Hello,
after implementing the recommendations from my last post about the issue, I still have stability problems and I am not sure how to debug them, as the syslog does not contain anything meaningful.
What I already tried with any success:
1. Upgrade to two Archer C7
2. Several different firmware versions
3. Different Wifi channel (even if no other wifi is in sight)
4. Remove repeater temporary
5. Setup papertrail syslogd, to have the log after a reboot
Would be super thankful for any kind of ideas.
Setup:
1. AP1 - (WAN = Internet route)
2. Repeater to extend Wifi of AP1
3. AP2 to extend Wifi of AP1
Do you see anything in my configuration which I could change/improve in this?
I still have hope, that someone could give me some hints where I can look at in addition. I would also like to see exactly what the problem is (e.g. the key rotation).
Ubiquiti would be the "throw money to it, to solve the problem"-solution. But they are quite pricey and this would violate my honor as a Master in CS .
I have a very stable connection between my routers. In the summer I run a bunch of routers all set up in WDS. Usually uptime is greater than a week. Then a new dd-wrt build comes out and I upgrade.
PS: I did just notice an error. You selected WPA, not WPA2 on the WDS Station. That would cause it to drop out. Also, HT40 and WMM are required for Wireless-N speeds. SFE - Shortcut Forwarding Engine, personally I disable it. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.

Thanks, adjusted it accordingly and will let you know if it is more stable now.

Just to address the stability issues, I converted from "client bridge" to WDS several years back. I find it the most rock solid, stable setup I ever used. I sometimes wonder if it ever breaks. Like ian5142 I cover about 5 acres. I rarely ever drop a signal. My tx and rx errors are zero. I see others have had had issues with many recent builds so I`ve stayed behind for that reason. I run a remote log at a station just to look for ANYTHING ! Honestly it just timestamps and handshakes here ! I use Archer C7 ver.2s and TL-WR841ND ver.9s. with no issues.
It looks that the WDS is now more stable using 5GHz, but way slower - assuming due the bad coverage.
I have the opportunity to get an Archer C7 V4, should I replace the repater by a third archer? This will improve the signal for sure, as the repeater is more or less in the middle of both archers right now.
Any concerns having a version 4.0 archer?
The W2 chipset is the same, according to the wiki.

5GHz is fast if your close by but doesn't do well if your going any distance or thru a lot of walls. I use 2.4 only on my setup but I have a station that is 500 feet away. I get about half the speed of my AP at that distance. But its very stable.
That is my physical setup.
I just replaced my Repeater with AP3 (Archer C7).
In the ideal case the wifi routing is as follows:
AP1 (www attached) -> AP3 -> AP2
My question now:
The new AP3 in the middle, should it be
1. only a WDS Station or
2. Daisy chain it as described here? Means AP3 needs to be WDS Station + new virtual interface as WDS AP, which AP2 joins as WDS Station?
Update: mixed WDS AP with Station

Just to throw this out there:
From your picture --- technically they will work that way but probably should be:
AP1 = WDS AP
AP3 = WDS Station + a VAP on it as WDS-AP for clients and for AP2 WDS-Station to connect
AP2 = WDS Station + VAP on it for clients
of course if AP3 & AP2 can reach AP1 ok it would be best to have both as WDS-Stations connected to the AP1 WDS-AP and then create regular VAPs on them for clients or use other radio band if dual band router. And if possible it is always best to have multiple routers wired setup as WAPs .... any that cannot be wired, a regular WAP can also be a set WDS-AP or WDS-Station
The connection from AP1 and AP2 is not so good on 5 GHz, therefore I wanted to replace the repeater with AP3.
I want to use the 5GHz for the WDS connections between the AP1-3 and 2.4GHz for the clients.
Only speaking about the WDS 5GHz:
AP1 = WDS AP
AP3 = WDS Station
AP3 = WDS VAP
AP2 = WDS Station
I have to create a virtual interface on AP3 to act as a VAP.
But when I do so, I don't see the new TAB for Ath1.1-WDS. Do I have to use the Ath1 WDS tab for enter the mac addresses or is it a bug?
