Poor internet quality going on for several weeks now

Hello, I am not the one whom has the contract with TELUS but she is unavailable atm so I made this account to try and get into contact with someone who might be able to help, I have restarted my machine, I have restarted the router for a full 60 seconds, I'm not sure what else I can do, I use a wireless connection but I have the signal booster or whatever its called in my room with the computer that is connected to it, it is not blocked its has free line of sight with the wifi antenna, but my internet quality has been garbage for weeks now, major packet loss and constant disconnections to the game servers, and I have checked the status of said servers and no one else has been reporting issues with them. we have if I recall correctly the plan we are under is the purefibre internet 300. I'm just frustrated because it was good for a long time but for the past couple of weeks its been nothing but lost connections and massive ping and packet loss spikes. maybe the infrastructure around my house got damaged somehow and that's what's causing? there has been a fair bit of construction around my neighborhood. I don't know. But I do know there has been a massive degradation in quality to the service we pay for.
