PEGATRON - trying to update to 2.5gb ethernet realtek but PC will not go past 1gb. HP h8-1080t

[jpj1]

I have an HP h8-1080t desktop tower and it has a pegatron 2a86 motherboard. It comes with Realtek 1gb ethernet and I was able to get another realtek 2.5gb ethernet installed via PCIe slot and system see it but the system will not go past 1gb for speed test. I wonder if it is due to motherboard limitation. Any idea? I disabled everything in properties for the 2.5gb but no luck.

Hi @jpj1 

Welcome back.

Internet data throughput via your modem would be limited to your Internet Service Provider agreement.

I would also think local network traffic would be limited by your router or other devices connected to your local network.

It would not be possible to move data on either network at up to 2.5 Gbps if you have a hardware bottleneck.

I have a couple of PCs with 2.5 Gbps ethernet adapters. I get ISP download speeds at up to 950 Mbps on good days.

Thanks for the comments.

Just to add some additional information, my router/modem is nokia ONT-XS2426 and when I do the speed test within the nokia app, I get 2.5gb. So, I know it is getting 2.5gb fiber speed.

However, when I do the speed test on my PC via speedtest.net, I always get less than 1gb. (900mbs etc)..

I got the realtek RTL8125B (2.5g base T PCIe network card) and it fit fine on the PCIe slot within the motherboard and when I go to network settings, I see it is functioning fine and I see it has latest drivers and it is showing 2.5gb for the speed. Only drawback is the speed when testing will never go past 1gb..

I highly suspect it is the motherboard limiting me to 1gb.. It has a realtek 1gb ethernet already and I disabled it so that it wouldn't interfere. In the end, the PC is too old to handle anything past 1gb...

Hi @jpj1 

My pleasure.

Yes, it looks you have a MB problem (hardware).

My problem is: I don't have a Fiber connection. I am limited to less than 1000 Mbps.

I've also have some older hardware on my network which will choke data transfers.

Adding this as an after thought: There are so many variable involved when measuring Internet speed.

This situation (measuring data throughput) reminds me of the paradox encountered by physicists when determining if photons are waves or particles.

Thanks again.. Yeah, the mouth is ready for all the food in the world (2.5gb) but the motherboard (stomach) is very tiny so it can only take a fraction at a time (1gb). 🙂

Currently there is a push to get fiber everywhere so hopefully it will happen in your area. We just got it and it has been 20 years..

hi @jpj1 

My pleasure.

I'm hoping for Fiber as soon as possible.

Cable internet isn't that bad. I can download a Windows .ISO in about 3minutes.
