Question

[Laptop] Upload not working over WiFi, only over LAN

Apr 22, 2017 3:54AM PDT

Hey! So I've run into some network problems lately (Well about a month now, maybe more). It all started, with me not being able to connect to a game server. It was only for that one game and I assumed that it was a problem with the game. But after HUGE connection issues with other games too (after ~3 weeks after the first incident(I didn't touch the game and only tested in a 2 day rhythm, if it worked again)), I started testing around. I came to the conclusion that my upload was not working AT ALL over WiFi. I tried connecting the Laptop over LAN and it worked like a charm instantly. So now my question is, how I can fix that problem. I have a FRITZBox router (I can't access the fritz.box website over WiFi either(neither over the link, nor over the IP-adress)). I tried resetting all my network drivers to the point, where I first got the Laptop in November, but with no result. The odd thing is, that the upload works in other WiFi networks except in mine. I tested it in 10 other WiFi networks (of friends and family) and it worked in ALL of them. Thank you in advance for the help. I'm curious what is wrong and if I can fix it.

Since it works on 10 other WiFi networks.

I think that's a great test and my diagnosis is something's funky with the WiFI in the Fritz box. Change that!

Change what exactly?

I posted this in another forum too and got the answer, that it could be because of port forwarding. Define "funky". What else can I do apart from deleting all my forwarded Ports? (Wasn't using them anyway, so I got rid of them all to make sure it's nothing with forwarded ports)

The Fritz box.

Your story tells me the laptop is fine.

Now if you are forwarding ports, I can't know that. I start as if it's a stock untinkered as-supplied by the ISP device. If you tinkered, put the router back as it came and re-test. If 10 other WiFi spots work and yours does not, then this Fritz box is suspect.

I deal with a lot of networks and in 100 home networks, not one forwards ports. I would be guessing why you are doing that. And I don't guess.
