My old DSL router died a few weeks ago. I wanted to buy a replacement but Holland had done that about 5 minutes before me. Shops were all out, so I ordered a Speedtouch 585 from a webshop. Got it a bit late :(, but worse, it also turned to out to be broke. So I sent it back, got a new one and set it up yesterday. Tonight, I switched on WiFi with WPA security. Now I just need to find a good place to put it, because I was sitting 3m from the damn base station and my connection dropped away every 5 minutes... Grrr
You *must* really use WPA, BTW, WEP encryption can be cracked in under 10 minutes these days. So if you have personal stuff on the network, use WPA. If not, don't bother with security at all! Let it roam!
