cat 5e vs. cat 6 cable

We have cable internet speed of 200 mbps / 20 mbps (we may upgrade later this year to 300 mbps). Our office has cat 6 cabling. We are moving to an office that has cat 5e cabling.  Will the internet speed slow down when we switch from cat 6 to cat 5e?

Unless the wiring was done improperly you will be fine.  As everybody has stated, 5e is good to 1Gbps and your Internet connection is only 200/20 Mbps.  

Assuming everything else in your network can handle 1 Gbps, your LAN speed is 5 times that of your down steam Internet speed.  If anything in the path between your users/servers and the Internet connection is only 100 Mbps, then you will not get the full 200 Mbps down load speed.

No. Cat5e is good to 1 Gbit/sec. It depends on switches and general network setup, but I have not see Internet speeds outrun Cat5e setups.

Cat6 is an improvement on Cat5e, that is true... Cat6 is better resistant to external disturbances and it has a better bandwidth of 200Mhz vs 100Mhz for Cat5e, this means it allows speeds up to 10Gb, if it's certified for it that is.

Now, will you see any difference between it, that is a good question, the best I can answer this is with "it depends", are you a company that does a lot of streaming to the endpoints? Some heavy broadband using apps? Maybe you might notice a slight difference. If you are just doing some basic office type stuff you won't have much to be afraid of.

If your 1Gb connections aren't saturated now, you won't notice a difference in day to day use.

What John said, i have 325mbps running on cat 5, you're good to 1ghz if you see yourself doing 10 in the future then do what spravtek said

Cat6 is good cable and I do mean it shouldn't be used, just that there is no need to change it just for somewhat faster internet.
