ASUS GS-BE 12000- random internet disconnections

Ernesto305 — Tue, 21 Apr 2026 17:23:30 GMT

Router: ASUS GS-BE 12000

Modem: BGW320-505

We switched to the ASUS router from an amplifi gamers edition. We also have AT&T fiber 1GB plan. It has gone amazing , however, the biggest pain point has been random disconnects , usually solved with unplugging both router/ modem and plugging back in. Works perfectly no issues and then randomly , could be a day or few days later, the same thing happens. Have to reset router/modem and works like nothing has happened.

Below is the last few days

4-2-26: WiFi network showed no internet connection. Router/modem reset. Issue solved.

4-6-26: WiFi network was working, randomly disconnected from my phone and I had to go manually and reconnect to to my network. Internet was working.

4-10-26: WiFi network showed no internet connection. Router/modem reset. Issue solved.

4-11-26: WiFi network showed no internet connection. Router/modem reset. Issue solved.

4-21-26: WiFi network showed no internet connection. Router/modem reset. Issue solved.

Mind you, this is just for April. Happened a few times in march (router purchased early march)

And each instance is one time, it hasn’t happened more than once on that date.

Any ideas what this could be?

I saw your post on SNB Forum, and responded... The moderators here are actually ASUS employees so you'll get exposure to them...

One thing I thought of since my post:

You shouldn't have to reboot the BGW320-505 gateway. (At least I don't have to reboot the BGW320-500 gateway). But it is a different model I think yours is made by Nokia and mine by HUMAX...

Whatever you do don't mess with the fiber stuff... It is unbelievably thin and fragile...

I asked Chat and it stated based on my logs it could be a band steering bug

If you feel that may be the issue, (as I think owner input/opinion is highly important without physical access to see what is happening), you could change each band's SSID to unique names, and enable WiFi Agile Multiband on all. See if that helps...

any router you recommend as an alternative for a 1G network?

Well, it's more of what suits your needs what to choose. But the GT-BE98 Pro is a solid quad band platform that offers solid high wireless speeds far above your 1Gb ISP connection. It also has two 10G Ethernet ports and four 2.5 Ethernet ports. I use two of them and they each deliver excellent coverage.

With current prices that I just checked, Amazon lists your model at $399.99. Right now I checked BestBuy and the AFC equiped GS-BE18000 is cheaper at $369.99. I can't promise it will run better on 2.4 and 5 GHz because it has matching specs, but AFC does help on 6 GHz and I do not think the GS-BE12000 has it....

ASUS routers have been sensitive to issues at the WAN port/WAN side. But AT&T has been a reliable service provider, even my prior local Cable Modem company Giggle Fiber. Currently my main router which is situated above the BGW320-500 gateway, I turned off 5 GHz band, and turned on WiFi on the BGW320. The range of 5 GHz on the gateway is great, and it is also WiFi 6 vs your Amplifi WiFi 5. I don't know if you also have AT&T cellular service but I had to turn on the BGW WiFi to connect to it, to provide backup WAN source....

I suggest you also try turning off 5 GHz on the GS-BE12000 and turning on the WiFi on the AT&T gateway. Also for each of the three bands on the BE12000 turn on WiFi Agile Multiband. (This is IF it is too late to return the router and get the better GS-BE18000 from Best Buy)....
