Gaming on gigabit internet fluctuations in speed

[wireless]

So I'm not very knowledgeable on internet issues but what I do know is since I started with telus I have the same problem and that's unstable speeds on my internet and possibly packetloss at times.

I have done my best to troubleshoot all this and every conversation I have with telus I'm told all the tests come back perfectly fine, but at the start of multiple games I get packet loss and latency symbols. Someone suggested port forwarding but seems like I'm not able to do this without a buissness account also we have optik tv so another router may not be possible.

I would like a tech to come out but numerous conversations have telus reluctant to send someone as they don't see a known problem. Appriciate any help.
