@plemans Thank you for answering, the wierd part is that it's fine instantly after i restart it then i get full speed again and staays like that for days, if it was radar would i still have the same speed after my restart?
@plemans I'm testing this on 3 devices the results are the same.
My 3rd Band wifi 4gh-2 where i run WiFi 6 on the 128 channel i onlye have once device assigned, when i first noticed the issue i added more devices to test, same result max speed of 200mbps, restart router full speed on my Desktop full speed on my mobile what it now supports around 600mbps, i use speedtest to test my speed.
So for exampel right now.
Open SpeedTest website on the Desktop thats on the WiFi 5ghz-2 128 channel = Speed caps at 200mbps
Move the desktop device to the WifI 5ghz-1 running on channel 42 i get 900mbps.
Repeate steps with Mobile result change is only due to mobilephone supports 600mbps opn Wifi 2 200mbs caps out on wifi 1 600mbps.
Restart router.
For 2-5 days i will have maxed out speeds at 1200+mbps on 5ghz-2
I can do the same test on multiple devices iPads, laptops all the same, only the second 5ghz band gets this issue.
I can try changing the channel but i dont think that will help at all as i dont have any radar issues on that channel it's more of a degration of speed over time on the band.
@plemans I dont know how long i had this issue, i mean i dont notice much as i dont use much bandwidth on the device or very rarley.
I have done factory reset, restored settings same issue.
I will try changing channel but I dont think thats the issue as the speed gets instantly back after one reboot, but channel is the only thing different from the other bands right now. If i move the device to 5ghz-1 i get 900mbps+ while on the 5ghz-2 on channel 128 i get 200mbps after a couple of days, so i guess the channel is the only part different if there is no firmware issue with the second 5ghz band.
This is not an channel issue this is most likley a firmware issue on the second 5ghz band using DFS channels.
Other 5ghz band speed stays the same, secon 5ghz band speed drops and caps out at 200mbps always. After a reboot speed is 1200mb+ wait for a couple of hours speed drops to 200mbps.
Why would it impact all? They send data over different channel if one channel has radar interference then maybe yes it would drop speed. But that does not explain the issue on all channels as all channels does not have the same interference?
I did notice that even if you set a channel and save it then for some reason the first time it still stays on that channel when i scan WiFi, like settings does not apply even after reboot, config says channel 116, scanned WiFi says Channel 124.
Currently i have been had 1200mbps+ on channel 112for 1 day now.
The second band 5ghz-2 can only use DFS channels i cannot select any other channels then DFS here. But again i thinks this is firmware as the radar would shutdown if someone was broadcasting, i even checked laws in my country, scanned for inteeregence etc no onne in this area is using DFS channels. Speed is 1200mbs+ when a reboot happens or when i change the channel and radar scans again, beetwen hours it will then be capped at 200mbps, i mean always the same stable connection but 200mbps this does not sound like interference to me, then that number would variate and my latency to.
@plemans I dont have any active radar here, my channel stays on dfs i dont get dropped down, speed gets capped at exact 200mbps.
I check my channel settings and everything. I also use WiFiInfoView application to check channels etc.
For exampel i set the channel to 116 in my settings, but the channel is not 116 when scanning it's 120 for some reason, and this keeps happening like the settings is not really doing anything.
I don't want to drop my rate and not be on DFS channels due to latency issues. I dont have any latency issue on the DFS channels, the wierd part is the speed drops not latency or anything else. speed gets capped at 200mbps after a couple of days or hours, restart router speed is back.
Just to be clear, i have also tested this now on a Zyxzel Armor G5 that has the same chip as the RAX200, i have yet to have any issues here so i have to wait a couple of hours/days to report back. But my point here and please correct me if I'm wrong, if the channel settings is not respected then thats an issue, if the DFS channels works perfectly after a reboot but later on speed gets capped at 200mbps always this number. Is this due to radar used on the DFS channel? Wouldent the router not allow me to run on the DFS channel instead of lowering speed? I have check we do not us anything to broadcast on the DFS channels, and i have scanned my entired place no one or anything is using the DFS channel except me.
Need to reboot for WiFi speeds to stay high, lasts beetwen 1-3 days on DFS channels.
There is also another bug present. If you select a DFS channel it should go down for 10minutes, it just does not do this more then 80% of the time i can switch DFS channels WiFi stays on channel switches (Channels does switch have scanned to see that it actually switches)
A reboot gives me 1gb after 1-3 days its 400-500mb or lower, reboot again instantly goes up to 1gb speeds
