Using it for many years already,  regular firmwaren updates , very pleased with performance

Router thread
https://forum.lowyat.net/topic/4658096

can,if the router has VLAN settings.

Just go ahead.
I think, did you change channel?

Full bar but no internet access, it will be others interference with your 5 GHz wifi, this happen because they are using 800M etc, 5GHz only got 443, or x2 with PC 2:2 antenna.
Even got 160 MHz which is taken all the channel, lol.

Try ping when no internet access, if can ping but high latency, it means interference.
If can't ping, it means router issues like hang.

And yes, old device like very old phone low performance connected to router, will also hang the others.

For checking wifi channel is this.

Yes, also just wonder, what's the performance of fiber modem, fiberhome?
So far I got huawei, then they switch to ZTE after huawei banned by US, both works well.

For router, nah, can use, but if I heavy on WiFi will down real quick, only suitable for 30-100M usage.
And orange router latency higher than AC1200 v2 with NAT BOOST.
DNS?
Can be a dns issues, which also handle by router for caching and reroute to ISP DNS.

Yes that also count as router too shitty lol.
And yes, good router with auto channel selection should select based on talktime, not just default CH 36, lol.

Unsure which website you means, YouTube got local MY peer server(aka TM and Maxis etc lol), so unless you means Twitch or Bilibili, If YouTube stop loading, sure is local network issues.

Ya, then more likely local network issues, I will try ping first la.
Using a Laptop is easier, just wifi connect, open 2 CMD windows.

1.
ping 192.168.1.1 -t
2.
ping 8.8.8.8 -t

First one check for local router, second one check for Internet, got history so can refer back when your smartphone no internet, just stand up and take a look on your laptop , then you will know which is the fault.

Adding another PC with cable also can rule out it is router hang or WiFi hang.

If you lazy, just switch over Asus's good router model, done lol.

Wake me up when September ends.

21 days left.
