sgoshe, ya beat me again .. and in fewer words too !
I owe you 100,000 Gen4$.
Its rather long winded and covers a lot of ground but you may wish to read John's thread on his multiple Apple router setup on the Shack:
There is also this Apple related topic:
The thought is .. is .. could an address conflict causing "dropouts" be seen a "slow" as new DHCP leases are made after a momentary "recovery" ?
While the latest modem firmware update has been "repealed" for the moment it did not have the "Alt Router" function available.
While this alternate timing function is only used by a few, it is important to those few.
Please point that out to the team that is presently working on the HT1000/1100 firmware updates
