How can I limit the bandwidth of a Guest SSID on our Wifi router?
I would need the model number of your Belkin router to know whether or not DD-WRT supports it, there are a lot of Belkin routers.
Hovsep's answer is exactly what I would do IF my router supported the DD-WRT firmware, however mine and many others do not. This is a complicated process and I would not recommend doing so if you're not comfortable with flashing firmware and resetting factory defaults.
From my experience, the most convenient and reliable way to throttle a specific system on your network is by installing traffic shaping software on that client's machine (see below). Quality of Service (QoS) is another option, which is typically integrated into most routers these days and makes it stupid easy (in theory) to throttle multiple systems without installing software on them individually, however I've never had much luck with it. QoS is intended to enforce bandwidth throttling by implementing priority rules such as by application/protocol, by client, etc. Unfortunately, most home and small office routers don't allow very advanced editing of the QOS rules since this is a feature mostly used by larger networks with more advanced routers. If you're looking to implement throttling on multiple machines, consider QoS first.
I've taken the liberty of gathering a few popular programs that you could use to throttle the clients connection. Keep in mind this method is not fool proof. Sophisticated users can and most likely will kill the process responsible for local traffic throttling.
Sorry for the lack of hyperlinks, I haven't yet been able to figure out how to properly embed links.

Thanks I will look at your links and see If I can try those out since I don't even know if Belkin is supported and resetting it to factory settings is too much of a hassle
•Install DD-WRT on your router and make sure that you have QoS options
