[SOLVED] Sudden Terrible Internet

[FirePots]

For the past few months or so, the internet has seem to dropped by a lot after getting my new PC. It's a weird situation. We are supposed to have gigabyte internet, and as expected only got about 200-300 mbps. This works on my phone, my macbook pro, and everyone else's devices.

After I got my PC, the internet has slowed to about 10 mbps to 15 mbps, as well as the upload speed dropped dramatically. I'm using speedtest.net for this. Everyone else's internet in the house has also seemed to drop, except small devices such as phones. Phones are still getting around 200-300, but everyone's desktops/laptops are getting terrible internet.

Can anyone help or clarify on what I can do to fix this? EDIT: On top of this, using an Ethernet only brings me up to 50 mbps. There isn't anything restricting my internet, things such as setting the internet to Full Duplex 1gbps.

Swap out the new PC's ethernet cable with a known working Cat 5e ethernet cable.

On your new PC are you certain that only one network adapter is enabled? Either wired or wireless - not both at the same time.

Check the IP addresses - especially if your network uses any static IP addresses. There could be a duplicate IP address.

How is your network set up? Did you add any network devices in order to connect the new PC?

Already have tried with a new cat 5e ethernet, with simular results, i disabled every network adaptor, but may have done it wrong. If possible, please clarify where this may be done. I dont know how to check for duplicate ip addresses and i did not add any other network devices.

Make and model of modem and router or modem/router if combined.

Who has full admin rights to the router?

On your PC go to the Command prompt and run "ipconfig /all" (without quotes). Post the results.

Did you set up the DNS Servers to be 1.1.1.1 and 1.0.0.1 (Cloudflare)?

And it appears that you deleted out the private network addresses used by your network.

Those are actually what need to be looked at along with the make and model router.

It does appear that only one network adapter is enabled (wireless Intel AC 3168)

And it is getting a "lease" somewhere but that "where" is not being shown.

Do feel free to search for other similar links to help you get comfortable with the concept.

Generally the troubleshooting in progress is to ensure that there are no duplicate IP addresses within your network, perhaps two routers trying to assign DHCP IP addresses, or two network adapters being enabled on one computer.

i also full resetted my interenet, and i set the dns servers to 1.1.1.1 and 1.0.0.1

Router is 172.16.0.1 and is currently providing the DHCP IP address of 172.16.0.4 to your new PC (Desktop RTS001K) via wireless.

However, the following information is still necessary:

"Make and model of modem and router or modem/router if combined.

Who has full admin rights to the router?"

Network connectivity generally is as follows:

ISP ---> Modem ---Ethernet cable --->[WAN] Router[LAN] --- Ethernet cable ---> Wired devices and ~~~ wireless~~~> Wireless devices.

The modem and router could be combined into one device.

If modem and router (or modem/router combo) are not correctly configured then the network will have problems as your are experiencing.

The make and model information is necessary to help troubleshoot.

And, just as a bit of backtracking, shutdown the new PC completely. Does the network return to the previous and expected speeds?

I'm not sure where to find who has full admin rights, the make and model of both router and modem, and shutting down my pc to find internet is hard as like I said my phone is consistantly getting high speeds.

Overall, that is necessary information.

"ipconfig /all" indicates a wireless connection.

Yet your posts mention connecting the PC with a new Ethernet cable. So what did you plug that cable from your PC into?

Device (modem, router, combo) information is relevant.

It was from a Netgear powerline. (2 pots, 2000 mbps)

 

[Ralston18]

Powerline adapters and the accompanying network performance are quite dependent on the quality of the supporting electrical circuit.

And what about the "other end"? There should be corresponding adapter there with an ethernet cable connecting the powerline adapter to the router. What testing did you do there?

Setup and testing:

https://www.netgear.com/support/product/PLP2000.aspx

https://www.netgearr.support/powerline-network-setup/

Also is it at all possible to temporarily run a longer ethernet cable from the router directly to your PC? Doing so would be one means of narrowing down the source cause of "terrible" internet.

I'm not sure I understand. May you please clarify?

ISP/network connectivity normally appears as shown in the following line diagram.

ISP ---coax /DSL/fiber cable---> Modem ---Ethernet cable --->[WAN]Router [LAN] ---Ethernet cable ---> wired devices plus ~~~~~ wireless ~~~> wireless devices.

[WAN] and [LAN] being Ethernet ports on the router (usually four LAN).

However the modem and router can be combined into a single device that serves both functions.

And all device (wired and wireless) must be correctly configured to be part of the network and perform according to the supported specifications. That configuration work is usually done by someone with administrative rights to the router. Who is that person in your residence?

That is why asking for make and model information is important. It can help understand the overall network hardware configuration and discover some misconfiguration issues. "ipconfig /all" helps in much the same way.

For powerline adapters one of the Router's [LAN] ports would be used to connect to the powerline adapter and the electrical circuits are used to carry networking communications to a second powerline adapter service another wired device (PC, printer, NAS, Access point, switches).

Another line diagram:

Router [LAN]--Ethernet cable --> Powerline adapter # 1====electrical circuit ====> Powerline adapter #2 ---Ethernet cable ---> Wired device.

There is a dependency on the quality of the electrical circuit being used and if the powerline adapters are on different circuits the connectivity/lkperformance is probably going to be very poor. Plus powerline adapters need to be paired..

So where in your residence is that second powerline adapter and what is that adapter plugged into?

Feel free to copy and edit the above line diagrams to show the connections being used in your residence.



Show all devices ("everyone else's) and include make and model information for modem, routers, switches, powerline adapters.
