Hub Problems

[#1]

hey,

having a problem with the hub with throughput. seems to limit me to 25mbps. I've been trying to diagnose it and the only thing i can think of is that an iphone is connecting at say 6mbps (was in the dhcp logs) then its bringing my whole network to a halt. then it doesnt seem to return to normal (even though the iphone in question has left the network). my laptop is syncing at 433 mbps but 25mbps throughput???? if  i reset the router things return to normal until a low sync then it happens again. obviously i cant keep resetting the router or DLM may get involved. any advice or tips would be great

Perhaps same issue as reported by another user?

(5 GHz wireless SSID also renamed with no apparent improvement)

yeah, I've decided to give up on this hub and buy a vr600 or 900.
