Hello, I have been having some difficulties with my somewhat new router. Prior to yesterday, I had multiple ports forwarded and servers running on two computers in my house. They were working perfectly fine and users from other networks were able to reach my server from their computers, however now they cannot access the server. I believe this all happened when I setup my new powerline adapter so I can get internet from my lower floor to my upper floor. Then I went to run a few errands and when I returned the server was no longer working. When using external port checkers such as canyouseeme.org and yougetsignal.com and they have notified me that all of my ports are closed. I believe the issue is due to something with the router due to me testing my servers on multiple computers throughout the house with no success, I hope you can help me with this issue, thanks!

I get this problem every 3 months or so on a router that serves a high def camera system/NVR. The ports forward just fine for a while. I run QoS so the cameras have less priority on ports 85, 37777 and 37778.. I also allow the router to be open to remote config on port 8080.. All of a sudden, anything incoming it blocked. So, I reset the router to default and reprogram it all again. Such a shame, because this is a great router - with such silly little bugs... I'm also disappointed that it gets very warm and seems to be lacking processing power.. I really don't understand how it can take 1 minute to boot. Should boot and be fully functional in under 10 seconds, and not have any noticeable delay in going from screen to screen on the web...

I have had one of these for some time. For me port forwarding stopped when I applied a firmware upgrade. I raised an issue but the ASUS tech just implied I did not know how to set it up.

I am using firmware 3.0.0.4.270

This was the newest I could find where port forwarding worked. I have not tried recent versions. Just tired of the frustration.

I've had trouble with the older versions of the firmware randomly going into restore mode -- but the older versions of the firmware did seem to port forward. I got sick of having to cable connect to the router to get it out of restore mode so I recently updated to firmware 3.0.0.4.374_726. It's been more stable (no more random restore mode) and at first port forwarding was working --- but it randomly stopped working two days ago. I've not got anything special going on - just running a minecraft server for my son and the neighbor kiddos. Any ideas here? Thanks

It is like they are using the slowest onboard flash memory in the world, or need to bump it up to a much newer quad core ARM processor.

This.
packed full of features, awesome interface, very slick presentation. Too bad this is the worst router I've ever owned in the last 15 years.
If you stop reading here, know one thing : don't buy asus routers. They should stuck to mobos.
The router has a ton of pretty features and when it works like all things that work, it's good. The problem is this POS router can't handle itself for more than a few weeks before simply giving it up.
I see this with everything from wireless stability on both bands, but usually not both at the same time - but this router can't go more than, yeah three months sounds about right - three months before you have to reboot , reconfigure, and generally wish you had bought something else, which I am about to go do. Now all my forwarding just stopped. I mean, all of it. I went in to configure a port for the first time in probably a year, with no forwarding rules in the table, and as soon as I tried - boom, all forwarding dead.
Lost an entire day to this piece of garbage. I wish I had an asus engineer here to explain to me how "wong" i am forwarding a g-d port. Yeah thanks I think I can handle it. SOOOOO ANGRY
