Tomato on WRT54GL and restricting bandwidth

[Viral]

I have the above router with Tomato and I have noticed that since getting it my internet just seems to be a lot slower. Is there any way of speeding things up in the settings? I connect via 2 homeplugs which have always worked fine, but just to double check I also used wifi and it was still slow. I have 2 tenants that use my internet connection both on wifi. Is there anyway to limit their monthly bandwidth?

Is it just slower for you? As they maybe using torrents or similar, which could be caning the upload, making it dog slow for everyone.

Its not my tenants as one is not even online right now and the other is not using a lot of bandwidth. I better call my ISP.
