When backing up to Airdisk, internet for all computers slows to a crawl!

[coledog]

Here is a description of my network for as much detail as possible:
DSL modem is hardwired to one Airport Extreme G version;
AEBS-1 is WDS linked to AEBS-2 at the other end of the house;
Hardwired to AEBS-2 is my AEBS N version for my MBP's own network;
USB drive is connected to the N router;
All the other computers (2 Gateway laptops, 3 PC desktops) all run G and I wanted the N speed for backing up Time Machine to my Airdisk.

I have TWO NETWORKS set up, the N hardwired off the G.

The problem is that when I backup the internet for all computers slows to a crawl.
It's obviously not the internet itself because as soon as the backup is done the speed returns. When we type in the IP address of the modem it takes forever to load so it's obviously the network slowing.

Why is the backup affecting ALL (both networks) computers' network speed?

If anyone has a solution to have 2 networks and still be able to print to ONE printer from both, please help!

Provided you really do have two networks (they have different SIDs), then a wild guess? Both networks are using the same frequency and are interfering with each other because you stuck with the default configuration setting? You want to have the two at least 3 to 5 channels apart as I recall.

Good thought, but one is channel 11 and the other is 6.

I am interesting in doing something similar...

are other people having similar issues? when timemachine is backing up to AirDisk, does network connections slow down for other Macs on the same network?

Coledog-please let us know if you were able to resolve your issue.

Hey all,
I figured it out! When I set up the N Airport I selected the N only 2.4 ghz.
I should have selected the N 5.0ghz option to keep it from interferring with the G network.

If there are any more details needed let me know!

Good to know, thanks man! Im about to set this up myself and this will probably help.

Here's a flowchart of how I did my network with all computers and accessories.

Hope it helps!
