We installed the Shaw Gateway system and, after an initial hiccup, it works great. The follow up service was excellent. While it might be coincidence, we've noticed our internet service seems to have been impacted negatively. Takes way longer to load a page, etc. Tried running the Shaw Speed Test and I got yellow triangles with an exclamation point in them. Finally got a DL of 20.71 but never did get an upload speed. Any idea what's wrong?
