Since no one has posted between your post and your quoted post, you could have used edit post instead of quote your own post.
If you’re using CRS as a switch with configuration that allows full hardware offload, then you neither gain nor loose anything by upgrading. So far it was not shown that v7.1 exposes any new feature of switch chip which would potentially prompt for upgrade.
Well, you get numerous bugs (some may not bite you though).
Given the time between post and edit it makes more sense to make a new post.
Otherwise others might miss the edit.
My view…
That l2mtu tip was given to me by the Mikrotik support, but, I don't know if this also affects the RB4011, which is my main router.
today my hAPac2 crashed, after rebooting it lost all the config.
On the RB4011 I'll stick with rc2 for now
update, manually restored configuration, and config survives reboots.
config gets erased whenever updating, restoring rc2 or importing rc2.
Great question. I’m also annoyed by removal of “routing-table” argument from ping and traceroute. Why is this removed??
I would like to request a separate smaller wifiwave2-package for cAP ac, hAP ac2, … i.e. all devices with IPQ4018/IPQ4019 chipsets which could be possible:
- As the new combined wifiwave2 package contains several firmware files, libraries and linux kernel modules for different chipsets the file npk package is quite big. With its 10MB it is not possible to install it on current devices with 16MB of ROM, e.g. cAP ac, hAP ac2, new wAP ac, … If you split that package you could also install on devices with 16 MB of ROM:
- Regarding the RAM requirement, I have to note that my cAP ac device shows over 80 MB of free RAM, even when 30+ clients are concurrently connected. So I assume that there is plenty of RAM left for using the new wireless firmware and drivers on IPQ4018/IPQ4019 devices which have 128 MB of RAM installed. Has MikroTik tried to simply modprobe the inbuild modules for IPQ4018/IPQ4019 at all? What went wrong? Which limitation did appear?
There’s something weird with the marked area in my screenshot - long number is most probably in bytes, as the label, but the GiB in the end is wrong.
This is captured on Winbox 3.30, on an Audience running Wifi Wave2 7.1 rc3.
Loosing configuration after reboot (7.1rc3)
and other people write the same to me at Telegram that loss of power can start unit from default config
@anuser judging by the sizes your screenshot shows, 4019 would just fit in a flash of a Cheateau. I have have 2100kb free space. Not much left then.
Prolly RAM limitation, ath10k requires 256MB RAM for two radios for proper functionality.
OpenWrt barely runs on these units with a patch to reduce ath10k-ct RAM consumption but it’s not usable for anything else than basic router/AP functionality.
ros7.1rc3 + winbox 3.30
does not accept and save “::/0” as allowed address in wireguard peer configuration (GUI)
but with command line its Ok
Does OSPF work properly with this release?
In future, will be a version of wave2 which fits in cAP ac etc?
With 16Mb flash it didn’t fit, even the new product cAP XL ac has only 16MB and 128MB of ram? Is not mean to have wave2 package?
Also, on website is written that cAP ac is IPQ-4018 based and has 128MB of RAM, but i’ve logged onto my AP and it says its IPQ-4019 based and size of memory is 256MB? Winbox shows wrong values?
I have tools to desoldier and swap chips to have in ex. 32MB of flash, but does board recognize it?
You are one of the lucky. When hAP AC2 (and looks like cAP too) was lauched, Mikrotik had problems with supply. So, the first (or firsts?) batch used the IPQ-4019 instead, and came with 256MB of RAM. The official spec is 4018 and 128MB of RAM, but some people got lucky. 
It’s the same ipq4018, just more RAM.
ipq4018 can’t be replaced with ipq4019, requires a board redesign.
Due to the lack of WiFi 6 products from Mikrotik, I bought a cheap Belkin RT3200 and flashed it with OpenWrt.
It’s a big upgrade from my Mikrotik hAP ac2, now I have proper WiFi and better coverage at home (higher spatial diversity due to 4x4 MU-MIMO).
I haven’t performed iperf3 benchmarks yet but my Galaxy S10e shows 1gbps link speed within the same room as the router, OpenWrt also allows to use up to 160mhz bandwidth but I don’t have 160mhz compatible clients to test.
is not the competitor of the upcoming MikroTik cAP ax which will use IPQ60xx chipset. Current low cost competitors with the same chipset family nowadays would be:
- Engenius EWS357AP
- Grandstream GWN7660
Both can be purchased for < 100$
MikroTik doesn’t use the opensource Ath10k driver but the OEM driver from the chipset vendors I assume.
My hAP AC2 is a 4019 with 128mb…
