Product Manuals

Q: will this work with the nintendo switch?

A: It will not work with a switch. Don't believe the sales people if they tell it will! Shame on best buy and shame on nintendo!

Q: Is this Ethernet Adapter compatible with the switch? In the description it only works on select devices though I would assume this product is compatible becuase unlike insignia's adapters, you don't need to insert a disk.

A: I legitimately just purchased this from Best buy.. unfortunately it is not compatible with the switch. I believe it has the wrong chipset but I cannot confirm this.. I do however know that it doesn't work.

Q: Will this ethernet adapter plug in to my TV USB port?

A: You could try it. Take it back if it does not work. WHY? It will be based on the Manufacture of the TV allowing the USB port to handle Ethernet.. I repeat. The maker of the TV has or has not programmed the USB port to accept the Ethernet connection on that port. I bought an Audio Streamer that only had a USB connection. This Ethernet Adapter worked great. It is a full-time connection to a corporate network and it has been running good for weeks. Have bought two.

Q: Where can I download a driver for it to work with Windows 7 .... my computer sees it as an unknown device with no driver

A: This adapter works with Windows 10.

Q: I bought this adapter as "Open Box" at my local Best Buy. There was no manual or instructions included in the box. The box states that it is "Plug and Play" Am I correct in assuming that I do NOT need to download a driver for the adapter to work?

A: I will work when just plugging it into a usb port with windows 10 and windows 11 it is a Realtek USB GbE Family Controller, the driver for older systems then win 10/11 is here https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-usb-3-0-software

Q: Can I use it to connect my Lenovo laptop to internet router?

A: Yes, this adapter works for most computers with USB 3.0 port and routers with Ethernet port.

Q: Is there a limit on the mbps download and upload speeds this can manage?

A: This adapter supports up to 1000Mbps.

Q: Is this adaptor compatible with a HP envy laptop?

A: Yes, this is compatible with an HP Envy Laptop.

Good data tool
Gets the job done. Need to test a router or firewall with a surface tablet? This here device is the boi you need. Unless you have the surface dock then use that. Otherwise 10 outta 10.

Must have tool for IT Professionals
100% Compatible w/ Windows 10 Pro (v1809) - An absolute perfect accessory, or upgrade from a lesser quality, poor performing, or broken on-board NIC/LAN card. Superb build quality as expected from Platinum products. Totally seamless integration/installation on Windows 10. Plug & Play defined. This device has already exceeded expectations in just a few weeks of use. I've used it on a Lenovo laptop where the older on board NIC card was problematic enough that when connected to a switch in our corporate environment, the card was negatively impacting performance of other devices. I had resorted to using wifi, but not any longer now that I have this USB 3.0 to Gig Ethernet adapter. Also tested on a desktop (pictured) where I was able to use/install in a matter of seconds. Its a wonderful device to have on hand if you are in the IT business and need to fix an issue, or just to troubleshoot network issues on a day in/out basis. Highly recommended - don't skimp on some cheap amazon.com garbage - this is worth every penny!

Makes a big difference vs. using WIFI - very fast
I have a 1.5 year old MacBook Air and I've always just used it on WIFI. So it was interesting to test this device on the MacBook Air, as I am used to a certain speed since I use this computer daily. I found that using both a VPN, and Tunnelblick, I was able to achieve much faster speeds than normally what I get on WIFI. And my WIFI mesh router system is very advanced and very current. Turns out, this MacBook Air runs much faster using this little adapter. I didn't realize how much faster until I actually plugged in. To use this, I simply plugged in a network cable, strung it over to my favorite chair, and then plugged in the adapter. I turned off WIFI to make sure what I was using was the network connection. There were no pop ups or driver messages, it just worked. And that is on a MAC. So, plug and play, literally. Speed increased in page loads and millisecond response times when using a speed test website. I would never have figured that hardwired was going to be noticeably faster than WIFI - but it is. While WIFI is more convenient, to get the most of the speed you have, wired is certainly faster. And I don't have any adapters I'd need to use with my MAC to get a wired connection, so it was interesting how easy this was to use. Certainly if working at a desk near an internet wired connection, this is a great choice to increase your throughput. I think about being on travel and on the hotel network, also think about kids in college that are working at a desk that has an internet connection available. Or any home office that has a router nearby, but such as on a MacBook Air or any computer that doesn't have an ethernet jack built in like they used to have. Oh yes, before I forget, the adapter does have network lights on it, so you know that (1) you are connected and (2) that data is transmitting back and forth. This is important and I almost forgot to mention.
