AsiaRF AW7915-NP1 / 802.11ax / WiFi6

I am not good at giving deadlines or even schedules. :wink: But 6.0 will be soon merged to HBL still w/o support for Turris 1.x. It requires more digging up.
On the other hand, the community and we will have the opportunity to try new things, focusing on them, giving us feedback, fixing it, etc. We will have time to polish it and to ensure that the upgrade will be smooth for most users. But don’t worry, we will announce it.

I would suggest to fix problem with not working wifi cards after switching to HBD before moving to HBL. :wink: Except this problem, everything went ok on my Omnia.

Installed …

Could you post the output of sensors after some time of usage?
My constellation is

01:00.0 Unclassified device [0002]: MEDIATEK Corp. MT7915E 802.11ax PCI Express Wireless Network Adapter
02:00.0 Network controller: Qualcomm Atheros QCA9984 802.11ac Wave 2 Wireless Network Adapter

I added a slidely oversized heatsink to the MT7915E and get the following values while normal usage situation (2-3 devices connected, no filetransfer running):

mt7915_phy0-pci-0100
Adapter: PCI adapter
temp1:        +61.0°C  (high = +120.0°C, crit = +110.0°C)

ath10k_hwmon-pci-0200
Adapter: PCI adapter
temp1:        +64.0°C

So I believe in heavy usage scenarios (which I am right now to lazy to design and test) both might reach higher temperatures. So it would be wise to move one the 5G-card to slot 3. Let’s see if values drop significantly. Yet this is no option with a SSD installed to slot 1 (for my second TO I therefore bought an external housing for the SSD, aloy-block-heatsinks that are in touch with the TO housing and will install an additional fan on top of the TO housing to make sure temperatures stay cool).

So you actually replaced with old Atheros card in one slot probably for 2G band. My setup still consist of one primary Turris 1 that I use for all network connections due to following reasons:

  1. TOS6 is not yet in stable branch
  2. I had not migrated all services and configurations yet. mainly LXC may need to update config but also plenty of other things will likely need to be reconfigured or newly configured due to different config files syntax (that’s what I suspect)
  3. Asiarf AX cards could not now broadcast 2 another SSID in 2g band as they can for 5g and I don’t know yet why. (I use 3 SSID’s for 1. regular network, 2. guest network, 3. TOR network) in 5g it worked out of the box in ax mode, for 2g it does not work in ax (had not tried ac yet)
  4. 5g ax signal level drops very rapidly and even speed is not yet as I expected even when ax notebook is nearby just few meters
  5. most iportatnly even though I have now 2 ax noteboox and 1 ax phone I still need to connect older ac devices notably ax phones tablets and notebooks that simply does not see the ax SSID on 2G ax network and even when they see 5G ax SSID it is impossible to coneect to ax network.

So for now I just done initial setup and made it running somhow but it will take some time to find best configuration setup and it will need more time. For now I did not even put the heatsinks on the cards as temperature is not an issue now for me.

Exactly. For me high throughout is negligible compared to coverage but 2,4 GHz in 802.11g and 802.11n modes doesn’t offer MIMO. But the other issues you encountered with 2,4 GHz are unfortunately of concern in my eyes, so I will have to look into them.

Hm…
This might explain why I have connection issues in one room. As I planned one single ax-card for my allotment I’ll have to look into that later, thanks!
Btw - 802.11AC is for 5 GHz band only.
Did you have a look into syslog?

Those cards do not need the heatsink - even without it they report a critical limit of 110°C (which I believe could damage them already). But could you please do a temperature check before applying them and after the router has been running for a couple of hours? Would be nice to have comparison-data.

I can confirm my observation that on 2g N mode or 5g AC mode 3 SSID are broadcasted but not in ax mode in 2g band. Which command to check the temperature ? I could try to make some test. I don’t think that temperature of 110°C could damage cards.

Temperature can be checked with sensors.
I used the wrong wording - it will not directly damage them. But with those temperatures normally capacitors and other parts start to wear out.

Do you have latest wifi drivers for your devices, especially notebooks?. One of mine did not see AX network, but after drivers update it can see it and it can connect to it even when the wifi card is max AC only.

My temperatures with heat sinks are:

mt7915_phy0-pci-0100
Adapter: PCI adapter
temp1:        +59.0°C  (high = +120.0°C, crit = +110.0°C)

mt7915_phy1-pci-0200
Adapter: PCI adapter
temp1:        +70.0°C  (high = +120.0°C, crit = +110.0°C)

In my case (4 SSIDs on 2,4 GHz AX) the devices definitely see the SSIDs, but they can connect to only one of them.
So that would have nothing to do with client drivers, right?

For drivers I hope so. I exchanged wifi card in older laptop recently with AX210NGW and Intel driver download utility updated drivers to recent one. Seems heatsinks does not make much difference.

Hi, it is a bit off-topic but sensors doesn’t list any pci device. Device is TO2020 (5.3.3), I have 2 wifi adapters and 1 msata SSD.

In case of ath10k (WLE900VX and WLE1216v5-20) you need to have ct-driver and firmware installed to get temperatures displayed.
But, yes, it is off topic…

It depends on many factors, so it is hard to compare exactly. At least ambient temperature, air flow around the router, cpu load, wifi load, wifi card position according to CPU, router case size…
In my case, there is NAS-perk (bigger router case), that means 2x 2,5" HDD under router mainboard, which produce some heat too.

I have intel 7260 card in one of laptops and it is able to connect to both AX networks (2,4 and 5GHz) after drivers update.

So after testing and using 1 card in a Turris Omnia on HBL-branche for several days now it seems very stable to me.
There are devices that are not compatible with its 160MHz 5GHz-SSIDs, but for those I am providing a second non-AX 2,4GHz SSID (which is anyways still necessary as some devices out there do not support 5GHz at all).
Yet in terms of connection (ping/stability/speed) itself I do not see differences between the WLE1216v5-20 and the MT7915E (maybe my laptop itself is that far outdated being from 2017 that I will never reach gigabit-speeds wirelessly with it), so I will keep them in my MOX-APs.

These cards are working with HBL? HBL is still not TOS 5? I thought it is working only with TOS 6, which is quite stable in my case.

Have a look here: OpenWrt 21.02.1 is coming into HBL branch
So: hbl is TOS v6

I have read that, but didn´t noticed it is already in HBL. So it is time to switch to HBL. :slight_smile:

Hello, I don’t know what your old 2017 laptop is but I had been able to easily upgrade my old HP Elitebook 840 G2 with this AX card from aliexpress Tri band Intel AX210 wireless AX210NGW 5374Mbps 802.11AX wireless Wi Fi 6 AX200 AC9260 8265 8260 7265 7260 3168 3165 3160 M. 2|Network Cards| - AliExpress
If you can dismantle your notebook and exchange wifi card it is definitely option.
