Weird Client behavior with rt-ac88u

Evening Gentlemen , I recently bought an rt-ac88u never before had a router other than those cheap ones the providers give away , I went on with the purchase since I am starting some smart home hobby and opted for a good starter point with the router.

I started with the stock firmware everything was fine until I tried to pair a broadlink RM Pro+, this one is only 2.4ghz b/g/n band only, so I disabled smart connect and pair it with the 2.4 but soon after I experience disconnects on the device, I fiddled with some more settings I found recommendations here but didn’t work out so I flashed the latest firmware (384.15) and followed L&LD post for noobs ;)

I made a new ssid (seperate 2.4 and 5 ) I paired the broadlink but same results afterwards I tried disable airtime fairness , preamble type short , disable universal beamforming , multi mimo off , wireless mode to N only and 20 MHz channel bandwidth , every time I changed each option I let the broadlink on until it disconnect nothing works

Now the weird part for me since I am a total noobis it allways disconnects at exactly 1 hour been on ,the tx/rx rate drops to 1 and one minute later it drops for 5 minutes every time!

One thing that seems to work is enabling Guest wifi and putting it there alone ,now it runs for several hours without any problems but I think it acts with great latency.

Any help appreciated !

Try the legacy setting and leave the a/b check mark alone.

I had a Vivint security system and had cameras and stuff dropping off all the time. I spoke to an engineer and he said use the legacy setting to use the lower "g" standard. He was right it worked and really 54mb/s was more than enough for my cameras.

Thanks @skeal turning on legacy did help , it is running for 12 hours no dc's!
Allthough now i am thinking if i should let the broadlink to the guest wifi and put back my normal 2.4 ghz to N , since running legacy wireless mode disabled many other features in professional tab and every other device i run was doing allright anyway.
Reading in wiki that the legacy mode has weaker signal made me thinking if i should go that way , i cant confirm the weaker signal my self though,and airtime fairness and universal beamforming should be disabled anyway from the suggestions i read here .Having a guest wifi running without really using it apart from that device should not caus any delays-interference to my main 2.4 ghz wifi is this correct?
