New user of r49626 on Netgear R7800.

Following wifi setup here https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=324014

The parameter "Disassoc low ack" must be more recently added and is not shown in the guide.

I believe it defaulted to Enabled. I don't know what this option does and in researching it I saw a post or two that made me unsure what would be the best setting, one I think specifically mentioned R7800.

What do you recommend?

THANKS

p.s. Also, I am using Vanilla FW on both bands, FYI.

hmm...im not using it, but it means it will dissociate(kick out) any wi-fi client,
that is too far away(drop clients with low signal)...with low ack times...

drop clients with low signal has its own value too... Razz

you can fairly disable it, the downside is it will, keep looking and prob congest slow down the network in some way...as well good side is if you have a WDS or more wireless stations and client goes around and moves from one AP (wi-fi station) to the next AP..
I also guess, client and station must support it too, so transition will be better...

The feature(s) work best with default DTIM, BI, and using an ACK timing that is a multiple of 90, but you don't want to go over 900 or 1350 in most scenarios. It doesn't seem to be understood that the spec of 90 is with true line-of-sight, not spatial distances - or at least that is my understanding. I don't claim to always be right Rolling Eyes Wink

This is fimrware dependent.
ath10k with the vanilla firmware takes as a minimum 450m completely no matter what you set there.
on the tab Status > WLAN you can see that the ACK Timing changes only in 450m steps.

all values ≤ 450 result in 450
values > 450 result in 900
The default value 500 also results in 900

but according to the wiki article this is also true for ath9k:

https://wiki.dd-wrt.com/wiki/index.php/QCA_wireless_settings#Sensitivity_Range_.28ACK_Timing.29

but if you use the dd-wrt radio firmware you can also set other strange values

What does the source code and binary (ath10k and ath9k) firmware files say? If you're going to be matter of fact, show the facts, thanks.

The driver source code files are GPL and so is the entire DD-WRT source code tree (with some exceptions). Enjoy.

Thanks for the replies.

It seems that this option is way over my head so I will go with the default until I bump into a reason to change it.

Thanks again.

No idea who you want to troll here.

1. I said it depends on the firmware not the driver.

2. the dd-wrt ath10k driver source code is not public

3. the ath10k vanilla firmware source code is not public (even BS wrote several times in the forum that he does not have the source code!)

So if I would post here source code of the dd-wrt ath10k driver or firmware then I would get huge trouble either with BS or QCA.

There you see once again that posting 13.000 Posts does not make you an expert.

QCA is open source.

Then show me where in dd-wrt SVN is the ath10k driver used by dd-wrt.

Small hint this is not the used driver:

https://svn.dd-wrt.com/browser/src/linux/universal/linux-4.9/drivers/net/wireless/ath/ath10k

and Candela Tech is not QCA this is a custom driver and firmware from Ben Greear

This is a meaningless discussion, as far as I know BS uses specially adapted firmware which is not in the public repo.

So enough said about this Evil or Very Mad

Neither is kvalo, but to answer the initial question:

https://svn.dd-wrt.com/browser/src/router/mac80211

Everything goes to the public repo eventually, except for proprietary Broadcom code.

lol what?

Kalle Valo is senior software engineer at QCA

The thread can then be slowly closed.

Everything in the mac80211 driver code is updated and specific intervals, if you pay attention.

And all of his driver code, not firmware code, is copyrighted by the Linux foundation and Qualcomm Atheros, Inc. and is included in the mainstream kernel trees. So, you're saying that kvalo code *is* being used in DD-WRT with this comment. I think you misread my previous comment <wink><grin>
