Problems correcting to certain internet sites through Wifi

[wireless]

Good morning everyone. I have a problem that started yesterday - I can only access certain websites via Wifi through my portable devices (android tablet and smart phone). This is really annoying as my TELUS Security app won't connect properly. The problem doesn't occur when I go through a wired connection on my laptop, so it must be something to with Wifi.

Thanks.
