connections between modem and switch affecting rest of network?

post #1 of 7
Thread Starter 
Hey, everyone. Longtime reader- thanks for all the info you've already helped with.

I have a 2-part question that I was hoping someone can help with. Been searching all over the forum and can't find an answer.

Basically, I have a DSL modem that doubles as my household wireless router. I have a Trendnet Gigabit Switch, a Seagate 220 NAS (RAID 0 for performance), and an iMac (3.06 Core 2 Duo). I had a lot of files on it that took up 900GB so I went with a NAS to free up space.

My UVerse cable boxes (2x) are hooked up to the modem/router along with 4 wireless devices. I got one Cat5e running from that to the switch. I have my NAS, XBox 360 (DLNA to stream from NAS), and iMac running off the switch.

1- Is it true that if one wired device on your network isn't Gigabit, nothing runs at Gigabit? Worried about my Xbox 360.

2- What about cat5 vs cat5e? I have cat5 running between the UVerse boxes and the modem/router. Not sure if that's jeopardizing my connection between NAS and iMac. I'm hoping it's not a problem because it's not between the NAS and the iMac and switch.

Any info would help. Google yields a lot of conflicting facts.

1) No
2) Cat5 generally designed for 100 mbit.
Cat5e can handle 1 gbit.

Cool, thanks, Beers.

Basically, my set up now is A-OK and don't worry about anything? (Everything coming out of the modem/router is cat5, everything touching the switch is cat5e.)

Those old-school cat5 cables and devices aren't bugging what's connected to the switch?

CAT-5 components may function to some degree in a gigabit Ethernet, they perform below standard during high-data transfer scenarios.
What switch are you using? 100Mbps switch?
Remember your network throughput will only be as fast as the slowest part

See, that was my original concern. Even if I upgraded all my cables to cat6, am I still slowed down by devices that aren't gigabit (blu-ray player, Xbox).

And yup! Using .

This is not true if you have a gig switch and two gig devices the switch will pass data between them at full gig speed.

Sweet, so you can have 10x the bandwidth until you actually need to transfer data ?

That's a pretty short sighted (not to mention, false) generalization..
