Hello,
I have a wired gigabit network that is organized Modem=>Router=>Switch (x4)=>clients in my own residence. Went to update the firmware on the X-Box for the first time and all the clients were dropped. The switches are necessary due to a single run CAT5 to locations serving multiple appliances, e.g. receiver, DVD and X-Box in the home theater, 2 kids computers in study, etc.

Not an expert by any stretch but I know my way around these issues a bit and I'm baffled. Reconnect it all in sequence (as above) and the whole network is running but slow and wildly varying speeds, 1-5mbps download rather than a consistent 30. The router is maybe 6 years old. Could it simply be overloaded somehow? I can get full bandwidth plugging directly into the router with everything else offline (save modem), but if I add back the switches, that directly connected computer will see the bandwidth drop.

Ideas for me? Hesitant to dump router because it's a pricey Apple Time Capsule that backs-up everything. Thanks!

You have the 4 switches each one plugged into the router directly or you have these dasiy chained together somehow. You must be very careful that there is only a single path between any 2 switches.

Try FING on android or itunes. Check for any duplicate IP addresses.

Start with all wired items powered off and check FING and the "My Network" type display on the router. Anything shown?

It is possible one of your cables got mangled and is causing the errors. Disconnect one switch at a time.

All switches directly to router.

Will do this this evening. Thanks!

Fing is a neat app!

Found it- Airport Express that was erroneously plugged into switch under daughter's desk after surge protector failed recently (did it's job!). Just coincidence that I was trying to update Xbox firmware.

There was an extra patch cord hanging out of the switch so she logically plugged it into Airport that was not plugged into anything, actually operating as wireless network extender for handheld devices. Disappointed that the Apple Airport Utility did not show Airport as connected both to wireless and wired. Exposing such configuration mistakes would seemingly be at the core of it's purpose.

Thanks guys!
