I see the same problem with my work laptop, which has Ultimate-N 6300. Upstream bandwidth was 450 Mbps, downstream a lot smaller. This on Ubuntu 13.10. Which OS do you run on your laptop? I was thinking it could be an issue in the Intel wireless linux driver, or in ath10k. I bring rarely my laptop home, so I haven't debugged the issue further, by checking speeds in Windows 8, for example.

I'm running Windows 7 64-bit. I used taskmgr to check which speed the card reports on the Network tab - it only showed the lower value (100-200), so I doubt I could have hit 450 upstream. It sounds to me like an ath10k problem considering I hit full speeds with the Intel card on a WNDR3700.

I too am on an Intel card and the 5ghz is pretty bad. I'm getting almost the same throughput as paladine. Also while I can get WDS to work after a fresh boot of the device now, at some point over hours, or days WDS eventually stops working. This is what I get for jumping into a draft standard

Man.Did I not make it clearly or you didn't read my post carefully?I has flashed a archer-c7 v2 firmware downloaded from tplink.com into my wdr7500-v3 which is modded with 16m flash w25q128.But I think I need an art from archer-c7 ver2 to replace the orignal art of wdr7500-v3 to get that freaking tplink firmware to initialize without errors.That shows. in my post #385.So someone who has an archer-c7 ver2 please follow my instruction at #385 to extract the art and put it on any online storage service for me to test.

Then I suggest you contact tplink for support, because that is outside of the scope of openwrt forums.
Further, I don't see anything in your logs that even HINT at there being a problem with your ART data, so diving all the way in and swapping that out with someone else's private serial numbers is definitely premature.

How do you reflash the stock firmware? OpenWRT's luci flash page won't accept the .bin file downloaded from TP-Link's site.

Hi all,

Could you help to check if the 7500 v2 have a EJTAG port on board?

Thanks.

拆机贴也不发一下,又要别人帮你,注意自己的素质,看你也是把V3已经拆开了,就不会拍个照片放上来?

You need to remove boot block from it.
dd if=tp-stock-firmware.bin of=new-firmware.bin skip=257 bs=512

I of course meant with the OpenWRT and I meant to say Archer C7 V2, not WDR7500 V2.
Is anyone successfully running OpenWRT on Archer C7 V2 with the ac fully working?

WDR7500 V3 coming.

V2  VS  V3
http://img.mydigit.net/Mon_1405/88_2724 … ad.jpg?236

Something different from WDR 7500 V2  and  ARCHER C7 V2 .
The Flash only  8Mb, and the 11ac chipset is on the board,not module.

Hi Wuxeon,

V2 in "V2 VS V3" means Archer C7R or Archer C7 v2.0?

I really need a board which has EJTAG port.

Thanks.

Well, that's one way to reduce expenses.
Unless there are additional differences, it should work fine with the c7v1 builds, including 5 GHz.

你没事找抽啊，上不上拆机图跟素质有什么关系？这机型跟archer c7 ver2几乎一样，网上有拆解图，wdr7500v3的图也有了,我发帖就是为了刷上英文官网固件看看ac好不好用。我现在这台机器ac中文固件链接不上，刷了openwrt也不行。没想到还被骂一顿，真素无聊！

Why I think it has to do with art.Check this sheet

The 5g channels allowed to use in China is much less than US and Europe and different.Art control the initialization of wireless.Maybe the English firmware should meet a suitable art.
OK,I don't want to talk more bullshit.Someone who can email me his archer-c7 ver2's uboot and art.I will give 0.01 btc to thank for his/her help.

I got an archer c7 v2 yesterday and flashed barrier breaker onto it.  The ath10k-pci module from the kmod-ath10k package doesn't seem to work with it.  The package itself is dated from 2014-05-19 and it is on BB r40804.

dmesg gives me:

root@OpenWrt:/# dmesg  | grep ath10k

[  211.230000] ath10k_pci: probe of 0000:01:00.0 failed with error -22

I also found this bug report as well, which seems to be what I am experiencing.

Has anyone else run into this issue?  I was thinking that maybe I should clone the git sources and build from about a week ago or so.  From all that I have read, the v2 should work with the 5GHz band of this router...

Is it already confirmed that WDR7500 v3 also uses the new Atheros 11ac chips, that its 5GHz channel can be supported by OpenWrt?

Cheers.

I got these errors with my wdr7500v3,too.But my another device with qca9882 works perfectly with ath10k.

Hi all,

Sorry to ask a more basic question here, but today I upgraded to the latest version of barrier breaker (r40820) and my 5ghz radio is not being detected. I had this working before on the previous version. In my startup logs I find this:

Fri May 23 20:27:28 2014 kern.info kernel: [   12.220000] ath10k_pci 0000:01:00.0: BAR 0: assigned [mem 0x12000000-0x121fffff 64bit]

Running "wifi detect" "wifi status" only shows the 2.4Ghz radio. "iw list" also only shows the 2.4Ghz radio. I'm not familiar enough with OpenWRT yet to be able to fully diagnose this myself, so any help is appreciated.

Thanks

Edit: I did do a factory reset following the firmware upgrade.

Yes, OTP calibration failure is a known problem in the recent trunk. I'll look into it this weekend, unless someone else manages to fix it first.

Thanks for the quick reply! Just wanted to make sure it wasn't something I did.

I tried to build a ram image for WDR7500, but after I boot it with go command, the eth0 and eth1 could not be found.

checking my boot log, I found following lines are missing from a good boot log.
[    2.810000] ath79-spi ath79-spi: master is unqueued, this is deprecated

[    4.700000] eth1: Atheros AG71xx at 0xba000000, irq 5, mode:SGMII

I have build libphy and mdio driver as module, but it did not work.
Do I have to build libphy and mdio driver as internal of kernel?

Anyone...?

Cheers.
