slow upload speed on 1 computer only.

[joeykruithof]

recently i have upgraded my internet with a 4g router, because a normal connection is too slow. now my download speed is great on all devices, and upload is great on all of them except my own PC. a speedtest on my phone over wifi shows 100mbps download, and 40 mpbs upload. now on my pc, download is also around 100mbps, but upload is around 3-4 mbps. it is connected via a cat5e lan cable, in between is a switch, which i have replaced, same goes for all the cables in between my pc and the router. when connecting a wifi dongle and testing my speed, the results are the same, slow upload speed. so im guessing it is a problem with my pc, maybe windows 10? i've googled for quite a bit and couldnt find a solution that worked.

thanks in advance!

Not sure that I understand the connectivity involved.

On the problem PC do you have both the wired and wireless network adapters enabled?

If so, disable the adapter you do not wish to use. Only one network adapter should be enabled.

Are you able to test your PC's download and upload speeds without having the switch in the connection path?

Sorry, should have explained a bit better. I only use 1 adapter at a time, but the result didnt change much. I have removed the switch and tested it with a direct connection to our router, and the result is still the same.

Using only one adapter at a time is correct. Barring the need to do bridging.

However just "not using" the other adapter is not enough. The adapter must be disabled - be sure that you have disabled the adapter.

What is the make and model of the router? Do you have the User Guide/Manual?

Ensure that you are using a LAN port on the router. Some routers have ports that can be configured as WAN or LAN.

The wifi adapter is a usb one, and i always unplug it when not using it. The router has seperate ports for LAN and WAN, im sure im using LAN. The router is made by ZTE, its called an experiabox v10, exact model i dont know, currently not at home. It. Has manual, but there is not really anything of interest in it.

Does the following link match your ZTE?

https://uk.hardware.info/product/280129/zte-kpn-experia-box-v10/specifications

Are you using DSL service via your ISP?

If only your computer is affected then, overall, the explanation is likely to be a configuration problem with respect to your computer. And that problem may be being causing by switching back and forth between wired and wireless as you have stated doing. What circumstances require the switching?

Are you able to run "ipconfig /all" (without quotes) via the command prompt on the problem computer and post the results?

yes that is my router, but we do have a 4g "router" in our network, that provides most of our internet, because our DSL connection is insanely slow. I dont switch back and forth all the time from LAN and Wifi, 99% off the time i only use LAN, but i had the wifi dongle to test if the speed was the same regardless of LAN or wifi.

Okay - two routers.

How are they connected - one should be the main router (providing DHCP IP addresses) and the other router basically just a switch with DHCP IP addressing disabled. Connecting Ethernet cable being Cat5e and going from LAN to LAN between the routers.

I.e. (as I understand the connectivity):

DSL ----> Main router [LAN] -----> [LAN] Your ZTE router [LAN] -----> [LAN adapter] Your computer

Your computer is obtaining its' DCHP IP address (now at 192.168.2.14) from router 192.168.2.254 (all subnet masks being 255.255.255.0)

Look at the other router's IP address. Only one router should be providing DHCP IP addresses and that should be the router that your computer looks to for a DCHP IP address.

As for DSL being slow: Check the splitter (also known as a filter). They can be quite problematic. Otherwise there just may be a bad connection along the incoming path from your ISP.

The other router isn't really a router, although im not sure what to call it, its a sagecom and was delivered by my ISP. Its not providing DHCP IP addresses as far as i know, and it isn't really configurable, just some stats etc on its admin page. our main router is the ZTE router, my connectivity is like this:

DSL --> ZTE router --> 4G router, the sagecom thing --> switch (which can be removed) --> my computer.

the DSL being slow is a known problem, which is why we got the 4G router, because with DSl we could only get a max 0f 8 mbps download and 0.5 upload. My sister's laptop, which is connected with the same switch, gets normal upload speed, about 30-40 mbps.

Key point:

A network will only be as fast as the slowest device.

So if the DSL is less than what you are paying for, it may an ISP problem.

Otherwise, we need to determine what the "sagecom thing" is and how it may be configured.

May be double NATTING, may be some IP address conflict, or some error of omission or commission with respect to the devices involved.

Please take close look at "sagecom thing". Some model or version number. Any documents that your ISP may have provided with it.

If, as you state, your sister's laptop gets normal upload speed, then the issue is even more likely a configuration error on the slow computer.

Some devices just do not play well together and we need to determine if that is indeed the situation for you.

Its called a fast 4360 air kpn sagecom 50001, kpn being my isp, and the only manual was a Quick install manual. DSL line is slow because of our location, the line coming can only give us max 8 mbps down and 1 up, which is why we got the sagecom, which provides us internet by 4G.

Something such as this "Sagecom":

Not finding 4360....

Maybe:

If you are still dependent on DSL for service that is the limiting factor.

With the laptop being faster then you that your network is capable of the speeds you have noted. If only the one (your) computer is falling short then most likely there is a configuration issue.

You can test that by plugging her laptop into the connection your computer normally uses. Determine if the laptop continues to get the higher speeds.

Then compare the LAN adapter settings/configuration between her laptop and your computer. Match your computer's LAN adapter configuration to the laptop.

Change only one thing at a time and keep notes in case you need to undo something.

Try manual settings if "auto". Or if "manual" now, try auto. Check speed and duplex.
