If you own a D-Link Router, reset your Wifi Channel

I've had a DGL-4300 Wifi router for the last 2 years. After moving into an apartment complex in SOMA, my Wifi became mindnumbingly unreliable: I barely ever got an IP address. Even if that succeeded, the connection would be so slow as to be unusable. Plugging in my network cable would work perfectly, though.

Last night I had an epiphany. I checked my router settings, and it seems like D-Link routers are preconfigured to use "Super-G with Dynamic Turbo" which in turn forces the router to Wifi channel 6.

My apartment complex is so heavily populated with techie types, and all of them have Wifi. A large percentage of Wifi routers is made by D-Link. Yeah, all of the D-Link routers in my neighborhood were probably fighting each other for airtime on Channel 6.

I logged into my router's admin console (usually at http://192.168.0.1) and chose a different channel [1]. My Wifi has been speeding along ever since.

Notes:
[1] Humans are bad at randomly selecting Wifi channels. Open up python on your console and type:
>>> import random; random.sample([1,2,3,4,5,7,8,9,10,11],1)
