face: if the speed is good on a hardwired connection, it's not an ISP problem, no matter what other factors come into play. Christ himself can come to you in a vision and tell you that a port reset is necessary, but if the speed is fine when close to the router, let alone wired, then Christ is wrong.

lom: Got any metal or bookshelves between your router and where the notebook is when you have the problem? What a lot of people don't realize is that wifi = RF = electromagnetic radiation, and subject to the same rules. This means it will refract, diffract, and reflect the same way any other EM wave does. For this reason, keep the fricking metal out from between your router and computer. Solid sheets will reflect the RF. even mesh will generate a (weak) electric field when EMR hits it, and EM fields absorb EMR. That's why bluetooth headsets cut out when you pass through an aluminum exterior doorframe. Got the router in a cabinet? Take it out. Hardwood absorbs quite a bit of EMR. (pressboard and plywood not so much) If your router's in a metal cabinet, you've more or less enclosed it in a Faraday cage. Get it out. A lot of people dismiss bookshelves, but paper absorbs more EMR than bulletproof glass of the same thickness, and chances are, your RF waves are hitting the books on the spine and traveling through the thickest part. Lastly, don't forget that the most common form of EMR is light. Your wifi is made of photons. Once you learn to differentiate between reflection and phenomena like absorption, refraction, and diffraction, you can think of your wifi waves in the same terms as light and have a pretty good idea of what's in the way. Reflection is a bugger, though--the colour of materials don't make a lick of difference to RF because the frequency is much too low for the surface texture of most solid objects to reflect a significant amount--so while light won't go through walls, RF will. A handy way to think of it is to imagine a world where everything is transparent, but the same density. Can light get there? Then neither can RF. Would light be dim as hell by the time it got there? Then your wifi signal is going to suck.
