Wi-Fi Lag?

[Death Eye]

Is anyone else prone to having crippling lag in SSBB on Wi-Fi?
The one time I tried a battle online the lag made it impossible to do anything.
I'm not sure if the problem is the router placement or the fact that Alberenza is (apparently) in the UK and I'm in the northeastern US. Or if something else was taking up the bandwidth.
The reason I think the router placement may have been the problem is that it's in a different room with a wall between the Wii and the router and it's next to the computer (which is sitting on a metal table. Or at least I think it's metal.). Does that sound like something that could cause a problem?

I tbink we all think it's just your wi-fi.

I've never experiened lag before.

my router's ion a differnt floor, so it's not that.

Well, if a floor doesn't cause a problem, then a wall wouldn't.
My brother was probably downloading something at the time.
I should see if my Wi-Fi works decently when he isn't.
...How would I go about running a speed test of some sort on my Wii?
