Review: Failed after six months; Dissapointing - UPDATED! I'm an idiot! - Edit: Okay, sooo I feel pretty stupid, because I'm pretty tech savvy but this one slipped by me. My router broadcasts two wireless networks - a standard one and the 5g. They are essentially named "Standard WiFi" and Standard WiFi_5G". You guessed it. Somehow my rig decided to connect to the standard with 10mbps instead of the 5g with 600mbps. Router still operational. User error. Updating my review and leaving my error here in hopes that it might help someone else. ORIGINAL REVIEW: When I first purchased it, the product was amazing. Powerful signal at amazing speeds. I have 1gig internet, and was getting a consistent 750-800mbps around the apartment.I was pretty blown away, and was thrilled that I wouldn't have to run an Ethernet cable to my comp. Unfortunately, after six months, the device speeds are abysmal. After comparing it to speed test with wired Ethernet and other wi-fi devices, I am incredibly disappointed. Speeds are roughly 10% of what they were and ping is through the roof. I went through all of the manufacturers recommendations, including updating drivers and removing power throttling and nothing. For the price, I had hoped for better. Just another company making an inferior product to save a dime. Review: This thing rocks and is worth 5 stars if you don't let a Windows Setting hold you back! - This thing rocks and I get the speed and reliability it advertises. It is also able to negotiate and work in areas other normal USB WIFI devices cannot. I usually do gaming with a hard wired connection but I decided to see how it would be if I just used wireless. It worked flawlessly and my experience was the same. Ran LAN tests and it ran with flying colors so if you have internet issues I wouldn't be too quick to blame the device. I have noticed a lot of complaints about it dropping out but this type of problem is not unique to this USB device. It can happen to almost all brands and it is not their fault. In almost all cases a Windows setting is to blame not the device. In Windows if you go to Device Manager > Network Adapter > TRENDnet TEW-809UB AC1900Wireless USB Adapter > Right Click > Select Properties > Power Management > and uncheck 'Allow the computer to turn off this device to save power' > Hit OK and reboot you will be rocking steady for the life of the device. If you still have some issues I would investigate other things before being quick to blame this device. The Internet Modem or stability of the ISP network play a big factor as well. Another thing that is good to do is download an App and analyze the WIFI channels in your area to see if someone is saturating your signal and adjust your router accordingly. In summary I love this thing and would recommend it to others. In most cases you can achieve the 5 stars you desire with this device and others if you adjust the windows setting above. I even attached a Picture for reference. The guy who created and buried this setting in the Network Adapter and made it default is the one that should get some stars docked. I mean, who would ever want their network devices to be shut off by default and without their knowledge? Sure, if someone wants to shut off their adapter then by all means leave the option for them to go in and check the box, but don't force it on someone. My heart goes out to the Millions of poor souls who just want a stable wireless network and this little bright idea caused them to lose hair, scream profanities, and assume it was the device. I also feel sorry for the Companies that build rock solid equipment only to have a buried windows setting they don't control turn off their device and render it unstable and useless for their customers. That is not to say a Company wont have an occasional device break ranks and have issues or some accident we don't see that renders it useless in transit but that is what returns and a second chance is for. Don't let that windows setting ruin your dreams and hold you back from giving this thing 5 stars. ## Features - UPGRADE YOUR WIFI PERFORMANCE: Upgrade your computer up to 1300 Mbps WiFi AC or 600 Mbps WiFi N to surf, game, and stream 4K HD video. - NDAA + TAA COMPLIANT: With our NDAA and TAA compliant Wireless AC, you can plan and install networking solutions that Government customers demand today (U.S. and Canada Only) - MANUFACTURER PROTECTION: We stand by the quality of our products.The TEW-809UB AC1900 High Power Dual Band Wireless USB Adapter is backed and supported with 3 years of TRENDnet Manufacturer Protection. - RELIABLE TECH SUPPORT: Our team of advisors, support and tech experts are English speaking, and available for all your needs during normal business hours.

Adrian TRENDnet Direct CS **Q: What kind of upload speeds are owners getting with this device? I recently purchased it and I get 250mbs download but a mere 5mbs upload. help.** A: Upload speed is determined by your internet service provider (ISP). It will not be specific to the device itself. I have hard-line internet to all my computers in my home. The hard lines can support 1000mbps in either direction, but my ISP gives me 200mbps download and about 12mbps upload. Typically when an ISP advertises your internet speed, they target the advertisement of the download speed, with a much slower upload speed. If your AC1900 device can download 250mbps, it can definitely upload at that speed, but your ISP caps your upload at 5mbps. You could maybe call your ISP and ask if there are options for faster upload. You can test the device itself by doing a file transfer to and from another device on your same WiFi network. For instance if you have two computers and they’re both connected to WiFi, you do a file transfer from the 1st to the 2nd, then again from the 2nd to the 1st. The speeds should all be identical and depending on the size of the file transferred, you’ll see the maximum transfer speed of the device itself. For example, my hard line connection supports 1000mbps in both directions. When I run a speed test of my internet service I get 200 down and 12 up, but when I do a file transfer from one hard line device to another hard line device in my home network, I get roughly 1000mbps in either direction. Think of the device speed like a highway that has a 1000mph limit, but when you access the web, you’re given two cars provided by your ISP. The first car takes internet traffic to your devices from the web (download) and the second car takes information from your devices to the web (upload). The first car is a sports car and while it can’t max out the speed limit, it’s still pretty fast. The second car, however, is a jalopy, and barely moves at all. The payment you give your ISP determines what two cars they give you. Some ISPs can give you the same car for both. That is, your download and upload speeds are the same. This is not the standard most the time, however. TL;DR - Call your ISP and upgrade your service if you want better upload speeds. It’s not the device that’s causing the slowness. **Q: Can i use this to create a windows mobile hotspot (transmitter) from my wired pc to nearby mobile devices?** A: Dear customer! Thanks for your interest in TRENDnet! No, you can't use this to create a windows mobile hotspot (transmitter) from your wired pc to nearby mobile devices. Hope this helps! If you have any more questions, you can always respond directly to this thread and someone will be happy to try and help answer any additional questions you may have! Have a great day!

The TRENDnet AC1900 High Power Dual Band Wireless USB Adapter (model TEW-809UB) promises speedy connections and wide coverage, but is it all sunshine and rainbows? Let's dive in: ■ Positives: - Blazing Speeds: Say goodbye to buffering! This adapter boasts up to 1300 Mbps on the 5GHz band and 600 Mbps on the 2.4GHz band, making it ideal for streaming, gaming, and downloading. - Signal Strength on Steroids: The high-powered radio and detachable antennas work together to amplify your Wi-Fi signal, reaching even those pesky corners of your home. - Dual Band Advantage: Switch seamlessly between the 5GHz band for lag-free gaming and the 2.4GHz band for better wall penetration, ensuring a consistent connection. ■ Negatives: - Built Like a Tank (But Not Always in a Good Way): This adapter is no lightweight. Its bulky design and large antennas might not be everyone's cup of tea, especially for laptops. - Short Leash: The included USB cable is on the shorter side, limiting your placement options and potentially requiring an extension. I- nconsistent Long-Range Performance: While the signal boost is impressive, some users report occasional dips in performance at longer distances, depending on your home's layout and obstacles. ■ The Verdict: The TRENDnet AC1900 is a powerful adapter that can significantly improve your Wi-Fi experience, especially for streaming and gaming. However, its bulky design and occasional long-range hiccups might be dealbreakers for some. If you prioritize portability and a more consistent signal at greater distances, consider exploring other options. Ultimately, the choice is yours!
