The problem: The first picture shows the problem: a 1Gbps connection that only reaches just over 300Mbps, with a wired connection. Having checked every piece of equipment between modem and motherboard, including running a CAT 7 cable directly between the two the problem was finally identified as a dodgy Intel chipset on the ASUS B550-F motherboard. In other words the onboard LAN was just unable to deliver the full broadband speed - and had been delivering substandard speeds for some time. The solution: pictures 2-4: a NICGIGA 2.5Gbps PCI-E card with a Realtek chipset. Why this card? Well, simply put, it has a black backplate that fits in with the motherboard's black backplates. I know, not the best reason but it also has a known chipset, a decent heatsink on the main chip, an handle over the 1Gbps bandwidth, future-proofs to a certain extent and is at good price point. (A quick note about the future-proofing: a 1 Gigabit connection can potentially deliver over 1Gbps - up to 1.3Gbps - whereas a 1Gbps card stops at 1Gbps. This card is 2.5Gbps and so will handle over 1Gbps and provides some future-proofing for when the next major speed increase comes in.) Install: was really simple: unscrew a backplate, install the card, screw in the card, close the case and plug in a CAT 7 cable bought at the same time - KINBETA high speed 10Gbps 2 metre CAT 7 flat braided cable - and switch on PC. See pictures 6-8. The result: picture 9 shows the result. As soon as the PC started the card was recognised, no driver download was needed. The download speed jumped from 321.5Mbps to 925Mbps (picture 9) solving the problem in a most elegant way. It is interesting to note that the ping was 9ms both before and after upgrading the NIC and upload also remained the same - the 52Mbps which was the expected speed and initially highlighted the problem. For those with a small form factor PC it is worth noting that a smaller backplate is provided (see picture 5) as well as a screwdriver and two screws. Overall very happy with this purchase it solved the problem at a reasonable cost and I can feel the difference the higher speed connection makes. Definitely recommend this card.

My internet connection is stable and runs at full speed. I even get the 2,5gbs intranet connexion from my router. My internet plan is only 100mbs so that doesn't benefit of the full 2.5gbs obviously but maybe in few years I'll get an optic fiber connection that will take advantage of that pciE card. This was easy to install and has no Cons or whatsoever. ## Frequently Bought Together - NICGIGA 2.5G Base-T PCIe Network Adapter, Realtek RTL8125B 2.5Gbps/1Gbps/100Mbps PCI Express Gigabit Network Card Convert to Ethernet RJ45 LAN Port for Gaming/Office, Support Windows/Linux - 5 Port 2.5GB Ethernet Switch Unmanaged Network Switch | 5 x 2.5 Gigabit | 1 x 10G SFP+ | Multigig Switch 10-100-1000Mbps | 45G Bandwidth | Plug & Play | Fanless Metal Internet Switch | NOT Support VPN - UGREEN 2.5Gb USB to Ethernet Adapter - Aluminum, USB 3.0 to RJ45 Dongle for Laptop, Compatible with MacBook, XPS, Windows, macOS --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/408002582-nicgiga-2-5g-base-t-pcie-network-adapter-realtek-rtl8125b](https://www.desertcart.tw/products/408002582-nicgiga-2-5g-base-t-pcie-network-adapter-realtek-rtl8125b) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-20*
