Quality of wifi? 

I'm currently visiting france and have stayed in two apartments with v.5 boxes.  In both cases it seems the wifi router can only cope with one device at a time.  Any info available on issues with DHCP server? I don't see any mention of this problem on the french version of the page either, but since I see it on two different v.5 boxes I feel like it may be due to the hardware...  comments anyone? 88.176.26.42
