Anyone joining my server recently will have discovered massive lag spikes.
After checking all the computers in my house, I discovered that no one was DLing anything (Although my sister has limewire and was sharing her entire music collection :/(But no one was DLing, I'll talk to her tomorrow)). However, the last thing I thought was the unsecured Wireless N Network. Well, that's changed now. Lets see if this changes anything.

(There were three people connected to my network before. two through wifi B, one through G. Who uses B anymore?)
