I didn't have problems before changing to the wireless last week. But even after it worked fine for some days. But 2 days ago I suddenly couldn't connect anymore. I didn't make any other changes. I tried with port forwarding, and it worked for one day. But today I can't connect again.
Please help me, I don't know what else to do

The settings in your router are probably reverting back to default. There are several routers that will do that for one reason or another. You may have to set up port forwarding again and again etc. Some times new firmware will solve the problem.

But if they were set to default I wouldn't see them in the router setup. But everything is still there.

That may be true but I have had to reset mine numerous times when the settings were still there. I would just try updating them and see if it helps.

I have tried that using different ports. First it didn't work. But then, out of nowwhere I could connect. But when I tried again tonight, it didn't work again.
Maybe I just have to wait and be lucky.
Thanks for your help
