Does someone of you have a degrading and variable/unstable 5GhZ performance and ping?
My speed would vary between 8mbit and 500Mbit download and 20-100 Mbit upload even though i don’t change the position.
The ping is between 6ms and 100ms. Even when i stand in front of the router.
Also the wifi is even unusable for some time because 0 throughput.
This problem sometimes goes away after a few minutes and I get the fullspeed and low ping back.
No errors in the system or kernel logs.
Not yet. My Windows PC connects via 5 GHz and everything is perfectly stable.
Are you sure that the device does not switch back to 2.4 GHz in your case? (By choosing different names for the SSIDs for example)
Yes, i disabled 2,4 GhZ on the router.
Its interesting that with the disabled 2,4 Ghz the router does not crash at all for me. It seems like it doesn’t like 2 wifi bands with the same SSID and when clients roam between both wifi connections.
I think most problem country code WiFi or 2.4 ghz conflict number channels🤔
How many clients do you have concurrently? It looks like my routers 5Ghz WiFi becomes slow with more than 10 clients connected and being active.
~10 as well - but they don’t use much traffic.
Since Wi-Fi is time- and frequency multiplexed, it’s totally normal that it will get slower if there are more devices. And if not all devices speak the same Wi-Fi standard it will be even worse.
it slows down with only 10 clients? wow… my old flint ax1800 flyes with more than 30 clients connected on it… if this is true it means flint2 is a massive fail… at least until they’ll get fixed all these issues. for the hardware flint2 has, 60-70 (maybe even 100) devices shouldn’t be a problem…
Depends on what the devices do. If they are idle most of the time, you can add as many as you want.
Wi-Fi is a shared medium.
around 6 are used for streaming (at this very moment i have 5 of it using iptv - so high demand of bandwidth and cpu) plus 8 cctv recording 24/7 on a local NVR. so figure it urself 
CCTV recording using Wi-Fi? Phew, Ok. Hope they have backup recording on SD or sth like that.
well… in total i have 16 but for 8 of it it was not possible to get it through ethernet so…
my wifi is rock solid (2 x Flint AX1800 as WAP, 1 Flint AX1800 as router - wifi disabled). it took a lot of tweaking to get it stable and very well performing but it is achievable
i’d say a decent performance
I can confirm that the Flint 1 aka AX1800 is also super stable, at least with firmware 4.2.1.
4.2.1 is the best firmware until now. 4.2.3 is good but introduces few minor bugs (also wifi performance drops a bit), 4.4.6 has a lot of issues (even marked as stable is very unstable/wifi is horrible), 4.5.0 seems to be ok (on wifi side) but i need to test it a bit more. if i’d be glinet management i’ll leave on the website as the last stable fw 4.2.1 and 4.2.3 as beta (i would completely remove 4.4.6).
23 clients at the moment. result: I connect with my smartphone and its stuck on checking for internet access, which means the WiFi is totally unusable.
And I’m standing in front of the router with a full signal.
I also tried my laptop, the same “no internet” and I can’t even ping the router via WiFi.
If i restart the WiFi interface via OpenWRT (LAN) then all is fine again for a few hours.
Via LAN cable i never have any performance problems.
All I do is running an open 5GHz network (with wireguard)
One of the most basic things this router should be able to do.
I even flashed an OpenWRT snapshot firmware, which has exactly the same problems, so its somewhere rooted in the WiFi drivers.
I never had this problem with the Flint 1 and I’m really considering to send my 2x Flint 2 back.
If you set a static IP while using Wi-Fi, does the issue still exists?
I also have this same problem with only 2 clients connected, but doing a teams web conference. After 2 hours of conference, can’t access internet on any website and no new clients can access the router. The funny thing is that the conference still goes up.
@admon I have to try it out, but i’m getting an IP by the DHCP server. I really wish there was an error message in the system and kernel logs, but there is nothing.
I hope this is only an error by the driver design.
I know that the Banana Pi BPI-R3 shares the same CPU and chipset (but slightly different WiFi chipset) and unfortunately also the same WIFi crashes when using 2,4 and 5Ghz with the same SSID, which I mentioned at the beginning of this thread.
I will have a look into the Banana Pi community and see if the BPI-R3 also has the same 5Ghz issues.
But the LAN connection is still working fine?
I didn’t test LAN clients
Did you remove version 4.5.4? Did you find any other serious bugs that needed to be deleted?
Yeah not only is 4.54 for the Flint2 not there (I’ve been running 4.54 for a week without issue)…
But also the Flint1 they now removed everything except releases going back to September and earlier
after they had just released an updated beta firmware for the Flint1 yesterday…
I flashed that one to my Flint1 last night and woke to find they removed that and are now offering only firmware from September and earlier. Some clarification would be nice.
