When the error rate goes up, the routers will negotiate a smaller
maximum packet size, which has a better probability of arriving
intact. However, such changes are usually much larger than what
you're seeing. I've seen routers negotiate MTU's down to about 512
bytes. However, I've never seen it change in such small incriments as
what you're getting. Aliens again.

You're on Malta? Cool. The problem might be explained by congestion
to whatever backhaul is being used to the continent. However, it
would not explain why it's fast with ethernet and slow with wireless.
I'm still mystified.

Some routers (i.e. Linksys) require that the reset button be held down
for about 30 seconds or the reset to defaults fails. It's often
better to do the reset to defaults from the web interface than the
reset button. I guess your MSI RG60G night need a similar long reset
time.

Well, by this time, I suspect you've changed literally everything with
a minimal hope of putting the settings back to the correct defaults. I
guess you did the right thing by resetting everything and evicting the
aliens.
