Need some computer network help
So I have a new router in the main part of my house. It has two ethernet ports and is wifi. I have 3 devices in the main part of the house that I wanted to wire. In addition I have an ethernet cable running from this main part of the house to the far side of the house because wifi sucks.

So would I use a hub or a unmonitored switch? I bought two small tp 5 port switches and it literally tanked my speed in the far side of the house connected by ethernet.

So it was 5g router/receiver in main room to switch, then used 4 ports. 3 ports for local devices and the 4th port for the ethernet to the back house. In back house ethernet connects into the switch and three devices plug into switch.

Did I do this wrong. Thanks!

Make sure the routers, switches, and cables are all rated for 1 gigabit speed.

CAT6 is just the cable type. You need to verify the speed of the router and switch.

Also, if it's old cable, check or redo the end connections.

A line tester is cheap and cables/connections don't last forever.

I've fixed many speed/connection issues by replacing perfectly "good" looking wire with new runs.

Honestly dude just figure it out. That’s how this type of stuff works. There are so many troubleshooting things you can do to figure this out. You just need to painstakingly do each one. You aren’t going to get anywhere looking for a quick fix on GLP you would be better off googling

Check without using that cable going all the way through your house, but a nice expensive shorter cable just to test

Re: Need some computer network help
are the switches actual gigabit 10/100/1000 capable?

log into the router
and check if it's really a gigabit 10/100/1000 capable device

CAT6 will only do what the router, switches, and NICs are capable of

you can run CAT6 on ancient 10mbps cards
and it works

CAT6 will not increase the speed of devices only capable of 10/100 to be capable of 10/100/1000
oh hai!

Internet speed?
All devices conected are 10/100/1000T capable?
The router or pc had enabled the gigabit speed?
You had a wifi extensor?

Using a pc conected to a rj45 port, test the speed connection between the devices(not internet)

Check the rj45 terminals in the cat6 cable

Re: Need some computer network help
Here is the info. The router GUI is shit... really nothing to change or check on speed. I connected a laptop directly to the router bypassing the switch and I got full speed. As soon as it hits the switch its crap. Used a dozen cables, new, old, etc. known reliability and nothing changed.

Router - FAST 5688W

Switch - TL-SG105(un)

Re: Need some computer network help
verify each port with 2 different cables. check speed.



then add the junction and see if the speed drops.

trouble shoot and process of elimination

Ive tried every port.. they say its plug and play? Only two ethernet ports in back of gateway, so it goes from one of those to the switch. Switch has 5 ports... TL SG105(un).

Ive tried from gateway to port 1, port 4, port 5.. ran the test and no change. Unless Im doing something wrong. Thanks!

I swapped out cables on the ports and reran speed test.. nothing. So basically from gateway to laptop... full speed.

From gateway to switch to laptop, changing out ports and cables did nothing.

Is the 5g even a proper router? Doesn’t sound like it....

Ditch the switch, get a proper standalone router and just use the 5g thing as a modem only.

Re: Need some computer network help
Was just looking at the specs on both pieces, looks like they're all gigabit copper. Should be capable of more than what your provider ?T-Mobile? is serving up.

I'd try plugging your laptop into the cable that you have run...the one that you're using to connect the switch to the router. Run the speed test from there, see what you get.

If that gets good speed, you know it's an issue with the switch. If not, probably a cable (or router) issue. Process of elimination.

yes, and if that does not change. sounds like the switch.

Only if you have eliminated any possible problem with any of your cables. and your laptop gets high speed directly from router.

then it must be the switch.

Just did a bit of googling.the switch port that you plug into from your modem shouldn't matter. Someone reported having the same issue as yourself. The fix was set everything up as you require then restart your modem. Try it...might just work
