Internet 150, but slow uploads even with hardwired connection

[wireless]

Wondering if any one has ideas on what could be the issue with my slower upload speeds.

I went to fiber and got internet 150 on October 31. Since getting fiber, i've been running a number of tests on both wifi and hardwired connection.

From October 31 until November 12, i was receiving download/upload speeds on both wifi and hardwired of around +170/170 mbps.

But sometime around 4pm on November 12, the upload speeds on both wifi and hardwired connection significantly dropped to only 44% its max capabilities. I consistently get download/upload speeds of +150/66 mbps. Going from +150 --> 66mbps on upload is a significant drop.

I thought it may have been due to a migration issue on the back end - since a tech i had indicated the first contractor had forgot to call in the migration - but thats a long story), so i did call Telus tech support to see if they can verify if everything on the back end was migrated or programmed correctly. Today they phoned me back to confirm that there no noticeable issues on the back end with my account.

What could have changed within a day that would have caused such a significant drop in upload speeds?? Nothing was added to my network. Could it be the modem itself? the ONT? my ethernet cable?

I currently use a T3200M and i also have a Web6000q extender.

Any ideas would be appreciated. Thanks
