Port forwarding isn't a solution as this isn't a port forwarding issue. Nor do you need a business account to port forward. Tech support for home accounts just doesn't offer help with setting up port forwarding. There are MANY discussions on the forums here about how to do it. Also, if the connection itself is working fine and it turns out to be your computer/console that is the issue, if a tech did come out, they'd likely charge you for the visit.
Too many questions come up about your post. I'll start with the following. Please provide details:
- How are you determining "unstable speeds"? Games do not need much bandwidth/speed to operate.
- Is it just on one device or multiple?
- Is it only in games or are other programs affected?
- Is the device you are using connected to wireless or ethernet?
- Which OS/console and which game title(s) are affected?
- If you're on a PC, which graphics card do you have and what version of Nvidia or AMD drivers are installed?
- Which game server(s) are you connecting to?
- Possibly packet loss? Have you checked to see if you are actually experiencing packet loss and not just high latency?
- When you say "latency symbols" can you elaborate? Are you talking about pixelation or other visual artifacts? Or something different?
- Do they only appear when you first launch the games and not after you start playing?
