TUN-300

The Tek Republic TUN-300 USB 3.0 Gigabit network adapter adds a RJ45 Ethernet port to any USB-enabled PC. The USB 3.0 maximizes network access speeds and provides up to 5GBps at USB 3.0 bus levels. The TUN-300 is a compact USB 3.0 network adapter that is backwards compatible with older USB 2.0/1.x computer systems (speed limited by USB bus), which makes it the ideal portable replacement network adapter. Also, with support for features such as Jumbo Frames, VLAN tagging and Wake on LAN (WOL), the adapter is a versatile Gigabit network solution for home and business users alike.

5 out of 5 eggsWorks in Linux Install

Pros: No proprietary drivers needed. This works perfectly with your FSF-approved GNU/Linux distribution.

Cons: none

Other Thoughts: Buy this for your laptop if it doesn't have an ethernet jack. I use this in a Thinkpad S1 Yoga.

5 out of 5 eggsWorks

Pros: Works great as it should. so far for a few days now it's been great.

Cons: I can't get it to work on linux. No ready prebuilt drivers, but no problem because on windows 10 it works flawlessly.

Other Thoughts: to take advantage of this make sure to use it on a usb 3.0. :)

3 out of 5 eggsWorks well, but...

Pros: Functions as expected

Cons: Requires driver downloads

Other Thoughts: This product, once working, does its job flawlessly. The problem is, at least on Windows 7, it's not plug-and-play. You actually have to download and install drivers for it. Now, if you think about it... that means that this device, which you presumably purchase so you can get online, requires internet access in order to use. We bought a few at once, and so I saved the drivers to a flash drive that I keep with the adapters, so folks in the office can just grab the device along with the flash drive to be up and running. But that's a bit of a pain, so we won't be buying more of these.

5 out of 5 eggsWorks VERY well wiht no hassles on Windows PC's

Pros: Speed is much better than what I thought it would be. Expected it to be slower, but this rocks. Used on a bunch of machines (windows 10) without a problem. All too often this dongles do not work as documented but this one does. Also works under Linux Ubuntu/Mageia. This is a pleasant surprise - no drivers had to be installed!

Cons: None

Other Thoughts: Great product! Would recommend it highly!

5 out of 5 eggsVery pleased - would buy it again

Pros: Very fast. I thought the performance would be poor, but it pushes Gigabit Ethernet to full speed. When inserted, drivers and setup occurred automatically, as expected. I have used this on 3 laptops (Toshiba, 2 Lenovo) for doing backups at full speed. Have also used it on desktops for the fun of it and this adapter rocks!

I am installing it on a Linux Ubuntu server running pfSense in a VM. Tried it without installing drivers and it would not see it on reboot. Had to disconnect and then reconnect it before it would be seen. Have downloaded the drivers from TEKRepublic's web site and will see how they work.

Cons: None so far. I should have bought 2 of them. :-(

4 out of 5 eggsGreat little adapter

Pros: it just works. plug into a usb 3 slot, win7/8/10 auto detects, plug in ethernet cable & boom! gigabit speeds.
I carry this with me when i run into a situation where i have a PC that needs gigabit speeds to move data quickly over a 100FE connection. I use it with my ultrabook that doesn't have an ethernet port to connect to wired networks where wifi isn't available.

Cons: it's a bit flaky with macs. it doesn't like my macbook air & only works 3 out of 10 times or so that i've tried. tried it with a mac pro and it works like a champ.

Other Thoughts: keep in mind, it could just be an issue with my macbook air. if you are buying for use on PCs i think you'll be pleased. if buying for a mac, just get a thunderbolt adapter.

1 out of 5 eggsnot happy

Pros: good concept

Cons: stopped working after an hour.....junk

Other Thoughts: would give it a zero rating if i could. bought this for a friend who lives in another state from me. died on her after using it about an hour. cable tech came out to her house to make sure her modem was working and he said the problem was the tek adapter. will not bother with a return since my friend lives in another state and is disabled which would create a hardship for her to find a ups since she cant drive. will probably not buy from newegg anymore even though ive been a long time customer. selling cheaply made items has soured me.

1 out of 5 eggsdisappointed

Pros: good concept

Cons: not made to last....worked great for an hour.

Other Thoughts: bought this for a friend and it worked for an hour and then died. thought it was a modem problem but cable tech said it was the adapter. not worth the time and hassle of returning this junk to get my 20 bux back.

5 out of 5 eggsworks great

Pros: Worked on Asus Chromebook Flip and Windows 7 ThinkPad. Vendor website has drivers for many OSs.

Cons: None

Other Thoughts: Interesting that WiFi was automatically disabled on the Chromebook when this adapter was plugged in. Windows 7 had to be configured to auto-install drivers from Windows Update. Without that, the driver install failed. No big deal.
