomm's MDM6600 chipset. On another machine I have, running Ubuntu 13.10, the only driver needed for the card to work is serial-option, as the modem exposes itself as a USB device and creates two ttyUSB-devices. USB modeswitch is also needed.
However, when I connect my modem, it is nowhere to be seen and in the log file (dmesg) I see the following messages and the modem does not appear:
[ 0.080000] ar724x-pci ar724x-pci.0: PCIe link is down
[ 0.080000] registering PCI controller with io_map_base unset
[ 0.090000] ar724x-pci ar724x-pci.1: PCIe link is down
[ 0.090000] registering PCI controller with io_map_base unsetThe lspci-output is also empty.
If I leave the original WLAN-card in the router, everything works as intended. dmesg only contains one of the "PCIe link is down" messages and lspci displays information about the WLAN-card.
My question is, has anyone experienced similar behavior or has any tips on where to start looking/what to try? Is there something limiting me from connection other mini PCIe-cards to the router? I use the most recent trunk build (19th August).
Update: After doing some digging, this looks like a driver issue. I tried with some more mini-PCIe-devices and some work, while others do not. The common denominator between those that do not work is that they are exposed as USB devices. I have tried with the CDMA modem (identified as usb device 2692:9005 by my Ubuntu machine) and a Sierra Wireless LTE modem. When looking at lsmod on my Ubuntu-machine and comparing with the OpenWRT the output from the OpenWRT-router (with any of the PCI devices inserted), I can't see any obvious difference.
Thanks in advance for any help,
Kristian

AR1A are v1 chips.
BR4A are v2 chips.
Looks like ath10k may not support Archer C7 until they update to v2 chips.
There are two other routers based on similar HW.
Sitecom WLR-8100 and ZyXEL NBG6716.
http://wikidevi.com/wiki/Sitecom_WLR-8100
http://wikidevi.com/wiki/ZyXEL_NBG6716
If someone could open their router, then we'd know if they are v2.
Then maybe there will be better luck getting OpenWRT to work on these HW.
I just opened up my new Archer C7 labeled with HW1.1 (TP-Link HW) and unfortunately it was an AR1A chip in there as well.

The number after the dot denotes a software revision; it's just a model with a newer firmware pre-loaded. What we want to see is 2.0.
