Is any one else experiencing issues? my speed is around 500mbps / 100 mbps
If you use the search function you'll find plenty.
Probably not what you want to hear but if you purchase a "quality" router that can handle the 910 / 110 package you won't have anymore problems.
It seems the supplied HH2 is not up to the job in most cases.
As quoted plenty to read about if you search the forums.
