How to stop rsync overloading your wireless/LAN

I am currently using rsync as a backup solution between two computers and an external backup drive, all operating across my wireless LAN. However, every so often - and always when syncing a lot of files - rsync has knocked out my wireless internet. Today, I decided to find out what was going on, and found the solution:

bashrsync --bwlimit=500 ...

It turns out that rsync was overloading my router with data, causing it to reset the connection. Setting a bandwidth limit (in kBPS) to one nearer that of the router prevents overloading, and allows the scripts to complete.
