Dynalink WRX36 - sporadic wireless clients ping issue

otnert · August 1, 2023, 11:54am

OK, I'm at my wits end here! trying to get the WRX36 to behave correctly.

If this is a widespread issue, everyone would be reporting it, so I feel my config might be incorrect?
note: I did have the same config on my Archer c2600 which worked faultlessly.

I've noted my experiences here:

Generally - cannot ping devices that I should be able to ping, eg: devices within the same br-lan.
All devices are wireless.

Current running 23.05.0-rc2, r23228-cd17d8df2a
At the moment, wireless 2.4G devices are replying to pings from a 5GHz client, whereas all 5GHz clients are not replying to pings from the same 5GHz client.

I say at the moment, because it's sporadic, e.g. upon a reboot / flashing new image / changing wireless setup / etc, will change which devices that are replying to pings/not.

Can someone give me some guidance before I lose all my sanity?

Can you manually try the following (when pinging doesn't work):

echo 1 >/sys/class/net/phy0-ap0/brport/hairpin_mode
echo 1 >/sys/class/net/phy1-ap0/brport/hairpin_mode

And then test again?

otnert · August 1, 2023, 1:21pm

Thanks @zekica for the help...

I think they're already set to 1

root@OpenWrt:~# cat /sys/class/net/phy0-ap0/brport/hairpin_mode
1
root@OpenWrt:~# cat /sys/class/net/phy1-ap0/brport/hairpin_mode
1
root@OpenWrt:~# echo 1 >/sys/class/net/phy0-ap0/brport/hairpin_mode
root@OpenWrt:~# echo 1 >/sys/class/net/phy1-ap0/brport/hairpin_mode

however, I did run them then disconnected 2x 5G wireless clients, reconnected with no change.
BTW, I'm running a total of 4x SSID's, 2x are guests and they are set to 0

root@OpenWrt:~# cat /sys/class/net/phy0-ap1/brport/hairpin_mode
0
root@OpenWrt:~# cat /sys/class/net/phy1-ap1/brport/hairpin_mode
0

Just to add I can ping the wireless clients using cli, yet from a Windows wireless client...

ping using hostname

Who is 192.168.2.222?

sppmaster · August 1, 2023, 3:10pm

Please check this too.
Maybe related somehow. The setup is simple.

Turn off windows firewall?

otnert · August 1, 2023, 11:44pm

Windows PC (ACER-Aspire.lan) where I conduct the pings from.

It could be but I'm not 100% sure.

When I get no ping replies it's not for a few seconds. e.g. this morning I cannot ping any device on the 5GHz band. I also couldn't ping 1x device on the 2.4Ghz band however rebooting such device brought it back.

I don't think it's a windows firewall issue, e.g. if connecting via 2.4GHz this morning I can ping and access the shares on that windows PC, with 5GHz no ping replies, no shared access.

otnert · August 1, 2023, 11:58pm

OK here's another issue which hasn't occurred before...

ACER-Aspire.lan on 192.168.2.222, shows up as a guest network IP 192.168.3.222

ubus call system board; \
uci export network; uci export dhcp; uci export firewall; opkg list-installed; \

I see some other posts are indicating issues with the ath11k driver on other routers. I would be tempted to load dnsmasq-full and wpad-openssl instead of the defaults. I would be tempted to disable all ipv6 if your ISP doesn't use it.

Thankyou @frank92735 for looking into this for me, I appreciate it.

If there is anything incorrect in the output above, please let me know, I'd want to test one step at the time to home in on the issue.

Pls advise on the correct method to install these packages

already in network config, would this suffice?

config device
	option name 'wan'
	option ipv6 '0'

First make a back up of your configuration (save archive). Next you can either try these steps or just skip to the end and try a factory reset instead - that's up to you.

system>software>update lists

type dnsmasq in the filter input field
click on installed
it shows dnsmasq (as per the opkg list-installed previously done)
click remove and then confirm by clicking dismiss
select available and install dnsmasq-full
dnsmasq-full is a larger more comprehensive package.

Reboot and test router. Can 2.4 clients ping 5ghz clients?

If not then do the same thing for wpad and replace with wpad-openssl. wpad-openssl is a larger more comprehensive package.

Reboot and test router. Can 2.4 clients ping 5ghz clients?

If not do the same thing for libstream-mbedtls20201210 and replace with libstream-openssl20201210.

Reboot and test router. Can 2.4 clients ping 5ghz clients?

If this didn't fix it you can do a factory reset and verify the package list is back to initial conditions (or add remove as necessary) and then upload the archive and then you are back to square one. Hopefully someone else has some ideas.

Good. Now also do the same for LAN interface via LuCI: interfaces>LAN>advanced settings tab and disable "delegate IPv6 prefixes".

Do the same for the wireguard interface via LuCI: interfaces>wireguard>advanced settings tab and disable "delegate IPv6 prefixes".

Optional: This may interfere with other VPN services. I like to disable peer DNS and force WAN DNS: interfaces>WAN>advanced settings>use DNS servers advertised by peer= disable. Then enter custom DNS. I enter my wireguard provider DNS server IP here or whatever you like.

otnert:

config wireguard_wg0
	option route_allowed_ips '1'
	option endpoint_port '1337'
	option persistent_keepalive '25'
	list allowed_ips '0.0.0.0/1'
	list allowed_ips '128.0.0.0/1'
	option endpoint_host '1xx.xx.xxx.xx'
	option public_key 'xxxxxxxxxxxxxxxxxxxxxxxxxxx='

It seems odd to have 2 entries for list allowed IPs. I just use 0.0.0.0/0.

Also there is no wireguard DNS listed - use DNS from the VPN service provider from the config file they give you.

option auto = '0' The wg iface is disabled?

What is this? Unused? Old syntax from previous router?

If you transplanted those config files from your old router into the wrx36 that may be the source of all your woes.

Barring any suggestions from other users I would factory reset the device and reconfigure from scratch via LuCI using the default packages. Sorry, it sounds like you have been to hell and back. Once you get this one up and running I recommend you buy a second wrx36 for testing purposes so you don't affect your main network.

Reagrdiong:

I do it too to preserve the default route it is actually what OpenVPN does by default and also a lot of other third party firmwares.

regarding

That is to signal to e.g. PBR you have this openvpn interface

I do agree maybe reset to default and start fresh could help, but there are also some wifi driver problems reported and under investigation.

There is an option in the wifi to isolate wifi clients from each other so isolation can be something which is/can be done on the wireless driver

OK so I followed your instruction
1/ removed dnsmasq

install dnsmasq-full...
Configuring libnfnetlink0.
Configuring kmod-nf-conntrack-netlink.
Configuring libnetfilter-conntrack3.
Configuring dnsmasq-full

reboot
2G<=>5G OK
5G<=>5G Destination host unreachable

2/ removed wpad-basic-mbedtls

install wpad-openssl...
Configuring wpad-openssl

reboot
2G<=>5G OK
5G<=>5G Destination host unreachable

3/ removed libustream-mbedtls20201210

install libustream-openssl20201210...
Configuring libustream-openssl20201210

reboot
2G<=>5G OK
5G<=>5G Destination host unreachable

4/ disabled 'delegate IPv6 prefixes' on both lan & wg0 interfaces
reboot
2G<=>5G OK
5G<=>5G OK! OK for approximately ~1hour then Destination host unreachable

I have the VPN wireguard/openvpn DNS listed in wan section...

config interface 'wan'
	option device 'wan'
	option proto 'dhcp'
	option peerdns '0'
	list dns '10.0.0.243'
	list dns '10.0.0.242'

That's how my VPN provider rolls, Yes I'm aware of 0.0.0.0/0 though.

frank92735:

option auto = '0' The wg iface is disabled?

frank92735:

Not disabled, only Not started on boot, as I have a script which brings up wg0 / tun0 via a cron job.

That just it...
I started from scratch barebone install, left the dhcp / network / firewall / wireless and config files intact, then added packages and only adding snippets of what I thought was safe to add to each config.

The majority/backbone of each config file is intact, i.e. I haven't just transplanted everything over from the TP-Link c2600.

I'll keep the config how it is for the time being, let's see how this pans out.
Thanks for the help @frank92735

My hunch it's a WiFi issue, and it seems the latest WiFi drivers (WLAN.HK.2.9.0.1-01837) addition has caused more issues. Looking back I think 4 days on the old driver, was about the most time without error, with the new driver I had immediate issues.

frank92735 · August 2, 2023, 1:16pm

Nice catch. I also forgot to advise @otnert to uci export wireless. Ooops sorry!

Roll back and watchcat/cron every 3 days?

egc · August 2, 2023, 1:24pm

I went back to 1835 see: Ath11k possible firmware bug - traffic interruptions when a client disconnects from WLAN - #18 by egc

With that build I had no trouble pinging from my phone to my laptop (both on 5 GHz, 80 MHz see above) but the other way around from laptop to phone I got some strange results it starts with host unreachable but after some 4 pings it started to work with ping times alternating between 4 and 400 ms.

Turns out the phone is on very aggressive power saving, if I run a ping test from the phone itself to the internet to get it up and active I have consistent ping times from laptop to phone of 4ms.

Have not investigated how to disable the powersavings on the phone, there might be a setting on the router to do something in that department, I think

Haha I was going to show it to you anyway!

Since the c2600 has a switch config, and the WRX36 DSA, could you just take a look at the guest components in network, dhcp, firewall & wireless. Just want to make sure I did that correctly, and it isn't contributing to this ping issue.

As an end-user it all seems to work.

Yes I have this set for both guest SSID's

otnert · August 2, 2023, 1:57pm

Yes! so did I (just between posts)... as the same ping issue started to occur using the 01837 rc2 version.

It's strange that if you where to change from 5G to 2G and pinging the remote 5G host, the ping issue disappears. From here if you then move back to 5G, to ping the same remote 5G host it somehow resets the 5G ping issue.

The problem is not knowing how long before the 5G connection will remain in a working condition.

Just before moving over to 01835, my remote PC went to sleep, upon waking it from sleep, the issue appeared again.

Yes I also have 2x androids, and as soon as the screen goes blank, it gives you the impression the ping issue has started. I run a speedtest on the phone to wake it up long enough to ping it.

egc · August 2, 2023, 2:10pm

It is even possible that a wifi client disconnects after a period of inactivity so you cannot ping it at all unless you wake it up. So that makes it hard to see what is going on and where the problem lies, my quick test did not show a problem but that is what it is just a quick test.

To be honest I seldom have wifi<>wifi traffic as my house is cabled, of course phones and tablets are on wifi but PC's and laptops are using ethernet
