how to debug epicly slow wifi but fast lan

How can I debug a problem where my wifi is REALLY slow(it takes a minute for this page to load...even my router's admin page - 192.168.0.1)?

I've tried upgrading my hardware firmware(using a DIR-600 Dlink router). And it still sometimes happens. LAN connection is decent, but using WIFI is really deadly. And I don't think it is signal because I have 100% as I am beside my router.

What gives? What's wrong with my wifi? Is this hardware? software? where do i satrt debugging(short of using a new router)

here are some benchmarks i made using a simple ping to google.com:

You can see the HUGE difference

Solution 1:

First thing is to try different settings on your wireless.

• Try a different channel - you may be getting interference from another source nearby.

• Try different encryption settings.

• Try moving your router to a different location.
