Wireless networking is a sadly complicated thing. There are many things that can negatively influence wireless connectivity that are all invisible and can be difficult to track down.
Case in point, I recently started having problems with my wireless network, which had been working great for well over a year. The signal strength was great, the noise was low, but it would routinely drop down to 1mbps and for all practical purposes it was not even functional. After some research I figured out that one of my neighbors had started up a new wireless network that was within the same channel space as mine. (Quick primer: wireless channels in the US are 1-11, but they are not distinct... they overlap. The only channels that do not overlap at all are 1, 6, and 11). Another wireless network within the same 5 channels as yours can cause massive interference and congestion as a result that will bring your wireless network to its knees.
So, I changed my channel... and now my wireless network "fights" with a different neighbor's. They appear to be using it less frequently, so it's a better situation for me, but still crappy.
That's just one problem... you also can have actual noise generated by appliances. This can be really frustrating because it can be extremely difficult to track down what is causing the problem. And even if you resolve all of the problems in your own home, some neighbor can start up a network at any time and completely kill yours, if they are broadcasting with a strong enough signal.
All in all, wireless networking is a crapshoot. If there's any way to avoid it (going wired, using power over ethernet if your house's wiring is good enough), it will give you a far more consistent and dependable experience than wireless networking does.
