Note that if you have Power Boost on your account the speed test might be a bit inaccurate because theres no cap when testing the download bandwidth - its like a constant flowing water so thats why the number is large.
If you are experiencing slow speed, try the following first before you contact Shaw:
-bypass your router and connect straight to modem (bypass hardware firewall and other hardware influences)
-reboot computer in safemode WITH NETWORKING (by tapping F8 when restarting) to bypass all software firewalls/trojans
-run various speed test and log the stats, running speed test in normal windows mode can be very inaccurate sometimes
-If you dont have any sort of protections on computer, it is HIGHLY RECOMMENDED that you try a free online scan on the various anti-virus websites to make sure you arent infected. Also download the free trojan scanner
http://www.malwarebytes.org
It can detect lots of hidden spywares/trojans that regular virus scanner cant detect. I had a slow speed customer calling me before and he end up finding 40+ infected things after a full scan.
-What kind of modem are you using? skinny little black Motorola is the newer/stable one. If you have the old blue Terayon, bring it to shaw retail and ask for a free swap!
-Call Shaw's 24 hour support and ask them to check if there is any maintenance/outage in the area.
-If all looks good but you are still getting slow speed, ask them to check for any modem "packet loss" (abnormal bandwidth loss when transferring data) or area "saturation" (area bandwidth has reached its limit)
