hi @asusmy,

I jut replaced my AC66u with AC86U (hw v1.5) for my UNIFI 800 Mbps. It is running as per below:-

Firmware Version:3.0.0.4.384_45149
Not using smart connect (enabled seperate ssid for 2.4 and 5 Ghz)
Not using AIProtection
Not using AdaptiveQOS
Firewall : YES
DDOS : NO

Client : Mixture of smart devices (ipad, Android )

Questions
1. Sometimes, the wifi connection will just die and there is no internet connection. Looking at the device, the internet LED is still white. After a while, the wifi is back and there is internet connection

2. Looking at the system log, i noticed that this entry is quite common
- Feb 10 03:57:52 kernel: jffs2: warning: (13485) jffs2_sum_write_data: Not enough space for summary, padsize = -1913

3. A lot of disassociation is going on

Hi @blacktubi

Thanks for the suggestion. I have turned off the roaming setting (under Professional Settings) for the 2.4Ghz and 5Ghz

Will continue to monitor..

Hi sifus,

Need to ask whether I should upgrade my current asus rt-ac86u?

- 9 ppl at home with at least 2 devices per user (mobile + tablet/pc)
- unifi package: 800 mbps


Would upgrading to wifi 6 router (eg asus tuf ax3000) help to improve web user experience as most of them are streaming videos / online games / WFH and Home based Learning (zoom)?


Thanks
