I have Verizon 100k DSL, and at my computer I can generally get download speeds of 70-80 kb/s, but beginning suddenly a few days ago, I've been getting speeds of +/-10 kb/s.

Some Facts:
  • It's been over 100°F in the past few days.
  • Using USB wireless produces the same results as going with the LAN cable.
  • This computer seems to be the only one experiencing trouble.
  • The desktop is quite a distance from the router and modem set up (probably 20-30 yards through walls and a floor), but that's never mattered before.
  • Sometimes, but not every time, when I log in to my computer, I get split-second messages that a network cable is unplugged.

Things I've Done:
  • Reset the router and modem.
  • Made sure all accessible LAN cables are plugged in correctly.
  • Reinstalled ethernet drivers.
  • Sprayed dust out of my chassis.

I have no idea what's going on.
