I recently switched from Cogeco 14 mbps service to Bell 6 mbps service. It is significantly cheaper, obviously, but I am having several problems. With the modem they gave me, I had connection dropping several times. They sent a new one today, and there have been no dropped connections so far. I have installed filters at the required spots so that shouldn't be an issue.
The main problem, however, is that webpages take a long time to load. This was never an issue with cogeco, and it shouldn't be an issue with a 6 mbps connection. They take a long time to load, or they show that the internet is not connected. Not always, but very often. If I refresh the webpage a few times they show up.
The funny thing is that internet does not get disconnected while the pages don't load, because some of the times while pages have not loaded, I have been downloading files and the downloads still keep going (and for the tech people, no the downloads don't "stop and "resume" because the file size keeps increasing, i.e. the file is still downloading).
OTOH, cogeco prices are kind of high and their bandwidth policy is of ridiculous. This is also my experience with Bell so far and some people have had much better experience.
