Good info, John. Here is a somewhat related observation when I was playing around with two wifi routers recently.

I was testing a new router. I was trying not to interfere with the older router which was in use, by setting a different SSID and a separate channel. New router channel 10. Old router channel 11. While my PC seemed to connect to the new router's wifi network normally, it was not stable and dropped out from the internet constantly. I messed with most of the settings I could think of in the PC and in the router, to no avail. Finally, I changed the channel of the new router from 10 down to 8. You know what, it worked. The network was finally stable! So my conclusion was the channels were too closed, causing a significant interference, which rendered the network connection unstable. By changing the channels to be further apart, solved the interference problem.

So yes, interference no doubt can decrease network throughput, or even blocks the network completely.

I had serious speed issues with my wifi and found a program that shows me all the wifi connections near me and what channel they're on.

I am in an apartment building and am in range of at least 12 wifi hotspots at all times. I checked the channels others were on and chose one nobody was on.

Helped significantly.

I also set up MAC Filtering which seemed to help, but not as much.

Just wait for 1080p HDMI WIFI to get released on a grand scale. Think about it, no more wires and no loss in PQ/ AQ. Talk about massive interference.

12 wifi connections! That's quite a lot. 5 or 6 were the most I found in the neighborhoods I live and used to live. All blames to the wireless revolution, everybody sticks in a wireless router in their home, regardless if they know what they're doing or not. Glad you find an available channel in this mess.

Mac filtering is good, keep out the intruders and keep the bandwidth to yourself. You should also disable WPS (Wifi Protected Setup), if you have that on your router. WPS could be a security vulnerability to your router. Hardly any one use that feature any way, so disable it for good.

To John's reply. I noticed many consumer level routers are set at channel 1, 6, or 11 by factory default. I guess it's suppose to avoid channel overlapping. But if you do a wireless scan like DoubleDouble did, you will find that these channels are over populating (especially 6 and 11), and hardly anyone uses the channels in between. That's because not everyone knows about these channels, most people care only if they can surf the net. It could be a problem in heavy wifi usage areas.

You're welcome John. That's what this forum is for, to share and learn more about technology from each others. Unfortunately, there are lesser and lesser members here remaining to share and learn...
