Hi all,
quick latency question regarding Wifi vs ethernet cable.

Long story short, i had to move my computers to a different room since i'll have a second baby to fit somewhere soon.
The room that now has the computer has no phone/dsl plug nearby and since my modem also does wifi i've bought a couple DLINK Nano (N) keys to access the net from there.
Everything works fine, when i check Speedtest.net / pingtest.net i get the same results than before, when i was using a ethernet cable (ping/dnload/upload).
Trouble is, in WoW my latency has gone through the roof. Instead of the (crappy but manageable) 300ms i used to get (Australian pings are lame), i now get 800ms+ :-(
Also noticed that skype video was worse than usual.
The modem sits in a room not far away. I tried pulling a 10m ethernet cable to one of my machines and the latency magically went back to the expected 300ms.

Is this just a problem inherent to the wifi technology?
Are there any ways to boost the latency when using a wireless connection?

From what i've gathered around the net i have to check (later, as i'm at work atm):
- the channel, change it from the default "6" to something else (1, or 11 for example, depending on what other nets are around)
- the encryption. currently using WEP that is apparently slow, need to change to WPA/WPA2
- check with my ISP for a setting that boosts ping rather than dnload speed.

Any suggestions welcome, i'd hate to have a permanent ethernet link across the place >.<

Thanks,
Zub
