We have also found that turning up the power on these babies helps them
alot - of course you still need to check for the usual culprits first:
- wireless phones in the house
- Neighbors stomping on your signal
- Cthulhu infested walls, etc
You don't need to load the latest firmware - or a rogue firmware to do
this. There is a published hack that lets you do it from the current
firware - see the TriLUG presentation from a few months back.
(running firmware 3.17 and loving it!)
