Changing from Cat5e to Cat7 Ethernet Cable at home?

Hi,

Anyone offer up some advice on upgrading from Cat5e Ethernet cables to Cat7?

Upgrading the Home Network to increase performance on the Homeplugs and entire wired network at home.

Are there any disadvantages of using Cat7 (aside from the cost obviously)? Would I be better of sticking with Cat6 or Cat6a instead?

Unless you are upgrading your switch and network cards to 10gigbit or 100gigabit ones it will not make any difference from Cat5e. Cat5e can handle gigabit already, Cat6 might improve things a bit.

You have not said why you need the cable upgrade.

It seems very extreme for a very small performance increase. What makes you feel upgrading your wiring is worth the trouble?

You don't need to upgrade the cables, just replace those Homeplugs with Cat5e cables and make sure that all relevant devices/network switches support Gigabit.

Homeplugs are a convenient stop gap measure for when running cables is not practical or would cause the other half to divorce you. They are however sluggish, temperamental and can cause interference with other devices connected to the same ring main.

Unless your cables are the cheapest most awful cables in existence then you won't notice a difference until you get into the 10's of gigabits and even then you might not see it.

Also unless you're sat there copy and pasting as many files as you can as fast as possible then you'd never see an improvement.

Thanks for the quick replies. I'm also using CCTV connected cams using POE via Cat5 cable which I feel is the bottleneck with 24/7 streaming and recording of feeds. The feed is dropping out every 10 seconds while viewing it on a mobile phone app.

I've checked the homeplug speeds as is (using the tp-link utility) and getting around 125mbps. Looking to get some better homeplugs soon, but I want to ensure the wiring isn't an issue.

@Summoner The reason for the homeplugs is to cut down on the cabling around the house and I find the homeplug bandwidth more stable than using WiFi for the Cams

So, you are having issues with your DVR recording all the cameras and you browsing the web/downloading stuff at the same time?

It won't be your cat5. The app is probably connecting to a website. Then back to your dvr

Nothing gets close to even using cat5e specs yet, will be years before it does, name something that needs gigabit ?

You're missing the point. The real benefit of Cat6 is not speed but bandwidth and resilience from interference. The majority of people don't remember this. There are many applications where one usurps the other.

Ditch the homeplugs before changing your cabling from Cat5e to 6 or 7....that will make a far bigger difference

That was exactly what I was gonna start with. I've started by ordering flat Cat7 cable to do a direct run to a router with gig ports.

Do your homeplugs run full or half duplex? Many of the older sets only run half....if they are half theres your bottleneck right there....

btw..running Ethernet cable externally is always another option. Much of my Cabled network pops in and out the house when it gets to awkward to hide places :-)

and despite what many 'experts' will tell you it's fine to run standard Cat5e+ externally as well. Don't waste money on expensive external cable
