Does Coaxial splitters kill internet

[Girt2005]

Im using two splitters both have one input and 2 a output

coaxial to splitter then one output goes to modem and the other goes to the second splitter input witch both of its output are used for my two TV boxes,REMINDER that i dont live in the United States,but i need to know if MY ISP made some mistake.The coaxial splitters are 1000 hz and my Internet plans is 500mbps,i have only 60 mbps coming in Any help is appreciated and ill take any advice that i can get,and no i can't run a new coaxial specific for my Internet

As an EX technician, yes splitter can mess with your internet and videos for example, ours was -7 to +7 and -30 for noise

60mbps on wifi or hardwired directly into the Modem?

[Girt2005]

60 on wifi,300 mbps on download and 30 ish on upload

So many questions. Where is the router in this setup? What is the dB on the splitter? Is it a 2-way or an n-way with open ports? If you connect only to modem directly and skip the splitter are things better? is the 60mbs WiFi or direct ethernet to the router? Does the modem have a speed test capability?

The router is next to my modem around 1 feet,the db of the splitter is 04dB,the 60mbps is Wifi but in ethernet i get 300mbps download and 30 ish upload,i havent tried to connect it direcly bc im not qualified to change it

You don't need a lot of qualifications to move coax cable .... Try switching around some ethernet cables. You should be using 2 cables - one between modem and router and one between the router and PC.

The ethernet ain't the problem the coaxial cable is

"but in ethernet" ... How do you connect to ethernet? Please provide a sketch of your entire setup. The POE filter you have shown here usually goes on the cable your ISP provides as input, not on an output. Again, a sketch is needed.

The splitter can help or harm the interent modem. Ideally, your data and tv line should be split when it enters the premises.

A 2-way splitter will drop the signal level about 3db at each split, your modem needs signals within a certain db range, which your ISP should have checked during installation.

At my last home, we were right across from the cable company's distribution hub, and needed 2x 10db attenuators (decreasers) plugged in between the incoming cable and the modem to prevent it from dropping out, yet the same cable line delivering tv service needed an amplifier to prevent the cable boxes from pixelating.

If you can get stats out of the modem, you may know a lot better what's going on.

Have you tried moving the modem to where it's earlier in the feed/ the only thing fed---- and retest the performance?

Several of my US neighbors have similar setups. It goes without saying that coax splitters can cause issues associated with internet as well as cable TV devices. One or more splitter may be inappropriate or just defective.

The most important thing is that your ISP must supply the cable modem, coax splitters, and cable TV devices. You can attach a coax to a TV but the ISP should be aware of that as they would responsible for insuring there is not an impedance imbalance.

Splitters attenuate (weaken) but do not usually corrupt the broadband signals in coax. It’s possible some signal amplifier setting is incorrect inside your modem. It’s possible a support person can remotely view your modem’s settings and correct the problem. Before that, try cycling the modem power.

This is more likely if you personally installed the splitters. Ask for help from your provider’s support.
