Ugh. I think there is trouble on my side. My wi-fi is usually very stable, but recently it even went as far as to disconnect during a battle involving myself and my opponent using my router. I'll see if there's anything I can do.
... Is there something wrong? Is this normal? I haven't traded over Wi-fi on any game more recent than Diamond/Pearl!
B/W wi-fi really hates us. XP I'm going to try asking for trade now.
