Internet 150/150 with T3200M but lousy connection

[wireless]

A Telus guy just installed a T3200M modem for my 150/150 plan. I have a newer laptop with Intel(R) Dual Band Wireless-AC 3160 that can only connect to the 2.4G because the 5G is invisible. It takes minutes to load a single internet page on both my cellphone and my laptop. It says it's loading and once it's done there is just a white internet page, and the images and the rest follow a few minutes later. I cant even run a speed test because the page freezes/stops loading. I have reset the modem both by unplugging it for 30sec and by factory resetting it with the reset button at the back. I have restarted my computer and turned off wifi etc. When I plug in the Ethernet cable and change to Ethernet settings there isn't any difference in connection performance. I just opened task manager and looked at the wifi throughput and I dont receive any more than 120kbps. Its an 802.11n connection type and I dont have a router. I even tried changing the network channel to 11 but no change.

Any suggestions?
