I too have the ac68u and ac86u. Both on merlin. Even though the 86u has double the RAM of the 68u, the 86u consumes much more ram. Up to 95% ram utilization if you have a usb media hdd plugged in. To mitigate that issue, I had to configure a swap file.
Daily, my 86u shows a bunch of notices/warnings in the syslog because I have a few wifi smart things in connected. I had to install custom scripts to suppress/workaround those warnings.

I never got those issues when the ac68u was my main router.

Where I noticed the 86u performs better than the 68u is the wifi range and faster usb transfer speed (and possibly openvpn). Even when overclocked, my 68u is still about 20-30MB slower than the 86u in usb 3.0 transfer.

Overall, I think the ac68u is the better router for the money. A trouble free, solid performing router even to this day.

Back to topic; I'm stuck on 175.143.xxx.xxx even after numerous router/port resets. Intermittently extremely slow speeds, even Amazon echo lags badly when executing commands. On a couple of rare occasions, Spotify would breakup mid streaming. Curiously, google home is not impacted by this.

i'm still getting 4k hdr on netflix, though amazon now is only giving me 1080p

perhaps it's just your area

1:52pm
twitch live 1080p60, netflix 4k hdr ok here

If you're trying to achieve a 500Mbps speed test on 2.4ghz in your room, you can't. Even standing beside your wireless router, the best you will probably get on 2.4ghz is about 150-180Mbps in a real world situation. That's the limitation of 2.4ghz
With 5ghz 802.11ac you could potentially get 500Mbps but I'm guessing the 5ghz is too weak in room because all the walls in the way?

If you want to cover your whole home with good wifi signal, you might want to look into a mesh wifi system.

A cheaper alternative is to convert an old router to a wireless AP, place it upstairs and run an Ethernet cable from the main router to that wireless AP.

If running a long ethernet cable is not an option, then you might want to get a pair of powerline adapters + wireless AP

Unless there are issues with your fiber modem and router, IMHO I don't think replacing those devices will significantly boost your wifi signal.

you enable and input the ipv6 dns in your main router
and enable ipv6 on your pc

it's a scam. report it or ignore it, your choice

I feel your pain bro... being stuck at home for weeks with only mobile data for the internet

Years ago when TM first came to install/setup fiber at my place, I noted the login they used. To access the Huawei ONU, TM had set my laptop to
IP 192.168.100.2
Subnet mask 255.255.255.0
Gateway <blank>

login:Telecomadmin
pw: admintelecom

If you could find a kind neighbor with a Huawei ONU, you might be able logoin and to copy their ONU password using the settings above

Hopefully it's a just the power adapter that's broken. Test is with a multimeter and if it's the culprit you could buy a replacement online

same, shopee and twitter extremely slow.

ip 175.143.x.x

did you have ipv6 enabled? 3 posts above yours, sHawTY who's in the same ip range as you says Shopee loads instantly

repeating heLL_bOy's server tests but with FDM because i don't have IDM

i still can connect to expressvpn and nord servers. i was watching hunger games on youtube earlier with vpn.

which vpn are you using?

i'm unclear what you're asking but here's my speedtest to a random sg server whilst connected to a sg vpn server

ya 300mbps unifi

this seems about right if the lyra trio is connected the ac68u via wifi.

if you're running a speedtest from your laptop/iphone on 5ghz to the lyra, i'm guessing the lyra then connects to the router on 2.4ghz which as you stated gave you max 80mbps

to get best speed, backhaul or connect the lyra to the router via ethernet, set ethernet as your preferred connection in the ac68u aimesh settings, then run your speedtest on 5ghz

if you like to stay with asus, depending on your budget, how about the ax56u or ax3000?

whichever router you go for, i think it might be best to go for one that has ax routers even though you may not own any wifi6 devices atm for a little bit of "future-proofing"

if you can turn off the 2.4ghz, the lyra will basically become a 5ghz repeater - meaning half the original bandwidth with each subsequent hop because the bandwidth has to split equally for receiving and transmitting
