At first I thought it was the sites,but then I noticed the wi-fi signal is all over the place.
When on one bar the pages freeze on the screen until it goes back up to 2 or 3 bars.
This problem started when Telus put in the new modem saying it was faster than the old model,but so far slower which I assume at this point to be the Telus wi-fi signal.
Wi-Fi can be variable, and if it drops to one bar, then little or no data is being transferred, and pages will freeze. Can you describe the location of the router, your computer or other device and a little bit about the structure of your house, as all can affect wi-if signal. If you have a larger home, the addition of an access point may improve signal strength.
It is always better to connect to the router by an Ethernet cable if possible.
Wired is ALWAYS going to be better, as there are no interruptions or interference to the signal, as can happen with Wi-Fi. Just about every device I can attach by Ethernet is so attached to my network.
The modem identification name is on a sticker near the rear of the modem. The newest model is T3200M. Is this your model?
Now that you know you've good connection speeds when hardwired, there area few more considerations. Firstly, can you connect most of your devices by Ethernet, as it it the better option. Wi-Fi can get overloaded by local devices, and neighbouring Wi-Fi signals or other interference, such as microwave ovens.
Have a look at the number of other Wi-Fi signals surrounding you to get some idea of the potential for interference. Mine looks something like this:
