[edit: 07.March 2021]:
Router Model: Ubiquiti NanoStation M5
Firmware Version: DD-WRT v3.0-r45863 std (02/28/21)

Hello,
I would need you help in configuring my dd-wrt in such a way that the current connection stay's stable with the AP.
Application:
I would like to connect with the router to an eduroam network close by.
Therefore I set-up the 5Ghz network in the attached Wireless Client mode
Issue:
The router connects & gets a connection for a short periode - but after a few seconds (below 3 min) the connection is lossed & a re-connection will be performed.
I tried several thing to build up the connection in a stable way - but I struggle.
Therefore I uploaded the screenshots of Wireless Mode-Client configuration incl. the advanced settings & also the information of the AP situation.
The wireless security page is also attached where I hidded my personal information.
Can someone support & help me to get a stable connection ?

Sorry to miss some information in the inital post:
Router Model: Ubiquiti NanoStation M5
Firmware Version: DD-WRT v3.0-r45863 std (02/28/21)
Kernel Version: Linux 3.18.140-d5 #108144 Sun Feb 28 02:03:01 +07 2021 mips
Problem:
I think I do not meet the right configuration for the 5Ghz "client mode".
I adjusted the following values in the "wireless settings":
Changed Wireless Mode to : N-Only
Channel width to : 20Mhz
But as I'm not an expert in the the "wifi advanced settings", I'm still struggling with the settings.
Tried to "play" with the following values:
- Threshold - increased to 1250
- Beacon Interval - increased to 577
- DTIM Interval - increased to 2
- Sensitivity Range (ACK Timing) - set to 0
When I'm connected I achieve the following values:
Signal : -56
Noise : -95
SNR : 40
In the syslog I receive not a lot of information, which I can use for further analysis:

There is no information about connection drop etc. so it just searches by its "own" for a new AP. Why?
Unfortunately I do not achieve a stable connection & cannot really find out why the connection drops.
Based on the Spanish Exchange I have the feeling that maybe there is an issue with the Client Mode + some frequencies (even if the hardware in there is a nanostation m5 xw)
Additionally there is something I do not understand:
Status > WAN - provides me the information of a connection uptime >5h again:
Status > Wireless - where I see that I'm roughly connected over a view minutes.
