I am not 100% sure what you are referring to, WAN or wifi speeds with your vague statement about your speeds.
With the guide, hopefully you can get back to where you were before.
You may want to write down or take screen shots of your configuration so the next time your not scrambling to figure out how you had it set the last time. _________________ Router currently owned:

Sorry about the vagueness. I read the info on that link but I remembered there was a more detailed one. Anyways, I was talking about just wifi speeds.
I checked the channels and made sure it wasn't occupied. The other settings I went off that kong's link. I attached a screenshot with the current settings I have. Any thing you see might help?
