just to follow up on my journey..
so i bought TPLink Archer GE800 (GE not BE) on 12.12 ($594)
setting it up was FAR BETTER experience than HB810
everything feels right, fine and working...
added both HB810 as satellite node in easymesh WORKING YES!
basically Aginet router sucks, just repeating this..
to be fair, the hardware is good.. the firmware and UIUX sucks..
I noticed you have an issue with the 2.4Ghz band. I have a lot of IoT devices that I do not want on the main network and Easymesh does not extend the IoT or Guest networks so my IoT devices far away from the main router have a very weak signal. There is no solution using Easymesh, so I have a separate $20 Xiaomi range extender just to extend the 2.4Ghz band. No doubt the speed by the time to repeat the 2.4Ghz signal is 5-10Mbps, but it's good enough for IoT devices.
to reply to this, easymesh does work as mentioned above..
with the above setup, i now have ethernet backhaul from GE800 to both HB810 on 2.5G port
(10G port from GE800 direct to my PC, pending my 10G PCIE card to arrive)
now the whole 2.4Ghz network seems ok.. since i have 3 nodes coverage now..
in the whole journey, i learnt that 2.4Ghz nowadays seems to have super bad speed..
despite showing full bar on devices, it can go to 0.1mbps on speed test when going too far..
on the same distance, 5Ghz and 6Ghz actually still works fine..
i kinda guess there could be 2 potential reason this.. just my guesses
1. 2.4ghz band is having more and more interference in current era
2. router starts to focus on 5ghz and 6ghz band more
the remaining problem i still have, which i believe is a firmware issue..
the HB810 altho its just a satellite node.. the 6Ghz and MLO band of the HB810 doesnt work on easymesh
the default Singtel-CXXX_6G and Singtel_FXXX_MLO SSID still broadcasting by default
this problem exist even when im on the HB810+HB810 setup as mention in my earlier post..
this problem should be between TPLink and easymesh.. but the tricky part is our HB810 is Singtel's firmware..
so to hope there's a firmware patch for this.. really need to wait long long i guess..
reflecting on possible ideal solution..
actually a GE800 or equavalent (or non Aginet) as the main controller..
with wifi7 ethernet backhaul enabled easymesh extender (not avail yet i believe)
will be the ideal cost effective solution..
