Throttle is nothing more than limited or allowing a limited amount of bandwidth even though your paying for more Data etc. They throttle ones connection because you're getting to close to your limit or you've went over your usage limit. System dump or FlushDNS would be suggested. It's like paying for a 32GB ram chip and when you scan the chip, there 10% data already on it which can't be removed.. So what are you really paying for.
One other issue is that when one used wifi or bluetooth, you're system is inundated with unwanted searchers or sniffers. Depending on how secure your system is, it weather or not anyone can pull up in front of you home access your system and use the wifi etc. I'd be thinking of going hardwire instead of wifi
