During a Windows 10 reset, your internet speed dropped from 1 Gbps to 100 Mbps.
Lately had to reinstall Windows 10 because my old SSD reached its end of life and got replaced. I installed Windows 10 Pro N but faced some problems, so I switched back to just Pro. This took about a couple of hours. Earlier, around 1-2 years ago, I experienced the same problem before. I had a 1Gbps connection that worked at 100Mbps. I contacted my internet provider who suggested changing Speed & Duplex settings from Auto Negotiation to 1.0 Gbps Full Duplex, which resolved the issue then. On older Windows 10 and N versions it worked fine, likely using Auto. Now, during the new installation if I set 1.0 Gbps, the network cable disconnects immediately without recovery. My setup looks like this: - Fiber into the optical receiver (pic01) - From the receiver into the gpon terminal via optic fiber - Then directly to my PC using a standard network cable. Any suggestions?
Consider switching to a different CAT5 cable between that Huawei device and your PC. If you have a gigabit-enabled network card, auto-negotiation should function properly. It might be an issue with the cable restricting speed to 100Mb/s. In typical twisted pair cables, there are eight wires, but only four are required for 100Mb/s while all eight are needed for 1Gb/s.
I experienced comparable problems with Windows 10 before. I attributed them to outdated drivers and unsupported components. My suggestion is to visit the manufacturer’s website directly for updated drivers. If unavailable, investigate the chipset the network card uses and consult the chipset provider’s site. For instance, if it's an Intel chipset, compatible drivers from Intel may help. Also, examine the connections between your device and router. Look for any sharp bends in the cables that might interfere. Ensure cables are kept away from power lines, as this could cause interference. 110V lines are usually fine, but Ethernet should stay clear of electrical areas to avoid EMI. If possible, test another cable to determine if it resolves the issue.
It seems you're confirming your earlier observation about the cable. I've tried a budget version and it worked out the same. This is the third time I've changed the cable. I'm puzzled by the recurring failures. The last one I used was a CAT 6A outdoor model with reinforced wiring and plastic casing. I've kept it in place and never disturbed it, even after purchasing higher-quality self-crimping cables. Still unsure why it keeps breaking down.
