I am not sure if it's working. I just hope it never trips.As a adapter, it does the job though. One thing I noticed, is I plugged one via my decoder (fibre to data) to the router and then basically router to my PC. This seem to work and wired connection is good BUT weird enough wireless speeds falls by about 20Mbps.The other settings is connecting the 2 adapters together, the rj45 cable from my router to my PC is about 20m say. This actually didn't work, there weren't internet connection, Strange. Must be my fault somewhere, didn't bother to adjust or check it a 3rd time.Basically the 1st picture shows the adapter use between the decoder and the router. 2nd picture between the router and my PC. This will be the former setting I described above.Wired connection with the former setting is good. It's the maximum speed stipulated by my ISP. I use the wired setting though and really pray there is no surge to actually find out if this device works at all. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/177334641-sinloon-rj45-lan-coupler-adapter-surge-thundering-protector-gigabit-1000mbs](https://www.desertcart.sg/products/177334641-sinloon-rj45-lan-coupler-adapter-surge-thundering-protector-gigabit-1000mbs) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-22*
