Question Unusual internet speed problem - - - is it hardware related ?

[RatsMund]

Why is my internet speed limited to 17.5 down / 2 up?

Win10, i7-9700k, 16G ram, Nvidia 2070-supra 8G, Asus Rog Max XI Hero (Wi-Fi) ver 1

I get 100+ down / 20 up Starlink and am duplexed with DSL line 40 down / 5 up with switch selecting best speeds.
PC maxes out at 17/2 regardless. Ethernet line checked and wireless checked. IT troubleshooter bypassed ethernet/wireless card via Gen C USB port and got 17/2. He advised most likely motherboard problem and to get a new PC.

Network adapters up to date on version and shows working properly. Played with speed setting (now at 1 Gz) - no difference.

I'm suspicious this isn't a true motherboard issue. A couple of crazy options, 1) ethernet card is dead and the system defaulted to the built in motherboard capability? 2) Some sort of BIOS or software default setting that got mysteriously changed.

All options welcomed.

What do you mean duplexed? There is no such thing in networking.

You also can not combine two internet service's bandwidth.

You can only use something like dual wan load balance / failover router.

Starlink wired connection to WAN1
DSL wired connection to WAN2
and wired connection from your pc to any lan port of tplink router.
Your wireless adapter will be useless here.

How do other devices on the same network perform?

By duplexed I intended to communicate that I have a switch that surveys the performance of both inputs (i.e., Starlink and DSL) and selects the highest performer for use. Sorry, I understand I used confusing language in the initial thread. I'm not technically sophisticated enough to understand the specific description but what you describe sounds like what I have. I understand that the WiFi connection has nothing to do with the load balance switch. I only offered the information on the WiFi performance to inform that it doesn't matter if the PC is getting ethernet input or WiFi input, the down/up speeds are the same in spite of the fact that both inputs are very much higher then the max speed being seen at the PC. Hope this clarifies.

All other devices on the same network are performing great. Cellphone is hitting high speeds and so is my wife's PC on WiFi. As I said, I've had both the WiFi and ethernet connections checked by an IT professional (a really experienced one) and he validated both the ethernet cable used for the PC and the WiFi inputs were running about 100 down / 20 up. Actually, often better then that. So, I know this isn't a network problem. This is a hardware, software configuration, firmware catagories problem. I've just never heard of a "compromised" ethernet/wifi card. My experience has been go/no go, not decreased with performance set at some max rates. Mine happens to be 17.5 down/ 2 up regardless of ethernet or wifi connection.

On the computer in question run "ipconfig /all" without quotes via the Command Prompt.

Copy and paste the full results into your next post.

Also include make and model information for modem, router, or modem/router if combined.

Perform a Network Reset first.

My system uses the newer "load balancing" tech. It will send packets through both connections simultaneously balancing load during times of poor overall service. At least that is what I've been told.

I had hoped to get this resolved prior to surgery but I didn't. thanks for your response but I need to put this aside for a few weeks.

You have to tell us what this duplex / load balancing is and how it's configured, No one can help without further info.

I saw your other comments about surgery so we will be here when you get back.

Try to run a simpler connection and get that working first. Do not run this load balance garbage.

So what you talk about is pretty much impossible. Longer explanation follows.

Even with very simple primary internet that switches to back up does not work well and has all kind of problems. The issue say you are logged into your bank on ISP 1. All your traffic is coming from the public IP they provided you. If ISP1 fails and you switch to ISP2 your public IP also changes. The bank is going to be suspect of any different IP and make you log back in. Your pretty much will lose every session that is active.

Trying to run both at the same time makes this issue even worse. Your IP address will now change at random times. You will constantly drop sessions.

So some fancy VPN providers claim to be able to bond 2 connection. What you do is form 2 vpn tunnels one over each ISP and then connect both tunnels to the same VPN provider. You are now using the VPN providers public IP pool. BUT you now have a new issue.

So lets say you have 2 connection and to make it simple to start with lets say they are the same speed. Now lets say you have a stream of packets going from your house to the server. The first packet is 1500 bytes and then you have 10 packets of 150 bytes. So it put the 1500 byte packet on connection 1 and send the other 10 packets on connection 2. Sounds fine right...but it is actually very bad. What happens is the receive machine receive packet 2-9 on connection 2 and before it receives packet 1. It assumes packet 1 was lost and requests a retransmission. If it gets what it thinks are too many lost packets it will drop the session. This is made much worse if the connections run at different speeds.

Now if you have big money there are actual load balancing servers you put on both ends of the connection. You would have to run this server as well as the 2 vpn connection yourself at a hosting site. These servers will chop the data up at the byte level and then reassemble the data at the far end so the packets do not get out of order.

.............. but again the short answer is you can not load balance 2 internet connecections.

As suggested by @bill001g , a lot of time load balancing doesn't work as described situations.

Usually load balancing only works when you download multiple files at the same time using "internet download managers" . Web browsing activities will actually bring you many troubles, however.
