I didn't know where to put this, but I recently (approx 2 months ago) found my wifi speed drop from 180mbps to 21mbps. After days of working through solutions and trying everything, I called out the Shaw techs (Aiden) and in 5 minutes he found the problem. A Dell upgrade loaded the program SmartBytes. Killed my wifi speed. We removed it and I'm happily humming along wirelessly at 180mbps again. TELL EVERYONE! Get rid of Smartbytes if you're having speed issues... Save yourself some serious headaches and time!! Thanks Aiden!!
